Contributory factors to heart disease

Extracts from this document...

Introduction

Contributory factors to heart disease Diet is not the only factor that causes heart disease; lifestyle is also a very big factor. Smoking deprives the blood of oxygen and also narrows the blood vessels. Smoking dramatically increases the risk of developing heart disease, lung cancer and many other diseases. These diseases are not always fatal but can seriously affect your quality of life. If a person smokes they are more likely to die before they retire. " Smoking doubles your risk of dying from heart disease. Each year 35,000 British smokers die from heart disease." (Flora project for heart disease.) Taking more exercise will help prevent C.H.D. as it has a direct link to obesity. When a person is overweight the body and the heart have to work harder. A lack of exercise can increase the chances of C.H.D. ...read more.

"It is thought that for people likely to develop high blood pressure a high salt intake is a contributory factor to C.H.D." (The science of food.)

Conclusion

Try and cut the foods out in other parts of the diet." (Dr. M. Lagan) I think doctor Lagan means that you should have the required amount of calcium in the diet, to cut the fat from meat, chocolate and ice cream. You don't have to become a vegan. Just to eat lean meat, chicken or cut out excess fat trough the different methods of cooking like grilling your bacon. Simple things like this can help reduce your cholesterol and chances of C.H.D. the required amount of fat per person vary upon the person's age, sex, height and occupation. Heart disease can be prevented if the person really wants to. Combine a healthy diet with a healthy lifestyle and there should be no problems. That is providing you stick to it and not just do it now and again. ?? ?? ?? ?? Gr�inne N� Louis 12-59 ...read more.
