Several polyunsaturated fatty acids are considered to have beneficial health effects, while saturated fatty acids and industrial trans fatty acids (TFAs) are linked to negative health consequences. Given the increased formation of TFAs during heating, many studies already investigated compositional changes in oils after prolonged heating or at extremely high temperatures. In contrast, our aim was ...

Abstract:
... The beneficial effects of n-3 LCP (Long Chain PUFA) on human health are widely known. Humans are rather inefficient in synthetizing n-3 LCP, thus, these compounds should be supplemented in the diet. However, most Western human diets have unbalanced n-6/n-3 ratios resulting from eating habits and the fact that fish sources (rich in n-3 LCPs) are not sufficient (worldwide deficit ~ 347,956 t/y) to m ...
