The book written by Dr. Porter is amazing, and if milk is really that great and useful as he describes, that might become a revolution. He recommended his patients milk diet for 41 years. Dr. Porter's book won't interest a teenager or a truck driver with a high libido, but it may interest both if either is not as healthy as they'd like to be. A dental cavity tells about ill health, something working inside the body. Dr. Porter's book tells what happens when the milk diet is given for four to eight weeks, it's an unbelievable journey. Large quantities of raw milk, that is, four to nine quarts per day isn't exactly something one does for fun, but when you consider heart disease, providing one rests during the curative period, is cured in five to eight weeks. Very interesting reading that opens eyes to many things!
