Ordinarily I find government plans of this type to be soporific but this one is especially well written and well thought out (with some caveats).

The report is a statement of FDA commitment to what it is going to do in the next four years in food areas that affect people and animals.  It includes many promises, among them this one of particular interest: 

Program Goal 4: Provide accurate and useful information so consumers can choose a healthier diet and reduce the risk of chronic disease and obesity

Objective 1. Update the Nutrition Facts label.

• Publish proposed rules updating the nutrition facts label and serving sizes [OK, but by when?].
• Publish final rules updating the nutrition facts label and serving sizes [Ditto].

Objective 2.  Implement menu and vending machine labeling regulations.

• Publish final menu and vending machine labeling regulations [OK, but by when?].
• Collaborate with states, localities and other partners to ensure high rates of compliance.

Objective 3.  Improve consumer access to and use of nutrition information.

• Explore front‐of‐pack nutrition labeling opportunities [Explore?  See comment below].
• Collaborate with public/private sector parties on nutrition education [Collaborate?  See comment below].
• Implement updated standards for the labeling of pet food including nutrition and ingredient information [How about a Pet Facts label for pet foods that someone might actually be able to understand?].
• Implement standards for animal feed ingredients.
• Publish final rule defining and permitting use of the term “gluten free” in the labeling of foods.

Goal-setting processes usually include dates by which the objectives are to be completed.  These do not, which suggests that the FDA can continue to delay action until 2016. 

I also do not understand what is meant by “Explore front‐of‐pack nutrition labeling opportunities.”  Explore?  The FDA has already sponsored two Institute of Medicine reports on front-of-pack labeling.  Does this mean the agency is ignoring them and intends further research?

And “Collaborate with public/private sector parties on nutrition education?”  What does the FDA have in mind for the content of such education?  You can bet that no collaborative campaign can focus on “don’t drink your calories.” 

FDA needs to deliver on these items, and sooner rather than later.  This year?  I’m not counting on it.

My Tuesday question from student readers of NYU’s Washington Square News:

Question: How can we determine our individual caloric, vitamin, carbohydrates, fats and other intake requirements per day based on our own individual weight, height and lifestyle?

Answer: You can’t. You will have to be satisfied with estimates based on measurements performed years ago on a small number of study subjects.

We require calories and nutrients — 40 to 50 separate substances that our bodies cannot make, we must get from food. Because these interact, studying one at a time gives results that may well be misleading.

Early nutrition scientists got “volunteers”— in quotes because study subjects often were prisoners — to consume diets depleted in vitamin C, for example. They waited until the subjects began to develop scurvy, a sign of vitamin C deficiency. Then they fed the subjects the smallest amount of vitamin C that would eliminate symptoms.

Because individuals vary in nutrient requirements, scientists used this data to estimate the range of nutrient intake that would meet the needs of practically everyone.

The Institute of Medicine compiles such data into Dietary Reference Intakes and presents the estimates by sex and age group. You can look up your requirements in DRI tables. DRIs account for the needs of 98 percent of the population. If your requirements are average, you will need less.

Few American adults show signs of nutrient deficiencies, but if you are worried about your own intake of nutrients, you can take a multivitamin supplement. Note, however, that we have no evidence to show supplements make healthy people healthier.

You can estimate calories by looking up everything you eat or drink in food composition tables, but it is easier to weigh yourself at regular intervals. If you are gaining weight, you are eating too many calories for your activity level.

With nutrition, it’s best to get comfortable with estimates and probabilities.

Fortunately, eating a healthy diet takes care of nutrients without your having to give them a thought. Eat your veggies!

A version of this article appeared in the Tuesday, May 1 print edition. Marion Nestle is a contributing columnist. Email her questions at dining@nyunews.com.

A question from a reader:

Q.  I was wondering if you could comment on the recent article in the New York Times which questions the link between food deserts and obesity.

A.  Sure.  Happy to.  The article talks about two recent studies finding no relationship between the types of foods children eat, what they weight, and the kinds of foods available within a mile and a half of their homes.

These finding seem counter-intuitive in light of current efforts to improve access to healthier foods in low-income communities.

Obesity is more common among the poor than among those who are better off.   Poor people must be eating more calories than they expend in physical activity.

