How come there is no disease caused by the absence of carbohydrates? This simple observation suggests that carbohydrates are not necessary for health and are not an essential food in our evolutionary history. This is different from vitamin C or other essential nutrients whose absence will cause scurvy and eventually death.
From an evolutionary perspective, simple carbohydrates, especially sugars and high-fructose corn syrup, are significant contributing factors to the increasing epidemic of obesity, type 2 diabetes, metabolic syndrome, coronary heart disease and many autoimmune disorders. The recommended nutritional guideline of the last forty years to reduce fats and increase carbohydrates were not based upon good science but on ideology influenced by agribusiness and the sugar industry (La Berge, 2008). The recommendations were WRONG AND HARMFUL (Taubes, 2016; see also: https://peperperspective.com/2017/02/18/read-the-case-against-sugar/). It may explains why the obesity epidemic is not caused by eating or drinking too many calories but the eating the wrong type of calories; namely, those found in simple carbohydrates and overly processed foods. The increase in obesity appears highly correlated with the US low-fat diet recommendations published in 1977 as shown in figure 1.

The harmful effects of the simple high carbohydrate diet amplified with a decrease in physical activity interacts with your genetics. People, with a family risk factors of metabolic syndrome (type 2 diabetes) can improve their health by eating a low carbohydrate diet with lots of vegetables, fruit and fats.
