Decreased Hunger Levels: In a study of 232 overweight and obese volunteers in the journal Appetite, researchers put obese and overweight subjects who were in the last two weeks of an eight-week weight-loss plan on either high or low doses of omega-3s. After 10 weeks, adiponectin-a healthy protein secreted by fat cells that reduces inflammation-rose significantly, while tumor necrosis factor, a protein involved in triggering systemic inflammation, declined significantly.Ģ. In a second European Journal of Clinical Nutritionstudy, 17 healthy young adults were put on a 10-week diet of reduced omega-6s and increased omega-3s. "A high concentration of CRP was significantly associated with obesity." But omega-3s can overcome inflammation. In the study, BMI and body fat increased significantly as CRP levels increased. Their blood was tested for C- reactive protein (CRP), a marker of inflammation. Reduced Inflammation: In a study in Circulation Journal, researchers looked at the BMI, body fat, and weight gain in 1,053 residents over 40 years of age. What are some health benefits of omega-3 fatty acids?ġ. There are three main types of omega-3s-eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA)-and one additional omega-3 that's recently been found to also convey health benefits: docosapentaenoic acid (DPA).ĭHA, EPA, and DHA are found in fish and other seafood, although DPA is found in much lower concentrations than DHA and EPA, according to a review in Lipid Technology.ĪLA is found in plants, plant-based oils, and animal products who feed on an ALA-rich diet.
They're called "essential" fatty acids because the human body cannot produce them naturally, so the only way we can consume them is through our diet. Omega-3 fatty acids are long chains of fats found naturally in many of our healthiest foods, especially wild salmon, which has more than 1,500 milligrams in a 3-ounce portion.
