The source of protein in our diet does not have to be just animal sources. Increasingly popular are proteins of plant origin (such as hemp, soybeans, peas, rice), which are an excellent protein supplement, particularly for vegetarians, vegans and people who cannot consume milk. Compared to animal proteins, plants contain a different ratio of amino acids, fewer calories and fat. On the other hand, they are a valuable source of fibre, many vitamins, minerals and some of them include chlorophyll. In terms of efficiency, they can boldly compete with whey protein without lactose - milk sugar. Certain plants can be excellent sources of protein, often with fewer calories and fewer potentially harmful effects than animal products. Plant-based protein offers essential vitamins and nutrients and is easier to digest. It's also kind to the environment.
