Document Summary

Demeter s legacy: rapid changes to our genome imposed by diet. Wanted to know the extent to which the consumption of strach, has exerted selective pressures detectable in our genome. Possible answers include cultural adaptation; changes in the genetic regulation of food metabolism. Populations with traditional starch dense diets had a higher amyi copy # than populations with low starch diets. Amylase concentration was probably low in the saliva of ancestral hunter gatherers. Prevents detrimental effect of wheat and dairy. Energy dense diet essential during pregnancy and early childhood.
