Omega-3 fatty acids are vital to proper cell functioning and play an important role in various bodily systems. Some food sources include fatty fish, seaweed, flaxseeds, and chia seeds. Omega-3s are a type of essential fatty acid, meaning people must obtain them from their diet.
There are three main types of omega-3 fatty acids: DHA, EPA, and ALA. Fish and seafood sources of omega-3 tend to be higher in DHA and EPA, while plant sources are typically higher in ALA. Eating a variety of omega-3 foods is important for optimal health.
Omega-3s Can Fight Inflammation
Inflammation is a natural response to infections and damage in your body. Long-term inflammation can contribute to almost every chronic Western illness, including heart disease and cancer. Notably, omega-3 fatty acids can reduce the production of molecules and substances linked to inflammation, such as inflammatory eicosanoids and cytokines.
Omega-3s Can Fight Autoimmune Diseases
In autoimmune diseases, your immune system mistakes healthy cells for foreign cells and starts attacking them. Type 1 diabetes is one prime example, in which your immune system attacks the insulin-producing cells in your pancreas. Omega-3s can combat some of these diseases and may be especially important during early life.
Omega-3s Can Fight Age-Related Mental Decline and Alzheimer’s Disease
A decline in brain function is one of the unavoidable consequences of aging. Several studies link higher omega-3 intake to decreased age-related mental decline and a reduced risk of Alzheimer’s disease. One review of controlled studies suggests that omega-3 supplements may be beneficial at disease onset when the symptoms of AD are very mild. Keep in mind that more research is needed on omega-3s and brain health.
Omega-3s Can Improve Risk Factors for Heart Disease
Heart attacks and strokes are the world’s leading causes of death. Decades ago, researchers observed that fish-eating communities had very low rates of these diseases. This was later linked to omega-3 consumption. Since then, omega-3 fatty acids have been tied to numerous benefits for heart health.
The American Heart Association recommends consumption of two servings of fish per week for persons with no history of coronary heart disease and at least one serving of fish daily for those with known coronary heart disease. Approximately 1 g/day of eicosapentaenoic acid plus docosahexaenoic acid is recommended for cardioprotection. Higher dosages of omega-3 fatty acids are required to reduce elevated triglyceride levels (2-4 g/day). Modest decreases in blood pressure occur with significantly higher dosages of omega-3 fatty acids.
