Introduction Lipids are the building blocks of the fats and fatty substances found in animals and plants. They are microscopic layered spheres of oil, which, in animals, are composed mainly of cholesterol, triglycerides, proteins (called lipoproteins), and phospholipids (molecules made up of phosphoric acid, fatty acids, and nitrogen). Lipids do not dissolve in water and are stored in the body to serve as sources of energy. Cholesterol Cholesterol is present in all animal cells and in animal-based foods (not in plants). In spite of its bad press, cholesterol is an essential nutrient necessary for many functions, including: Repairing cell membranes Manufacturing vitamin D in the skin Producing hormones, such as estrogen and testosterone Possibly helping cell connections in the brain that are important for learning and memory Regardless of these benefits, when cholesterol levels rise in the blood, they can have dangerous consequences, depending on the type of cholesterol.

Chronic kidney disease in itself has been found to be an independent predictor for the development of heart disease and is associated with an overall poorer prognosis. This effect occurs throughout the entire spectrum of kidney failure ranging from those with mild kidney disease to even those who have had successful kidney transplants. In one study of a million people with kidney failure who were not yet on dialysis, the risk of developing atherosclerosis was almost 35 times more likely than the risk of needing some type of kidney replacement therapy. In fact, the American National Kidney Foundation, the American College of Cardiology, and the American Heart Association consider people with chronic kidney disease to be at equal risk of a future cardiovascular event when compared to those who have already had a heart attack . Many conditions that confer increased heart disease risk can also lead to chronic kidney damage. Some common examples are high blood pressur...
