Lactose in enough quantities gets my tummy rumbling in a bad way so I’m trying out alternatives.
Oat milk in hipster coffee drinks is pretty good.
Soy milk as a protein and calcium beverage is fine. Tastes OK.
There is lactose-free milk too but that is still suspect. Either it’s not all the way lactose free or too much of any kind of dairy quakes my intestines.
Look into bile acid malabsorption (BAM). It’s surprisingly common. In the U.S. you don’t commonly use the SeHCAT machines so they prescribe cholestyramine and see if it helps. Give it a go. Very few side effects and you have a lot to gain if it works. Plus if you take it long term you actually reduce your cholesterol levels.
