Brief Summary

The knowledge of the health effects of CLA on the human body is limited. However, CLA supplements are sold over the counter in several countries and various techniques are used to increase the content of CLA in food. The CLARINeT study will be performed to investigate the effect of CLA on blood lipoproteins, inflammatory markers, blood pressure and insulin status in human volunteers relative to industrial trans fatty acids and to oleic acid.
