Diets rich in omega-3 fatty acids protect the liver from damage caused by obesity and the insulin resistance it provokes. This research should give doctors and nutritionists valuable information when recommending weight-loss diets and help explain why some obese patients are more likely to suffer some complications associated with obesity. Omega-3 fatty acids can be found in canola oil and fish.

Eating fatty fish and marine omega-3 fatty acids, which are found in fish oil, seems to protect men from heart failure, according to one of the largest studies to investigate the association.

The American Heart Association recommends that people consume at least 5 percent to 10 percent of calories from omega-6 fatty acids. It's recommended that the omega-6 comes from foods, not supplements. Replacing saturated fats with polyunsaturated fatty acids may lower the risk for heart disease. Higher intakes of omega-6 may improve insulin resistance, reduce diabetes risk and lower blood pressure.

Semi-palmated sandpipers migrate over thousands of miles, but how do they build up for the ultramarathon? By simply eating a diet rich in omega-3 fatty acids according to a new study. Researchers fed sedentary bobwhite quails that don't exercise a diet rich in omega-3 fatty acids and found that the birds' fitness improved by up to 90 percent. A diet of omega-3 fatty acids can make birds fit by simply eating.

Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken.

Omega-3 fatty acids ease psychological distress and depressive symptoms often suffered by menopausal and perimenopausal women, according to new research. The study presents the first evidence that omega-3 supplements are effective for treating common menopause-related mental health problems.

The roe of hake, lumpsucker and salmon is the best dietary source of omega-3, according to a new study. The scientists analyzed the eggs, or roe, of 15 marine animals, and found all of these contained high levels of these fatty acids, which are essential to the human body.

Many people now take fish oil in supplements or foods, convinced of the benefits shown in a number of medical studies. However, there are also dangers associated with fish oils because the fish which are high in omega-3 fatty acids, such as mackerel, trout, tuna and salmon, often accumulate toxic substances in them because of their position in the food chain.

This study extends the existing literature by finding a strong association between low omega--3 fatty acids and depression in outpatients with stable coronary heart disease, a population distinct from sicker, hospitalized patients with acute coronary syndrome.

The typical American diet often lacks omega-3 fatty acids despite clinical research that shows their potential human health benefits. Now researchers have found a way to grow these compounds using a byproduct of the emerging biodiesel industry.
