If humans started drinking other types of mammal milk we wouldn't be as poor. Imagine selling human milk in the store, it tastes amazing, it's sweet and it'll sell. We could milk dog, cats, pigs, goats, and hippos. For example: Hippo’s milk may also taste like a combination between cow’s milk and watermelon juice.
Some are also of the opinion that it tastes like a tangy, thick yogurt.
Nutrition-wise, hippo milk is quite dense, with one cup having as much as 500 calories.
It’s also said to be high in protein but low in fat.
