Which of the following is classified as a plant-based protein?

Beans are classified as a plant-based protein because they come from plants and contain a significant amount of protein, fiber, and essential nutrients. They are a versatile food source often used in vegetarian and vegan diets as a primary protein option. Beans, including varieties such as black beans, kidney beans, and lentils, are not only high in protein but also provide various health benefits, such as improving digestive health and supporting heart health due to their fiber content.

In contrast, salmon, eggs, and sausage are sources of animal-based proteins. Salmon is a fish rich in omega-3 fatty acids and protein, eggs provide high-quality protein and a range of vitamins and minerals, and sausage is typically made from meat, making these options animal-derived rather than plant-based. This distinction is important for individuals who may be following specific diets, such as vegetarian or plant-based eating patterns, where incorporating plant proteins like beans is essential.
