No they're not. Cow milk, fresh from the udder spoils in something like 16 hours. Most people cannot tolerate the milk, even if you're lactose tolerant, and it has various hormones in it that if you drink it long term would, uh, let's just say one would be able to notice the difference in your body in the swimming pool, especially if you're male.
To fix this it is processed in food factories that you can describe as squeaky clean massive installations of ceramic tiles and shining steel.
Raw milk is generally better tolerated than homogenized/pasteurized milk. However, in the early 1900s, as supply chains lengthened and the travel time for largely un-refrigerated milk from cow to table increased to days, we found that milk was a primary source of food-borne infections. The absolute risk was still low, but the relative risk was high. Thus, pasteurization became common and in most places, mandatory.
People have drunk raw milk for millennia and have not suffered from hormone-related effects..including people on dairy-centric diets. If you're talking specifically about rbGH, it's very easy to find milk free of it, which I would recommend anyway - I'd hazard a guess that's more common. It’s disputed that it has any ill effects, but I’m totally on board with not risking it.
Everything else aside, powerlifters aren’t recommending crazy diets like gallon-of-milk-a-day (GOMAD) and bodybuilders aren’t paying out the nose for human breast milk because milk has estrogenizing effects.
How do you propose they fix the milk in processing? Are you saying they are removing hormones from milk before bottling? I need some data about all these things you are claiming.
When you heat proteins they become unstable. Long chains become unstable first. So when you heat suddenly or not that high long chains break, but proteins still remain proteins, they just have a very high chance of losing their function.
Sorry, I’m comparing a cows body with its heart and skin to keep out pathogens and immune system to protect it and mouth to ingest nutrients, vs a steel bioreactor with steel skin and piped nutrients and a clean room/disinfectant for an immune system.
