Are plant-based proteins on your mind? For vegetarians and vegans – as well as curious carnivores – invigorate the protein in your meal prep with our vegetable-kingdom suggestions below. The main dilemma with plant-based proteins is that many of them aren't complete proteins. (In other words, they don't contain all nine of the essential amino acids that our bodies cannot produce on their own necessary to creating protein.) Meat and eggs, for instance, are complete proteins, but beans and nuts aren't. Complete proteins are crucial, so consuming a wide variety of plant-based proteins is a good way to obtain the necessary variety in amino acid profiles that leads to obtaining all the essential amino acids without eating meat. From vegetables to beans to nuts, many people – vegetarian, vegan, or not – already naturally consume a wide variety of plant-based proteins, provided they're maintaining a nutritious, healthy diet. Most people know about tofu, but what about its soy cousin tempeh? Similarly, nuts are commonly cited as a source of protein for herbivores, but what about seeds? We're calling out chia seeds, but there's a whole world of plant-based proteins out there. Check out these and two more below.
