Fish oil is available in both food and supplement form, and the Food and Drug Administration recognizes it as appropriate for the treatment of high triglycerides. Fish oil promotes health because it contains omega-3 fatty acids, and it is known to provide a range of health benefits for the brain and cardiovascular system.
Omega -3 Fish Oil for Depression
Omega-3 fish oils can promote mental health by treating depression. In a review of 13 studies, researchers for a 2017 publication of Translational Psychiatry found that on the whole, fish oil reduces symptoms associated with major depressive disorder.
Attention Deficit Disorder Improved with Fish Oil
The research also supports the use of omega-3 fish oil for children with ADHD. A 2014 report in Clinical Psychology Review assessed the results of 16 studies that analyzed the relationship between omega-3 supplements and ADHD symptoms, and assessment results indicated that these supplements significantly decreased levels of hyperactivity.
Omega-3 Fish Oil and Heart Health
Omega-3 fish oil can improve heart health by lowering both triglycerides and blood pressure. A 2014 study in the International Journal of Cardiology found that an omega-3 supplement lowered triglyceride levels more effectively than a placebo did. A 2002 review published in the Journal of Hypertension analyzed the results of 36 studies and found that high doses of fish oil tended to reduce blood pressure levels, particularly among people over the age of 45 and those with hypertension.
Fish Oil for Increased Metabolism
Fish oil has been shown to elevate metabolism in older women. A 2015 study in the journal PLOS ONE found that women who took fish oil daily for 12 weeks experienced an increase in resting metabolism and fat burn. They also burned more calories and fat during exercise. No such increases in metabolism were seen in women who consumed an olive oil placebo.
Fish Oil Linked to Rheumatoid Arthritis Relief
Omega-3 fish oil might provide relief to patients with rheumatoid arthritis. A 2016 study in the Annals of the Rheumatic Diseases found that patients with rheumatoid arthritis experienced less pain after three months of treatment when they took omega-3 supplements.
Cognitive Functioning Benefits Associated with Fish Oil
Regular intake of omega-3 fish oil could slow age-related cognitive decline. A study in a 2015 publication of Alzheimer’s & Dementia found that older adults who consumed fish oil supplements scored lower on an assessment of Alzheimer’s Disease and higher on a test of mental state when compared to those who didn’t consume fish oil. Fish oil consumers also demonstrated greater volume in the hippocampus, an area of the brain associated with memory.
Omega-3 fish oil can improve cognitive functioning and also facilitate mental and physical wellbeing. The research suggests that if offers a variety of benefits, and it can be useful for many people.
