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.
