My thought as well. Milk, cheese, and eggs are unfashionable at the moment, for whatever reason; but that doesn't make them less valuable or desirable.

Is animal welfare the reason for dairy goods being out of fashion? I doubt it; it's easy to come by humane milk and eggs, although humane cheese, butter, kefir, yogurt, etc. are less common. And yet, vegans are the new vegetarians -- even the Jains are going vegan -- while we also get the paleo diet with its own reasons for being anti-dairy...

There's also hostility to bread. Bread and milk are historic European staples; a part of me suspects that hostility to these (at least in white Americans) is really about hostility to the past.

The milk that many regions of the world consumed was genetically different to the most common milk that humans consume today. It has been proven that a2 milk is digested differently to a1 milk.

I switched to a2 milk and the difference to my digestive system was extremely obvious. Time will show that for many people, if they consume milk, it should be a2 milk.

If anyone else wants a quick summary of what you can find on Google Scholar for this: There is currently no strong evidence in support of the idea that A2 milk has better digestive or other health properties than A1 milk. Most of the stuff I found out there concluded that there was no significant difference, and the few that I found on the rest of the Internet were contradicted elsewhere.

This is correct and does not contradict anything I said. It is quite easy to try it for yourself and see if it does anything. Of course you will want to avoid consuming large amounts of other dairy sources while you are trying it.

In order to build confidence in the results of a personal experiment like this one, it's best to (double-)blind it as much as possible and log lots of concrete data every day (e.g. keep track of your bowel movements, sleep quality, alertness levels, blood pressure, etc). This should help limit the impact of any (conscious or subconscious) preconceptions or other psychosomatic effects.

Also, change as little else in your life as possible while you're performing the experiment to control for confounding variables.

While anecdotal evidence is useful it doesn't prove anything. Research is stronger, but more limited in scope.
