I gave up dairy products over a decade agoto obtain optimal health and stop having digestiveissues (lactose intolerant.) I do use tofutti products - the ones that are not hydrogenated.They make very realistic substitutes for sour cream, creamcheese, ice cream. I do get diarrhea when I eat a lot of fat, it seems especiallytoo much foods that have both sugar and fat combined (desserts.)If I eat too much tofutti ice cream (which is easy to do) I am prettysure I will get D in the morning. If I eat too much of any fat in single day, it also causesproblems.I don't eat low fat - I eat moderate amounts of olive oil, avocado,nuts, etc. Nuts seems to be ok for me.
