Human dietary habits, like those of other mammals, involve a transition from maternal milk in infancy to other sources of nutrition as they grow older. However, a notable distinction for humans is the enduring preference for cow’s milk over milk from their own species.
While it’s true that around 68% of the global human population is lactose intolerant, cow’s milk remains immensely popular. The primary reason for this enduring preference may simply come down to taste. Historical evidence reveals that various types of milk have been consumed by humans for thousands of years. For example, East African populations were consuming goat’s milk as far back as 6,000 years ago, while sheep’s milk was favored in parts of Europe and the Middle East. It was during the Bronze Age, approximately 3,000 years ago, that cow’s milk gained prominence as a suitable option for weaning babies who were transitioning from maternal nursing.
Following this historical development, cow’s milk gradually became the dominant choice for dairy consumption. There were practical reasons for this shift, such as cows being easier to milk compared to other mammals. Furthermore, cow’s milk boasts a creamy and sweet taste in contrast to the slightly sour flavor of goat and sheep milk.
While there are now a multitude of alternatives, including various plant-based milks, available to consumers, cow’s milk continues to be a staple in the diets of over six billion people worldwide. This enduring preference for cow’s milk is a testament to its historical and sensory appeal, even in the face of alternative options.
