I'm basing this on absolutely no specialized knowledge or research of my own, but it has to be processed food. Like it just has to be, in about 2-3 generations we've just utterly abandoned tens of thousands of years of fairly consistently eating variations on plants, cooked animal flesh, and fermented variations of the same, in favor of a staggering array of highly pre-processed chemicals. The results are obvious and instantly visible everywhere: massive increases in obesity, chronic conditions like fatigue and depression, and so on. We're poisoning ourselves. The only other contender that comes to mind is being constantly surrounded by and consuming plastic. Which is basically another thread on the same basic issue of our industrialized diets. Hey maybe I'm wrong. But probably not right?
