The American Heart Association and other groups have said for many years that people could reduce the chance of suffering a heart attack by eating less of the foods rich in cholesterol. These include such foods as meats, milk products and eggs. The Heart Association noted a number of studies which show that nations where people eat a lot of high cholesterol foods have a higher number of deaths from heart disease.
However, the new report disagrees. It was made by the Food and Nutrition Board of the United States National Academy of Sciences. The new report by a team of 15 scientists said there is no evidence to link cholesterol in food directly to heart disease. It noted seven major studies involving people whose diet was changed to include only foods low in cholesterol. The studies found only a very small reduction in the number of heart attacks and there was no reduction in the number of heart attack deaths.
Other studies have shown similar results. They found that a change to low cholesterol foods will have only a minor effect on the amount of cholesterol in a persons blood and only a minor effect on the number of deaths.
Medical scientists hope that two huge new studies may settle the cholesterol dispute. The tests are designed to learn if low cholesterol foods or anticholesterol drugs, or both, can reduce the amount of the substance in the blood and reduce the chance of a heart attack. The two new studies will be finished in the next year or two.
