The current knowledge regarding effects of organic food on health is unclear. In this study we have focused to yield a consolidated knowledge on health related aspects of organic food. We searched for the MeSH term “organic food” in Pubmed search engine (other terms used for search are: Organic food-18296 articles, organic food and health-4018 articles). Studies done on organic food, related to health, free full papers available in English were included for review. From the total of 2,215 articles, 1805 were excluded due to studies which were not related to organic food, studies without abstracts. Out of remaining 410 studies, 338 studies were excluded due to nonavailability of full studies. Finally, 32 studies were selected after removal of articles not related to health. Out of 38 studies included, 9 studies focused on humans, in which 3 studies showed decreased pesticide content, 6 studies showed decreased risk of pre-eclampsia, hypospadias, cardiovascular diseases, etc. 14 studies focused on nutritional quality which showed increased lutein, PUFA and n-3 PUFA, antioxidants, analgesic and antiinflammatory properties, etc. A total 9 studies focused on microbiological aspects which showed increased prevalence of microbial contamination, increased antibiotic susceptibility, etc. From the available studies, the effect of organic food on health is not convincing enough to recommend widely. More follow-up studies on humans, with large sample size might possibly enlighten the concept of organic food and its effect on health in future.
