Pretty much never and honestly if you look at ALL the research there really isnt any health benefits to doing so either, same goes with veg.
I certainly don't belive all this 5 a day fruit and veg our government pushes is required or even healthy. I don't eat veg other than backed beans, Red cabbage leaves and sweet potato as I fucking hate veg. Most veg if i can force it down plays havoc with my digestive system. I do believe you can get by just fine without fruit and veg. I will say in the last 5 years since I've been eating bananas I've never had a cold. I notice the guys at work who eat a lot if bananas are never of sick either. Scientific, hell no haha just throwing it out there.
