The hypothesis that saturated fats cause arterial inflammation and result in higher risk of heart attacks has no basis in science. But repeat anything enough times and people start to believe it to be true. Inflammation is what results in heart disease and there is a great deal known about sources for that inflammation which is based on the consumption of animal protein in the form of meat and dairy products. Even worse are meats that have nitrates added as with salami, luncheon meats, bacon, and sausage. Many people are snacking on beef jerky that is high in sodium and nitrates based on a belief that it is keto and therefore good.
