Abstract: This systematic review without date restrictions is about the physiological effects of conjugated linoleic acid on regression of carcinogenesis, oxidative stress, glucose and lipid metabolism and change in body composition. The objective was to establish the historical aspect of research advances regarding conjugated linoleic acid, considering original articles reporting work on animals, cell cultures and humans. Regarding the researches on the anticarcinogenic effect of conjugated linoleic acid, innumerous evidences were found in this respect, especially in the regression of mammary and colon tumors induced by both isomers which act distinctively. The researchers devoted considerable effort to reinvestigate the antioxidant properties of conjugated linoleic acid. Although the antioxidant properties have been investigated, pro-oxidant effect has been identified leading to oxidative stress in humans. Few studies demonstrated significant beneficial effects of conjugated linoleic acid on the metabolism of lipids and glucose and on the reduction of body fat, especially in humans. Studies with adverse effects were also identified. There is strong indication that the action of this conjugated fatty acid on a class of transition factors - the peroxisome proliferator-activated receptor - and on the consequent modulation of gene expression can be the fundamental explanation of its physiological effects. The most recent studies reinforce the nutrigenomic concept, that is, the modulation of gene expression induced by compounds present in the foods consumed by humans. This current scenario stimulates the scientific community to seek a consensus on the effects of conjugated linoleic acid in humans, since it is naturally found in some foods; when these foods are consumed regularly and in appropriate amounts, they could help prevent and control innumerous chronic diseases.
