“…The methodology adopted followed the basic procedures recommended for studies of literature on systematic reviews [23][24][25] . In other words, systematic methods were used to critically identify, select and discuss articles published on the theme investigated and related objectives, materials and methods, as well as results observed, with drawing of conclusions on the corresponding state-of-the-art or available scientific knowledge [23][24][25] .A systematic search to capture scientific articles published was accomplished in the period between January 2003 and May 2011, in the MedLine (National Library of Medicine), Scopus, SciELO (Scientific Electronic Library Online), Lilacs (Caribbean Latin American Literature and in Sciences of the Health) electronic databases and in Google Scholars. The key words used were: fish in combination with food intake (dietary consumption), omega-3 fatty acids, fatty fish, benefits, risk, consumption.…”

A B S T R A C TThe article aimed at identifying and discussing scientific evidences on the benefits and risks of fish consumption the human health. There was a systematic survey for articles published from 2003 and May 2011, at the MedLine, Scopus, SciELO, Lilacs and Google Scholar databases. The key words used were: fish, food intake, omega-3 fatty acids, fatty fish, benefits, risk, and consumption. The search produced 12,632 articles, 25 eligible cohort studies on possible benefits, 61 on risks and 10 studies that assessed the "risk/benefit" relation. Of the 25 works, 14 suggested a preventive effect of fish consumption related to cardiovascular diseases, depression, cataract and some types of cancer. Evidences of a relation between exposure to mercury and an increase in the risk of neurological disorders, but not of cardiovascular diseases, were also found. Given the importance of fish consumption, its possible risks and the lack of Brazilian studies on the topic, it is important to conduct more longitudinal studies that assess both the benefits and risks of fish consumption for the human health. We also emphasize the need for policies to reduce exposure of fish and seafood to mercury and other contaminants.Indexing terms: Fishs. Food consumption. Health. Risk. R E S U M O I N T R O D U C T I O NFishes are rich in essential fatty acids, as well as in iron, vitamin B 12 and calcium. Fish consumption is recommended by The American Cancer Society and the American Heart Association (AHA) at least two times a week 1,2 .Brazil has great potential for fish farming due to its extensive maritime coast and continental waters, together with the possibility of consumption of great variety of species 2 . Not with standing that, fish consumption in Brazil dropped considerably in recent years 3,4 .Some studies have demonstrated the health benefits of fish consumption thanks to the correlation between omega-3 fatty acids and a decrease in the incidence of coronary heart diseases 5-10 , depression 11,12 , stroke 13 , blood pressure 5,14 , glycemic index 14 , triglycerides 5 , cancer 15,16 and others. On the other hand, researches could also quantify levels of fish contamination in 17 fish and check possible risks linked to its consumption, such as contamination by heavy metals, organochlorine pollutants and dioxins [17][18][19][20] .With the incentive to fish consumption and a current discussion on its benefits and risks 21,22 , seconded by a lack of scientific studies with clear conclusions about contamination, it is imperative that literature about risks and benefits of fish consumption is reviewed, especially in Brazil. Moreover, in the searches performed, no critical reviews on the subject were found. Therefore, this article aimed at identifying and discussing scientific evidences on the benefits and risks of fish consumption for the human health. M E T H O D SThe study was designed to answer a guiding question: what are the scientific evidences on benefits and risks of fish consumption for the human health? The methodo...
