Increasing the GOOD cholesterolWhile it has been known for a number of years that high HDL cholesterol levels (the "good" cholesterol) seem to confer some degree of protection from heart disease, until relatively recently almost all the attention in the "cholesterol wars" has been focused on lowering total cholesterol and LDL cholesterol levels (the "bad" cholesterol.) Click here for a quick review of cholesterol and triglycerides.It was not until the last few years that low HDL cholesterol levels have been recognized as an independent risk factor for heart disease. That is, even if their total cholesterol and LDL cholesterol levels are normal, people with reduced levels of HDL have an increased risk of early coronary artery disease. (HDL levels, to be considered "normal," should be at least 35 - 40 mg/DL.) Why is HDL cholesterol protective? It appears that it’s not the cholesterol itself that is good, it’s the "vehicle." The HDL molecule is a complex molecule consisting of protein, lipids, and cholesterol. The HDL molecule, it appears, “scours” the walls of blood vessels, and cleans out excess cholesterol. If this is the case, the cholesterol being carried by HDL (that is, the “good” HDL cholesterol) is actually “bad” cholesterol that has just been removed from blood vessels, and is being transported back to the liver for further processing. Even recognizing the fact that low HDL cholesterol levels are bad, doctors still tend to emphasize that their patients must reduce the bad cholesterol, and tend to neglect helping them raise the good cholesterol. This is a shame, since many people with normal or near normal total cholesterol levels have reduced HDL levels - and are therefore still at increased risk for heart disease.
Who needs to increase their HDL levels?Anyone whose HDL level is below 40 mg/DL should consider taking steps to increase their HDL. This is the case even if total cholesterol and LDL cholesterol levels are within the normal range.
What measures can be used to increase HDL levels?Aerobic exercise. 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 - 30 minutes at a time) increases the HDL levels.Lose weight. Obesity results not only in increased LDL cholesterol, but also in reduced HDL cholesterol. If you are overweight, reducing your weight should increase your HDL levels. Stop smoking. If you smoke, giving up tobacco will result in an increase in HDL levels. (This is the only advantage I can think of that smokers have over non-smokers - it gives them something else to do that will raise their HDL.) Cut out the trans fatty acids. Trans fatty acids are currently present in many of your favorite prepared foods - anything in which the nutrition label reads "partially hydrogenated vegetable oils" - so eliminating them from the diet is not a trivial task. But trans fatty acids not only increase LDL cholesterol levels, they also reduce HDL cholesterol levels. Removing them from your diet will almost certainly result in a measurable increase in HDL levels. Click here for a quick and easy review of trans fatty acids and the heart. Alcohol. With apologies to the American Heart Association, which discourages doctors from telling their patients about the advantages of alcohol: one or two drinks per day can significantly increase HDL levels. More than one or two drinks per day, one hastens to add, can lead to substantial health problems including heart failure - and there are individuals who will develop such problems even when limiting their alcohol intake to one or two drinks per day.

Monounsaturated fats such as canola oil, avocado oil, or olive oil and in the fats found in peanut butter can increase HDL cholesterol levels without increasing the total cholesterol. Add soluble fiber to your diet. Soluble fibers are found in oats, fruits, vegetables, and legumes, and result in both a reduction in LDL cholesterol and an increase HDL cholesterol. For best results, at least two servings a day should be used. Page 2 - Diet and Drugs to Raise HDL |
