But what if healthy eating could be simpler than all kinds of rules? What if all we have to do is eat more fiber? After all, for all the disagreements between specialty diets, the part they seem consistent about is vegetables. Granted, there's some disagreement about fruit, since some fruits have a fair amount of natural sugars in them, and beans, which pack a lot of complex carbs in with the fiber and protein. But everyone agrees that eating more veggies is good for all of us, especially the green leafy ones.
