Drinking cows milk became common around 10,000 years ago and is not necessary for humans to live a healthy life
Humans have existed for at least 300,000 years and have only been drinking cows milk for around 3% of that time.
A detailed meta analysis study found that around 68% of the worlds population have some degree of lactose intolerance. This means they typically experience symptoms such as diarrhoea, nausea, cramps and bloating after consuming cows milk.
We are the only known species to routinely consume milk in adulthood and the only known species to consume the milk of another animal.
