A chatty, diffuse collection of tips for parents in the old-fashioned, doctor-tells-patient style. Apart from ""your family doctor,"" says Isenberg, most others offering nutritional advice are either food faddists or ""consumer activists busily hopping on the bandwagon."" What he has to offer is some unimaginative menus (cottage cheese; Ry-Krisps; small, unbuttered potatoes); some answers to frequently asked questions (""what is the best food, nutrition-wise?""; ""how important is portion size?""); and some tips for success (""always read labels""; eat more slowly). This is all loosely grouped into bare basics on nutrition; tips for pregnancy and feeding the newborn; a word to vegetarians; and some special advice for teenagers--""mostly girls;"" who seem to suffer more weight problems than boys. Isenberg, who is sometime out-of-date, ascribes little importance to breakfast and recommends snacking-when-hungry over eating regular meals. For current, well-organized guidance, see Helping Your Child Grow Slim (p. 862), by Warren Silberstein and Lawrence Galton.
