Gatorade: the new health food?

On April 20, I received a letter from a Gatorade PR person commenting on one of my posts reposted at the Atlantic Health/Food section.

After reading the letter, I searched my posts for references to Gatorade but can’t find anything specific other than my reporting the more than $100 million a year Pepsi spends to advertise this product.

So I’m guessing the letter must be referring to my comments about sports drinks in general:

Hi Marion –

I recently read your article in The Atlantic and would like to make sure you have the most current information. Your article criticizes sports drinks, advising against them because the sugars and carbs will make you fat. It also discusses the main sweetener in most sports drinks is high fructose corn syrup.

I would like to point out the carbohydrates and calories are functional in Gatorade, a sports drink, and are meant to provide fuel specifically for athletes.

The ingredients in Gatorade are backed by years of scientific research that support the need for carbohydrate sugars for fuel during training or competition and we only recommend Gatorade during the active occasion.

Also, high fructose corn syrup is not an ingredient in any Gatorade products.

For those looking for a lower-calorie sports beverage, Gatorade offers G2, which delivers the same amount of electrolytes as original Gatorade but with half the calories. Gatorade also recently introduced G Series FIT 02 Perform, which is designed for a fitness athlete and has 10 calories per 8oz serving.

Please let me know if you have any questions or need any additional information.

Best,

Katie Montiel, Gatorade Communications

I’m always happy to hear from interested readers.

And aren’t you glad to know that sugar is a functional (translation: “good-for-you”) ingredient in Gatorade?

Where are we on BPA?

BPA has become a classic example of how point of view influences decisions about low-dose chemicals in the food supply for which the science is uncertain.

If you are a believer in the “precautionary principle,” any suggestion of harm is enough to support banning BPA until it is proven safe.

European countries tend to subscribe to the precautionary principle.  Sweden, for example, has just banned BPA.

If, on the other hand, you believe that nothing should be banned until incontrovertibly demonstrated by science to cause harm, you won’t act against BPA until the evidence for harm is overwhelming.

That’s the FDA’s position.  Even though the FDA is troubled by the lack of better information about the safety of BPA, it recently denied a petition from the National Resources Defense Council to ban it (see FDA Law Blog for details).

Although FDA is not persuaded by the data and information in your petition to initiate rulemaking to revoke the food additive approvals for BPA, FDA will continue in its broader and more comprehensive review of emerging data and information on BPA.

This tells me that the FDA is plenty worried about BPA but will not (or cannot) act without more evidence.

The FDA’s main page on BPA says:

At this interim stage, FDA shares the perspective of the National Toxicology Program that recent studies provide reason for some concern about the potential effects of BPA on the brain, behavior, and prostate gland of fetuses, infants and children.

Its page on the chemical nature of BPA explains that because it is used to make a hard, clear plastic used for reusable water bottles (including baby bottles) and epoxy resins that line the inside of metal-based food and beverage cans, BPA is extremely widespread in the food supply.

The FDA first approved BPA in the early 1960s. In 2008, the agency released a draft report judging BPA safe in food contact materials. In 2010 and again on March 30, 2012, the FDA issued an interim update on BPA.

These reports say that the FDA considers BPA safe at current levels of exposure, but also suggest that reducing exposure is a good idea.

Thus, the FDA’s consumer page on BPA says

The Food and Drug Administration’s assessment is that the scientific evidence at this time does not suggest that the very low levels of human exposure to BPA through the diet are unsafe [note obfuscating double negative].

The agency has performed extensive research on BPA, has reviewed hundreds of other studies, and is continuing to address questions and potential concerns raised by certain studies [it must be desperate for answers].

FDA scientists have also recently determined that exposure to BPA through foods for infants is much less than had been previously believed and that the trace amounts of the chemical that enter the body, whether it’s an adult or a child, are rapidly metabolized and eliminated [if true, this should come as a huge relief].

FDA’s parent agency, the Department of Health and Human Services, offers advice for parents about BPA, reiterating its safety, but asking:

Q: Should I throw away baby bottles that contain BPA?

A: Parents should examine bottles and discard them if worn or scratched because scratches can both harbor germs and, in BPA-containing bottles, lead to greater release of BPA.  For those who want to use baby bottles and feeding cups not made with BPA, consumers should know that such products are now widely available in the U.S. market.

What all this means is that the FDA is sticking to—or has to stick to—a science-based position on BPA, but it is hedging bets by urging parents and the public to apply the precautionary principle and avoid BPA whenever possible.

This shifts the burden of protection against harm from the government to you.

Does this make sense?  I don’t think so.  You?

Books: thinking about food

Two thoughtful books about how to think about food:

Peter Kaminsky, Culinary Intelligence: The Art of Eating Healthy (And Really Well), Knopf, 2012.

