Trans Fatty Acids, does Exist Safety Dosage?

Igor Brandão and Rafael Longhi

Recent data regarding Trans Fatty Acids (TFAs) have implicated this lipid as being particularly deleterious to human health. TFAs are unsaturated fatty acids that contain at least one non conjugated double bond in the trans configuration, resulting in a more linear shape. The presence of a trans double bond in a fatty acid chain results in a smaller bond angle, or kink, than in a cis double bond, resulting in a fatty acid chain conformation that is more similar to a saturated fatty acid than to an unsaturated fatty acid. Several studies have identified an association between trans-fat intake and a risk of neurodiseases, cardiometabolic disease and pro-inflammatory effects. It focuses on a series of recent studies that have supporting the pathogenic role through human or animal experiments in vitro or in vivo. Overall, the findings of this short communication suggest that fat composition is more important than the quantity of fat consumed in terms of dietary cis and trans fatty acids.
