Vegans are strict vegetarians who don't eat or use any animal products at all - even milk chocolate.
Sam from Rutland writes about why he decided to become a vegan.
"Over the summer of 2003 I became involved with an organisation which investigates factory farming and cares for rescued animals and the pictures I saw in their investigation reports shocked me into going vegetarian.
I'd never thought about where my food really came from before, I just assumed it was from happy animals on happy farms but now I've learnt that this isn't the case.
Becoming a vegan
Seven months later and I'm now a vegan - recently I've learnt about the atrocities in dairy farming and egg production and I read about the health benefits of a vegan diet.
Now I avoid anything derived from animal sources - including flesh by-products such as leather, gelatine, wool and animal rennet and I also don't eat eggs or dairy products.
Instead I eat lots of fruits and vegetables, seeds, nuts, beans, pulses and also fortified foods such as tofu, soya and mycoprotein.
I also have an appetite for vegan chocolate and I like to eat fake meat occasionally!
I'm a member of The Vegetarian Society and The Vegan Society and I am looking forward to promoting this year's National Vegetarian Week (23-29 May) and World Vegan Day on 1st November."
