If you’re vegetarian, you may have heard the question: “Where do you get your protein?” The good news is, there are plenty of plant-based protein sources to meet your needs! While animal products are considered complete proteins, meaning they contain all nine essential amino acids, plant-based proteins can also provide all the essential building blocks your body needs. Some plant foods, like quinoa, soy products (like tofu and tempeh), and amaranth, are naturally complete proteins. However, most plant-based sources are considered incomplete, meaning they lack one or more essential amino acids. The key to getting adequate protein as a vegetarian is to eat a variety of protein-rich plant foods throughout the day. In doing so, you can ensure your body gets the full range of essential amino acids necessary for optimal health.
Protein needs vary for every individual, but the general recommendation is 0.8 grams per kilogram of body weight (2). However, if you’re an active person, you may need closer to 1.2-2.0 grams per kilogram in order to support muscle repair and recovery.
Vegetarians have plenty of options to reach their protein goals. Some of the best sources include:
Proteins are made up of amino acids, nine of which are considered essential because our bodies cannot produce them on their own. While some plant-based foods, like quinoa and soy, contain all nine essential amino acids, many plant sources lack one or more, making them incomplete proteins.
That being said, by thoughtfully combining different plant-based protein sources, you can ensure your body receives all the essential amino acids it needs. This approach is known as creating complementary proteins. Some classic examples include:
A vegetarian diet can absolutely provide enough protein—as long as you plan wisely. By incorporating a variety of the plant-based protein sources we discussed, you’ll meet your needs while also enjoying a diverse and nutritious diet. Whether through whole foods or plant-based protein powders, there are plenty of ways to fuel your body and thrive on a vegetarian diet!
