Real soy sauce is made from the soy bean which is considered kitniyot. If you were able to find a kosher l'Pesach brand, it's not allowed for Ashkenazim. There are several brands of imitation soy sauce for Pesach.
Yes.
Not for Ashkenazic (European) Jews.
It has to be labeled as kosher for Passover with reliable supervision. If it has such a labeling, it may be used only by non-Ashkenazim (Sephardim, Mizrahi). It does contain soy, but has no gluten.
I don't think so!
There are a number of companies that make kosher l'Pesach imitation soy sauce. As soy beans are considered kitniyot, imitation soy sauce emulates the taste of the real thing but does not contain any soy.
Real teriyaki sauce, which contains soy sauce, would be kitniyot. There are imitation teriyaki sauces available for Passover.
You can try lactose free milk or soy milk.
Most people can. However, if you are going to eat soy, try to get organic soy otherwise it's probably genetically modified.
No,it would not be advisable.
Soy is good everytime but it's bad for you if you eat it to much
You can eat soy or drink soy milk if you have sigmoid diverticulitis. Whole grains and tough meat should be avoided.
