EWG says kids’ cereals have too much sugar

The Environmental Working Group (EWG) is getting interested in childhood obesity.  It released a report on sugars in kids’ breakfast cereals.

The report shows—no surprise—that kids’ cereals are really cookies in disguise, typically 40% -50% sugars by weight.   Kellogg’s Honey Smacks topped the list at 55%.

Michele Simon’s analysis of the report notes that these levels don’t even meet Kellogg’s commitment to responsible marketing, a pledge to “apply science-based Kellogg Global Nutrient Criteria to all products currently marketed to children.”

I’ve been reading reports like this since the 1970s when Center for Science in the Public Interest published them at regular intervals.  Not much has changed.

Courtesy of Kellogg, I have a collection of copies of Froot Loop boxes dating back to the year in which this cereal was first introduced.  I thought it would be interesting to check the sugar content.

Froot Loops, Sugar content, grams per ounce

YEAR GRAMS SUGARS PER OUNCE LABEL
1963-71 Lists calories: range 110-114
1972-75 Lists carbohydrate, not sugars
1976-78 14 Lists sucrose and other sugars
1979-92 13
1993-95 14 Nutrition Facts: sugars
1996-2006 15
2007 13
2008-11 12

In 2005, Kellogg tried a version with 1/3 the sugar—10 grams—but it didn’t sell and quickly disappeared.

Companies are trying to reduce the sugars by a little, but this seems to be the best they can do.  It’s not enough.

As the EWG press release explains, some cereals are better than others.   It notes that I recommend:

  • Cereals with a short ingredient list (of additives other than vitamins and minerals).
  • Cereals high in fiber.
  • Cereals with little or no added sugars (added sugars are ingredients such as honey, molasses, fruit juice concentrate, brown sugar, corn sweetener, sucrose, lactose, glucose, high-fructose corn syrup and malt syrup).
  • Even better, try fresh fruit and homemade oatmeal.

Sugar vs. HFCS, continued

The increasingly absurd fight between the Sugar Association and the Corn Refiners Association over what to call High Fructose Corn Syrup (HFCS) seems never to end.

Trade associations representing growers of sugar cane and sugar beets (sucrose–the white stuff on the table) have gone to court to charge that corporate members of the Corn Refiners Association (HFCS) are behind a “conspiracy” deliberately designed to “deceive the public.”  Why?  Because—in an equally absurd move—they want to change the name of HFCS to corn sugar. 

The sucrose-growers lawsuit argues Corn Refiners conspired to engage in false advertising as part of a $50 million campaign to promote HFCS by changing its name to “corn sugar,” thereby implying that HFCS is equivalent to “real” sugar from cane and beet plants.

Oh please.  Sucrose is glucose and fructose linked together.  HFCS is glucose and fructose separated.  Both are sugars (note: plural).  Sucrose is extracted from sugar beets and cane in a series of boiling, extracting, and cleaning steps.  HFCS does the same from corn, but uses one more enzyme so is somewhat less “natural,” but so what?

Both are sugars and empty calories, and everyone would be better off eating less of both.

What’s really at issue here is the encroachment of HFCS into sucrose territory.  Americans used to eat much more sucrose than HFCS.  Now we consume about 60 pounds of each of them a year—way too much of either.

My opinion: the name change is frivolous and so is the lawsuit. 

Both are a waste of time and distract from the real message: eat less sugar(s).

Sugar 1, HFCS 0, at least for the moment

The public relations firm for the Sugar Association, Levick Strategic Communications, sent me a press release celebrating the victory of sugar producers against corn refiners over the question of whether high fructose corn syrup (HFCS) can be renamed “corn sugar.”

A federal judge ruled that the case brought by the Sugar Association against the Corn Refiners can proceed to trial. If you want the details, see the  judge’s “order denying in part and granting in part defendents’ motion to dismiss”, and “order granting defendents’ motion to strike.”

I cannot even begin to tell you how funny I think all this is.

