The author of numerous books on nutrition (e.g., Nutrition for Women, LJ 10/15/93) and the editor of the monthly Nutrition Report, Somer has compiled ample information from scientific research that links nutrition to depression, mood swings, seasonal affective disorder (SAD), and premenstrual syndrome (PMS). She includes over 100 tables, charts, and worksheets to help readers access their own mood swings plus nutritional menus and recipes to help counter these swings. Her only false step is recommending that anyone short on time purchase pre-cut vegetables, since vegetables begin losing nutrients when they are cut. Only those who are truly interested in nutritional research will be motivated to read this book from cover to cover, but it will serve as a good reference for any reader. Recommended for large nutrition collections.-Loraine F. Sweetland, Rebok Memorial Lib., Silver Spring, Md.
