Several strategies are now used to lower igf 1.
Lower igf 1 with diet. In one animal study feeding a zinc depleted diet to rats for 14 days. How naturopathic can you get. In rodent studies polyphenols from green tea significantly reduced igf 1. The runners had similar bmis to the plant based eaters but still ate meat and dairy.
Based on the observed opposite effects of a low protein diet in subjects 50 65 year old versus those 65 and older and on the major drop in bmi and igf 1 levels after age 65 we hypothesized that older subjects on a low protein diet may become malnourished and unable to absorb or process a sufficient level of amino acids.

Those eating vegan had significantly lower igf 1 levels and higher igf binding proteins than those just eating vegetarian suggesting that the more plant based one s diet becomes the lower one s risk of fueling growth hormone dependent cancer growth. 18 21 reducing protein may lower igf 1 in humans more effectively than caloric restriction. Blood tests showed that those eating a low fat plant based diet still had lower levels of igf 1 than long distance runners. Zinc is an essential mineral for brain health.
