Food preferences are learned

All the foods that you regularly eat are ones that you learned to eat.  Everyone starts life drinking milk. After that, it’s all up for grabs. 

But in today’s food culture, many people seem to have acquired uncannily homogenous tastes: food companies push foods high in sugar, fat and salt, which means we are innately incapable of resisting them but that the more frequently we eat them, especially in childhood, the more they train us to expect all food to taste this way.
