SATURATED FAT IMPROVES THE LIPID PROFILE; CARBS AND POLYUNSATURATED FATS WORSEN IT ~ so are you still denying yourself the goodness of sour cream, butter, full-fat milk and yogurt (not the kind with added sugar)? First we had the marvelous news that full-fat milk and other dairy products lower blood pressure and reduce the risk of heart disease, stroke, and cancer. How can this be? It turns out that saturated fats don’t increase the small, dense LDL cholesterol, easily oxidized and thus dangerous. They increase the big. “fluffy” cholesterol particles, considered benign and possibly even protective. “In addition to raising LDL cholesterol, saturated fat also increases high-density lipoprotein, or HDL, the so-called good cholesterol. And the LDL that it raises is a subtype of big, fluffy particles that are generally benign. Doctors refer to a preponderance of these particles as LDL pattern A. The smaller, more artery-clogging particles are increased not by saturated fat, but by sugary foods and an excess of carbohydrates, Dr. Chowdhury said. “It’s the high carbohydrate or sugary diet that should be the focus of dietary guidelines,” he said. “If anything is driving your low-density lipoproteins in a more adverse way, it’s carbohydrates.” When the researchers looked at fatty acids in the bloodstream, for example, they found that margaric acid, a saturated fat in milk and dairy products, was associated with lower cardiovascular risk. Two types of omega-3 fatty acids, the polyunsaturated fats found in fish, were also protective. But a number of the omega-6 polyunsaturated fatty acids, commonly found in vegetable oils and processed foods, may pose risks, the findings suggested.” I dont like the image chosen by the NY Times to go with this article. Whats wrong with it? I think I see bacon, which is carcinogenic, like all processed and grilled meats; and of course the bun is pure empty-calorie carbohydrates. Eat your (preferably home-cooked) hamburger with a salad.
