Have been pondering this question of how some people can reach their potential in height,intelligence, disease resistance while living off bad foods and being raised in poor environments. Knowing not all will, but take for instance you have some stories of athletes being in the ghetto with probably a lot of processed foods and milk that's probably not grass fed( as I read that's the best) and still reaching their supposed potential that helps them be the best in sport. Or some people who live off junk food, drink alcohol, and bad sleep cycles can still go to class the next day and crush a class without a hiccup. Right now the only way i see it is that their ancestors at the right foods and since amino acids are mainly consisted of hydrogen,nitrogen,oxygen,carbon that whatever they eat no matter how bad their body will use it the best way since it's in their genes from the previous generations diet. Off base?