The Sugar Association represents growers of sugar beets and cane.  They produce table sugar—sucrose—a double sugar composed of glucose and fructose linked together.  In the body, sucrose is quickly split to glucose and fructose.

The Corn Refiners represent processors of corn (obviously).  They produce HFCS, a syrup made of glucose and fructose.

From a biological standpoint, glucose and fructose are the same no matter where they come from.  Biochemically, sucrose, glucose, and fructose are all sugars.

HFCS used to be a lot cheaper than sucrose, but what with all the corn used for ethanol, the price gap has narrowed.  As a result, and because HFCS has gotten a bad reputation, companies are dropping it in favor of sucrose.  The Corn Refiners are upset about that and think a name change would help.

The Sugar Association thinks it’s just great that HFCS has a bad reputation and does not want table sugar to be confused with corn sugar.

Both of these trade associations are acting totally in self-interest.  Neither cares at all about public health.  The lawsuit is entirely about corporate profits, not public welfare.

The Sugar Association is famous for protecting a system of quotas and tariffs that transfers money from American consumers to the coffers of sugar producers.  Its aggressive actions in its own self interest are legendary (see, for example, its threatening letter to me when Food Politics came out—this and my reply are posted at the end of the About section).

And I’ve written previously about the Corn Refiners’ consistently bad self-interested behavior.

Both trade associations behave with appalling disregard for the public.

In this case, the public interest is clear: everyone would be healthier eating less table sugar and HFCS.

Sugar politics in action: Sugar sues HFCS

Philip Brasher of the Des Moines Register reports: the Western Sugar Cooperative has just filed suit against the Corn Refiners and corn processors to stop them for falsely advertising HFCS as “corn sugar.”

Oh please.  Western Sugar is trying to claim that HFCS is not sugar, when it most definitely is.  To sugar associations, which represent cane and beet producers, sugar means sucrose (the white stuff on the table).

When the Sugar Association threatened to sue me for saying that soft drinks had sugar and nothing else (when they also contained HFCS), I patiently explained the biochemistry.  If you would like to read what they said, I’ve posted the threatening letter and my response at the bottom of this link. Here’s the biochemistry:

  • Sucrose: a double sugar of 50% glucose and 50% fructose linked together
  • HFCS: a syrup of about 45% glucose and 55% fructose, separated

The 5% differences are biologically insignificant and the body can’t tell them apart.

I never heard from the Sugar Association again, but I try to to remember to say sugars, plural.

Whether the FDA should allow the defendants to change the name of HFCS to Corn Sugar is a matter of some debate (see previous posts and comments on them).  The FDA will make its decision in due course.

In the meantime, this lawsuit is about marketing competition among sources of sugars (plural).  It has nothing to do with health.

A quick Q and A: sugars and fats

I wish I could answer all of the questions that come into Feedback or Comments, but I cannot except occasionally.  It’s a rainy day in New York and today seems to be one of those occasions.

Q: Does the caloric value of a food change when it’s cooked?  In his latest book, “Catching Fire: How Cooking Made us Human,” Harvard Primatologist Richard Wrangham argues that cooking foods changes the available nutrient content and actually raises the available calories.

A:  The rules of physical chemistry tell us that matter cannot be destroyed or created so the number of calories available in a food does not change with temperature.  What can change is our ability to use (digest, absorb) the calories that are there as well as our desire to eat the foods.  Cooking makes the calories in potato starch more available, for example, but has hardly any effect on the calories in meat.  Both, in my opinion at least, taste better cooked.    But cooked or not, the calorie differences will be small and unlikely to account significantly for weight change.

The nutrient situation is also complicated.  Cooking destroys some nutrients (vitamin C is a good example) but makes others more available (beta-carotene).  This is another reason why nutritionists are always advising variety in food intake.  Variety applies to cooked and raw, as well.

Q.  Can you please explain what benefits, if any, there are in using a “natural” sweetener, e.g. agave, over regular sugar?  Are there any differences in terms of glucose/fructose makeup?

