Modern humans consume a limited variety of hybridized plant species repeatedly, unlike ancestors who consumed a much wider variety.

“humans eat essentially 12 species of plants that have just been hybridized to look like many different plants in the grocery store we are eating the same plants over and over and over and again i think that the most toxic parts of plants are roots stems leaves and seeds we are eating the same roots stems leaves and seeds over and over if our ancestors were going to be plants they would have 10x 100x the amount a variety of these plant foods meaning that they even if they were eating plants they would be much more likely to get a bigger variety it's simply not possible for us to do this and this may be one reason that so many people have problems with plants today”
