Is Diet the only cause of CHD?

Extracts from this document...


Is Diet the only cause of CHD? Coronary Heart Disease (CHD) is not a single disease, but it's a complex of diseases. There are many factors affecting Coronary heart disease (CHD). The main cause of coronary heart disease is a narrowing of the coronary arteries that supply oxygen and nutrients to the heart muscle. Narrowing of coronary arteries is mainly caused due to atherosclerosis, which is the thickening and hardening of the inside walls of arteries. The word atherosclerosis is of Greek origin and literally means focal accumulation of lipid. Hardening of arteries mainly occurs at old age. Diet is not the only cause of Coronary heart disease. When we eat foods rich in saturated fat and cholesterol, cholesterol is then deposited in our arteries in the form of plaque or atheromas that cause blockages. Heart attack occurs, when such blockages become severe or if a clot forms that cannot get past the plaque and the heart is starved of blood. Many factors affecting Coronary heart disease that results through diet are obesity, diabetes, high cholesterol, high blood pressure and high fat diet. The most common cause atherosclerosis is a build up of fatty materials within the walls of the arteries throughout the body, most importantly in the coronary arteries. ...read more.


Passive smoking is also believed to be responsible for many deaths from cardiovascular disease. Exposure to other people's smoke increases the risk of heart disease even for non-smokers. Other risk factors apart from diet, smoking and high blood pressure are diabetes, heredity, age, gender and ethnicity. Diabetes is a life long disease in which sugar (glucose) remains in the blood rather than entering in the body's cell to be used for energy. People who have diabetes are at increased risk for many serious heart problems, including hardening of arteries (atherosclerosis). About three-quarters of people with diabetes die of some form of heart or blood vessel disease. Researchers have identified more than 250 genes that may play a role in Coronary heart disease. The genetic mutation leads to heart disease by causing high blood pressure, high blood levels of "bad cholesterol" and diabetes, all risk factors for heart disease. Children of parents with heart disease, who carried the mutation died in their early fifties from coronary artery disease that resulted in heart attacks and heart failure. Persons with effects of Coronary heart disease often have siblings, parents and even spouses who also have Coronary heart disease. Most people with a strong family history of heart disease have one or more other risk factors. ...read more.


It can also make diabetes more likely to develop. Many obese and overweight people may have difficulty losing weight. But by losing even as few as 10 pounds, you can lower your heart disease risk. Exercise is one of the best ways to help maintain a healthy weight. Regular exercise helps in maintaining a healthy heart. Individual response to stress may be a contributing factor. Some scientists have noted a relationship between coronary heart disease risk and stress in a person's life. Drinking too much alcohol can raise blood pressure, cause heart failure and lead to stroke. It can contribute to high triglycerides, cancer and other diseases. A person who has all three main risk factors, high blood cholesterol, high blood pressure and smoking, is eight times more likely to develop heart disease than someone who has none. As there are many factors affecting Coronary heart disease (CHD), we cannot say that diet is the only cause of Coronary heart disease. But we can say that diet is the main cause of Coronary heart disease among all other factors. Different factors have their own effect on our body. Many factors causing Coronary heart disease like obesity, diabetes, hypertension etc are indirectly related to diet. An individual can have control on his own diet, quit smoking but certain factors like ethnic origin, inheritance are inevitable. Regular exercise and proper intake of diet can help us to avoid such heart diseases. 1 1 ...read more.
