Then, Dr. Alm, an evolutionary geneticist, and Dr. Erdman, a cancer biologist, supplemented the diets of half the mice from each group with yogurt.
They found that the yogurt-eating mice had ten (10) times the active follicle density of other mice, which caused them to have a much silkier looking and thicker fur coat than the other mice.
The two MIT researchers also found that the testicles in the male yogurt-eating mice were 5% larger when compared to the non-yogurt eating mice.
And, the yogurt-eating mice had testicles that were 15% larger than those of mice that ate a diet that was similar to junk foods that humans eat.
The 5/7/2012 ABC News article Yogurt Makes Mice Slimmer, Sexier quotes Dr. Alm: “We think it’s the probiotics in the yogurt. We think those organisms are somehow directly interacting with the mice to produce these effects.”
