Most of us don’t eat as much fruit and veggies as we know we should, but that goal might now be a bit more achievable. Scientists in Spain have engineered a new “Golden Lettuce” with 30 times more nutrients than the regular green stuff.
Designed for third world countries with actual issues of underconsumption of Beta-Carotine, it got regulated away by first world countries who went "ew icky GMO"
To be technical it was first world companies exploiting the uneducated in those 3rd world countries into asking for suppressive regulations, which their lawmakers then abided by.
This is a really big point actually. When I'm growing salad greens, you have to stop giving them nutrients about a week before harvest, so the plant can burn through those saved up nutrients, otherwise it straight up tastes like metal/vitamins.
