It’s utter nonsense, unless you are lactose intolerant. The mutation that allowed adults to digest milk had such a high fitness value it spread from Scandinavia through the human population like wildfire by evolutionary standards.

- adrian_b 3y agoLactose intolerance is not the only problem with lactose. Those who do not have lactose intolerance split lactose into glucose and galactose, which are absorbed. Like fructose, galactose must be converted in the liver. In people where either the conversion is slower or they consume a lot of dairy, galactose may persist for longer times in the body. In such cases there is an increased risk of eye cataract.
