Lean meat is a great source of protein, but you can get all the protein your body needs without it. Here’s a primer on vegetarian sources:

• Legumes. Beans, peanuts, and lentils — different types of legumes — are loaded with protein. In addition, they’re cholesterol-free, low in fat, and high in fiber.

• Soy. Tofu, soy milk, and tempeh — all made from soybeans — are excellent meat replacements. Soy is considered a complete protein, meaning it contains all the amino acids humans need to eat (because our bodies don’t produce them).

• Nuts. Pistachios, almonds, walnuts, and other nuts pack protein, nutrients, and essential fatty acids. While nuts are high in fat compared to other plant foods, it’s the healthy unsaturated kind. Still, it’s important to keep portions in check to avoid too many calories. Aim for just a handful of nuts or a tablespoon of nut butter a day.

• Seeds. Also high in essential fatty acids, seeds are excellent protein sources. Pumpkin, sunflower, sesame, and flax seeds are rich in minerals, vitamins, and antioxidants.

• Perfect pairings. While whole grains and beans each contain some protein, neither is a complete protein on its own. But when paired, they have all the essential amino acids. Try winning combinations like black beans with corn tortillas, lentils and rice, or garbanzo beans with whole wheat couscous.

Replacing all or some of your protein from meats with plant proteins can be part of a healthy diet. Look for more vegetarian know-how online.