A.  Agave is more expensive so you probably won’t use as much of it.  Beyond that, it is higher in fructose than table sugar or honey.  This is because agave contains inulin, a polymer of fructose, which must be hydrolyzed (broken down by heat or enzymes) to fructose to make the sweetener.  It’s a processed sweetener requiring one hydrolysis step, requiring more processing than honey and less than high fructose corn syrup.  It has the same number of calories as any other sugar, about 4 per gram or 16 per teaspoon.

Q.  Also, you’ve written on a prior blog that fructose is “preferentially” metabolized into fat by the body.  Can you explain in more detail what that means?

A.  More and more evidence suggests that high amounts of fructose in the diet are not good for health.  Fructose occurs naturally in fruit and nobody worries about that because fruits don’t contain all that much and the sugar is accompanies by vitamins, minerals, and fiber that are well worth eating.  Honey, table sugar, and high fructose corn syrup (a misnomer) are about 50% each glucose and fructose.  Glucose and fructose are metabolized differently and some investigators believe that excessive amounts of fructose stress metabolism in ways that encourage fat deposition.  Eating a lot of sugars of any kind is not a great idea, which is why there are so many concerns about soft drinks these days.

Q.  I would appreciate some comments about the “Meta-analysis of prospective cohort studies evaluating the association of saturated fat with cardiovascular disease.

A.  The study concludes:  

A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD [coronary heart disease] or CVD [cardiovascular disease]. More data are needed to elucidate whether CVD risks are likely to be influenced by the specific nutrients used to replace saturated fat.

This is a review of previous epidemiological studies (not clinical trials).  These fail to find a correlation between consumption of saturated fat and heart disease.  This could be because there is no correlation or there is one but they can’t find it.  My interpretation: even if there is one, it is likely to be small.

I am increasingly convinced that studies of single nutrients – sugar, fructose, saturated fat, or even omega-3s – will give complicated results when removed from their dietary context.  People who eat foods containing a lot of sugars or animal fats eat and behave differently than people who do not, but not so differently that health differences will show up in the kinds of studies scientists are currently able to do.

Keep in mind: nutrition science is exceedingly difficult to do because there are so many factors in foods that affect health and so many behavioral, economic, and social factors that affect what people eat.

All of this is why I find nutrition so interesting but I can understand why others might find it frustrating.

How will the sugar policy crisis shake out?

My Sunday (September 20) column in the San Francisco Chronicle deals with the sugar “crisis” I discussed here a few weeks ago:

Q: I saw you on “The Colbert Report” (Aug. 19) talking about sugar policy. Explain, please. I don’t understand why sugar policy is a topic for Comedy Central.

A: Neither did I until I saw Stephen Colbert douse himself with 5 pounds of sugar over the impending “crisis.” We have a sugar crisis? According to processed food manufacturers, we are about to run out of sugar. Horrors!

Earlier in August, Kraft and other food processors asked the U.S. Department of Agriculture to raise the quota on sugar imports. Sugar availability, they complained, is the lowest in years and it’s the USDA’s fault.

The USDA firmly controls amounts of sugar (sucrose) produced by American cane and beet growers through quotas. It even more firmly controls sugar imported from other sugar-growing countries through quotas and tariffs. And as corn is increasingly diverted to biofuels, less high-fructose corn syrup (HFCS) is around to make up the shortfall.

Should we worry?

The shortage is no crisis. At worst, it is temporary and will end as soon as the 2009 harvest is in. But processed food makers are right about one thing: Sugar is the most absurdly protected agricultural commodity in America.

For decades, no matter what it cost on the world market, quotas and tariffs ensured that Americans paid two or three times as much for sugar. High sugar prices cost American consumers about $3 billion a year. But because this works out “only” to about $10 per year per capita, nobody much cared.

If you think of $10 as trivial, you won’t give sugar protectionism another thought. But if you look at this system as an unnecessary transfer of $3 billion a year from 350 million Americans to a few thousand sugar growers and processors, you can understand why sugar policy is ripe for satire.

