I appreciate your answers very much. Presently I have some practical questions and need their answers. We live in UK and here all the eatables contain some gelatine (wheat /pork/beef/meat) in them. Examples of such food include ice-cream, biscuits, medicine etc. My questions in this regard follow:
1) If we don’t know whether the ice-cream has gelatin or not what should we do? Sometimes the management also does not know about them.
2) My wife bought medicine for lactation for my two months old son. We came to know that the shell of cod liver oil tablets contains gelatin in the ingredient. What should we do now? Origin of Gelatin is not mentioned.
3) What about Mcdonald's fish Burger? Can we eat that or not?
