While protein is most commnly found in meat products, it can also be consumed through a vegetarian diet. Many nuts and seeds are high in protein, and there are many vitamin supplements that can also be taken. Average fruits, vegetables, and grains also carry small amounts of protein, too. Many products, like protein bars and shakes, can also be used.
Plants such as beans, lentils, chickpeas, quinoa, and tofu are good sources of protein for vegetarians and vegans. These plant-based protein sources can help individuals meet their daily protein needs as part of a balanced diet.
Good sources of protein for vegans include beans, lentils, tofu, tempeh, edamame, quinoa, nuts, seeds, and plant-based protein powders. These foods are rich in essential amino acids and can help vegans meet their protein needs.
A quality protein, for instance, contains all the essential amino acids in the proportions you need them. Milk protein, casein, is the highest quality protein. Egg protein, albumen, is next best. (Albumen is not albumin, a class of proteins found in your blood and other body tissues.) Your body can turn almost anything into its primary fuel, glucose, but it cannot turn fuel into the other nutrients it needs. Food quality is therefore determined by the essential nutrients present in that particular food.
No, flax is not a complete protein as it lacks certain essential amino acids that the body needs.

You can get protein from meat, fish, eggs, milk, and some nuts like peanuts. Some food have artificially added protein like some breads. Tofu is is a great easy to digest protein rich food which is made from soy beans. Soy beans are a source of complete protein; they contains all the amino acids (the building blocks of protein) that the human body needs. It is hard to find all the amino acids that the body needs in one vegetarian food.
Your body uses protein to repair and build muscle mass after a tough strength workout. Protein also helps maintain and repair/replenish skin, bones, teeth, hair and other body structures. So, it is a vital macronutrient (fats and carbohydrates are the others). The three macronutrients and other processes help keep your body in an anabolic state, which aids muscle building. There are two groups of proteins that you should be aware of: complete and incomplete proteins. Your body needs complete proteins found only in foods originating from animals. Examples are eggs (eat the whole egg), chicken, turkey, red meat, milk and other dairy products. Vegans will need to combine non-meat protein sources to get complete proteins.
There are three main types of protein: complete, incomplete, and complementary. Complete proteins contain all essential amino acids and are typically found in animal sources like meat, fish, and dairy. Incomplete proteins lack one or more essential amino acids and are commonly found in plant sources like beans, nuts, and grains. Complementary proteins are two or more incomplete proteins that, when combined, provide all essential amino acids. Each type of protein offers different nutritional benefits and sources, so it's important to include a variety of protein sources in your diet to ensure you're getting all the essential amino acids your body needs.
Some sources of herbivore protein that can be included in a plant-based diet are legumes (such as beans, lentils, and chickpeas), tofu, tempeh, seitan, quinoa, nuts, and seeds. These plant-based protein sources can help meet dietary protein needs for those following a vegetarian or vegan diet.
The best sources of protein for 1-year-old babies are breast milk or formula, as they provide complete nutrition. Other good sources include soft-cooked eggs, well-cooked and finely chopped meat, poultry, fish, tofu, and legumes like beans and lentils. It's important to consult with a pediatrician to ensure the baby is getting enough protein for their growth and development.
Everyone needs a certain amount of protein everyday. If you are replacing protein from other sources, consuming protein drinks on non training days makes sense. On training days, additional protein is recommended.
For bodybuilders, the best plant-based protein sources include tofu, tempeh, lentils, chickpeas, quinoa, and seitan. These options provide high-quality protein, with some offering complete amino acid profiles. For animal-based protein, top sources are lean meats like chicken, turkey, fish, and eggs, along with dairy products like Greek yogurt, cottage cheese, and whey protein. Both plant and animal-based options can effectively support muscle growth, depending on dietary preferences and nutritional needs.