Here’s how the system works:

Quotas allow U.S. producers to grow only specified amounts of sugar cane and sugar beets each year, for which the USDA guarantees a higher-than-market price. Beets get 55 percent of the quota; cane gets 45 percent. The quotas are fixed. If you want to grow sugar beets in your backyard and sell the sugar to USDA at the favorable support price, too bad for you. You only get a quota if you already have a quota.

As for tariffs, the 2008 Farm Bill requires 85 percent of total sugar in the United States to be produced domestically, and allows only 15 percent to be imported. That 15 percent is distributed through quotas awarded to about 20 countries.

Above and beyond the quotas, imported sugar is subject to high tariffs. Mexico is an exception. Under NAFTA, Mexico gets to sell us as much sugar as it wants at the favored price. However, few countries in Africa hold quotas. What if you are an African cane-growing country and want the high quota price for your sugar? Not a chance.

Imports are never supposed to top 15 percent, so the USDA can’t increase the percentage. But we participate in the World Trade Organization, which obligates us to take world market sugar. Oops. These policies don’t match. Processed food makers must think the contradictions will allow the USDA to let in more sugar. Maybe, but the legalities are not yet decided.

Mind you, sugar producers and processors love this system. They argue that it keeps jobs in rural America and eliminates dependence on foreign sugar imports. To make sure nobody scrutinizes the system too carefully, they formed cooperatives to avoid antitrust laws.

Sugar producers are among the most generous and equal-opportunity contributors to congressional election campaigns, giving to both Democrats and Republicans. For decades, administrations of both parties have tried to end sugar supports. No such luck.

A shift’s brewing

Policies may change, because the gap between the prices for domestic and world market sugar – and for high fructose corn syrup – has narrowed recently. Sugar is now at war with HFCS. As HFCS is increasingly known as a key junk food ingredient, manufacturers are rushing to replace it with sucrose, which they can tout as “natural and unprocessed.”

Other sugar issues are also ripe for comedy. Most sugar beets are now genetically modified, leading many companies to avoid using beet sugar. In the South, sugar cane production pollutes the Everglades, which is costing billions of dollars to clean up. Investigative reporters are riveted by the feudalistic labor practices of sugar plantations.

And then there’s Cuba. Until the Castro revolution, that’s where we got most of our imported sugar. When relations improve, will Cuba get a sugar quota?

If sugar is responsible for any true crisis, it is because of its role as an ingredient in processed foods. Cheap sugar reduces the cost of candy and soft drinks. Cheap junk foods are highly profitable. Otherwise, our sugar policies make no sense in today’s global marketplace.

But we would be healthier eating less sugar, anyway. So here’s my solution to the non-crisis: Eat less sugar!

American Heart Association: Eat (a lot!) less sugar.

At last, the American Heart Association (AHA) has done something useful.  It advises eating less sugar.  Americans eat way too much, it says, a whopping 22 teaspoons a day on average.  Let’s work this out.  A teaspoon is 4 grams.  A gram is 4 calories.  So the 275 calories in that default 20-ounce soda you picked up from a vending machine come from nearly 17 teaspoons of sugar – close to the average right there.  If you have trouble maintaining weight, soft drinks are an obvious candidate for “eat less” advice.  Neither the Wall Street Journal (in which I am quoted) nor the New York Times say much about how soft drink manufacturers are reacting to this recommendation, but it isn’t hard to guess.

Here, for example, is what the industry-sponsored American Council on Science and Health (ACSH) has to say:

The study targets added sugars as the main culprit of dietary excess, but since “U.S. labels on packaged foods do not distinguish between naturally occurring or added sugars,” it is difficult to tell the difference. However, “our bodies can’t tell the difference either,” says ACSH’s Jeff Stier. “Natural and added sugars are nutritionally the same. Added sugar causes obesity as much as the orange juice promoted by the American Heart Association causes obesity [e-mail newsletter, August 25, 2009].

