Vegetables are full of vitamins and minerals and have lesser calories than meat or egg. However, they don’t contain as much protein per serving as meat. In addition, the proteins that they do contain are “less complete” than those in meat, as they don’t contain all of the amino acids that the body needs. So how do vegetarians and vegans get all the amino acids they need? Well, they need to make sure that their diet includes a variety of different plant proteins, including nuts, legumes, soy-based products and grains as well as fruit and vegetables. This variety ensures that their bodies get the various amino acids necessary.
