Hi Rabbi. Thank you for always responding clearly and promptly. May Hashem always grant you success. How do I know if a particular ingredient is raui le achila or not? Or if it has a bad flavor or a good one? Many ingredients are unknown and I can hardly pronounce them. If most of these added chemicals are not considered halachically foods, then are there some that would be problematic due to their source and flavor? How would I know which ones they would be? Thanks.