Smart Start

This is the first time the AHA has seriously weighed in on sugar.  I find this especially interesting because the AHA has a long history of endorsing sugary cereals (as I discuss in Food Politics and also in What to Eat).  In this example, the AHA’s endorsement is in the lower left corner.  This product has sugars of one kind or another listed 9 times in the ingredient list.

The AHA gets paid for such endorsements.  Let’s hope the new recommendation encourages the AHA to stop doing this.

Update August 27: I really don’t know what to say about the ACSH’s Jeff Stier.  he is acting more like the Center for Consumer Freedom’s Rick Berman every day.   Today’s e-mail newsletter from ACSH contains this statement:

In her blog in The Atlantic, NYU Professor of Nutrition Dr. Marion Nestle has fallen into the habit of suggesting that ACSH is incapable of objective analysis of public health concerns because we are, in her distorted view, “thoroughly industry-sponsored.”

ACSH’s Jeff Stier wrote to her editors: “Like many of the country’s top non-profits, Dr. Nestle’s NYU included, we accept corporate donations, with no strings attached. But we also receive significant support from individuals and foundations. Her misleading description of us suggests that we represent industry. We do not. We are advised by some of the nation’s leading scientists and represent consumers.

“By way of this email, I ask for a conspicuous and fair correction. We are happy to engage on the issues Dr. Nestle writes about, but her attacks on us are below someone of her stature. We’d prefer an informed and enlightening discussion of the issues, not underhanded and unfounded attacks on credibility.”

“Apparently, Dr. Nestle believes that your opinions are irrelevant, since they diverge from her ideological agenda,” says Stier. “We represent you, consumers, who want science rather than ideology informing public health decisionmaking. Does she really think that consumers are so monolithic that they either agree with her or are put up to it by some sinister entity?”

Readers: Does anyone know what is going on with this group?  It sounds so much like the Center for Consumer Freedom that I can’t help but wonder.

Colbert Report: The sugar crisis!

Colbert Report, August 19: I was interviewed on the Colbert Report about sugar policy, of all things.  U.S. sugar policy is so absurd that I did not think it could be satirized, but Colbert managed just fine.  Here’s what I would have said if I hadn’t been completely disconcerted by his dousing himself with five pounds of sugar:

The sugar “crisis”: On August 5, several groups representing makers of processed foods wrote a letter asking the USDA to raise the quota on imported sugar because stocks are lower than they have been in years.  Why?  Because domestic sugar production is thoroughly governed by quotas, imported sugar is thoroughly controlled by quotas and tariffs, and high fructose corn syrup (HFCS) is increasingly diverted to ethanol.  Got that?

Reminder about definitions: “Sugar” usually refers just to sucrose made from sugar cane and sugar beets; it is glucose and fructose stuck together.  The other major sweetener is high fructose corn syrup (HFCS).  It is also made of glucose and fructose, but separated.   Sucrose and HFCS work the same way in the body and are hardly distinguishable physiologically.   For the purposes of this discussion, I use sugar to refer to the sweetener refined from sugar beets and sugar cane, and HFCS for the sweetener made from corn.

Sugar protection policies: Even though it amounts to only 1% of agricultural production, U.S. sugar is the single most heavily protected agricultural commodity.  No matter what the price on the world market, U.S. sugar producers and processors get paid a high price.  Historically, this price has been two to three times higher than world market prices.   Although this has for decades cost American consumers $2 billion to $3 billion a year in higher sugar prices, nobody much noticed because it “only” amounted to about $10 per year per person over and above what you would pay for sugar anyway.  Today, the gap between domestic and world market prices has gotten much smaller, mainly because there isn’t as much HFCS around (more on this later).

