Why We Should Eat More Beans

Why You Should Eat More Beans

We’ve known for decades that beans have an exceptionally low glycemic index. You give someone cooked beans, peas, or lentils and they don’t even get half the blood sugar spike that they would get with the same amount of carbs in the form of bread, pasta, or potatoes. So if you’re going to eat some high glycemic food like white rice, consider having some beans with it, and the more beans the better. If you check out my 3-min video Beans and the Second Meal Effect, you can see that as the subjects’ bean to rice ratio increases, cardiometabolic risk factors continually improve. Substituting one serving of beans for one serving of white rice was associated with a 35 percent lower risk of metabolic syndrome (pre-diabetes).

Why do beans have such a low glycemic index? Maybe it’s because they’ve got so much fiber that absorption is just slower or something? It was this study that blew everyone’s minds.

It started about as expected. Give people bread for breakfast, and they get big spikes in blood sugar and insulin levels, but give the same amount of carbs in lentil form and you blunt the effect. (Lentils for breakfast? Well, the Brits like baked beans on their toast, but I’ve started using a handful of sprouted lentils in my breakfast smoothie. See A Better Breakfast and Antioxidants Sprouting Up). What they did different, though, was follow through to lunch.

For lunch both groups got the same meal; they both got bread. Those that had lentils for breakfast, though, had less of a glycemic reaction to the bread. At the time they called it the “lentil effect,” but subsequent studies found chickpeas appear to work just as well. It has since been dubbed the “second meal effect.” Eat lentils for dinner, and then for breakfast, even if forced to drink sugar water, we have better glycemic control. Beans moderate your blood sugar not just at the meal we eat them, but even hours later or the next day.

How is that even possible? The mystery has since been solved. Remember what our gazillions of gut bacteria do with fiber? They produce compounds like propionate with it (see Fawning Over Flora and Boosting Good Bacteria in the Colon Without Probiotics) that get absorbed into our system and slow down gastric emptying—the rate at which food leaves our stomach—so we don’t get as much of a sugar rush. It’s like symbiosis. We feed our good bacteria and they feed us back. So, we have a bean burrito for supper and by the next morning it’s time for our gut bacteria to eat that same burrito and the by-products they create may affect how our breakfast is digested.

Researchers figured this out by giving people rectal infusions of the amount of propionate your good bacteria might make from a good burrito, and the stomach relaxes within minutes. I guess if you forgot to eat any kind of beans for supper and need to blunt the effect of your breakfast doughnut, it’s theoretically not too late—but in general I encourage people to administer their food orally

Avoiding Cholesterol Is a No Brainer

Eggs and brains are the two most concentrated sources of cholesterol in the diet.

Egg Industry Caught Making False Claims

Egg Industry Caught Making False Claims

On the basis of concerns from the American Heart Association and consumer groups, the Federal Trade Commission carried out successful legal action—upheld by the Supreme Court—to compel the egg industry to cease and desist from false and misleading advertising that eggs had no harmful effects on health.

Over the years, cholesterol concerns resulted in severe economic loss through a reduction in egg consumption, so the egg industry created a “National Commission on Egg Nutrition” to combat the public health warnings with ads that said things like “There is no scientific evidence whatsoever that eating eggs in any way increases the risk of heart attack.” The U.S. Court of Appeals found such outright deception patently false and misleading.

Even the tobacco industry wasn’t that brazen, trying only to introduce the element of doubt, arguing that the relationship between smoking and health remains an open question. In contrast, the egg ads made seven claims, each of which was determined by the courts to be blatantly false. The Court determined the egg industry ads were “false, misleading, and deceptive.” Legal scholars note that, like Big Tobacco, the egg industry did more than just espouse one side of a genuine controversy, but flatly denied the existence of scientific evidence.

Over the last 36 years, the American Egg Board has spent hundreds of millions of dollars to convince people eggs are not going to kill them—and it’s working. From one of their internal strategy documents that I was able to get a hold of: “In combination with aggressive nutrition science and public relations efforts, research shows that the advertising has been effective in decreasing consumers concerns over eggs and cholesterol/heart health.”

Currently, they’re targeting moms. Their approach is to “surround moms wherever they are.” They pay integration fees for egg product placement in TV shows. To integrate eggs into The Biggest Loser, for example, could be a million dollars, according to their internal documents. Getting some kids storytime reading program to integrate eggs may only take half a million, though. The American Egg Board keeps track of who is, and is not, a “friend-of-eggs.” They even pay scientists $1500 to sit and answer questions like, “What studies can help disassociate eggs from cardiovascular disease?”

From the beginning, their arch nemesis was the American Heart Association, with whom they fought a major battle over cholesterol. In documents retrieved through the Freedom of Information Act featured in my 6-min video Eggs and Cholesterol: Patently False and Misleading Claims, you can see even the USDA repeatedly chastises the egg industry for misrepresenting the American Heart Association position. In a draft letter to magazine editors, the egg industry tried to say that the “American Heart Association changed its recommendations to approve an egg a day in 2000 and eventually eliminated its number restrictions on eggs in 2002,” to which the head of USDA’s poultry research and promotion programs had to explain that the “change” in 2000 wasn’t a change at all. Nothing in the guidelines or recommendations was changed. What happened was that in response to a question posed by someone planted in the audience, Heart Association reps acknowledged that even though eggs are among the most concentrated source of cholesterol in the diet, an individual egg has under 300mg of cholesterol and could technically fit under the 300 mg daily limit. In 2002, they eliminated the specific mention of eggs for consistency sake, but the American Heart Association insists that they haven’t changed their position and continue to warn consumers about eggs.

