Interesting. Summarizing: pineapples contain a compound which breaks up collagen. No proof it does that to the human body, or floaters specifically.

But if it did, I’ve got terrible collagen and so I won’t be eating pineapple everyday, regardless of what the Taiwanese pineapple council would like me to do.

Even so, how would a meaningful amount of it be delivered to the eye from oral ingestion without damaging anything in between?
