US Diet Committee Debates Whether Potatoes are Vegetables or 'Starchy Grain' (msn.com) 129

Posted by EditorDavid from the I-yam-what-I-yam dept.
Every five years America's federal Department of Health updates its dietary guidelines with the latest nutrition science, affecting federal nutrition programs and various other government health initiatives.

Now an anonymous reader shared this report from the Wall Street Journal: Botanists count potatoes as a vegetable. But should Americans? The U.S. Dietary Guidelines Advisory Committee has sparked the question... White potatoes, which come in various colors, are classified as "starchy vegetables." But the committee could uproot potatoes from the vegetable bin and toss them in with a broader category of rice, other grains and carbohydrates as the Departments of Agriculture and Health and Human Services weigh updates to national diet guidelines for 2025.

The scientific debate isn't easy to follow. But it sounds like a half-baked idea to Kam Quarles, chief executive of the National Potato Council, a potato-industry group. The dietary guidelines shape nutrition advice to Americans, as well as what foods are served in school cafeterias. Potatoes, according to Quarles, should be respected as a gateway vegetable. "Kids are far more likely to eat" dishes with other vegetables if potatoes are involved, he said.

Not all parents swallow that a trail of tubers leads to leafy greens. Some complained about a Peppa Pig animated cartoon that featured a potato preaching the nutritional value of vegetables. "By the power of vegetables, I am here," Super Potato said, soaring through the sky, singing, "Fruit and vegetables keep us alive. Always remember to eat your five." The U.K.'s National Health Service, for one, doesn't count spuds toward the U.K.'s recommended five portions of fruits and vegetables a day. "It's a giant spud singing it. You're, like, 'Really? A potato's one of your five a day?'" said Dan Greef, the owner of Deliciously Guilt Free, a sugar-free bakery in Cambridge, U.K. He spent years persuading his two children to eat vegetables. Then, he said, "a drawing of a potato tells you it's fine, and you don't listen to your dad...."

Nutrition researchers say the potato contains helpful nutrients, including potassium and vitamin C, but its health benefits are diminished when it is fried. Nearly half of all U.S. potatoes eaten as food go into frozen products, mostly french fries, the USDA found.
For comparison, the article points out that under U.S. dietary guidelines, "corn on the cob is a starchy vegetable, while cornmeal is a grain."

      Although, in the case of tomatoes being vegetables, when botanically they're fruits, was to force people to pay the vegetable tariff on imported tomatoes (paid by the people importing the item, contrary to recent popular belief that they're pay by the foreign producer). From Tomatoes Have Legally Been Vegetables Since 1893 [smithsonianmag.com]:

      Like a lot of America’s history, the great tomato debate was the product of a tariff,” writes Ethan Trex for Mental Floss. After Congress passed a tariff act that imposed a 10 percent tax on whole vegetables, vegetable merchants tried to bring in some tomatoes and not pay the tariff, arguing (as so many misguided souls have since) that tomatoes are, actually, a fruit. Edward L. Hedden, the collector at the port of New York, was having none of it, and charged the tomato-selling Nix family the tariff.

      So they sued, and after six years of arguing, the case eventually made the Supreme Court. “Botanically, the Nix family had an airtight case,” Trex writes. “Legally, things weren’t quite so open-and-shut.” Dictionaries were consulted. Produce merchants were called as expert witnesses.

      But in the end, the defense’s argument of “sure, tomatoes were biologically a fruit, but for the purposes of trade and commerce—that is, the things covered by the Tariff Act of 1883—tomatoes were really vegetables,” won the day.

      The Supreme Court unanimously supported this idea. We eat tomatoes like vegetables, not like fruit. But, like most tiresome arguments over pedantic details, the case was not closed in the public forum.

    • Since we're talking about food for humans here, perhaps the easiest answer is the most obvious; How does the human body react after consuming a potato? More like it consumed a starch, or consumed a vegetable?

      Doubt the answer matters much anyway. Not like those who created the food pyramids of yore weren't being paid by food mafias, so the answer won't actually mean much of anything. The definition hinges on a cure for obesity, said no one.

      • You've hit it on the head here. Tomatoes and Potatoes are in the same family, Nightshades / solanaceae, and you can graft them to grow together on the same plant. That's irrelevant though; what matters for nutrition is how they are used when they are cooked. One is primarily simple sugars and used as a vegetable. One is primarily complex / starchy carbohydrates. For nutrition, that's all that matters..

    • But most of those people could know better, if they were better educated.

      No. Don't confuse education or intelligence with interest. There's some absolute highly educated geniuses out there who don't give a crap about whether a potato is a fruit, vegetable, berry, grain, or whatever, and only care about whether there's enough salt on it when they eat it.

    Asking whether a potato is a grain or a vegetable makes about as much sense as arguing whether the color grey is black or white.

    Let's make a new category, call it "Starchy Vegetables", and put into this group potatoes, sweet potatoes, carrots, parsnips, squash, rutabagas, and plenty of other foods that are nutritious when served as whole foods with all their vitamins in tact, but nasty when the food industry gets their hands on them and processes them into oblivion.

"Whole foods" doesn't fix any dietary problem we have right now. People eat too many calories with sedentary lifestyles. That's problem #1.

      • Swapping out fries for baked potatoes fixes absolutely nothing.

        Not quite true. The fries obviously have more fat, since they absorb some of the fat they're fried in. A baked potato has almost no fat at all. And even if you cook the fries in a "healthy" oil, the oil undergoes a variety of chemical changes when it's heated for a long time, which makes it less healthy.

        Although you could argue that if you load up the baked potato with butter or sour cream, it becomes less healthy than the fries.

      Then get tricky about it. I mean, french fries are typically not all that heavily processed. They may or may not be peeled, then sliced into the fry shape, then, especially in public school kitchens, are actually more likely to be baked than deep fat fried.

      That's a bit different than what most consider "heavily processed", which is where you'd do things like cook the potato, then dehydrate it and grind it into powder, press it into flakes, and sell it as instant mashed potatoes.
