There do not appear to be any other benefits of dairy (apart from being the source of whey protein) and to make matters worse, dairy seems to have detrimental effects to your health. Milk should be for calves (baby cows), most humans have a problem digesting it. I cannot tell you how many patients I have seen over the years whose chronic constipation, irritable bowel syndrome, arthritis, chronic sinusitis and allergies cleared up when they stopped eating dairy. When people come to see me in my practice and I put them on a diet, I almost always remove dairy.
1. Dairy cows are fed the wrong food, which not only changes the nature of the milk but causes health problems for the cows. They are fed soy, corn, cottonseed meal or other commercial feeds, which contain all sorts of things including chicken manure and citrus peel cake, laced with pesticides. These foods are not appropriate for cows, who are ruminants and should be feeding on green grass in the spring, summer and fall and on green feed, silage, hay and root vegetables in the winter. Unfortunately most dairy cows are kept in confinement, given antibiotics and hormones, and never see green grass their entire lives.