Eating more calories means eating more of foods high in calories, especially fast food, snacks, and sodas.  Kids who are heavier have been found to eat more of those foods than those who are not.

I can think of several reasons why this might be the case:

• Access: healthier foods are less available
• Cost: healthier foods cost more
• Skills: healthier foods require preparation and cooking
• Equipment: cooking healthier foods requires kitchen facilities, pots, and pans
• Transportation: even if stores are available, they might be too far away to walk to
• Quality: even if stores sell fruits and vegetables, they might not be fresh
• Marketing: fast foods, snacks, and sodas are heavily marketed in low-income areas
• Peer pressure: eating high-calorie foods is considered the norm

I can think of ways we might try to improve any of these factors, but I’m guessing that cost is the critical factor for people with limited means.  The Department of Commerce reports that the indexed price of fresh fruits and vegetables has increased by 40% since 1980, whereas the indexed price of sodas has declined by about 30%.

Fast food, snacks, and sodas are cheap.  Fruits and vegetables are not.

Without access to healthful foods, people cannot eat healthfully.  But access alone cannot reverse obesity.

The real issue is poverty.  Unless we do something to reduce income inequality, and to make healthier foods more affordable, fixing the access problem is unlikely to produce measurable results on its own.

Posted from the World Public Health Association annual meeting, World Nutrition 2012, in Rio.

I am in Brazil at meetings of World Nutrition Rio 2012 but was deluged yesterday by links to a lengthy Reuters’ Special Report: How Washington went soft on childhood obesity.

In an e-mail, Reuters explains that its report is about how food and beverage companies dominate policymaking in Washington, doubled lobbying expenditures during the past three years, and defeated government proposals aimed at changing the nation’s diet.

• The White House, despite First Lady Michelle Obama’s child obesity campaign, kept silent as Congress killed a plan by four federal agencies to recommend reductions to sugar, salt and fat in food marketed to children.
• Corporate lobbying last year led Congress to declare pizza a vegetable to protect it from a nutritional overhaul in the school lunch program.
• The Center for Science in the Public Interest, widely regarded as the lead lobbying force for healthier food, spent about $70,000 lobbying– roughly what companies opposing stricter food guidelines spent every 13 hours.
• The food and beverage industry has a near-perfect record in political battle even while health authorities link unhealthy food to the child obesity epidemic.
• During the past two years, each of the 24 states and five cities that considered “soda taxes” has seen the efforts dropped or defeated.

Reuters Investigates also has a video about how the food industry fought back when the White House sought healthier school lunches and Congress directed federal agencies to set nutrition standards.

Readers of this blog may recall my post last December fretting about the White House pullback, and the vigorous denial the next day by White House senior food policy advisor Sam Kass.

I attributed White House caution to the upcoming election.  Reuters does too, apparently, and so does the New York Times. 

If the First Lady is to make real progress on Let’s Move, she needs all the support she can get.  This might be a good time to send a note to the White House strongly encouraging more vigorous action on methods to address childhood obesity.

Politics does indeed make strange bedfellows. 

The American Enterprise Institute, a conservative (to say the least) think tank, has just issued a report on reforming the farm bill to ensure a safer food system.  Its stunning conclusion:

More feasibly, in the short to medium term, changes in food safety regulation should aim at correcting inconsistencies or loopholes that exist in US food safety laws.

For example, policymakers could merge the FSIS and the FDA to allow for a better allocation of resources and exploit potential return to scales.

Standardizing states’ detection systems for food-borne illnesses and collecting better data about the incidence of food-borne illnesses would make firms more accountable and help construct better food safety policies.

Merge the food safety functions of USDA and FDA?  This, of course, is precisely what food safety advocates and the Government Accountability Office have been urging since the early 1990s. 

Now, maybe, it has a chance?

On April 22, the New York Times published an unusually lengthy account (front page plus three full pages) of how Walmart executives in Mexico bribed officials to allow the company to open stores in many locations in record time.

I was struck by the simplicity of the rationale for the illegal behavior (I’ve italicized the key points):

But The Times’s examination uncovered a prolonged struggle at the highest levels of Wal-Mart, a struggle that pitted the company’s much publicized commitment to the highest moral and ethical standards against its relentless pursuit of growth.

