Mark!
Welp I was writing you a detailed update in case your ‘mark’ was re folate in milk but I accidentally shut down my computer. ARGGHH!!
The quick answer - MAHA (make america healthy again - RFK Jr.) may be at work because last year I saw CDC messages saying it was time to signficantly increase ‘fortified’ folate in foods and just today I went looking and can’t find folate ADDED to milk. There is natural folate IN milk, but often proteins in milk are present which bind the good milk so drinking it doesn’t support very much folate in the body.
In researching my update to my prior post, I found that UHT processed milk (80% of organic milk brands and most shelf stable milk products) do not contain the protein which binds to good folate and makes it unavailable. UHT is ‘Ultra High Temperature’ processed milk. It has to be done right though, because if done poorly UHT processing can taste ‘burnt’.
