子牛が育つのを助けるように作られているミルクが人間にも適していると我々の多くが信じていることを分析するのは驚くべきこと。他の動物のミルクを飲む種は地球上で人間だけ。更には、乳離れが終わってからもミルクを飲み続ける種は人間だけ。このことは乳牛にとってもノーノーなこと。乳牛がミルクを飲むと死亡率が上がり、実際に骨を折りがちになることを示すいろんな研究がある。
It’s remarkable to analyze why many of us believe that milk, which is designed to help calves develop, is also suitable for human beings. We are the only species on the planet that consumes the milk of another animal. Furthermore, we are the only species on the planet who continues to drink milk after weaning. Even for cows, this would be a no-no. There are multiple studies showing that drinking milk for a cow leads to an increased mortality rate and actually makes bones more prone to fracturing, not less. One example would be this giant study from researchers at Uppsala University in Sweden.
