Over-consumption of carbohydrates is associated with low levels of HDL, or "good", cholesterol. Researchers recently evaluated 619 individuals for carbohydrate consumption, HDL levels, and triglyceride levels. Those with the highest level of carbohydrate intake had the highest levels of triglycerides, and the lowest levels of HDL's. They noted in particular that sugar-containing soft drinks, juices, and snacks were associated with low HDL's.
In my cholesterol article I review research indicating that high triglycerides and low HDL cholesterol is the worst combination to have. LDL cholesterol, often referred to as "bad" cholesterol, exists in different sizes. Larger LDL particles are not a problem, whereas small LDL particles are a problem. If you have low HDL levels and high triglyceride levels, you probably have the "bad" LDL cholesterol. If you have high HDL's and low triglycerides, you probably have the harmless form of LDL's--regardless of the amount!
How do you raise HDL's and lower triglycerides? My Cholesterol Article explains it all!
