The best way to prevent having a heart attack is to make changes to your lifestyle.
There are 3 main steps you can take to help prevent a heart attack:
- eat a healthy, balanced diet
- avoid smoking
- try to keep your blood pressure at a healthy level
To lower the risk of a heart attack you should eat 2 to 4 portions of oily fish a week. Oily fish contains a type of fatty acid known as omega-3. This can help lower your cholesterol levels.
Good sources of omega-3 include:
Never take a food supplement without first consulting your GP. Some supplements, such as beta-carotene, could be harmful to you.
It's also recommended that you eat a Mediterranean-style diet.
This means eating more:
You are also advised to eat less meat. Replace butter and cheese with products based on vegetable and plant oil, such as olive oil.
Foods to avoid
If you eat a diet high in fat, your risk of having a heart attack increases.
An unhealthy, high fat diet will make the hardening of your arteries worse. This is because fatty foods contain cholesterol.
There are also 2 types of fat – saturated and unsaturated.
Avoid foods containing high levels of saturated fat. They increase levels of bad cholesterol in your blood. This 'bad cholesterol' is known as low-density lipoprotein (LDL).
Foods high in saturated fat include:
- meat pies
- sausages and fatty cuts of meat
- ghee (a type of butter often used in Indian cooking)
- hard cheese
- cakes and biscuits
- foods that contain coconut or palm oil
Eating a small amount of unsaturated fat will increase the level of good cholesterol. This 'good cholesterol' is called high-density lipoprotein (HDL). It can help reduce any blockage in your arteries.
Foods high in unsaturated fat include:
- oily fish
- nuts and seeds
- sunflower, rapeseed and olive oil
Smoking is a major risk factor for heart attacks.
This is because it causes:
- atherosclerosis (build up of plague in arteries)
- raised blood pressure
