Since humans are the only species to drink milk after infancy, it is necessary or even natural?

Humans are omnivores, which means we naturally eat all sorts of different plant and animal foods. We drink milk and eat milk products because they are nutrient-dense foods that taste good and are readily available. Human beings have raised many different grazing animals for their milk, including sheep, goats, camels, water buffalo and others for thousands of years. These animals are able to eat grass, a substance humans can’t digest, absorb its nutrients and turn it into a versatile food that is an important source of essential nutrients. Traditionally raised on land not suited for cultivating crops, these animals and the food they provide have helped humans thrive worldwide. We’ve been depending on milk as an important source of nutrition since before recorded time. While we support the consumption of dairy products, we recognize that drinking milk is a personal choice.