I blurbed this one:

Peter Kaminsky’s rules for taking pounds off and keeping them off are based on a really good idea: flavor per calorie.  That works for him and should make dieting a pleasure.

His chapter titles get the tone and flavor: The fundamentals of flavor, the elements of taste; the joy of cooking.  And he offers a practical guide to restaurant dining.  Most useful.  He’s a good writer and the book is fun to read.

Barb Stuckey, Taste: What You’re Missing: The Passionate Eater’s Guide to Why Good Food Tastes Good, Free Press, 2012.

Stuckey is a professional food developer for whom understanding what makes for taste and flavor is essential.  This chatty and accessible book is a great introduction to how and what we taste, and why.  She ends it with a chapter on 15 ways to get more from every bite.  My favorite: “be adventurous, but patient.”

Nutritionist’s Notebook: Consuming Calories

On Tuesdays, I answer questions about nutrition for NYU’s student newspaper, the Washington Square News.  Yesterday’s was about when calories count.

Question: With finals approaching ,many students will be staying up very late. Is the time of day important in relation to when you are consuming most of your calories? What are some good late-night, study snack options for students?

Answer: Having just written a book about calories, they are much on my mind. Here is one take-home lesson from the book. If you look only at body weight, calories are the determining factor. If you eat more calories than you need, you gain weight no matter where the calories come from.

But if you care about health, the source of the calories is crucial. What can be confusing about this distinction is that eating a healthy diet — one with plenty of vegetables, fruits and grains and only occasional junk food — makes it much easier to balance calories.

The two results of what you eat — weight and health — are closely linked.

Does when you eat matter? From a strictly caloric standpoint, no. If you haven’t overeaten during the day, adding calories late at night should not be a problem.

But if you habitually add late-night calories to full meals during the day, you might find your weight creeping up. Some studies show that the more times a day people eat, the more calories they consume. But others find that consuming small amounts of food throughout the day helps people maintain weight. You need to figure out for yourself which pattern works best.

The only way to tell if you are eating the right amount of calories is to weigh yourself regularly. If your weight is going up, you might want to avoid adding calories in late-night snacks.

What’s a reasonable snack? Any real, relatively unprocessed food is always a good choice: fruits, vegetables, nuts, yogurt, cheese, crackers, sandwiches, salads. Even pizza can do the trick if it’s thin crust and not overflowing with cheese.

Do We Need Better Advice About Eating Well? I Vote Yes.

The New York Times asked me, among others, to contribute to its  Room for Debate blog on the question of whether anyone could possibly need to hear one more word about what constitutes a healthful diet.  Here’s my two-cents’ worth:

Better Information and Better Options

Of course Americans need more information about eating well. Otherwise we wouldn’t have an obesity problem. In my daily teaching and contact with the public, I hear endless confusion about what to eat.

People are bombarded with conflicting advice, much of it from sources with a vested interest in selling particular foods, supplements or diet plans. Nutrition studies tend to focus on single nutrients, making their results difficult to apply to real diets. No wonder people have a hard time knowing what or whom to believe.

This is too bad, really. The basic principles of healthy eating could not be easier to understand: eat plenty of vegetables and fruits, balance calorie intake with expenditure, and don’t eat too much junk food.

If such principles seem hard to follow, it is surely because of how they affect the food industry. Balancing calorie intake often means eating less, but doing so is bad for business. Food companies must do everything they can to sell more food, not less.

So they make foods available everywhere — even in drug, book and clothing stores — and in very large portions. Few people can resist eating tasty food when it’s right in front of them. Large portions alone explain rising rates of obesity: they encourage people to eat more calories but to underestimate what they have eaten.

Healthy eating requires a food environment that makes it easier for everyone to make better choices. It also requires a food system that makes it cheaper to buy fruits and vegetables than less healthful foods, so everyone can afford to eat healthfully. Fix the farm bill!

The exceedingly strange world of federal crop insurance subsidies

According to an account in last week’s New York Times, the federal government could save about $1 billion a year by reducing the subsidies it pays to large farmers to cover much of the cost of their crop insurance.  Crop insurance subsidies are expected to cost $39 billion from 2012 to 2016, or about $7.8 billion a year.

The Times based this statement on a new report from the Government Accountability Office.  This report explains that the billion-a-year savings would occur if the government applied the same limits to subsidies for crop insurance as it applies to other farm support programs.

The report raised the prospect of the government’s capping the amount that farmers receive at $40,000 a year, much as the government caps payments in other farm programs. Any move to limit the subsidy, however, is likely to be opposed by rural lawmakers, who say the program provides a safety net for agriculture.

