I stumbled on this article today where they address the question of which is worse: calories from fat or calories from carbohydrates. An excerpt:
There are some interesting questions about whether eating carbohydrate calories versus fat calories will make you eat more calories, but based on what you put into your mouth, it's pretty clear that the source of the calories is really not important.
Then the article went on to talk about the different kinds of fat vs the different kinds of carbohydrates:
... the type of fat is very important, and so is the type of carbohydrate. So we find that trans fats, again, are particularly harmful with regard to type 2 diabetes and heart disease. On the other hand, unsaturated fats are actually beneficial in terms of reducing the risk of heart disease and type 2 diabetes. It's the same with carbohydrates. The total amount is not important. But high intake of refined starch and sugar is related to a higher risk of heart disease and diabetes, whereas high-fiber whole-grain carbohydrates are related to a lower risk.
So, for a guy who's a bottom-line kinda guy, I learned:
-- Don't stress about occasionally eating high-fat foods, except where they're all trans fats.
-- Eat high-fiber whole-grain foods.
Nothing earth-shattering here as that's what the "experts" have been saying for years, but it's good to regularly see it in black-and-white on occasion to know that the state of the art hasn't changed.
