The saturated fat found mainly in meat and dairy products has a bad reputation, but a new analysis of published studies finds no clear link between people's intake of saturated fat and their risk of developing heart disease.

In the new analysis, which combined the results of 21 previous studies, researchers found no clear evidence that higher saturated fat intakes led to higher risks of heart disease or stroke.

A number of studies have linked the so-called Western diet to greater heart disease risks; that diet pattern is defined as one high in red meats and saturated fats -- but it is also high in sweets and other refined carbohydrates like white bread.
