High DHA Omega-3s May Boost Immunity in Obese People
People with obesity often have a weakened immune system, primarily due to an increase in inflammation. A recent study suggests that taking a daily supplement of high DHA fish oil concentrate may help support a healthy immune system in middle-aged, obese adults.
Participants in the study included 34 obese men and women who were given one gram per day for 12 weeks of either fish oil concentrate, high DHA fish oil concentrate, or olive oil as a control.
At the conclusion of the study, both fish oil groups had reductions in the percentage of circulating memory and plasma B cells. B cells are white blood cells that help with antibody production. When they examined the high DHA fish oil on its own, the researchers noted improvements in secretion of pro-inflammatory molecules including tumor necrosis factor-alpha and cytokine interleukin-10, an anti-inflammatory.
Researchers from East Carolina University led the study. It was published in the March 2018 issue of The Journal of Nutritional Biochemistry.
There are two types of omega-3s: DPA and EPA. Omega-3s have been linked to a number of health benefits, including improved mood, improved joint mobility, reducing the risk of age related macular degeneration, and aiding your immune system.
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.
