Poor Choices Primary Obesity Cause


A study based on 20 years of monitoring eating habits, other lifestyle habits and the health change (all started healthy) of 121,000 professional men and women who  participated thru the Nurses Health Study and the Health Professionals Supplementary Study, was published last week by Harvard University Department of Public Health. The conclusions cite poor food choices, not calories, not aging, not other popular myths as the primary cause of overweight and obesity. For example, the foods associated with the greatest weight gain included potato chips (for each one increased daily serving, (+1.69 lb) more weight gain every 4 years), other potatoes (1.28 lb), sugar-sweetened beverages (1.00 lb), unprocessed meats (0.95 lb), and processed meats (0.93 lb). Of note, several foods associated with less weight gain when their consumption was actually increased, including vegetables (−0.22 lb), whole grains (−0.37 lb), fruits (−0.49 lb), nuts (−0.57 lb) and yogurt (−0.82 lb). Other factors such as sedentary activities including watching TV and two little or too much sleep were also factors. While each factor was a small contributor to weight gain or loss the combinations added up to an average weight gain of one pound per year, which is about the National average. An excellent video presented by the co-author and professor of epidemiology and medicine is currently available. The full report is summarized on the School of Nutrition website.

Once again as with colon cancer and heart disease we see red meat and processed meat consumption, as significant factors. CAFO red meat production including corn feed production is the primary cause of massive soil loss and nutrient pollution in the Mississippi, and Pamlico Sound watersheds and is about half of Chesapeake Bay Watershed nutrient pollution.