The guidelines on the AHA website at the time explained that since one egg has 213 and the limit for people with normal cholesterol is 300 you could fit an egg in if you cut down on all other animal products. If you have an egg for breakfast, for example, and some coffee, some skinless turkey breast for lunch, etc., you could end up at over 500 by the end of the day, nearly twice the recommended limit. So if you are going to eat an egg, the Heart Association instructed, we would need to “substitute vegetables for some of the meat, drink our coffee black, and watch for hidden eggs in baked goods.” Furthermore, the limit for folks with high cholesterol is 200mg a day, which may not even allow a single egg a day.

This is how the senior director of nutrition education at the American Egg Board’s Egg Nutrition Center characterized the American Heart Association guidelines: “Maybe I’m being overly sensitive, but this reads like: ‘If you insist on having those deadly high cholesterol eggs your penalty will be to eat vegetables and you can’t even have the yummy steak and creamy coffee you love. Really it’s not worth eating eggs. Oh, and if you think you’ll be able to enjoy some delicious baked goods, forget it, the deadly eggs are there too!’”

How Toxic is Sugar

How 'toxic' is sugar?

Emerging research suggests that sugar may be linked to deadly diseases, but Health Canada’s current food labelling regulations make it tough for Canadians to get an easy picture of how much of the sweet substance they are consuming — and it doesn’t look like that’s going to change any time soon.

The groundbreaking and controversial research explored by the CBC’sthe fifth estate in its season premiere tonight links sugar to diseases ranging from diabetes to cancer and Alzheimer’s.

“Sugar is toxic beyond its calories,” Dr. Robert Lustig, an expert on childhood obesity at the University of California, San Francisco, told the fifth estate’s Gillian Findlay.

Watch The Secrets of Sugar on the fifth estate on CBC-TV tonight at 9 p.m.

 

While Canadians have become used to warnings about the dangers of consuming too much fat or salt, nutrition labels on food have never included recommended daily limits specifically for sugar.

Health Canada does not have a recommended limit for how much sugar Canadians should consume in a day.

A representative of Food and Consumer Products of Canada, an industry organization that represents the largest food companies in the country, says it sees “no need” for a recommended daily limit on sugar intake.

Health Canada declined numerous requests by the fifth estate for an interview, but former Health Canada employees did speak off the record, and said the department does not think that sugar should be singled out as a major culprit behind chronic diseases.

Stirring up debate

According to Statistics Canada, the average Canadian consumes 26 teaspoons of sugar per day. That works out to 40 kilograms per year —– or 20 bags.

While neither the Canadian nor U.S. governments has a recommended daily limit for sugar consumption, one major U.S. medical group is recommending people cut back on the sweet substance.

The American Heart Association is suggesting men consume no more than nine teaspoons a day. For women, the recommendation is a maximum of six teaspoons.

Dr. Robert LustigDr. Robert Lustig, as expert on childhood obesity at the University of California, San Francisco, says ‘sugar is toxic beyond its calories.’ (CBC)

That recommendation comes as research from a small but influential group of medical researchers is stirring up debate on the impact sugar has on health.

One of the most vocal of those researchers is Lustig, an author who has become a YouTube sensation for a 90-minute lecture in which he calls sugar a toxic poison.

“I use those words and I mean them. This is not hyperbole. This is the real deal,” he told Findlay.

“Everyone thinks that the bad effects of sugar are because sugar has empty calories. What I’m saying is no, there are a lot of things that do have empty calories that are not necessarily poisonous.”

Breaking down the sugar

Lustig says that sugar, which is made up of glucose and fructose molecules, is a poison because of the way our bodies break it down.

“When you metabolize fructose in excess, your liver has no choice but to turn that energy into liver fat and that liver fat causes all of the downstream metabolic diseases.”

But not everyone agrees with Lustig’s theory, including other doctors and food industry representatives.

Dr. John Sievenpiper, a researcher at St. Michael’s Hospital in Toronto, questions Lustig’s methodology and his view that “sugar and only sugar” is the prime factor in the international food supply that “predicts [the] diabetes rate worldwide.”

Sievenpiper notes that during the same time period when Lustig points to increasing sugar consumption and rising rates of obesity —– something that has been linked to diabetes — there was also increasing consumption of bottled water.

‘We have to be careful in putting too much of the biological plausibility in wanting to believe patterns that we see.’– Dr. John Sievenpiper

“But there’s no real biological plausibility in the link between bottled water and [being] overweight and obesity. We have to be careful in putting too much of the biological plausibility in wanting to believe patterns that we see.”

Sievenpiper isn’t recommending people eat a lot of sugar, but he does suggest we should be careful about saying fructose is largely responsible for various health problems.

“As long as you match for calories, fructose does not behave differently than does any other form of carbohydrate, namely starches or fine starches and glucose. And that’s not to say that they’re benign, because I don’t think we should be having a lot of refined starch or glucose. But it’s not behaving any differently.”

Industry skepticism

A representative of Canada’s largest food industry association is also skeptical of Lustig’s research.

Phyllis Tanaka, vice-president of scientific and regulatory affairs for Food and Consumer Products of Canada, isn’t worried about Lustig’s claims about one of her industry’s key ingredients and doesn’t think consumers should be either.

Phyllis TanakaPhyllis Tanaka, vice-president of scientific and regulatory affairs for Food and Consumer Products of Canada, says her group has worked with Health Canada over the last few years on how to help consumers make ‘informed choices.’ (CBC)

“I think it’s important that we step back and look for ways to educate and help consumers fit sugar into a healthy dietary pattern,” she said.

