Evolutionary Explanations for Food Preference Essay Plan
1. Describe in detail human's preference for meat. Milton claims that without animals, it is
unlikely that early humans could have secured enough nutrition from a vegetarian diet to
evolve into the active and intelligent creatures they became.
2. Outline briefly in a couple of sentences taste aversion.
3. Critical Point 1: This theory has strong evidence to support it. Gibson and Wardle showed
that the best way to predict which fruit and vegetables would be preferred by children was
not by how sweet they were, but their calorific value. He found that bananas and potatoes
were particularly calorie-rich and were more likely to be chosen by the children
demonstrating an evolved preference for calorie-rich foods. Therefore, this theory can be
used to explain why we prefer pizzas and hamburgers to vegetables and fruit.
4. Critical Point 2: There is some argument as to whether humans were vegetarians in the EEA.
However, anthropological evidence by Abrams demonstrates that all societies display a
preference for animal food and fats, also it would not have been possible for rarly humans to
be completely vegetarian as they would not have been able to get sufficient calories from
the plants and grains available. Therefore, this is more evidence for human's preference of
meat as it contains quite a lot of calories.
5. Critical Point 3: However, this theory has a flaw. After infancy, it is evident that different
cultures eat more of particular types of foods. For instance in China they eat a lot of rice and
noodles, this could be down to availability of the food. Therefore, we can say that evolved
factors are still important today, but these are modified by our experience with different
foods, with culture partially determining the degree of such experiences. As a result of this,
nowadays evolutionary preference is not universal.
