Chylomicrons carry fats from the intesine to the body and the liver. Vldl and ldl leak fats as they carry them into the blood vessels (lazy cholesterol) Hdl (healthy or happy) cleans up the fats that the ldl or vldl has dropped. Doctors measure blood lipids to assess heart disease risk. Triglycerides, they measure the # of vldl paricles. Ldl-cholesterol, they measure the # of ldl paricles. Hdl-cholesterol, they measure the # of hdl paricles. For most people, eaing more cholesterol is not associated with higher blood levels. Not a main dietary target for reducing heart disease. Omega-3 fats (pufa) decrease vldl and increase hdl. Found in canola, lax, soy omega- 3 eggs. Recommends eaing at least 2 servings of ish per week.
