...And part of the blame belongs to an assemblage of statistics called the glycemic index.
The glycemic index is a list created by Canadian researchers that ranks foods according to how they react inside the body. Popular diet books like Atkins for Life and The South Beach Diet (the latter published by Men's Health's parent company, Rodale) use the glycemic index to delineate which foods are good for weight management and which are bad...
...Joanne Ikeda, R.D., of the department of nutritional sciences at the University of California at Berkeley, points out another flaw: "The glycemic index is fine if all you eat is one food. But we don't do that--we eat a mixed diet. That's where the glycemic index falls apart."
It fails in other ways, too. The more fat (and hence, the more calories) a high-carb food packs, the lower its GI ranking, because fat slows the digestion process. You could make room for Cheetos and ice cream on your list of low-GI foods. And some high-GI foods, such as bananas and oranges, are low in calories and high in vitamins and other nutrients, and belong on your plate.
So what we're saying here is, eat lots of fruits and vegetables and whole grains. It's a simple sentence that would seem like common sense in any other era. But today, it seems like heresy. Because, rather than explain all these complex permutations, many diet moguls simplify things into one easy, three-word mantra: Cut out carbs. ...