But current food labelling regulation can make it difficult for consumers who want to avoid sugar.

On Canadian nutrition labels, manufacturers are required to list ingredients in order from greatest to least volume. But many labels list multiple kinds of sweeteners with different names. For example, honey, barley malt syrup and evaporated cane juice could all be listed separately, even though the human body treats them all as sugar.

Also, sugar is measured in grams on labels, instead of more consumer-friendly teaspoons. For someone trying to keep track of intake, four grams of sugar equals one teaspoon.

In a can of Coke, for example, there are more than 10 teaspoons of sugar. The popular “Healthy Choice” microwave chicken dinner has 5½ teaspoons.

Tanaka says her group has worked with Health Canada over the last few years on how to help consumers make “informed choices,” and that for those who want to avoid sugar, all the information they need is already on the label.

“At this point in time, I’m comfortable in saying the science just isn’t there to support a role in chronic disease.”

Pure White and Deadly

Reducing sugar intake

The World Health Organization is again urging people to lower the amount of sugar they eat.

The Geneva-based global health agency says getting daily sugar intake to below five per cent of one’s daily caloric intake would be optimal but reiterated that restricting intake to no more than 10 per cent is also good.

“We should aim for five per cent if we can … but 10 per cent is more realistic,” said Dr. Francesco Branco, head of nutrition for health and development for WHO.

The draft recommendations, which will likely be contentious, will be open for public comment for the rest of the month until March 31. Then the agency and scientific advisers will finalize the guidance.

“Sugar might become the new tobacco in terms of risk,” said Branco at a news conference in Geneva on Wednesday morning.

The 5 per cent rule

  • Five per cent of sugar intake daily is about 25 grams of sugar/day for an adult.
  • That is about six to seven teaspoons.
  • A can of Coke has more than 10 teaspoons of sugar.

Branco warned about the “sugars that we don’t see.”

“It’s sometimes in condiments, sauce added to meats, a tablespoon of ketchup has up to seven grams of sugar [and] sweetened yogurt up to six grams.”

The WHO has long urged people to limit sugar calories to below 10 per cent of their daily calories, but the five per cent target is new.

To put it into context, five per cent would be about six teaspoons of sugar a day; a can of sugar-sweetened soda contains about 10 teaspoons of sugar.

Branco was particularly concerned about pop drinks and children.

“An average serving at a fast food place of sugar-sweetened soda … approaches 30 grams of sugar per serving,” noted Branco. “That already exceeds the recommended daily serving for a child.”

He emphasized that if parents can limit their child’s intake to the five per cent mark, the child will have almost no tooth decay in addition to being healthier and unlikely to become overweight and obese.

Free sugars

The recommendations relate to what are called free sugars — those added by manufacturers, cooks or consumers. And they abound in prepared foods.
They relate to all monosaccharides — things like glucose and fructose — and disaccharides such as sucrose or table sugar, as well as sugars in honey, syrups, fruit juices and fruit concentrates.

The recommendations do not relate to “intrinsic” sugars — those built into whole foods such as fruits or vegetables.

The recommendations look at limiting sugar intake in relation to lowering the risk of obesity and dental decay, two conditions scientific studies suggest are linked to excess sugar consumption.

The report, from the WHO Department of Nutrition for Health and Development, says consideration was given to also looking at the evidence related to sugar intake and two other conditions — heart disease and diabetes. But in the end the focus remained on obesity and tooth decay.

Nutritional experts have been expecting new recommendations from the WHO.

In 2004 when the WHO tried to include the 10 per cent sugar limit recommendation in its Global Strategy for Diet, Physical Activity and Health, the U.S. Congress — under pressure from the sugar industry lobby — threatened to withdraw U.S. funding for the agency. The direct reference to the 10 per cent figure was removed from the final report.

No recommendations in Canada

In Canada, the Heart and Stroke Foundation has begun a consultation process to determine if it should recommend that Canadians restrict the portion of their daily calories that come from sugar.

Health Canada does not have a recommended limit for how much sugar Canadians should consume in a day.

‘We are woefully inadequate in the evidence around sugar consumptions for Canadians. Also the role of added sugars throughout all the processed foods.’– Dr. Tom Warchawski, Childhood Obesity Foundation

According to Statistics Canada, in 2004, the average Canadian consumed 26 teaspoons of sugar per day. That works out to 40 kilograms per year —– or 20 bags. Experts say that amount should not exceed 13 teaspoons per day, if sticking to the 10 per cent benchmark.

“We are woefully inadequate in the evidence around sugar consumptions for Canadians. Also the role of added sugars throughout all the processed foods,” Dr. Tom Warshawski told CBC News. Warshawski, a pediatrician, is also chair of the Childhood Obesity Foundation in Canada.

“Health Canada could not, in all fairness, have come out with more rigid guidelines because the evidence wasn’t there. But the evidence is coming so now we have to grasp it, study it and come forward with meaningful recommendations for the public.”

Current food labelling regulations can make it difficult for consumers who want to avoid sugar.

On Canadian nutrition labels, manufacturers are required to list ingredients in order from greatest to least volume. But many labels list multiple kinds of sweeteners with different names. For example, honey, barley malt syrup and evaporated cane juice could all be listed separately, even though the human body treats them all as sugar.

Also, sugar is measured in grams on labels, instead of more consumer-friendly teaspoons. For someone trying to keep track of intake, four grams of sugar equals one teaspoon. In a can of Coke, for example, there are more than 10 teaspoons of sugar.

