nowday with the development of different sciences, it has become clear that islam's instructions and prophet mohammad's teaching (pbuh) have been based on reason and wisdom and with the scientific studies, the philosophy behind many of these instructions and teachings has been settled in the mind. the great prophet and the pious imams have recommended the use of many herbs and vegetables as sources of food and medicine. in this study we only mentioned the medical qualities of four types of them, i.e. mushroom, garlic, squash and vinegar, and we have also mentioned a few recommendations of islam's nutrition rules. the consumption of mushroom in islam's instructions can be seen in a number of religious narratives whereas it has been mentioned as a hygienic vegetable. eating garlic has been an emphatic advice by prophet mohammad (pbuh) to his followers and in case of considering social concerns its consumption is repeatedly suggested. also using garlic as a victual for gaining good behavior and mental health is again islam's recommendation. vinegar preperation from different vegetables as a food seasoning or taste exists in the islamic narratives and the therapeutic effects of these vegetables have been proved in numerous scientific studies. finally, we conclude that the holy religion of islam which is the last and most complete divine religion has paid great attention to the physical and psychical health of human as much as it does to religion and spirituality and in the prophet's ( pbuh ) teachings, sanitation, individual and social health have been as a must and religious duty and man is prohibited from anything that is harmful to the human body. considering a balance in the use of vegetable and carnivorous food is one of the serious recommendations of the religion of islam and this matter has been confirmed in researches and experimental studies.   key words: vegetarianism, great prophet's (pbuh) teachings, mushroom, garlic, squash, vinegar.
