Last week I learned some fascinating information about every
child’s least favorite food (and what has now become my most favorite) Brussels
Sprouts. According to Now I Know, a daily
fact email that I highly recommend subscribing to if you’re the type of person
who want to have super random cocktail party conversations, the reason children don’t like sprouts is
biological!
Brussels sprouts contain
a chemical compound in them which triggers a response from the bitter-detecting
taste buds on our tongues. And as Popular
Science notes, we lose taste buds as we age, and the bitter
taste therefore isn't as strong as we get older. But children take the full
brunt of the bitterness. Further, PopSci argues,
children's aversion to bitter foods isn't just stubbornness, but perhaps
evolutionary -- the overwhelming taste signaling, perhaps, a toxin in the food
being eaten.
And for those grown-ups who still don’t like them, well, they’re
just genetically messed up.
As reported by the BBC, a typical person has "25 types
of bitter receptors" on their tongues. But some people -- "due to
their genetic make-up," as stated by Dr. Lisa Methven, a food and
nutritional services professor quoted by the BBC -- have more. Dr. Methven
estimates that these people are super-sensitive to bitter foods -- "they
experience the bitter tasted up to 60 times higher than someone with an average
number of taste buds." Understandably, these people typically hate
Brussels sprouts.
Fortunately for both The Husband and myself, our genetics
are normal…at least regarding our bitter receptors.
