just a reminder that everything you think you know is, in fact, completely wrong.
they've only found it in the leaves, which are actually poisonous to humans in both cases (although you'd have to eat a shitload for it to kill you, you'd also have to eat a shitload to get the vitamin d. a regular american salad bowl full of tomato & pepper leaves would be pretty much deadly.). so, it's not particularly useful.
you have to wonder, though. can we crispr this? 'cause that's the kind of thing i'd like to see gmo technology applied towards - making food better, not just increasing profits. and, this is a specific nutritional hole that would be deeply useful for a lot of people.