The WHO’s Branco suggests that final recommendations from his organization “will have to be taken up through policymakers” in governments around the world.

“[Our recommendations] can be used to develop policies to provide healthier food in public institutions or it can be used in the context of public information campaigns but much more has to be considered.”

Eating Sugar Causes Massive Health Problems, Says WHO

TORONTO – The World Health Organization is again urging people to lower the amount of sugar they eat, suggesting there are health benefits to restricting so-called free sugars to less than five per cent of one’s dietary intake.

For the average adult, that would be about six teaspoons (30 millilitres) of sugar a day — less than the sugar contained in a single can of sugar-sweetened soda. For children, it could be as low as three teaspoons (15 ml) of sugar a day, said Dr. Francesco Branca, director of the WHO’s department of nutrition for health and development.

In draft recommendations issued Wednesday, the Geneva-based global health agency said people should limit their intake of sugar to no more than 10 per cent of their daily calorie intake, but if they could get to five per cent, that would be better.

“The five per cent would probably be the ideal one and the 10 per cent is the more realistic one,” Branca said in a teleconference for journalists.

Both would likely be a stretch for many Canadians.

Statistics Canada does not have data that teases out what proportion of Canadians’ calorie intake comes from free sugars versus intrinsic sugars.

Free sugars are sugars added to foods by manufacturers, cooks or the people eating the food — brown sugar on oatmeal, for example — as well as natural sugars found in fruit juices, honey, syrups and molasses. Intrinsic sugars are the sugars in whole foods like fruit; intrinsic sugars are not included in the WHO intake limit recommendations.

The sugar in an orange is intrinsic. The sugar in orange juice — freshly squeezed or from concentrate — is free sugar.

The most recent Canadian data, from the 2004 Canadian Consumer Health Survey, shows that on average Canadians consumed 110 grams of sugar a day that year — the equivalent of 26 teaspoons (130 ml) of sugar. Sugar calories made up 21.4 per cent of the average Canadian’s total calorie intake.

Didier Garriguet, a senior analyst with Statistics Canada, said because of the way the data were collected, there is no way to break out the free sugar intake from the total sugar intake. Garriguet said a nutritional survey planned for 2015 should provide a clearer picture of the breakdown of sugars in Canadians’ diets.

The WHO draft recommendations differ from earlier iterations in setting the target of less than five per cent. The less than 10 per cent recommendation has been WHO policy since the late 1980s.

The draft recommendations will be open for public comment for the rest of March, after which the WHO and scientific advisers will finalize the guidance.

The recommendations are likely to be contentious. And nutrition experts who have been waiting for the recommendations expect pushback from the food industry, which would need to dramatically reformulate products if consumers were to be able to meet the targets and still eat prepared and packaged foods.

In 2004 when the WHO tried to include the 10 per cent sugar limit recommendation in its Global Strategy for Diet, Physical Activity and Health, the U.S. Congress — under pressure from the sugar industry lobby — threatened to withdraw U.S. funding for the agency. The direct reference to the 10 per cent figure was removed from the final report.

Branca said he doesn’t anticipate the same degree of opposition this time.

But in an interview before the release of the draft guidance, Canadian obesity expert Dr. Yoni Freedhoff predicted the recommendations would lead to heated debate.

“There’s going to be fierce lobbying. Fierce, fierce, fierce.”

Sugars are added to many foods — things like breakfast cereals, sauces, baked goods and condiments. A tablespoon of ketchup, for instance, contains about one teaspoon (five ml) of sugar.

In addition to being ubiquitous, added sugars have many names — molasses, sucrose, fructose, anhydrous dextrose, malt syrup and honey, to name just some. So spotting exactly how much added sugar there is in prepared foods is no easy thing.

The recommendations look at limiting sugar intake in relation to lowering the risk of obesity and tooth decay, two conditions scientific studies suggest are linked to excess sugar consumption.

The report said consideration was also given to looking at the evidence related to sugar intake and two other conditions — heart disease and diabetes. But in the end the focus remained on obesity and tooth decay.

In Canada, the Heart and Stroke Foundation began a consultation process this week to determine if it should recommend that Canadians restrict the portion of their daily calories that come from sugar.

It is considering following the lead of the American Heart Association, which suggests that added sugars make up no more than half of one’s daily discretionary caloric allowance, which it says would be no more than 100 calories or six teaspoons (30 ml) a day for most American women and 150 calories a day or about nine teaspoons (45 ml) of sugar for men.

Sugar Love

(A not so sweet story)

Bottom of the Drink
They had to go. The Coke machine, the snack machine, the deep fryer. Hoisted and dragged through the halls and out to the curb, they sat with other trash beneath gray, forlorn skies behind Kirkpatrick Elementary, one of a handful of primary schools in Clarksdale, Mississippi. That was seven years ago, when administrators first recognized the magnitude of the problem. Clarksdale, a storied delta town that gave us the golden age of the Delta blues, its cotton fields and flatlands rolling to the river, its Victorian mansions still beautiful, is at the center of a colossal American health crisis. High rates of obesity, diabetes, high blood pressure, heart disease: the legacy, some experts say, of sugar, a crop that brought the ancestors of most Clarksdale residents to this hemisphere in chains. “We knew we had to do something,” Kirkpatrick principal SuzAnne Walton told me.

Walton, Clarksdale born and bred, was leading me through the school, discussing ways the faculty is trying to help students—baked instead of fried, fruit instead of candy—most of whom have two meals a day in the lunchroom. She was wearing scrubs—standard Monday dress for teachers, to reinforce the school’s commitment to health and wellness. The student body is 91 percent African American, 7 percent white, “and three Latinos”—the remaining 2 percent. “These kids eat what they’re given, and too often it’s the sweetest, cheapest foods: cakes, creams, candy. It had to change. It was about the students,” she explained.

