Many of us have long been told that saturated fat, the type found in meat, butter and cheese, causes heart disease. But a large and exhaustive new analysis by a team of international scientists found no evidence that eating saturated fat increased heart attacks and other cardiac events.
.
The new findings are part of a growing body of research that has challenged the accepted wisdom that saturated fat is inherently bad for you and will continue the debate about what foods are best to eat.
.
For decades, health officials have urged the public to avoid saturated fat as much as possible, saying it should be replaced with the unsaturated fats in foods like nuts, fish, seeds and vegetable oils.
.
But the new research, published on Monday in the journal Annals of Internal Medicine, did not find that people who ate higher levels of saturated fat had more heart disease than those who ate less. Nor did it find less disease in those eating higher amounts of unsaturated fat, including monounsaturated fat like olive oil or polyunsaturated fat like corn oil.
.
"My take on this would be that it's not saturated fat that we should worry about" in our diets, said Dr. Rajiv Chowdhury, the lead author of the new study and a cardiovascular epidemiologist in the department of public health and primary care at Cambridge University.
.
But Dr. Frank Hu, a professor of nutrition and epidemiology at the Harvard School of Public Health, said the findings should not be taken as "a green light" to eat more steak, butter and other foods rich in saturated fat. He said that looking at individual fats and other nutrient groups in isolation could be misleading, because when people cut down on fats they tend to eat more bread, cold cereal and other refined carbohydrates that can also be bad for cardiovascular health.
