The primary distinction between goat and cow milk is that it is healthier because it doesn't include casein, which is necessary for lactose intolerants because casein can exacerbate the immune system. Given the size of fat globules, goat milk may also be simpler to digest than cow's milk. Goat milk contains more protein, calcium, minerals and good fats. It has more vitamin A, calcium, potassium, riboflavin, and niacin than cow's milk does.
