grapedrink said:Sanitation/solid waste disposal probably has the biggest impact in human lifespan. Followed by antibiotics and other medical advances.did. It's reasonable to conclude that our food had something to do with our increased lifespan.
Grains are certainly the most efficient way to feed a large population. Most of human history would have loved to have an endless supply of cheap calories. Although aside from being able to easily fulfill the caloric intake required for survival, most grains are relatively low in nutritional value.
Fair points too. I didn't say that food was THE biggest factor, just one factor.
I still say that most of our health problems associated with food are related to three things: quantity, and microbiome, and genetics.
