The author, a naturopathic doctor, follows his bestselling guide to healthy eating based on blood type (Eat Right for Your Type) with a program designed to provide optimal conditions for fertility as well as for pregnancy and childbirth. D'Adamo, with the collaboration of freelance writer Whitney, utilizes current genetic research to explain the chemical reaction between blood type and food. Someone, for example, with Type O blood who wants to conceive should eat a diet that includes beef or lamb, as proteins from these meats help to create a beneficial physical atmosphere for conception. A woman with Type A blood, however, in order to create the best conditions for conception, should eliminate meat from her diet and consume fish and seafood as her chief sources of protein. Divided into sections for blood Types O, A, B and AB, D'Adamo provides nutritional strategies, including recipes, concerning detailed advice on what foods to consume, avoid, and how frequently to eat. According to the author, following these guidelines will facilitate trouble-free pregnancies and childbirths. He also suggests exercises for before and after birth that are based on type. To best recover from childbirth, an AB woman should rely more on stretching exercises, while a Type O mother can engage more quickly in aerobics. Included also are nutritional plans, based on blood type, for the new baby. This is a very useful tool for new parents with a strong interest in alternative medicine. (Apr.)
