Krill oil helps heart health in mice

A study published in the journal Nutrition and Metabolism on July 13th indicates that krill oil (which is rich in omega-3 fatty acids) may promote heart health and assist in weight management. The study was conducted on mice by Italian and Australian researchers. The mice were placed on a high-fat diet and then given supplements.

After 8 weeks, the mice had improved cholesterol and triglyceride levels and other health indicators. One researcher noted that krill oil, due to its omega-3 content, had the potential to support metabolic health which can be harmed by conditions like obesity.

The study examined the effects of omega-3 fatty acids on endocannabinoids, which can affect appetite, fat accumulation and other factors. The high-fat diet increased endocannabinoid activity in the mice studied, and the effects decreased after the mice consumed the krill oil. The favorable results have lead to further study, this time with human participants.

The CDC notes that unsaturated fats (including omega-3 fats) may boost health better than saturated fats. In addition to krill oil, good sources of unsaturated fats include fish oil, soybean or canola oil and walnuts. omega-3 fatty acids are frequently available through fish oil or other nutrient supplements.
