From what I've been reading, people didn't eat nightshades until maybe the 19th century.
Nightshades contain neurotoxins.
Depending on the dose, just about everyone will get ill or dead.
Some people have obvious and immediate negative effects from eating nightshades (Tomatoes, potatoes, eggplant & peppers.)
How come people go crazy about gluten because it wasn't consumed 50,000 years ago but seem to turn a blind eye towards nightshades?
Please help me understand the apparent double-standard.

Firstly, humans have been consuming gluten from well beyond 50,000 years ago. Gluten is the protein in seeds from the grass family. And grass family seeds (Poaceae) have been consumed for millennia before agriculture. In fact the ease with which certain grass seeds can be harvested (in the hunter-gatherer world) led to agriculture in the first place in some regions. In todays world, gluten disorders affect less than 5% of the population at large. Maybe that many again are affected by Poaceae lectins, but that is speculation because I don't think much controlled study has been done there.
As for the tomato family (Solanaceae) there are many toxins, mostly in the alkaloids realm. In the New World these plants have been consumed for many millennia. The statement, "Depending on the dose, just about everyone will get ill or dead," is probably not true in the practical world. And the idea of finding all the answers in the huge number of glycoalkaloids, tropane alkaloids, and pyridine alkaloids from this family is not likely to garner the formidable research dollars to make the definitive statement. In the short term, this family provides many valuble nutrients, and in the long term some of them are the keys to avoiding certain disasters.
It is worth remembering that the statement, "Depending on the dose, just about everyone will get ill or dead," applies, in the extreme, to about everything, including water; so caution is warranted in every food family and individuals will perform very differently.
All the best, and thank you for reading.
