Omega-3s from Krill Oil May Reduce Fasting Blood Glucose Levels
High fasting blood glucose levels can lead to diabetes and cardiovascular disease. A recent study suggests that krill-derived omega-3 fatty acids may help reduce fasting blood glucose levels.
Participants in the study included 36 healthy men and women between the ages of 18 and 70 with fasting triglycerides of 1.3 to 4.0 millimols per liter (mmol/l). Over the course of eight weeks, they were given either krill oil capsules containing 4654 mg of omega-3s, lean or fatty fish containing 4103 mg of omega-3s, or a control of high-oleic sunflower oil.
At the conclusion of the study, the researchers found that both the krill oil and the fish increased blood levels of omega-3 fatty acids. Additionally, the krill oil was associated with reduced fasting glucose levels. They also noted that the krill oil was associated with a change in the peripheral blood mononuclear cell mRNA expression of genes involved in glucose and cholesterol metabolism, while the fish was associated with altered expression of four genes and the sunflower oil down-regulated 16 genes.
Researchers from the University of Oslo led the study. It was published online ahead of print on March 21, 2018, in the Journal of Nutritional Science.
Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. For people who don’t like fish, consider taking a daily high-quality non-fish supplement that has been tested for purity and potency.
