It’s multi pronged wrong. The form of calcium is wrong, and ends up being toxic ( many areas of research now showing regression of age related disease by removing excess calcium from the body/brain) and there is toxicity issues from concentration in milk. Just the PCbs in ice cream is startling when looked at, But the overall pesticide load is damaging. It was a great addition campaign, “ milk, it does a body good”, but it was a total lie. Mostly the useful component of milk is iodine (residue from teat cleaning during milking) and vitamin D (not enough, but they do add some). Raw milk is its own subject matter which has been shown be far better through expirament and testing being it’s natural state without adulteration. There’s a great video where a farmer raises two calf’s, one on raw milk, one on pasteurized milk. One cow develops fine, good weight and growth. Other is sickly and thin and the expirament had to be ended before the calf died.
