Every year the holidays put stress on our health sensibilities. We indulge ourselves, we overeat, drink alcohol and generally take liberty with our bodies. Invariably we can develop a sense of guilt over our excesses. Then there are the traditional New Year’s resolutions and the attempt to negate the past month’s indiscretions. I have noted personally and professionally an increase in health-conscious people using cleansing diets. Friends, students, and even colleagues are using them as a recovery method for this extended period of less-than-healthful behaviors. I decided to take a skeptical look at the so-called cleansing diets. What are cleansing diets and are they a good method to get yourself back into shape? Does a cleanse actually do anything and could it be a health panacea or is it another in a long line of marginal health claims?
