“The proposed change reflects a major shift in the scientific view of cholesterol that has taken place in recent years.

Although serum cholesterol is still considered an important risk factor, cholesterol consumed in food is now thought to play a relatively insignificant role in determining blood levels of cholesterol.”

However, if you process saturated fat or cholesterol and heat it by frying, then you create very dangerous products that will clearly increase your risk of cardiovascular disease. So this new information does not give you free license to eat any type of cholesterol. Remember, trans fats are worse than sugar for your health.

“[I]n the latest review of studies that investigated the link between dietary fat and causes of death, researchers say the guidelines got it all wrong. In fact, recommendations to reduce the amount of fat we eat every day should never have been made.”

Depending on the size of the particles, LDL may be either harmful or harmless, so LDL is not necessarily “bad” across the board. The issue of particle sizes is discussed in greater detail in my 2013 interview with Chris Kresser, L.Ac. If you’ve had your cholesterol levels checked, your doctor most likely tested your total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. But we now know those are not accurate predictors for cardiovascular disease risk.

A far more accurate predictor is your LDL particle number, the test for which is called an NMR Lipoprofile. It’s easy to get and all major labs offer it, including LabCorp and Quest. Most insurance policies cover the test as well. Best of all, even if your doctor were to refuse to order it, you can order it yourself via third-party intermediaries like Direct Labs, or you can order the test online, and get blood drawn locally. Also:

Check your HDL to total cholesterol ratio. HDL percentage is a potent heart disease risk factor. Just divide your HDL level by your cholesterol. This ratio should ideally be above 24 percent.

Boost your HDL cholesterol and lower your triglyceride levels. High triglycerides are a very potent risk factor for heart disease. In combination, high triglycerides and low HDL levels are an even bigger risk; this ratio is far more important to your heart health than the standard good vs. bad cholesterol ratio. In fact, one study found that people with the highest ratio of triglycerides to HDL had 16 times the risk of heart attack as those with the lowest ratio of triglycerides to HDL.

You calculate your triglyceride/HDL cholesterol ratio by dividing your triglyceride level by your HDL level. This ratio should ideally be below 2. So while you strive to keep your HDL cholesterol levels up, you'll want to decrease your triglycerides. You’ll find strategies for increasing your HDL level below. Triglycerides are easily decreased by exercising and avoiding grains and sugars in your diet.
