From Real Food to Macronutrients
I'm fascinated by the concept of unintended consequences. We try to accomplish something, and the blowback from our efforts ends up sabotaging our goals in ways we didn't foresee. In this case, the McGovern Committee had wanted to help us avoid heart disease. Instead, the major effect—a highly problematic one—was to change the way we talk about food. And that change in language has contributed to our galloping epidemic of heart disease and other killers.
Before the committee, nutritionists, doctors, and policy-makers spoke of whole foods: fruits, vegetables, grains, nuts, meats, fish, butter, eggs. After the committee publicized its guidelines,
we stopped talking about food and instead referred to the macronutrient components of food: fats, carbohydrates, and of course, protein.
"Carbs" in general weren’t the problem, of course. The problem was that people were eating processed, refined carbs instead of fresh whole fruits and vegetables, beans, and whole grains. After all, green leafy vegetables are carbs, and so are broccoli, cucumbers, red peppers, and onions, and those are some of the healthiest foods on earth. But because of our focus on macronutrients, we aren’t really thinking about those specific foods. We say “carbs”—and think starch.
Even to think about starchy carbs as a separate category distorts the picture. There’s a world of difference between a bowl of steel-cut oatmeal and a sugar-sweetened cereal made from refined flour; between some boiled garbanzos or black beans and a fried corn chip or potato chip.
Moreover, some “carbs” are mainly fats. Muffins, for example, are anywhere from 40 to 50 percent fat by calories, yet they are unfairly lumped in as a carb. Ditto McDonald’s french fries—over 43 percent of their calories come from the oil in which they are fried.
Some diet gurus even began to demonize fruit, conflating the natural sugars that occur in fruit with dead, processed, white sugar. This despite the fact that fresh, whole fruit is one of the healthiest foods there is, full of fiber, vitamins, and phytochemicals. If there is one food that could be said to be created specifically for human consumption,
it would be fruit.
