I eat 2 table spoons of yogurt first thing in the morning. No gut issues at age 83. I picked up that habit growing up in India where my mother made yogurt at home from buffalo milk every day. My parents always had 2 cow-buffaloes in barn, their milk was richer, and we had plenty of homemade butter & buttermilk from it. No hormones ever!
I met a guy who was crippled from arthritis. He found some raw milk (outlawed by the FDA), and was cured.
