Ross, author of The Diet Cure, here offers a prescriptive plan designed to relieve a variety of ailments from seasonal disorders, stress, irritability and depression. Ross believes that many of these annoying and, in some cases, severely disabling disorders can be relieved through a change in diet and nutritional supplements. Readers are asked to first determine which of four "false moods" they suffer from: a dark cloud, blahs, stress or too much sensitivity. The survey is simple and the questions will immediately resonate with readers: for example, someone who is suffering from the blahs is likely to have difficulty focusing or require a great deal of sleep. Armed with their survey scores, readers can then turn to the appropriate chapter to learn which diets and supplements will be most helpful.Particularly reassuring are the author's detailed explanations of why she advises a particular strategy. While Ross is an advocate for nutritional supplements, she provides a sound overview for all her recommendations. (Nov.)
