Most people love sugar. Humans started farming around 13,000 years ago and it’s no coincidence that nearly all the earliest crops farmed were high in sugar. Wheat, barley, rice, corn all have a lot of sugar. When we humans were hunter-gatherers (like 99% of our history) sugars would have been very rare treats in our diets. Only when we started settling down and farming did sugars really become a large part of our diets. Archaeologists have dug up human remains from this time period which have shown how the switch from a hunter-gatherer diet to a farming diet changed our bodies. We became shorter, had a huge increase in tooth cavities and generally became less healthy.
