NCT02350595

Brief Summary

The potential health effects of high intake of lean or fatty fish will be investigated in overweight or obese adults. Participants consume 750g/week of fillets of fish for 8 weeks. Hypothesis: High intake of fatty or lean fish will beneficially affect glucose regulation and the immune system.
