Many people don't like to hear it, but regular aerobic exercise (any exercise, such as walking, jogging or bike riding, that raises your heart rate for 20 to 30 minutes at a time) may be the most effective way to increase HDL levels. Recent evidence suggests that the duration of exercise, rather than the intensity, is the more important factor in raising HDL cholesterol. But any aerobic exercise helps.
Foods naturally rich in soluble fiber have proven particularly good at lowering cholesterol. Excellent sources include oats, oat bran, barley, peas, yams, sweet potatoes and other potatoes, as well as legumes or beans, such as pinto beans, black beans, garbanzo beans, and peas. Vegetables rich in soluble fiber include carrots, Brussels sprouts, beets, okra, and eggplant. Good fruit sources are berries, passion fruit, oranges, pears, apricots, nectarines, and apples.
Too much cholesterol in the blood builds up on artery walls causing hardening of the arteries (atherosclerosis). The buildup of cholesterol narrows arteries, slowing or blocking the flow of oxygen-carrying blood to the heart, which can manifest as chest pain. If blood flow to the heart is cut off because of clogged arteries, the result is damage to the heart muscle – a heart attack.
First, a quick explainer: Cholesterol is a waxy substance that travels through your bloodstream, but not all of it is bad. HDL cholesterol (a.k.a. "good" cholesterol) actually sweeps away LDL cholesterol, or the "bad" kind. A high LDL level puts you at risk for heart attacks and strokes because it can clog arteries with plaque, a condition called atherosclerosis. A blood test can determine whether you have high cholesterol, and your doctor may recommend exercise or medication in addition to a healthier diet.
1. Oats. An easy first step to improving your cholesterol is having a bowl of oatmeal or cold oat-based cereal like Cheerios for breakfast. It gives you 1 to 2 grams of soluble fiber. Add a banana or some strawberries for another half-gram. Current nutrition guidelines recommend getting 20 to 35 grams of fiber a day, with at least 5 to 10 grams coming from soluble fiber. (The average American gets about half that amount.)
There is some research suggesting that artichoke leaf extract (Cynara scolymnus) may help to lower cholesterol. Artichoke leaf extract may work by limiting the synthesis of cholesterol in the body. Artichokes also contain a compound called cynarine, believed to increase bile production in the liver and speed the flow of bile from the gallbladder, both of which may increase cholesterol excretion.
You've probably heard that fried foods of all kinds, hydrogenated oils, and full-fat dairy products are cholesterol bombs that are best avoided (and not just by those watching their cholesterol levels). The American Heart Association recommends that everyone restrict these foods, as they contain trans and saturated fats, the "bad" kind that raises LDL cholesterol and leads to plaque buildup in the arteries.
