Some biochemical studies on trans fatty acid-containing diet

trans fatty acids (TFA's) are unsaturated fatty acid which have one or more double bond, they are present naturally and most of it is artificial, fried, baked food and margarine are major sources of TFA, there are several biological effects of TFAs on body health, various study showed that dietary TFA associated with various health disorders such as Diabetes, cardiovascular disease (CVD), Obesity, breast cancer, prostatic cancer infertility, and coronary artery disease (CAD). The World Health Organization (WHO) in 2015 encourages eliminations of trans fatty acids. The diet which related to non-communicable diseases include TFA should be eliminated, WHO's European Food and Nutrition Action Plan 2015–2020 suggested that TFAs should be less than 1% of the daily energy intake include natural origin. So the aim of this review, to know more than about trans acids, their nature, sources, and their different effect on health and how can analysis it.