Take, for example, Nicholas Scurlock, who had recently begun his first year at Oakhurst Middle School. Nick, just tall enough to ride the coaster at the bigger amusement parks, had been 135 pounds going into fifth grade. “He was terrified of gym,” Principal Walton told me. “There was trouble running, trouble breathing—the kid had it all.”

“Of course, I’m not one to judge,” Walton added, laughing, slapping her thighs. “I’m a big woman myself.”

I met Nick in the lunchroom, where he sat beside his mother, Warkeyie Jones, a striking 38-year-old. Jones told me she had changed her own eating habits to help herself and to serve as an example for Nick. “I used to snack on sweets all day, ’cause I sit at a desk, and what else are you going to do? But I’ve switched to celery,” she told me. “People say, ‘You’re doing it ’cause you’ve got a boyfriend.’ And I say, ‘No, I’m doing it ’cause I want to live and be healthy.’”

Take a cup of water, add sugar to the brim, let it sit for five hours. When you return, you’ll see that the crystals have settled on the bottom of the glass. Clarksdale, a big town in one of the fattest counties, in the fattest state, in the fattest industrialized nation in the world, is the bottom of the American drink, where the sugar settles in the bodies of kids like Nick Scurlock—the legacy of sweets in the shape of a boy.

Mosques of Marzipan
In the beginning, on the island of New Guinea, where sugarcane was domesticated some 10,000 years ago, people picked cane and ate it raw, chewing a stem until the taste hit their tongue like a starburst. A kind of elixir, a cure for every ailment, an answer for every mood, sugar featured prominently in ancient New Guinean myths. In one the first man makes love to a stalk of cane, yielding the human race. At religious ceremonies priests sipped sugar water from coconut shells, a beverage since replaced in sacred ceremonies with cans of Coke.

Sugar spread slowly from island to island, finally reaching the Asian mainland around 1000 B.C. By A.D. 500 it was being processed into a powder in India and used as a medicine for headaches, stomach flutters, impotence. For years sugar refinement remained a secret science, passed master to apprentice. By 600 the art had spread to Persia, where rulers entertained guests with a plethora of sweets. When Arab armies conquered the region, they carried away the knowledge and love of sugar. It was like throwing paint at a fan: first here, then there, sugar turning up wherever Allah was worshipped. “Wherever they went, the Arabs brought with them sugar, the product and the technology of its production,” writes Sidney Mintz inSweetness and Power. “Sugar, we are told, followed the Koran.”

Muslim caliphs made a great show of sugar. Marzipan was the rage, ground almonds and sugar sculpted into outlandish concoctions that demonstrated the wealth of the state. A 15th-century writer described an entire marzipan mosque commissioned by a caliph. Marveled at, prayed in, devoured by the poor. The Arabs perfected sugar refinement and turned it into an industry. The work was brutally difficult. The heat of the fields, the flash of the scythes, the smoke of the boiling rooms, the crush of the mills. By 1500, with the demand for sugar surging, the work was considered suitable only for the lowest of laborers. Many of the field hands were prisoners of war, eastern Europeans captured when Muslim and Christian armies clashed.

Perhaps the first Europeans to fall in love with sugar were British and French crusaders who went east to wrest the Holy Land from the infidel. They came home full of visions and stories and memories of sugar. As cane is not at its most productive in temperate climes—it needs tropical, rain-drenched fields to flourish—the first European market was built on a trickle of Muslim trade, and the sugar that reached the West was consumed only by the nobility, so rare it was classified as a spice. But with the spread of the Ottoman Empire in the 1400s, trade with the East became more difficult. To the Western elite who had fallen under sugar’s spell there were few options: deal with the small southern European sugar manufacturers, defeat the Turk, or develop new sources of sugar.

In school they call it the age of exploration, the search for territories and islands that would send Europeans all around the world. In reality it was, to no small degree, a hunt for fields where sugarcane would prosper. In 1425 the Portuguese prince known as Henry the Navigator sent sugarcane to Madeira with an early group of colonists. The crop soon made its way to other newly discovered Atlantic islands—the Cape Verde Islands, the Canaries. In 1493, when Columbus set off on his second voyage to the New World, he too carried cane. Thus dawned the age of big sugar, of Caribbean islands and slave plantations, leading, in time, to great smoky refineries on the outskirts of glass cities, to mass consumption, fat kids, obese parents, and men in XXL tracksuits trundling along in electric carts.

Slaves to Sugar
Columbus planted the New World’s first sugarcane in Hispaniola, the site, not coincidentally, of the great slave revolt a few hundred years later. Within decades mills marked the heights in Jamaica and Cuba, where rain forest had been cleared and the native population eliminated by disease or war, or enslaved. The Portuguese created the most effective model, making Brazil into an early boom colony, with more than 100,000 slaves churning out tons of sugar.

As more cane was planted, the price of the product fell. As the price fell, demand increased. Economists call it a virtuous cycle—not a phrase you would use if you happened to be on the wrong side of the equation. In the mid-17th century sugar began to change from a luxury spice, classed with nutmeg and cardamom, to a staple, first for the middle class, then for the poor.

