I liked Quorn. I used to eat lots of it. It's been very widely available in the UK for over ten years. It's tasty and healthier than meat. But it eating it will make me ill, not because of the "mycoprotein", but because of the milk and eggs in it. Milk and eggs make me sick. No more stilton or fried egg and chips for me.

Some people are physically intolerant to some foods, it happens.
