>>19974361Most northern European white men have only been farmers for a relatively short time, compared to the 1000s of years Mesopotamians, Indians and Chinese have been growing wheat and rice. Before then they were mostly pastoral with only incidental farming,- Germanic tribes settled in one area then moved to another near constantly. Intensive agriculture in Europe only really began in the middle ages with the advent of the heavy plow and other innovations allowing farmers to cultivate the heavy soils. However shortly after this, European civilization rose to great heights, new tools like the scythe (which many places in India still do not use) and innovations like windmills and European successes in trade and conqvest favored intelligence and stymied the dysgenic effect of being farm chattel.
Regardless it was quite a long period lasting from around 800 AD until 1800 AD in most places. White Europeans thus developed the hallmarks of a civilized people, immunity to disease, high tolerance for alcohol, high tolerance for starchy high carb foods. African Americans and aboriginals that eat the western diet suffer health problems whites generally do not.
Generally though it is advise to retvrn to a largely meat diet, perhaps reducing staples to those high in protein like beans. A "ketogenic" diet is not a fad diet, it actually has therapeutic effects, your body will switch to ketone bodies due to a lack of carbohydrates, which can be better utilized by the brain improving concentration and intelligence.
