ELEVATED INSULIN LEVELS- THE LEADING CAUSE OF PREMATURE AGING AND PREMATURE DEATH.
Increased insulin and leptin receptor sensitivity have clearly become the leading candidates for premature death. This results from two pry conditions: Excessive amounts of sugar/grains and processed foods, combined with insufficient exercise.
Previous studies have also found that diets high in sugar and grains are the pry culprit of obesity, and that leanness (more so than food restriction in general) is a key contributor to a long life. One such study was published in 2003 in the journal Science. This elegant study from Harvard confirms that insulin is the major mechanism thru which this result is mediated.
