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.
A plant-based diet may be key to lowering risk for heart disease. Penn State researchers determined that diets with reduced sulfur amino acids — which occur in protein-rich foods, such as meats, dairy, nuts and soy — were associated with a decreased risk for cardiovascular disease. The team also found that the average American consumes almost two and a half times more sulfur amino acids than the estimated average requirement.
Amino acids are the building blocks of proteins. A subcategory, called sulfur amino acids, including methionine and cysteine, play various roles in metabolism and health.
“For decades it has been understood that diets restricting sulfur amino acids were beneficial for longevity in animals,” said John Richie, a professor of public health sciences at Penn State College of Medicine. “This study provides the first epidemiologic evidence that excessive dietary intake of sulfur amino acids may be related to chronic disease outcomes in humans.” Continue reading →
Eat more plant foods…increase dietary fiber…choose natural foods over processed…get your nutrients from whole foods, not supplements. For an easy way to follow all of this sound dietary advice at the same time, simply up your intake of foods from the legume family. Legumes, which include beans, lentils, split peas, green peas, and peanuts, are thought to be one of the first cultivated crops and have been consumed by people around the world for over 10,000 year, according to Tufts Health & Nutrition Update.
Unfortunately, legumes are no longer a staple food in most American diets. The Dietary Guidelines for Americans recommend adults consume one to three cups of legumes per week (depending on calorie requirements), but average intake is less than one cup weekly.
