I want my food to be tasty (who doesn't?), but my basic philosophy about food is that its purpose is to nourish the body and sustain health. If what you're eating shortens your lifespan, it kind of defeats the purpose of eating food.
I almost never eat fast food. I eat a low fat, low sugar, high fiber diet. I eat chicken, fish, only occasionally beef or pork. I eat a lot of fruits, vegetables and whole-grains.
My heathly eating evolved over time, first by cutting back on fat, then adding more fiber, and now I've been watching my sugar intake.
Anybody else out there a health eater?
