TEXT A. HEART DISEASES
Its unfortunate that many people suffer from health disorders that are the result of overeating in food or unwise choice of diet. An unbalanced diet, e.g. containing too much fat or sugar, can result in a variety of nutritional disorders, including: heart diseases, obesity, eating disorders, tooth decay and gum disease.
To work normally, the heart muscle needs a supply of oxygen from blood in the coronary arteries so that it can pump blood through vessels to all parts of the body.
If one of the coronary arteries becomes blocked with fatty deposits, the blood carrying oxygen cannot reach the heart. This is called angina.
If there is a sudden and complete blockage in the arteries, caused by a blood clot (thrombus), no blood gets through, and a person suffers a heart attack. Doctors call a heart attack a coronary thrombosis (because of the blood clot) or a myocardial infarction (which means death of the heart muscle).
Choice of food and heart diseases
Researches have shown that our diet, especially the amount and type of fat we eat, can increase the risk of coronary heart diseases. Foods that are rich in saturated fatty acids may raise the level of cholesterol in the blood. Cholesterol is found in some foods, and is also made in the body by the liver, mainly from saturated fatty acids in food. If cholesterol is oxidized (combines with oxygen circulating in the blood), it can be deposited in the linings of the coronary arteries, which start to become blocked.
Antioxidants which are naturally found in foods, especially vitamin E, vitamin C, β-carotene, and selenium help to stop cholesterol combining with oxygen.
To prevent heart disease people should:
1. eat various foods, fruit, vegetables, and salads.
2. eat less high-fat and sweet food.
3. take exercise and be active as this strengthens the heart.
