Panel presentation at the 2nd annual Ancestral Health Symposium 2012 (AHS12): Insulin Signaling – Science and Policy
The Food Pyramid, established by the USDA in 1982, recommended ingestion of 55-70% of calories as carbohydrate. The subsequent 30 years showed a growing epidemic of obesity, metabolic syndrome, type 2 diabetes mellitus, as well as identifiably increased risks for cancer, arthritis and cardiovascular disease. The Food Pyramid has recently been abandoned. Recommendations for carbohydrate intake now are in the range of 40-55% of total calories. Some propose that we should increase consumption of whole grain foods, natural fruits, etc. Other approaches recommend reducing total carbohydrate consumption further than current recommendations on grounds that 90% of the carbohydrates ingested nowadays are sugars or starches that digest to sugars.These are points of discussion, but regardless of specific dietary recommendations, we believe that a new dietary paradigm can be identified that calls for reducing overall insulin signaling. Benefits include reduced risks for type 2 diabetes, obesity, dyslipidemias, cardiovascular disease, arthritis as well as cancers: in short, many of the chronic diseases of our time.The panel and audience will discuss risk factors for chronic diseases and their inter-relations, mechanisms of insulin signaling that appear likely to contribute to these relationships challenges and possible suggestions toward improving dietary patterns.
