RESUMO

Introduction and Aims: dietary Tran's fatty acids [TFA] comes mostly from the industrial hydrogenation of unsaturated vegetable oils. TFA also are formed during the natural bacterial hydrogenation of unsaturated fatty acids that occurs in the rumen of polygastric ruminants such as cattle, sheep, and goats. The epidemiologic evidences suggest that the intake of Tran's fatty acid may be associated with increased risk of cardiovascular diseases [CVD] such as atherosclerosis or chronic heart disease [CHD]. The purpose of the current study is better understanding of effects of TFA on cardiovascular disease. So, the available evidences from studies were reviewed


Materials and Methods: a complete search was performed about the association of TFA intake with risk of CVD in databases electronic such as ISI Web of science and PubMed and also in SID from1993 to 2014


Results: the results of most studies have indicated a significant direct association between the TFA intake and risk of CVD. Also, increasing of TFA intake was related with increased risk of diabetes, systemic inflammation, decreased membrane fluidity, increased serum lipid levels and inflammatory markers


Conclusion: the most evidence for association between the intake of TFA and cardiovascular diseases were related to TFA from hydrogenated vegetable oils and information about the effects of TFA from ruminant was inconsistent. It is necessary performing studies about the effects of rTFA [ruminant Tran's fatty acid] on risk of CVD and banning the use of these fatty acids in the food industry
