At one time I was drinking a gallon of raw whole milk a day. Like water there are limits as in all things which will kill you from sugar to beer.
For a health consideration, colostrum, (the milk for newborns) has a healing effect on humans with various health issues, beginning with intestinal. Caprine is the better milk suited to human consumption, especially with infants with colic. Bovine is the most common, and in that Ayrshire, Jersey and Brown Swiss are a better class of milk than the Friesan Holstein, which is what dominates the American dairy industry based on production instead of quality. Real Ayrshire butter is an orange yellow and does not need food coloring to make it yellow.
What should be the real question on this site is the abuse of dairy cattle by corporate agriculture of herds 1000 to 10000 in confinement, who employ Mexicans which abuse those animals who never see the light of day. They are fed high corn diets to produce milk and literally burn out as animals in a three years. it is inhumane compared to the dairy farmers who were small when America needed to occupy people with income in a non inflation America, when people once could make a living trapping 100 mink a year or 100 fox, where cows were commonly in production on small family farms past 13 years of age.
That is the nasty side of this border wall slight of hand not being spoken of in the use of Mexicans in corporate agriculture in abusing animals, which in turn drove family farmers out of business.
