115.Alberta is a 20 year old who has been a vegetarian for 3 years. She comes to you for advice regarding a statement by the Meat Promoters of America organization: “… vegetarians are at risk for protein deficiency because they cannot consume all of the essential amino acids necessary for healthy individuals.” Which of the following would be the best advice for Alberta?

a.She should consume dairy and egg products at every meal to ensure that she meets her essential amino acid needs.

b.She should avoid the “limiting” amino acids because they are limiting her ability to maintain proper protein status.

c.Because the statement is basically true, she should consider eating small quantities of meat every day in order to avoid protein deficiency.

d.Although many individual foods do not provide all the essential amino acids, she could consume complementary proteins throughout the day to receive all the essential amino acids she needs.

117.What is complementary protein nutrition?

a.a dietary program that involves eating vegetable and animal proteins on alternating days

b.a strategy that combines plant proteins in the same day to improve the balance of essential amino acids
