The conventional belief that light skin evolved as humans migrated north out of Africa has been widely accepted for many years. However, recent research suggests that the origin of light skin may be more closely tied to the advent of agriculture rather than merely the result of migrating to higher latitudes. This shift in understanding revolves around the crucial role of vitamin D and dietary changes, such as a shift from a diet rich in animal-based foods to one reliant on cereal crops prompted by agricultural practices.

Despite deriving 90% of their traditional diet from sweet potatoes, the Tukisenta people exhibit none of the chronic diseases that plague modern societies, such as obesity, diabetes, heart disease, or high blood pressure. This fact would not have been surprising because, since the '90s, high carb-low fat diets have been most popularly recommended. However, this intriguing paradox challenges the newly prevailing "low carb" diet trend and raises important questions about the true culprits behind these health issues. In this post, I will cover their diet and a few other “extreme” traditional diets and discuss the real culprits behind the ever-increasing amount of chronic illnesses.

I will cover the rise of vegetable oils in our diets, along with chicken fats, that parallel our rise in modern diseases like obesity, diabetes, and heart disease.
