Research is supportive of milk supplying vital nutrients used in childhood development. [44] At this time, evidence does not link rBST-treated milk with adverse health outcomes for children. [45] Several studies have looked at the relationship between type 1 diabetes and infant feeding. Environmental triggers that may elicit an autoimmune reaction is the mechanism in which is being studied. Some studies have shown early exposure to bovine milk may predispose an infant to type 1 diabetes, whereas other studies show no causality. [46]

IGF isn't the only hormone found in the food supply. Ranchers have been fattening up cattle with sex hormones—most notably estrogen—since the 1950s. Today most beef cows in the .—except those labeled "organic"—receive an implant in their ear that delivers a hormone, usually a form of estrogen (estradiol) in some combination with five other hormones. (These hormones are not given to chicken and pigs because they don't have the same growth-promoting effect in these animals, although antibiotics are given to all three species for similar growth-promoting reasons.)

Claims for GH as an anti-aging treatment date back to 1990 when the New England Journal of Medicine published a study wherein GH was used to treat 12 men over 60. [45] At the conclusion of the study, all the men showed statistically significant increases in lean body mass and bone mineral density, while the control group did not. The authors of the study noted that these improvements were the opposite of the changes that would normally occur over a 10- to 20-year aging period. Despite the fact the authors at no time claimed that GH had reversed the aging process itself, their results were misinterpreted as indicating that GH is an effective anti-aging agent. [46] [47] [48] This has led to organizations such as the controversial American Academy of Anti-Aging Medicine promoting the use of this hormone as an "anti-aging agent". [49]
