Bitter Tastes

Only go here when you have time and if you are sitting down. There’s sweet, of course. Then sour. Then salty. And when the Greek philosopher Democritus took up the question several thousand years ago, he added bitter and now umami, so that makes five.

Our taste receptors recognize bitter tastes as one of the essential tastes we perceive. Some people seem to enjoy Brussels sprouts, while others can’t stand them and why? There are simple explanations, it is very likely a measure of how much genetics contributes to a trait.

In terms of genetics we can use heritability as a measure. When 100% means all of the variation in a trait can be accounted for entirely by genetics, and a heritability of 0% means that variation is accounted for entirely by environmental factors.

Did you ever think to test your gene pool?
