Evolutionary Explanations

Humans orginate from hnter-gathers and thier diet mainly consisted whatever was avaole in their enviroment

?
Adaptive. provides valuable source of energy. Vital as didn't know when nect meal was. Calories less availble with EEA, so adaptive for humans to develop preference for high calorie foods. Provides them for the longest period of energy
Preference for fatty foods
1 of 18
4-5 year olds. Found foods more calorie rich were preffered by children than sweetness
Gibson and Wardel
2 of 18
Startd due to decline in plants from reducing forests. Rich in fat and high in energy, availble all year round. Gave early humans essentual suppplies of amino acids, minerals, nutrients required.
Preference for meat
