Raw vegans only have unprocessed plant-based food items in uncooked form. So, the products may be heated, but not beyond a particular temperature. There is some logic behind their actions. Two of those logics are that cooking reduces the nutrients of the food and makes it less digestible, plus cooking amounts to ‘killing’ fresh produce. Raw vegans view uncooked food items as ‘live’ things and cooked products as ‘dead’ ones. For someone who is not all that into the whole concept of veganism, these notions may go over their head.
 
Of course, eating raw food alone will not make you a vegan. You will still have to meet the definition of a vegan: ‘someone who eats no animal-based food and does not use products derived from animals’. If you do not do either of those things, then you may not even be a vegan. Hope this clears your doubt.
