Hummus, black beans are two legumes I went my whole life without eating and all of a sudden a few years back it was being touted as "super food"

“Whole grains, fruits and legumes are some of the most health-promoting foods on the planet. They are not responsible for the epidemics of Type 2 diabetes or obesity, and their avoidance may do harm.”

Lets just say that with my genetics, those foods didn't exist in that part of the world.

I think it's been nothing but marketing propaganda like so many other things.
