I’m genuinely curious. Years ago, I was a chubby young pothead who lived on fast food. Taco Bell, McDonald’s, KFC, you name it—I ate it. Back in college, fast food probably made up at least 50% of my diet. And it wasn’t just because it was quick and cheap—I actually enjoyed it.
But these days, I find myself craving it less and less. Besides being more health-conscious, it just doesn’t hit the spot like it used to. It’s more expensive than ever, mostly bland, and I feel terrible after I eat it. So what’s changed? Is it just part of the enshitification of everything? Have I just gotten old, or has fast food really gone downhill?
It’s not just cognitive. We lose taste buds with age, and the ones that remain shrink and lose sensitivity.
It makes sense if you think about it. Bitterness is associated with a lot of poisons. Sourness is associated with spoiled foods. Having a strong aversion to these tastes during childhood compelled our ancestors to avoid dangerous foods during their most fragile stages of life.
Then of course, sugar is a quick source of energy. It should be a given why a quick source of energy benefitted our ancient ancestors (for whom food was much more scarce.)
In short, that increased childhood sensitivity allowed our ancestors to survive until adulthood.
So parents - next time a kid complains about their dinner being too bitter, take comfort in knowing that if they were ever exposed to actual poison, they’d avoid it with the same urgency.
