If we had to choose but one food group, on the basis of sheer nutrition, it would certainly be vegetables. Vegetables are loaded with vitamins and minerals and have been shown to provide protection against a variety of illnesses. When buying vegetables, choose those that are firm and bright, with a fresh, light scent. Don’t buy older vegetables, those that are dried out, shriveled, moldy, cracked, or with an overly strong aroma. Both taste and nutrient value will be compromised.
