Quorn is not such a good choice. And not that safe. About 5% of consumers get ill after eating it (that's a really high percentage!). And the long term side effects of eating this experimental fungus are not known, but given that a huge amount of the population suffers with chronic fungal infections, I wouldn't advise eating this fermented fungal fake meat. It's quite simple folks; if you like meat/meat shaped items; eat meat! If you are turned off by meat type foods (like me), eat beans, nuts and seeds. Neither path will kill you. But the pretend meat just might. Some more info:
