I recently received a question about bananas.
Is it true that a full ripe banana with dark patches on the skin produces TNF (tumor necrosis factor) which has the ability to combat abnormal cells? Therefore the riper the banana the better the anti-cancer quality. Please enlighten us.
Very interesting question,
I actually did some research online and found this Japanese journal article, and what I can say is that I am actually quite skeptical. There are a few reasons for my skepticism.
