An interesting example in this direction might concern nutrition (T.C. Campbell-T.M. Campbell II, The China Study, BenBella Books, Dallas 2006): a very important, meritorious and unavoidable approach to cancer prevention, but that still requires a critical vigilance. In recent years we have witnessed in particular the phenomenon of preventive dieting to protect from illness and its relapses: whole grains, legumes, seeds, vegetables and fruit, following a diet that ranges from vegetarian to vegan and to macrobiotic and distorts completely our Western eating habits. From these approaches also derive the most diverse practical applications, with an endless supply of courses, seminars, workshops, organic food stores or trying to be such, kitchen equipment etc. not always only inspired by the well-being of the patient. Sometimes this preventing food can turn into an additional stressful lifestyle.
