Watched clips. Were bad. Very bad. As in badly made and irritating full of BS anecdotes and such.
Also the "documentary" seemed to concentrate on US milk health problems. I don't really care about US food and it's problems (antibiotics, hormones etc) since I live in Europe. If I were to visit (which I wont) I would probably bring my own food
But Yeah! did some research on the whole bad compounds in milk. One substance got highlighted = the A1/A2 protein aka beta-casomorphin-
7. Supposedly the BCM-7 in A1 milk is bad for you, causes heart disease, type 1 diabetes, schizophrenia, autism and a host of other problems. The A2 milk didn't have this problem. There were studies which kinda confirmed the results but there were also more recent studies which were better conducted with larger test groups which showed no correlation whatsoever with BCM-7 to negative health results.
Also, the person who wrote the whole fearbook about BCM-7 and A1/A2 milk is a professor yes, but not in biology, epidomology or anything alike. He is a professor of Farm Management and Agribusiness. There was also some talk about a New Zealand A2 cattle company.
The type 1 diabetes claim may be legit for infants under 4 months. But there are some variances here, none of which have been confirmed as more than risk factors if that.
1) the BCM-7. Well, it was shown that the BCM-7 isn't actually a risk factor for humans. It even gave good results as a diabetes treatment so... But the bottom line seems to be that the autoimmune type 1 diabetics may have a sensitivity to many other food proteins, hence they create antibodies for said proteins. Healthy children outside risk groups do not create said antibodies.
2) bovine insulin in milk. This may be the more important factor if milk does in fact cause risks for type 1. But this is again about the autoimmune sensitivity and the prevalence to create antibodies against proteins and hormones.
All in all the adverse health effects (if they even exist) are far from proven. My personal opinion is that the BCM-7 thing seems like a scam. Too much speculation with statistics and too little actual medical information.
And as afun fact. He uses a lot of Finnish disease statistics to support his proof. Finland drinks a lot of milk and also has the largest amount type 1 diabetes per capita in the world. However milk consumption here has stayed at same levels even when type 1 diagnoses have increase by 3% annually. Kinda wrecks the correlation a bit but let's not that stop the fear mongering.
