Food Preferences?We’re Born With Them
People taste and smell things very differently, which is why one person loves broccoli and another person can’t stand it. This means it may be impossible to convince your child to eat foods he hates. And our taste buds also reveal whether or not we’re alcoholics.
Our senses of smell and taste are controlled by 1,000 genes, over half of which are completely inactive. 50 of these 500 inactive genes are switched on in some people, but not in others, which may be why tastes differ. Every human has a different pattern of active and inactive odor-detecting receptors, depending on which genes are switched on and how sensitive we are to them, and people from different ethnic groups taste and smell things differently.
