A professor suggests that the increasing problem of obesity in the United States might be attributable to an inherited predispos
ition to love the taste of sweets and fats. Although these foods helped our ancestors to survive food shortages, today they are easily available and Americans are eating too much of them. What field does the professor's suggestion belong to?
This is the study that looks at the characteristics that we inherited from our ancestors .
Due to evolution our inherited traits have changed over time in order to adapt with the change in the environment or with the changing conditions of each time.
This may mean that even though our ancestors were able to tolerate such fats it was because it was necessary for their survival at that particular period and their body demanded it .
However the time and the conditions have changed for us, we are no longer living under conditions that demand that much fats in our bodies hence those traits have weakened .