Quotas and tariffs: These are amazing, really.  U.S. producers are allowed to grow a certain amount of cane and beets each year for which they are guaranteed a price set by USDA.    Beets get 55% of the total quota allotment and cane gets 45%. This works like a closed shop.  If you want to start growing beets or cane for domestic sugar production, too bad.  Catch 22: You only get to have a quota if you already have a quota.  As for tariffs:  The 2008 Farm Bill says that 85% of total sugar in the U.S. must be produced domestically, and only 15% can be imported.  That 15% comes in through quotas distributed among about 20 countries.   Any other sugar they want to send us is subject to high tariffs, except from Mexico.  Under NAFTA, Mexico can export as much sugar to us as it wants to at the favored price.  But imported sugar is never supposed to exceed 15%.

International issues: Our agreement with the World Trade Organization (Uruguay Round) says we have to take a certain amount of world market sugar.  But the 2008 Farm Bill restricts imports.  Oops.  The contradictions in these policies still have to be resolved.  The processed food people think the USDA can raise the percentage.  Can it?  Hmmm.  We don’t know this yet.

Who benefits: A few thousand beet producers in about 15 states and a few hundred cane producers, and the sugar processors.  They get paid amounts that are higher than world market prices.   The countries that have sugar quotas also get higher prices for their sugar quotas.  Producers of sugar cane and beets love this system.   Florida cane producers defend it this way: “U.S. sugar policy ensures that jobs in rural America are not sent overseas, and that American consumers are not held captive by unreliable foreign suppliers of subsidized sugar.”  Like American-owned sugar plantations in the Dominican Republic, for example?

Who loses: According to the Government Accountability Office, everyone in America pays higher prices for sugar than we need to.  This amounts to a transfer of wealth from 350 million of us to a few thousand sugar producers and processors.   International sugar-producing countries that do not have quotas, those in Africa, for example, are also out of luck.

How this happened: The system started out in the Great Depression with the best of intentions.  Despite endless attempts to get rid of sugar supports and let prices fluctuate according to the world market, Congress continues this elaborate and expensive system to protect sugar producers and processors.  These groups have banded together in cooperatives so they avoid anti-trust laws.   Even the New York Times thinks we should get rid of sugar protections.  These groups, of course, are among the most generous and powerful contributors to congressional election campaigns.  Even more, they are equal opportunity contributors: they give to both Democrats and Republicans.  The Fanjul family in Florida is especially influential.  In the best known example, Mr. Fanjul was able to get President Bill Clinton to take his call on a federal holiday when Clinton was in the midst of a tryst with Monica Lewinsky (source: the Starr report).

What about HFCS: The public now puts HFCS in the same category as trans fats: poison (it’s not; it’s just sugars).   In response, makers of processed foods and beverages are starting to replace it with cane and beet sugar.   As explained in the current Advertising Age, sugar is now at war with HFCS.  HFCS used to be a lot cheaper than sugar, but its cost has gone up as more of it is used for ethanol.  Supply is down; costs are up.

Other issues: As if all this wasn’t complicated enough, sugar beets are largely genetically modified, leading more than 70 companies to say they won’t use that sugar.  Sugar cane production in the Southern states pollutes the Everglades, leading to billions of dollars in clean up costs.  And the labor practices of sugar cane plantations have long been the subject of much investigative reporting.  And what about relations with Cuba?  Until the Castro revolution, we got nearly all of our imported sugar from our Caribbean neighbor.  If relations with Cuba improve, will that country have a quota?

So what’s really going on? Food processors want cheap ingredients.   Cheap sugar makes for relatively cheap junk foods and high profits for manufacturers.  Current sugar policies make no sense in today’s global marketplace and we all ought to be eating less sugar anyway.  On average, we have about 70 pounds of sugar and another 70 of HFCS available per year for every man, woman, and child in the country along with a few pounds of other caloric sweeteners to boot.  That’s close to half a pound of sugary calories per day.   Less of all of them would be better, no? 

A final happy thought:  Maybe the processed food makers’ request – which is entirely self-interested – might lead to improvements in U.S. farm policy as well as relations with sugar-producing countries in the Caribbean and Africa.
