Are Dietary Preferences Genetically Determined?
Results of a large study of the dietary habits of identical twins suggest that many dietary preferences have a genetic component. As reported in Twin Research and Human Genetics, 41%-48% of an individual’s leaning towards one of the food groups was influenced by genetics.
I am the father of identical twins. I can attest to them having almost identical food preferences. One child does not drink liquid milk unless she is eating a chocolate cupcake, while the other kids will drink milk occasionally by itself. One child prefers to avoid the olives on pizza while the other eats them. Those are the only differences that I can recall.
