Reasonable nutrition advice from a familiar source. Pediatrician Eden has been over this ground before (Dr. Eden's Diet and Nutrition Book for Children, 1981); here with nutritionist Boyar he again sets out guidelines for children's healthy diets, supported by a push for exercise. The authors begin by going over the basics of sound nutrition: in spite of such headings as ""The Eden Low-Fat, Low-Cholesterol Advantage,"" this is standard stuff. Next come ""Diet-Plan Menus for Healthier Eating,"" cooking guidelines plus meal plans for ages infant to adolescence. Eden and Boyar then give exercise tips for these ages (again, this is standard fare) and finally offer advice on nutrition for the overweight child. Another presentation of the basics, then; nothing at all new.
