"I think ther eis a disagreement between orthodox rabbis with each other on whether it can be eaten..."
If so then provide a source please. By the way many of the protein shakes and other things are made from stuff like this. And thats why their are some that have an O U sign saying it isn't made from that (but usually from WHEY.
I know some orthodox jews who will not eat at certain glatt kosher restaurants. (I dont' remember the reason, though). so i have no source and you have to understand, I don't have access nor time to find soruces like you do who studies in yeshiva all day. So please be fair...show me that orthodox rabbis agree on everything with each other in regards to kashrut and I'll listen, even though i'm goign to keep askign questions.
And don't dismiss my arguements if i dont' have sources...teach me.
Yes, that is true. That shouldn't bother others though because they have good reasons. 1 reason is because even with their being a reliable person watching over ,etc one cant be exactly sure that every vegatable for example was checked for bugs. And since they are doing it all day anything can happen, they could forget, they could mess up, etc. Their are those that will say that they want to be strict upon themselves not to eat out, but eat vegetables for example that they or their wifes personally hand washed and checked.
Their are also others that say- soo what if it says Glatt Kosher, do you know the guy? Is he really reliable? etc. For example their was a case where this guy was selling non-kosher meat and pretending it to be kosher for some time, until he got caught.
Their are also those who never eat meat because of the above reason and more (because in America its all about making $, and its all made by mass production).
And also about Glatt Kosher meat itself, some only eat meat that is Beit Yosef (according to the Shulhan Aruch), what is concidered only Glatt Kosher is technically not recognized in the Shulhan Aruch, but Askenazim allowed it. But even within Askenazim some only eat Beit Yosef, because of the concern that the other opinion might be wrong.
BUT the very least Jews should do is eat Glatt Kosher, and it shouldn't bother us about those who want to be strict, infact they should be looked up to for their actions.