Get this:

Under the federal crop insurance program, farmers can buy insurance policies that cover poor yields, declines in prices or both. The insurance is obtained through private companies, but the federal government pays about 62 percent of the premiums, plus administrative expenses.

And that’s not all.  The Environmental Working Group says many of the crop insurers are foreign companies.

Twenty insurance companies in Bermuda, Japan, Switzerland, Australia, Canada and the U.S. were paid $7.1 billion in U.S. taxpayer funds from 2007 to 2011 to sell American farmers crop insurance policies, an Environmental Working Group analysis shows. The U.S. Department of Agriculture’s Risk Management Agency paid these companies for administrative and operating expenses for the federally subsidized crop insurance program.

We talked about crop insurance subsidies in the class on the farm bill that I taught at NYU last fall.   My class thought all of us should immediately go into the crop insurance business.  The government pays most of the premiums and administrative expenses and also covers most of the risk.  This is a really good deal for Big Ag and the lucky few insurance companies.

You find this difficult to believe?  Take a look at two of the readings for the course:

Shields DA.  Federal crop insurance: background and issues.  Congressional Research Service, December 13, 2010.

Insurance policies are sold and completely serviced through 16 approved private insurance companies. Independent insurance agents are paid sales commissions by the companies. The insurance companies’ losses are reinsured by USDA, and their administrative and operating costs are reimbursed by the federal government.

Smith VH.  Premium payments: why crop insurance costs too much.  American Enterprise Institute, 2011.

Since 2007, government subsidies for crop insurance have averaged about $5.6 billion per year, representing over one-third of total expenditures on income transfers and other government payments for programs targeted directly to farmers.

However, about 58 percent of those expenditures have ended up in the hands of agricultural insurance companies and agricultural insurance agents.

In fact, since 2005, on average, the agricultural insurance industry has received $1.44 for every dollar farmers have received in crop insurance subsidies.

No wonder Big Ag wants crop insurance subsidies continued.

Will the 2012 farm bill fix this?  I’m not optimistic but will stay tuned.

Another Q and A on Why Calories Count

NYU did an interview for the Steinhardt School’s website:

Why did you write this book?

Calories are critical to the most important public health, social, and economic issues facing the world today. About a billion people in the world do not take in enough calories to maintain health and are hungry and malnourished and another billion or so take in so many that they are overweight or obese and have higher risks for chronic disease and disability. The food industry takes in more than a trillion dollars a year in the United States alone. The U.S. diet industry is worth about $60 billion a year. The public is demonstrably confused about the meaning of calories and their relationship to food intake and weight loss. We thought it would be useful to write a book that provided accessible information about calories in all of their dimensions—scientific, health, and political.

What is a calorie?

Calories measure energy to keep bodies warm, power essential body functions, move muscles, or get stored as fat.

Why are calories a problem?

You can’t see, taste, or smell them. The only way you can recognize them is by their effects on your waistline or on a scale. They are not easy to count accurately and the best way to measure them is to weigh yourself regularly.

What are some of the themes of the book?

If you want to understand calories, you need to know the difference between calories measured and estimated. Most studies of diet, health, and calorie balance depend on self reports of dietary intake and physical activity or educated guesses about the number of calories involved. Most diet studies rely on estimates. When it comes to anything about calories in food or in the body, you have to get used to working with imprecise numbers. That is why it works better to eat smaller portions than to try to count calories in food. Even small differences in the weight of food will throw calorie estimations off.

Politics? What’s political about calories?

As with everything else having to do with food and nutrition, many groups have a stake in how calories are marketed, perceived, labeled, and promoted. As we’ve already said, eating fewer calories is bad for business. Efforts to do something about obesity in adults and children focus on eating less or on eating better, meaning eating more fruits, vegetables, and grains but consuming less of sodas, fast food, snacks, and other highly profitable items. Such matters as soda taxes, listing calories on food labels or menu boards, or campaigns to promote smaller portions are all political responses to concerns about calorie consumption. Here’s one example: for years, consumer groups have pushed for calorie and nutrition labeling on alcoholic beverages, but the Treasury Department (not the FDA) regulates such things and responds to the wishes of the industry.

What are the most important conclusions of the book?

If you want to eat well and maintain a healthy weight in today’s food environment, we advise: First, get organized; get motivated, monitor your weight regularly, join a weight loss group. Then eat less, move more, eat better and get political; work to change the food environment to one that makes it easier to eat healthfully, support labeling laws, nutrition education, controlling advertising to children, agricultural policies that encourage consumption of fruits and vegetables and local food systems, and environments that encourage physical activity.

And for another view: My co-author, Dr. Malden Nesheim, did a Q and A on the book with Diets in Review.
