Proteins

Proteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development in children, teens, and pregnant women.

Because the amino acids that make up proteins are numerous and people have different needs, biological value is slightly subjective. Most people need the same high biological proteins to build healthy bones and muscles. How people get their protein varies. Many vegetarians receive all the essential amino acids that their bodies require without having to eat meat. They do this by substituting the amino acids missing in vegetables with nuts, beans and legumes.

A high biological value or low biological value in a protein does not make it better or worse than any other nutrient. However, knowing whether a protein has a high biological value helps a person make effective decisions when it comes to dietary consumption. High biological value proteins come from animal sources, while low biological value proteins come from plant life. Protiens also take longer to digest than carbohydrates, helping you feel fuller for longer and on fewer calories—a plus for anyone trying to lose weight.

You probably know that animal products—meat, eggs and dairy—are good sources of protein; unfortunately, they can also be high in saturated fat and cholesterol. What you may not know is that you don't need to eat meat or cheese to get enough protein. Here are some good vegetarian and vegan sources, and tips on how to add them to your diet today. 

Green peas

Foods in the legume family are good sources of vegetarian protein, and peas are no exception: One cup contains 7.9 grams—about the same as a cup of milk. (For the record, women should get about 46 grams of protein per day, and men need about 56.) 

Quorn 

Quinoa

Most grains contain a small amount of protein, but quinoa—technically a seed—is unique in that it contains more than 8 grams per cup, including all nine essential amino acids that the body needs for growth and repair, but cannot produce on its own.

Nuts and nut butter

All nuts contain both healthy fats and protein, making them a valuable part of a plant-based diet. But because they are high in calories—almonds, cashews, and pistachios for example, all contain 160 calories and 5 or 6 grams of protein per ounce—choose varieties that are raw or dry roasted. Nut butters, like peanut and almond butter, are also a good way to get protein, says Penner: "Look for brands with as few ingredients as possible—just nuts and maybe salt," she says. "Skip the ones with hydrogenated oils or lots of added sugar."

Beans

There are many different varieties of beans—black, white, pinto, heirloom, etc.—but one thing they all have in common is their high amounts of protein. Two cups of kidney beans, for example, contain about 26 grams (almost the same as a Big Mac, which has 25 grams!). 

Chickpeas

Also known as garbanzo beans, these legumes can be tossed into salads, fried and salted as a crispy snack, or pureed into a hummus. They contain 7.3 grams of protein in just half a cup, and are also high in fiber and low in calories. 

Tempeh and tofu

Foods made from soybeans are some of the highest vegetarian sources of protein: Tempeh and tofu, for example, contain about 15 and 20 grams per half cup, respectively. "They're highly nutritious, and they can really take on the taste and texture of whatever type of food you're looking for,"

Leafy greens

Vegetables don't have nearly as much protein as legumes and nuts, Gerbstadt says, but some do contain significant amounts—along with lots of antioxidants and heart-healthy fiber. "If someone is eating a lot of vegetables—and a wide variety of different types of vegetables—it will certainly add up to a good amount of amino acids," she adds. Two cups of raw spinach, for example, contain 2.1 grams of protein, and one cup of chopped broccoli contains 8.1 grams.
