Proteins, also called protein, are very important to our body. They provide calories and amino acids. Our body needs no fewer than 22 of these amino acids, of which the body can make 13 itself. We have to get the rest of the amino acids from our food and are called essential amino acids. Many people get this from animal proteins, but there are also many vegetable proteins. This is important for people who want or need to eat vegan. If you are lactose intolerant, for example, you cannot tolerate dairy products, but animal welfare and the environment are also important reasons to eat vegan. Plant-based food also contains proteins, but the amino acid profile of vegan products contains far fewer essential amino acids than that of animal products. If you eat vegan or vegetarian, it is therefore important to take this into account.