By the 18th century the marriage of sugar and slavery was complete. Every few years a new island—Puerto Rico, Trinidad—was colonized, cleared, and planted. When the natives died, the planters replaced them with African slaves. After the crop was harvested and milled, it was piled in the holds of ships and carried to London, Amsterdam, Paris, where it was traded for finished goods, which were brought to the west coast of Africa and traded for more slaves. The bloody side of this “triangular trade,” during which millions of Africans died, was known as the Middle Passage. Until the slave trade was banned in Britain in 1807, more than 11 million Africans were shipped to the New World—more than half ending up on sugar plantations. According to Trinidadian politician and historian Eric Williams, “Slavery was not born of racism; rather, racism was the consequence of slavery.” Africans, in other words, were not enslaved because they were seen as inferior; they were seen as inferior to justify the enslavement required for the prosperity of the early sugar trade.

The original British sugar island was Barbados. Deserted when a British captain found it on May 14, 1625, the island was soon filled with grinding mills, plantation houses, and shanties. Tobacco and cotton were grown in the early years, but cane quickly overtook the island, as it did wherever it was planted in the Caribbean. Within a century the fields were depleted, the water table sapped. By then the most ambitious planters had left Barbados in search of the next island to exploit. By 1720 Jamaica had captured the sugar crown.

For an African, life on these islands was hell. Throughout the Caribbean millions died in the fields and pressing houses or while trying to escape. Gradually the sin of the trade began to be felt in Europe. Reformers preached abolition; housewives boycotted slave-grown cane. In Sugar: A Bittersweet History Elizabeth Abbott quotes Quaker leader William Fox, who told a crowd that for every pound of sugar, “we may be considered as consuming two ounces of human flesh.” A slave in Voltaire’s Candide, missing both a hand and a leg, explains his mutilation: “When we work in the sugar mills and we catch our finger in the millstone, they cut off our hand; when we try to run away, they cut off a leg; both things have happened to me. It is at this price that you eat sugar in Europe.”

And yet there was no stopping the boom. Sugar was the oil of its day. The more you tasted, the more you wanted. In 1700 the average Englishman consumed 4 pounds a year. In 1800 the common man ate 18 pounds of sugar. In 1870 that same sweet-toothed bloke was eating 47 pounds annually. Was he satisfied? Of course not! By 1900 he was up to 100 pounds a year. In that span of 30 years, world production of cane and beet sugar exploded from 2.8 million tons a year to 13 million plus. Today the average American consumes 77 pounds of added sugar annually, or more than 22 teaspoons of added sugar a day.

If you go to Barbados today, you can see the legacies of sugar: the ruined mills, their wooden blades turning in the wind, marking time; the faded mansions; the roads that rise and fall but never lose sight of the sea; the hotels where the tourists are filled with jam and rum; and those few factories where the cane is still heaved into the presses, and the raw sugar, sticky sweet, is sent down the chutes. Standing in a refinery, as men in hard hats rushed around me, I read a handwritten sign: a prayer beseeching the Lord to grant them the wisdom, protection, and strength to bring in the crop.

The Culprit
“It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar.”

Richard Johnson, a nephrologist at the University of Colorado Denver, was talking to me in his office in Aurora, Colorado, the Rockies crowding the horizon. He’s a big man with eyes that sparkle when he talks. “Why is it that one-third of adults [worldwide] have high blood pressure, when in 1900 only 5 percent had high blood pressure?” he asked. “Why did 153 million people have diabetes in 1980, and now we’re up to 347 million? Why are more and more Americans obese? Sugar, we believe, is one of the culprits, if not the major culprit.”

As far back as 1675, when western Europe was experiencing its first sugar boom, Thomas Willis, a physician and founding member of Britain’s Royal Society, noted that the urine of people afflicted with diabetes tasted “wonderfully sweet, as if it were imbued with honey or sugar.” Two hundred and fifty years later Haven Emerson at Columbia University pointed out that a remarkable increase in deaths from diabetes between 1900 and 1920 corresponded with an increase in sugar consumption. And in the 1960s the British nutrition expert John Yudkin conducted a series of experiments on animals and people showing that high amounts of sugar in the diet led to high levels of fat and insulin in the blood—risk factors for heart disease and diabetes. But Yudkin’s message was drowned out by a chorus of other scientists blaming the rising rates of obesity and heart disease instead on cholesterol caused by too much saturated fat in the diet.

As a result, fat makes up a smaller portion of the American diet than it did 20 years ago. Yet the portion of America that is obese has only grown larger. The primary reason, says Johnson, along with other experts, is sugar, and in particular fructose. Sucrose, or table sugar, is composed of equal amounts of glucose and fructose, the latter being the kind of sugar you find naturally in fruit. It’s also what gives table sugar its yummy sweetness. (High-fructose corn syrup, or HFCS, is also a mix of fructose and glucose—about 55 percent and 45 percent in soft drinks. The impact on health of sucrose and HFCS appears to be similar.) Johnson explained to me that although glucose is metabolized by cells all through your body, fructose is processed primarily in the liver. If you eat too much in quickly digested forms like soft drinks and candy, your liver breaks down the fructose and produces fats called triglycerides.

Some of these fats stay in the liver, which over long exposure can turn fatty and dysfunctional. But a lot of the triglycerides are pushed out into the blood too. Over time, blood pressure goes up, and tissues become progressively more resistant to insulin. The pancreas responds by pouring out more insulin, trying to keep things in check. Eventually a condition known as metabolic syndrome kicks in, characterized by obesity, especially around the waist; high blood pressure; and other metabolic changes that, if not checked, can lead to type 2 diabetes, with a heightened danger of heart attack thrown in for good measure. As much as a third of the American adult population could meet the criteria for metabolic syndrome set by the National Institutes of Health.

