Diets rich in omega-3 fatty acids may help lower blood pressure in young, healthy adults
Healthy young people may be able to help prevent the onset of high blood pressure by eating diets rich in omega-3 fatty acids, according to a preliminary study presented at the American Heart Association's Scientific Sessions 2016.
Omega-3 fatty acids are essential fats, mostly found in fish and some types of plant oils. Researchers studied 2,036 young, healthy adults by measuring the amount of omega-3 fatty acids in their blood and recording their blood pressure measurements. They divided people into four groups, from the quarter with the highest amount of omega-3 fatty acids in their blood to the quarter with the lowest.
They found adults in the highest quarter had about 4 mm Hg lower systolic and 2 mm Hg lower diastolic blood pressure compared to those with the least omega-3 fatty acids in their blood.
In general, the higher the omega-3 fatty acids in the blood meant lower both systolic and diastolic blood pressure. This suggests promoting diets rich in omega-3 foods could become a strategy to prevent high blood pressure.
