Other studies suggest that foods which are high in minerals like potassium, such as bananas and potatoes, may also play a role in lowering blood pressure. Maintaining a healthy weight People who are obese run an increased risk of heart disease. Heart experts say physical activity can reduce the risk of high blood pressure caused by constricted arteries. The way the fat is deposited around the body can also affect the risk. Men are more likely to be apple-shaped than women.
Blood clots Blood clots can block or stem the blood flow, causing a heart attack.
So foods which contain chemicals which prevent blood clotting can protect against heart disease. These include naturally oily fish, such as mackerel, sardines and salmon. Fibre Fibre has been shown to reduce blood cholesterol levels and may therefore reduce the risk of heart disease. Foods high in fibre include cereal crops such as oats, pasta, bread and potatoes.
