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.


You’re smarter than you give yourself credit for. When a doctor gives you a medicine that you are not familiar with, you probably google it or ask AI to help you identify it and understand it. If you rely on that for medicine, you can rely on it for this.
Here… I tried something. I asked Google the following.
does lecithin have a taste?
This was the response:
Lecithin generally has a neutral to slightly earthy or nutty taste, but it is typically used in such small amounts that it is undetectable in final food products.
