A modest little cookbook, based on a sensible, well-balanced ""hospital"" diet -- like those mimeographed regimens your doctor will hand you -- and which uses no sugar substitutes or ""artificial"" ingredients. There are, however, plenty of herby embellishments, lots of wine dishes, yogurt, and cottage cheese. Good, simple recipes, and there's a minimum of advice about food preparation: most hippy readers are already hip. With all the necessary calorie and substitute tables. Cheering ideas to contemplate on the first (and worst) day of your diet.
