I was a fish eating vegetarian for some years. Had no trouble maintaining my weight, but often longed for a burger. While I eat meat now, it is only rarely.
Experts agree plants should make up a large part of a healthy dietary pattern. Humans eat plant roots (carrots and radishes), stems (asparagus and celery), leaves (leafy greens), seeds (including whole grains), flowers (broccoli, cauliflower, artichoke), and the seed-bearing “fruits” of plants (including fruits, vegetables, beans, and nuts). All are packed with important health-promoting nutrients, and countless studies have found associations between consuming diets higher in unprocessed plant foods and lower risk for a wide range of disorders such as cardiovascular disease, cancer, obesity, and diabetes.

But recommendations to eat a “plant-based” diet can be misleading. “I really dislike the term plant-based to describe a preferred or healthy diet,” says Dariush Mozaffarian, MD, DrPH, dean of Tufts’ Friedman School of Nutrition Science and Policy and editor-in-chief of Tufts Health & Nutrition Letter. “Not all animal-based foods are bad, and most of the worst things in the food supply are technically plant-based.” A vegetarian diet built on pizza, macaroni-and-cheese, and baked goods may be “plant-based,” but it’s far from a healthy dietary pattern.
