Metabolism and Our Choice of Foods

Metabolism and Our Choice of Foods

In our choice-laden grocery stores, with dozens of varieties of foods – hundreds, perhaps – there seems to be a fairly clear awareness of what’s good food, and what’s bad or junk food.

For example, we don’t need a book to remind us that, all else being equal, a plum is a good food, whereas a tub of thick and creamy double-fudge ice cream is a bad food.

Not bad tasting, of course; but, really, you won’t find many fit people eating a vat of ice cream a day, for obvious reasons. So what does this have to do with calories and energy?

It’s this: while you and I can evaluate our food choices and say that something (like a plum) is a healthy source of energy, and something else (like a tub of ice cream) is an unhealthy source of energy, the body doesn’t evaluate. Really.
