7 surprising benefits of omega-3s, according to a dietitian

If you’re not eating fish at least twice a week — or taking a fish oil supplement — you might be missing out on one of the most powerful nutrients for your health: omega-3 fatty acids. Found mainly in fatty fish like salmon, these essential fats do far more than reduce inflammation — they support nearly every system in the body.

Recent studies show that most adults consume only half the recommended amount of omega-3s, missing out on key benefits such as:

Joint Support:
Omega-3s can help reduce inflammation and pain in people with arthritis, protecting cartilage and improving mobility.

Heart & Vascular Health:
They help lower triglycerides, improve blood flow, and raise “good” HDL cholesterol — reducing the risk of heart disease and stroke.

Eye Health:
Omega-3s may relieve dry eye symptoms and lower the risk of age-related macular degeneration by protecting retinal cells.

Blood Sugar Balance:
By improving insulin sensitivity, these fats may help stabilize blood sugar and reduce the risk of type 2 diabetes.

Weight & Metabolism:
Omega-3s can reduce belly fat and inflammation while regulating hormones tied to appetite and fat storage.

Stronger Immunity:
They may enhance immune response and help the body fight infections more effectively.

Brain Function & Mood:
DHA supports memory, learning, and focus. Some studies suggest omega-3s may also reduce symptoms of depression and anxiety.

Experts recommend getting omega-3s from fatty fish (like salmon, mackerel, and sardines) or through fish oil supplements if your diet falls short.
