Eat French fries, gain weight?

A reader, Thibault H writes:

So Harvard University came out with a study that news reporters are saying tells us that those who tend to eat more potatoes gain x amount of weight over 10 years…What do you make of this?…could it be possible that potatoes themselves are not the culprit and rather those who tend to eat more potatoes have a fattier diet or perhaps more sedentary lifestyle.

It could indeed.  The study, which came out in the New England Journal of Medicine last week, looked at the weight gained by more than 100,000 people who had filled out diet questionnaires in 1986 or later.  It correlates what people said they ate with weight gained over periods of 4 years:

The results show that people who said they habitually ate potato chips, potatoes, or fries—as well as the the other foods in the top part of the diagram—were more likely to gain weight.

People who reported frequent eating of the foods in the lower part of the diagram were likely to have lost weight.

What fun!  The study assigns pounds of weight gained or lost to specific foods.

The study also did a more detailed analysis.  This showed that French fries were linked to the greatest weight gain: 3.35 pounds over a 4-year period.  If you habitually eat French fries, you may have a hard time controlling your weight.

No surprise.  I recently ordered a side of fries in an excellent restaurant and was floored by the size of the order Eat a small handful: no problem.  But this order surely hit 800 calories.  Fortunately, there were four of us to share it.

Here’s how I explained the study to Katherine Hobsen of the Wall Street Journal (June 23):

Marion Nestle, New York University professor of nutrition and public health, expressed surprise that potato products were linked with more weight gain than desserts like cake, cookies and doughnuts, which contribute the most calories to the American diet, other research shows. She says she suspects people who eat potato chips and fries also tend to eat too much in general, making these foods markers for a diet leading to weight gain.

The new Dietery Guidelines “policy document” has a particularly entertaining chart of the leading sources of calories in U.S. diets.  Here are the top six, in order:

  • “Grain-based” desserts (translation: cakes, pies, cookies, cupcakes, etc)
  • Breads
  • Chicken and chicken mixed dishes (translation: fingers)
  • Sodas, energy, and sports drinks
  • Pizza
  • Alcoholic beverages

Potato chips are #11 and fries are #17.

This new study provides evidence supporting what everyone surely ought to know by now: eat your veggies!

P.S.  Here’s Andy Bellatti’s take on this study.  His point: it’s not the carbs, it’s calories.

Latest court ruling: Pringles are potato chips (sort of)

Ah the British.  So ahead of us in so many ways.  A British court has ruled that Pringles have enough potato in them to qualify as crisps (translation: potato chips) and, therefore, are subject to a Value Added Tax of 15%.  Procter & Gamble, the maker of Pringles, argued against the tax.  Pringles, it says, are not crisps.  Why?  Because their shape and packaging are “not found in nature.”   Tough, said the court.  Pringles are 42% potato.  That’s enough to qualify them as crisps.  Under the law, crisps get taxed.

Pringles are 42% potato?  OK, but what else do they contain?  Here’s the ingredient list: DRIED POTATOES, VEGETABLE OIL, RICE FLOUR, WHEAT STARCH, MALTODEXTRIN, SALT AND DEXTROSE. CONTAINS WHEAT INGREDIENTS. (You will be relieved to note: No artificial ingredients.  No preservatives.)

Hey: potatoes are the first ingredient!  I say tax ’em.

Update May 25: Here’s what Advertising Age has to say about the Pringles-as-a-vegetable idea.  Pringles, it says, was able to supply the entire world with its product out of one factory in Tennessee, precisely because of its infinite shelf life and packaging.  Ordinary potato chips, alas, get rancid after a while.

Hot potato: food fight looming over WIC package

Let’s see if I can explain what the latest food fight is about. The potato industry is talking about a lawsuit against the USDA to allow white potatoes to be purchased with WIC vouchers. WIC is the federal food assistance program for women, infants, and children; the program gives mothers vouchers for certain foods.  This WIC “package” includes only one fresh vegetable – carrots. The USDA is proposing to expand the WIC food package to include other fresh fruits and vegetables–but not white potatoes. I suspect that the rationale for this exclusion is that French fries made with white potatoes are already among the top three vegetables eaten in the U.S. and that nobody needs more of them.

Here’s what a representative of the white potato industry has to say: “The problem with it is there is no scientific justification for excluding potatoes from the program…potatoes are an excellent source of magnesium, potassium and calcium. In fact, they are bigger sources of those nutrients than spinach, broccoli and carrots, respectively.” Maybe, but it’s how white potatoes are eaten – loaded with fat, salt, and calories – that turns them into junk foods. The potato lobbyists are hard at work. Stay tuned.
