Disease Risk Reduction and Omega-3 Rich Rainbow Trout (Fish for Health)

Disease Risk Reduction and n-3 Rich Rainbow Trout (Fish for Health)

The purpose of this study is to determine how eating fish raised to have different levels of omega-3 fatty acids will reduce cardiovascular risk markers in people with elevated cardiovascular risk.

Consumption of fish high in long chain omega-3 fatty acids (LCn3) is associated with reduction of cardiovascular disease (CVD) risk. CVD is a major cause of death in the United States. The current obesity epidemic contributes significantly to elevated CVD risk by increasing inflammation and platelet dysfunction. Prevention of CVD is a public health goal and comprises several avenues of action, of which inclusion of LCn3-rich fish in the diet may be one of the most effective.

Obese participants will participate in a double blind, randomized, cross-over designed trial in which they will consume twice-weekly a prepared meal containing diploid (2N) farmed rainbow trout, triploid (3N) farmed rainbow trout containing higher levels of LCn3, or tilapia, a low LCn3 fish.
