Yes I advocate what I consider the ultra-healthy end of nutrition. I do this because my body needs it. Without it my life would go downhill rapidly.
But most people do not necessarily need to go that far. If that's you and you want to consider giving up meat there are an increasing number of "quality" meatless alternatives. Top of the tree right now is the impossible burger which is soon coming to restaurants in the UK.
Interestingly Google are bidding ridiculous amounts of money to buy the company, based on consistent reports of blind tests where meat eaters prefer the impossible burger. I will never eat one, but to others it may appeal.
