Explain why vegetarians and vegans might be deficient in some amino acids
What will be an ideal response?
To make all the proteins our bodies need, we must have a supply of all 20 amino acids. Some of these can be made by the cells in our body, but others must be included in our diet; these are called essential amino acids. A balanced diet is necessary to ensure that we have an adequate supply of all the essential amino acids. Vegetarians must be especially careful in planning meals because some plants contain low levels of certain essential amino acids. Vegetarians and vegans (who consume no animal or dairy products) must select complementary protein sources to ensure that their diet contains all the essential amino acids.
