Macrobiotic diet

Does it work?

There are no clinical trials or reliable epidemiological data available to suggest that this diet is effective for cancer prevention.5;12. Vegetarian diets seem to confer some protection against cancer but it is unclear whether this effect also extends to the macrobiotic diet.13 Such a postulated effect could most likely also be achieved by diets that are more nutritionally balanced and less complex to prepare. 

There are a number of anecdotal reports of cure of established cancer through adherence to a macrobiotic diet;3,8 but to date these reports have not been confirmed in clinical studies. 10,12,14
