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?
The other day I ordered a burger and they put tomatoes on it even though I asked them not to. I was about to complain, but decided to take a bite anyway and…huh. The tomato had no flavour whatsoever. I used to not like the taste of tomatoes but how could I object to this?
So what does this mean? Are my taste buds not functioning like they used to? But I spent lunch looking it up and apparently, there is a fair consensus that tomatoes, along with a host of other fruits and vegetables, really are blander today than when I was a kid. For something I never liked, this kind of works out but…
My wife, a keen gardener of heirloom tomatoes, says it’s because the varieties that sell commercially are bred for long shelf-life and nothing else.
Ah that would certainly explain it.
My working theory had been that maybe they were being selected for size à la strawberries, which have grown almost comically huge in recent years. But it’s as though nature can only provide a set amount of flavour per fruit, and by growing it larger, it only gets diluted over a greater volume? But I haven’t been able to determine whether fast food tomatoes are behemoths since they are already cut up.
Not quite, but close! Molecular plant breeder here.
There is no set “limit” to flavour but it’s a complex trait that is easy to lose if you don’t select for it. If you breed for size, and don’t track taste, it’s very easy to leave the flavour-producing aspects unchanged, thus resulting in a “dilution”. Furthermore, you’re often actively selecting against flavour, indirectly and unintentionally, by selecting for shelf life - if something doesn’t ripen, it won’t over-ripen and spoil.
This is what has historically happened to a lot of produce but it doesn’t have to be the case - modern breeding lets us breed for flavour and nutrition too! Heirloom varieties can offer some reprieve, but for all their taste they tend to be quite unproductive and sickly (ofter “heirloom” means inbred and that does not produce very fit organisms).
Good news is, new varieties are being bred that have it all - yield, taste, and nutrition! It’s just hard to convince consumers and businesses to switch over to new varieties, as you don’t really buy according to the flavour, just the looks.
Greetings from the UK ;)
Thanks for such an in depth answer. Is there a good place to buy seeds for newer strains like this?
You’re welcome 😊
What we can do in terms of breeding varies significantly between crops - tomato’s a breeze, apples are hard, potato used to be a nightmare but is improving rapidly. If you’re interested in modern seed, I’d recommend turning to a breeding company.
For example, Rijk Zwaan are a major supplier in Europe for a number of crops. https://rijkzwaan.co.uk/home
Happy growing!
