I have dealt with IBS for a very long time. Am lactose intolerant and have had problems post gallbladder surgery. A few years ago diagnosised with gastroparesis and have been on a variation of FADMAP.
I recently have landed on Soymilk tasting better than the others and is higher in protein.
I tolerate the almond yogurt in small amounts. What I have found is that it is a slow process of elimination - what works and what does not. Wishing you the best in this journey.
