Plant proteins are plants, plant products, or plant derivatives that are rich in protein. As such, they are viable as meat substitutes to a large extent and capable of supplying the necessary dietary protein.
Plant proteins come in many forms, including legumes, cereals, vegetables, pulses, fruits, and seeds. However, unlike animal protein, they tend to have more specific protein content in varying amounts.
For vegetarians and vegans, plant proteins are crucial because they hardly have any other natural protein sources. Even non-vegans are encouraged to adopt this diet because of how healthy it is. Plant proteins are rich in other essential nutrients with much fewer carbohydrates, and fats.
