This subject is far too complex to be settled in this forum, clearly.
I do think you’re all pretty much right, in your own ways though. Milk has been unnecessarily villainized in a very generic and broad way by a lot of groups with special interests. (Vegans come to mind. Also known as the most unhealthy people you’ll ever meet.) However, the milk industry is one of the largest industries in the world, and as such, has many means of protection (Examine food labels closely, not only is the sale of milk directly a huge industry, food additives make up a massive proportion of milk sales, and as such the formulas of most major food manufacturers fall under the domain of milk’s net of protectionism). So on both sides of the essential argument you have people skewing the facts. Also accepting that the “actual facts” still aren’t known. We’re essentially still at a very early stage of understanding when it comes to these matters, this includes ‘experts’.
That being said, we’re on here talking mostly about personal experiences. I have a bit of an issue with milk myself, I’ve had to cut way back on dairy products. I’m not really sure why. I’ve tried lactose free products but still there’s something about them that doesn’t settle well. (whey aside, I love it) This may be genetic, however. I do know someone developed serious illness and was diagnosed with ulcerative collitis. After removing dairy entirely from their diet (all aspects) they actually lost pretty much all of their symptoms and returned to normal.
I don’t think it’s as simple as lactose intolerance, or genetic predisposition, or hormonal treatment, or contamination, or allergies…I think it’s a combination of all those things, each interacting with every person in a different way. For some people they might be lactose intolerant but can use lactase and drink milk. For someone else they might have undiagnosed milk allergies and find, therefore, lactase to be ineffectual. Some people may have genetic and lifestyle factors that predispose them to being negatively influenced in the long term by the essential properties of milk- Ie. those who eat enormous ammounts of uncontrolled intake versus highly trained people who know their body’s needs like the back of their hand.
I know it’s a boring post, because I’m essentially saying “there’s no right answer” or “everyone is right”. However, with most of these issues it’s the case, if not all of them.
That being said, sometimes it’s more fun to argue.
So in that spirit…YOU’RE ALL WRONG! and um…Milk causes um, the africanization of honey bees! Run!
