Material Detail

Lactose is a key sugar found in milk, which many of the Asian community cannot digest. Recently, DNA analysis of the ancient Mongolians confirms although they raised Horses, cows, Yak and sheep, they did not have the ability to digest the sugar lactose. Today in Mongolia, although they milk every form of cattle, 95% of their people still lack the ability to digest lactose. Additionally, modern Mongolians in today's time are only able to digest dairy by utilizing a particular bacteria that digests the sugar for them. It does so by turning the dairy into products such as yogurt or cheese.
