Dr. Ron Najafi traces how sugar consumption exploded from 5 pounds per year in our ancestors to 125 pounds today. The shift accelerated through the 1960s with ultra-processed foods and high-fructose corn syrup, which increased fructose intake roughly 25-fold with wide metabolic consequences.

So here's what our sugar consumption has done over the past 200 years. Our ancestors, getting fruits and vegetables and the occasional honey out of the ground and out of trees, consumed about five pounds of sugar per year. So here's the 19th century with the growth of the sugar industry, C and H and Domino and Texas, Louisiana, Hawaii. And here's stabilization when price equaled demand, but the sugar was still in five pound bags. Here's the rationing of World War II. And then we went back up to the same level. But then we have the advent in 1960s of ultra processed food which sent consumption soaring. And then of course, we had the sugar for fat debacle of the 1970s. We also had the introduction of high fructose corn syrup which made things go even higher. We have increased our consumption of this molecule, fructose, by 25 fold. Not 25%, 25 fold. And the question is, what kind of effect can that have on you? And the answer is it's affecting all of these pathways that we have just talked about.
