Plant-based protein sources are foods derived from plants that provide essential proteins for the body. Common examples include legumes like lentils and chickpeas, as well as tofu and tempeh, which are made from soybeans. Nuts and seeds, such as almonds and chia seeds, also contribute to protein intake, making them popular choices for those following a vegetarian or vegan diet. These protein sources are not only nutritious but also offer additional health benefits, including fiber, vitamins, and minerals. Incorporating a variety of plant-based proteins can help meet daily protein needs while promoting overall health and well-being.