Recently the American Heart Association added its voice to the warnings against too much added sugar in the diet. But its rationale is that sugar provides calories with no nutritional benefit. According to Johnson and his colleagues, this misses the point. Excessive sugar isn’t just empty calories; it’s toxic.

“It has nothing to do with its calories,” says endocrinologist Robert Lustig of the University of California, San Francisco. “Sugar is a poison by itself when consumed at high doses.”

Johnson summed up the conventional wisdom this way: Americans are fat because they eat too much and exercise too little. But they eat too much and exercise too little because they’re addicted to sugar, which not only makes them fatter but, after the initial sugar rush, also saps their energy, beaching them on the couch. “The reason you’re watching TV is not because TV is so good,” he said, “but because you have no energy to exercise, because you’re eating too much sugar.”

The solution? Stop eating so much sugar. When people cut back, many of the ill effects disappear. The trouble is, in today’s world it’s extremely difficult to avoid sugar, which is one reason for the spike in consumption. Manufacturers use sugar to replace taste in foods bled of fat so that they seem more healthful, such as fat-free baked goods, which often contain large quantities of added sugar.

It’s a worst-case scenario: You sicken unto death not by eating foods you love, but by eating foods you hate—because you don’t want to sicken unto death.

In the Beginning Was the Fruit
If sugar is so bad for us, why do we crave it? The short answer is that an injection of sugar into the bloodstream stimulates the same pleasure centers of the brain that respond to heroin and cocaine. All tasty foods do this to some extent—that’s why they’re tasty!—but sugar has a sharply pronounced effect. In this sense it is literally an addictive drug.

This raises the question, however, of why our brains would evolve to respond pleasurably to a potentially toxic compound. The answer, Johnson told me, lies deep in our simian past, when a craving for fructose would be just the thing our ancestors needed to survive.

I paraphrase Johnson in a voice borrowed from the fables, for what are even the best theories, if not the old stories told again in the language of science? Some 22 million years ago, so far back it might as well be the beginning, apes filled the canopy of the African rain forest. They survived on the fruit of the trees, sweet with natural sugar, which they ate year-round—a summer without end.

One day, perhaps five million years later, a cold wind blew through this Eden. The seas receded, the ice caps expanded. A spit of land emerged from the tides, a bridge that a few adventurous apes followed out of Africa. Nomads, wanderers, they settled in the rain forests that blanketed Eurasia. But the cooling continued, replacing tropical groves of fruit with deciduous forests, where the leaves flame in autumn, then die. A time of famine followed. The woods filled with starving apes. “At some point a mutation occurred in one of those apes,” Johnson explained. It made that ape a wildly efficient processor of fructose. Even small amounts were stored as fat, a huge survival advantage in months when winter lay upon the land and food was scarce.

Then one day that ape, with its mutant gene and healthy craving for rare, precious fruit sugar, returned to its home in Africa and begot the apes we see today, including the one that has spread its sugar-loving progeny across the globe. “The mutation was such a powerful survival factor that only animals that had it survived,” Johnson said, “so today all apes have that mutation, including humans. It got our ancestors through the lean years. But when sugar hit the West in a big way, we had a big problem. Our world is flooded with fructose, but our bodies have evolved to get by on very, very little of it.”

It’s a great irony: The very thing that saved us could kill us in the end.

The Healthy Chef
Though just 11, Nick Scurlock is a perfect stand-in for the average American in the age of sugar. Hyperefficient at turning to fat the fructose the adman and candy clerk pump into his liver at a low, low price. One hundred thirty-five pounds in fifth grade, in love with the sweet poison endangering his life. Sitting in the lunchroom, he smiled and asked, “Why are the good things so bad for you?”

But this story is less about temptation than about power. At its best, the school can help kids make better decisions. A few years ago Pop-Tarts and pizza were served at Kirkpatrick. Now, across the district, menus have improved. The school has a garden that grows food for the community, a walking track for students and the public, and a new playground.

In a sense the struggle in Clarksdale is just another front in the continuing battle between the sugar barons and the cane cutters. “It’s a tragedy that hits the poor much harder than it does the rich,” Johnson told me. “If you’re wealthy and want to have fun, you go on vacation, travel to Hawaii, treat yourself to things. But if you’re poor and want to celebrate, you go down to the corner and buy an ice-cream cake.”

When I asked Nick what he wanted to be when he grew up, he said, “A chef.” Then he thought a moment, looked at his mom, and corrected himself. “A healthy chef,” he said.

Consuming too much sugar can increase the risk of premature death from heart disease, a finding that is fuelling calls for the Canadian and U.S. governments to offer dietary limits on sugar.

For an adult consuming 2,000 calories a day, drinking the equivalent of a bottle of pop sold in vending machines would exceed the level that a new U.S. study suggests raises the risk of death from cardiovascular disease (CVD).

“A higher percentage of calories from added sugar is associated with significantly increased risk of CVD mortality,” lead author Quanhe Yang of the U.S. Centers of Disease Control and Prevention in Atlanta and co-authors conclude in this week’s issue of the journal JAMA Internal Medicine.

The researchers analyzed national health and diet surveys between 1988 and 2010 of more than 30,000 Americans with an average age of 44. They found the fatal heart risk became elevated once added sugar intake surpassed 15 per cent of total calories.

“Too much sugar does not just make us fat; it can also make us sick,” said Laura Schmidt, a health policy specialist at the University of California, San Francisco, who wrote a commentary accompanying the study.