Under fire from labor critics, worried about press leaks and facing a sagging stock price, Wal-Mart’s leaders recognized that the allegations could have devastating consequences, documents and interviews show.

Wal-Mart de Mexico was the company’s brightest success story, pitched to investors as a model for future growth. (Today, one in five Wal-Mart stores is in Mexico.) Confronted with evidence of corruption in Mexico, top Wal-Mart executives focused more on damage control than on rooting out wrongdoing.

As I keep saying, Wall Street pressures on corporations not only to make profits, but to grow profits every quarter, are the root cause of much food company corruption and corner-cutting.

You have to feel sorry for the beef industry.  First pink slime, now a mad cow.

Here’s what we know about the latest mad cow scare (the USDA has a page devoted to mad cow disease, so does the FDA, and I wrote about it in my book, Safe Food: The Politics of Food Safety).

• Mad cow is the common name for bovine spongiform encephalopathy (BSE), a fatal disease caused by abnormal proteins (prions) in the brain and nervous system.
• The disease affected 37,311 cows in Great Britain in 1992.
• In 2011, there were only 29 cases worldwide.
• No human case has been seen in the U.S., except for one in a woman who moved here from England at the time.
• The affected cow found in California is only the fourth in the U.S. since the testing program started a decade ago.
• The USDA tests about 40,000 cows a year out of the 34 million slaughtered. 
• This one was evidently high risk.  It died and was sent to a rendering plant.  It either looked suspicious enough to be singled out for testing or was picked up on routine testing.
• When the test came back positive, authorities impounded the carcass.
• It never entered the food supply for either people or pets.
• How it got the disease in the first place is either unknown or undisclosed.  The most likely possibility is that the disease developed spontaneously (as it does occasionally in older cows).

According to the Wall Street Journal,

The disease was detected on a cow carcass taken in for rendering last Wednesday at an animal-rendering plant in Hanford, Calif., said Dennis Luckey, vice president of Baker Commodities Inc., a Los Angeles-based processor of animal byproducts that operates the facility.

Mr. Luckey said the cow had died at a dairy he couldn’t immediately identify, saying that information was in the hands of the USDA.

The plant renders cows that have died to make commodities such as “high-protein ingredients for poultry feed and pet food,” according to Baker’s website.

During the British mad cow scare of the 1990s, people eating beef and cats eating cow byproducts got the disease, but dogs did not. 

The USDA is issuing assurances that the system is working since mad cow prions from this cow did not get into the food supply for people or pets.

My assessment: The risk of you getting this disease from eating beef is extremely small.

You don’t find this reassuring? Eat your veggies!

On Tuesdays, I answer questions about nutrition in NYU’s student newspaper, the Washington Square News.  Today’s is about youthful immortality.

Question: Many students have expressed that, being so young, they can eat whatever they want and stay thin. What kind of implications does the type of food we eat have on our body weight? If a student is thin but eats bad foods, are there still detrimental effects? Additionally, at what age does what you eat tend to have the biggest effect on you?
Answer: It’s not only youth that keeps college students trim. It’s the lifestyle: running to classes, late nights studying or partying, irregular meals, eating on the run. Once students get past the hurdle of the “freshman 15” — the weight gain that comes from unlimited access to meal plans — most do not gain weight in college.

It’s what happens afterward that counts. Even the most interesting jobs can require long hours in front of a computer or chained to a desk. Eating out of boredom becomes routine and, once middle age hits, it’s all over. The metabolic rate drops with age, and you can’t eat the same way you used to without putting on pounds.

The college years are a great time to start behaving in ways that will promote lifetime health. If you smoke cigarettes, stop while you can. Don’t binge drink. Practice safe sex.

As for diet, eat your veggies. Whenever you can, eat real foods, shop at farmers’ markets and learn to cook. Cooking is a skill that will bring you — and your family and friends — great pleasure throughout life. If you cook, you will always have the most delicious and healthiest of diets at your fingertips.

You don’t know how? Try an Internet search for “free cooking lessons online.” Mark Bittman’s Minimalist videos, for example, make things simple with results that can be spectacular.

Do the best you can to eat well now, and think of it as easy life insurance.
