The Science of Fasting

Searching through Amazon Prime yesterday afternoon, I came across a documentary entitled The Science of Fasting.  Initially released in Europe, in 2011, it presents the findings of scientists from Russia, Germany, France and the United States.

Long thought to "cleanse the body," fasting may offer significant benefits for those with a variety of chronic diseases, including the metabolic syndrome, cardiovascular disease, autoimmune disease and cancer.  Directed at the general public, the documentary explains the body's physiologic response to food deprivation and points out that these adaptations have developed in concert with the evolution of our species; indeed, for most of our history, food was not always readily available.  Animal studies have suggested that fasting may re-prime normal cells, improving their function, while placing a significant stress on abnormal cells (e.g. cancerous or inflamed cells); indeed, at the University of Southern California, fasting mice demonstrated better tolerance of chemotherapy that did their cohorts.

Like "Forks over Knives (see A Plant-Based Diet)," this documentary correlates eating habits with our risk of disease; both films offer persuasive evidence but individuals are advised to discuss these dietary measures with their health care provider before stopping medications or significantly altering their diet.  Good nutrition is vital to both the prevention and management of disease and fasting (even for brief periods) may be ill-advised in some cases.  Nevertheless, I recommend viewing both documentaries and considering the points that are made; the fact that most humans in "developed countries" overeat is undeniable.
