Omega-3 fatty acids from fish oils might help some people with heart disease.
Potassium is essential for people with high blood pressure as it is one dietary factor that exerts a beneficial effect.
Potassium lowers blood pressure and it also protects against stroke and damage to blood vessels when blood pressure is high.
Studies have shown that groups of people who eat low-potassium diets have an increased incidence of high blood pressure and heart disease. Diets high in potassium and low in sodium can lower blood pressure.
3.5 g of potassium per day is associated with lower blood pressure and fewer deaths from strokes. In order to get this level of potassium, eat the five or more servings of fruit and vegetables a day recommended in the Eat for Life guidelines.
The average adult needs no more than several hundred milligrams of sodium a day.
Since there is no easy way to measure salt sensitivity, it makes sense for all of us to reduce our salt intake as a means of protecting ourselves against high blood pressure.
If you already have high blood pressure, reducing the amount of sodium you eat may help lower your blood pressure.