Previously, sugar used in processed or prepared foods, such as sugar-sweetened beverages, dairy desserts, candy, ready-to-eat cereals and yeast breads, has been linked to increased risks for non-fatal heart problems and with obesity. Naturally occurring sugars in fruit aren’t included.

Sugar is hugely important to the trillion-dollar processed food industry, said Michael Moss, a journalist in New York and author of the book, Salt Sugar Fat.

“They’re a very powerful lobby,” Moss said in an interview Tuesday.

“It’s very frustrating for consumers, especially when you go in and buy a product, look at the label and there’s a blank spot next to sugar. There is no government recommendation on how much sugar you should be capping yourself on and consuming in a day.”

The Canadian and U.S. governments don’t provide dietary limits for added sugar and there isn’t a consensus on how much is too much.

“What we really need as Canadians is more information,” said Dr. Yoni Freedhoff, an obesity doctor in Ottawa. “We need food labels that don’t allow for sugar synonyms and actually list the amount of added sugar there.”

To get a sense of sugar amounts, Freedhoff suggests that consumers take the number of grams of sugar on a package and divide by four to get the number of teaspoons.

Yang’s findings add to a growing body of rigorous studies that demonstrate added sugar “is not as benign as once presumed,” Schmidt said.

“Proponents of sugar taxes and sugar controls have a new arrow in their quiver and it’s this linkage to deadly heart disease,” Moss said. “That’s a very powerful tool in the hands of policymakers.”

Schmidt notes that the American Heart Association recommends no more than 25 grams a day or six teaspoons of sugar for women (five per cent of a 2,000-calorie a day diet) and 38 grams or nine teaspoons a day for men (7.5 per cent of daily calories).

In 2005, a panel at the Institute of Medicine, which advises the Canadian and U.S. governments, recommended added sugar make up less than 25 per cent of total calories. The World Health Organization (WHO) recommends less than 10 per cent.

Expert committees from the Institute of Medicine have concluded there’s no evidence of harm attributed to current sugar consumption levels, the Canadian Sugar Institute said in a statement to CBC News.

A spokeswoman for the trade group said Canadian sugar intakes are about 11 per cent of total calories. “There is no magic number because our age, gender and activity levels are all different.”

In the study, 831 people died from heart disease during the 15-year followup. The researchers took
other factors that contribute to heart problems, including smoking, inactivity and excess weight into account

Trans Fat in Animal Fat

February 27, 2014 by Michael Greg

Trans fats are bad. They may increase one’s risks of heart disease, sudden death, diabetes—and perhaps even aggression. Trans fat intake has been associated with overt aggressive behavior, impatience, and irritability.

Trans fats are basically found in only one place in nature: animal fat. The food industry, however, found a way to synthetically create these toxic fats by hardening vegetable oil in a process called hydrogenation, which rearranges their atoms to make them behave more like animal fats.

Although most of America’s trans fat intake has traditionally come from processed foods containing partially-hydrogenated oils, a fifth of the trans fats in the American diet used to come from animal products—1.2 grams out of the 5.8 total consumed daily. Now that trans fat labeling has been mandated, however, and places like New York City have banned the use of partially hydrogenated oils, the intake of industrial-produced trans fat is down to about 1.3, so about 50 percent of America’s trans fats come now from animal products.

Which foods naturally have significant amounts of trans fat? According to the official USDA nutrient database, cheese, milk, yogurt, burgers, chicken fat, turkey meat, bologna, and hot dogs contain about 1 to 5 percent trans fats (see the USDA chart inTrans Fat In Meat And Dairy). There are also tiny amounts of trans fats in non-hydrogenated vegetable oils due to steam deodorization or stripping during the refining process.

Is getting a few percent trans fats a problem, though? The most prestigious scientific body in the United States, the National Academies of Science (NAS), concluded that the only safe intake of trans fats is zero. In their report condemning trans fats, they couldn’t even assign a Tolerable Upper Daily Limit of intake because “any incremental increase in trans fatty acid intake increases coronary heart disease risk.” There may also be no safe intake of dietary cholesterol, which underscores the importance of reducing animal product consumption. See my video Trans Fat, Saturated Fat, and Cholesterol: Tolerable Upper Intake of Zero.

There’s been controversy, though, as to whether the trans fats naturally found in animal products are as bad as the synthetic fats in partially hydrogenated junk food. The lateststudy supports the notion that trans fat intake, irrespective of source—animal or industrial—increases cardiovascular disease risk, especially, it appears, in women.

“Because trans fats are unavoidable on ordinary, non-vegan diets, getting down to zero percent trans fats would require significant changes in patterns of dietary intake,” reads the NAS report. One of the authors, the Director of Harvard’s Cardiovascular Epidemiology Program, famously explained why—despite this—they didn’t recommend a vegan diet: “We can’t tell people to stop eating all meat and all dairy products,” he said. “Well, we could tell people to become vegetarians,” he added. “If we were truly basing this only on science, we would, but it is a bit extreme.”

Wouldn’t want scientists basing anything on science now would we?

“Nevertheless,” the report concludes, “it is recommended that trans fatty acid consumption be as low as possible while consuming a nutritionally adequate diet.”

Even if you eat vegan, though, there’s a loophole in labeling regulations that allows foods with a trans fats content of less than 0.5 grams per serving to be listed as having—you guessed it—zero grams of trans fat. This labeling is misguiding the public by allowing foods to be labeled as ”trans fat free” when they are, in fact, not. So to avoid all trans fats, avoid meat and dairy, refined oils, and anything that says partially hydrogenated in the ingredients list, regardless of what it says on the Nutrition Facts label.
