Vegans also do not use any material off animals, such as accessories containing leather or feather. Ovo-lacto vegetarians are vegetarians who also eat eggs and dairy foods in addition to plant foods. The type of vegetarianism determines which nutrients are at risk of being deficient in such vegetarian’s diet.
