Thanks to everyone who wrote in about this. Here's a little more information. You're right in that HDL levels should always be high as a component of total cholesterol. Generally speaking, higher HDL levels are healthier. And if your HDL is in the "high" range, that doesn't mean the same as the "at risk" range when HDL is too low. High HDL is okay, even good, as long as total cholesterol is low. But as with any, reading, there is an optimal range. Think of it this way: What would happen it your HDL levels were extremely elevated--much higher than 60? Naturally, it would raise your total cholesterol level, and high total cholesterol is a key risk factor for heart disease. The lower one's total cholesterol, the better.

As we mentioned in the article, however, heart-disease risk is about more than just numbers. Other factors including fasting insulin, microinfection, inflammation ...
