The Role Of Diet In The Aetiology Of Coronary Heart Disease

1.0 Summary

The report to discusses the role of diet in the aetiology of Coronary Heart Disease (CHD) and critically assesses the measures the government has taken in trying to reduce death rates from CHD through dietary measures.

Two of the health campaigns the government has been partially successful in are:

• 5-a-day fruit and veg campaign
• 6g of salt campaign

There is a lot of information available from the government but some of it is incomplete and difficult to access unless you are interested in the subject or you actually require the information because you are already at risk.

2.0 Introduction

The purpose of the report is to Discuss the role of diet in the aetiology of Coronary Heart Disease (CHD) and critically comment on the approach that the government has taken in trying to reduce death rates from CHD through dietary measures.

Aetiology is the study of factors of causation or those associated with the causation of disease or abnormal body states (biology-online 2006)

This report will focus on:

• Coronary Heart Disease
• Fats in the diet
• The Dietary Fat Hypothesis
• Salt in the diet
• Antioxidants
• Soluble dietary fibre
• Alcohol and its Effect on Cholesterol
• Government initiatives

3.0 Coronary Heart Disease (CHD)

CHD is caused when the coronary arteries, which supply blood to the heart, become narrower because of the build-up of fatty deposits inside them. This 'furring up' of the arteries is called atherosclerosis.

In time the artery may become so narrow that not enough blood gets through to the heart. This means the heart muscle doesn't get all the oxygen it needs, which is called angina.

If the narrowed artery becomes blocked by a blood clot, this causes a heart attack. (FSA. 2006)

4.0 Fats in the Diet

Fats are insoluble in water, the body uses fats in the formation of cell membranes particularly in nerve cells, it is used transport small amounts of fat soluble vitamins A, D, E, K....
