Why we eat "healthy" and just get fatter

There's an interesting article in the NYT Magazine called "Unhappy meals" about how we eat, focusing on nutrients instead of real food. In our house, we eat real food as much as possible (fruits and vegetables that haven't been canned or pickled or plasticized or dehydrated), but still rely on frozen for variety, and canned for sauces, beans, and those rarely consumed items. We eat bakery bread that is firmer and tastes better than either of my grandmothers could make. We eat small portions of meat, but do eat meat every day. I wouldn't dream of purchasing something labeled a "healthy snack." Read the label! It's like a chemistry text book. We aren't fat.

But what is the problem? Nutritionism may be the culprit, says the author. There are more government regulations, more nutritional studies, more diets (low fat, low carb, etc.), and there's a huge industry of journalists and authors (including the one who wrote the above article) who do nothing but write articles or publish books about what to eat and how to eat it. One nutrition/exercise/health web site I read recently said we are spending more on obesity per day than on the war in Iraq. I haven't crunched the numbers, but that's scary! Read the article (recommended by Janeen who combats food allergies daily in her family) and see what you think.
    On the Women's Health Initiative: "But perhaps the biggest flaw in this study, and other studies like it, is that we have no idea what these women were really eating because, like most people when asked about their diet, they lied about it. How do we know this? Deduction. Consider: When the study began, the average participant weighed in at 170 pounds and claimed to be eating 1,800 calories a day. It would take an unusual metabolism to maintain that weight on so little food. And it would take an even freakier metabolism to drop only one or two pounds after getting down to a diet of 1,400 to 1,500 calories a day — as the women on the “low-fat” regimen claimed to have done. Sorry, ladies, but I just don’t buy it.

    In fact, nobody buys it. Even the scientists who conduct this sort of research conduct it in the knowledge that people lie about their food intake all the time. They even have scientific figures for the magnitude of the lie. Dietary trials like the Women’s Health Initiative rely on “food-frequency questionnaires,” and studies suggest that people on average eat between a fifth and a third more than they claim to on the questionnaires. How do the researchers know that? By comparing what people report on questionnaires with interviews about their dietary intake over the previous 24 hours, thought to be somewhat more reliable. In fact, the magnitude of the lie could be much greater, judging by the huge disparity between the total number of food calories produced every day for each American (3,900 calories) and the average number of those calories Americans own up to chomping: 2,000. (Waste accounts for some of the disparity, but nowhere near all of it.) All we really know about how much people actually eat is that the real number lies somewhere between those two figures."
There are good ideas and points in this article--many we've heard before, but cherry pick. We are bombarded by anti-western this and that, and eco-friendly tidbits by the same journalists who wrote us into obesity! You need to be selective. In the 1970s women were literally pushed out of the home and kitchen; we've been getting fatter since. Now we're being reeled back. Barefoot and pregnant probably won't fly these days. But do try to eat real food.

If you can find it.
