Avoid trans-fatty acids. These heart-damaging fats can reduce HDL (“good”) cholesterol levels and raise levels of LDL (“bad”) cholesterol. The tip-off that trans-fatty acids are present in foods is the listing of “partially hydrogenated oil” on a food’s ingredient list. Trans-fats are found in many brands of margarine and in most heavily processed foods, as well as in snack foods such as chips, crackers and cookies, and in the oils used to cook fast-food French fries, doughnuts and movie popcorn.

Not all oils are created equal when it comes to your heart health. Olive oil and soybean oil are mainly unsaturated fat, which can lower LDL cholesterol and at the same time increase HDL cholesterol. In a study published in July 2015 in The Journal of Nutrition, researchers found that including olive oil in the diet decreased LDL concentrations in healthy young men.
It’s a very common misconception that cholesterol is generally bad and high levels are always cause for serious concern. But what if I told you that there is a type of cholesterol that’s not only good at higher levels, but also decreases your risk of major health issues like heart disease? I have great news: This type of cholesterol really does exist. It’s called HDL cholesterol, and it’s our “good” cholesterol.
The most important mechanism by which HDL exerts its antiatherogenic role is the removal of excess cholesterol from peripheral cells and its transport to the liver, a process commonly termed the reverse cholesterol transport system (RCT). Several proteins are involved in this process, including ATP-binding cassette transporter 1, LCAT, CETP, and hepatic triglyceride lipase (see Pathophysiology). [25]
Sugar and spice and everything nice… except for the fact that recent data has shown that added sugar is not so nice for our cardiovascular health or waistlines. In fact, a study published in Circulation found that people with the highest consumption of added sugars show significantly lower HDL levels. To cut back on your added sugar intake and increase HDL levels, consider replacing sugar with dates when you’re making baked goods like homemade granola bars, cookies, and cakes. It’s one way to slice total added sugars in half and will also give your sweet treat extra fiber, vitamins, and minerals.

In a Canadian study, drinking a few glasses of orange juice every day for four weeks increased participants’ HDL by 21 percent, possibly due to a flavonoid called hesperidin that appears extremely HDL-friendly. Subsequent research found that tangerine juice may be even more effective. Unfortunately, that much juice will add hundreds of excess sugar calories to your diet. So stick to a glass a day and be satisfied with lesser results. Or you can buy hesperidin as a supplement, though it won’t replace the many beneficial nutrients of orange juice (and certainly won’t taste as good).

Coronary heart disease: What you need to know The coronary arteries supply oxygen and blood to the heart. They can narrow, often because cholesterol accumulates on the arteries’ walls. This results in coronary heart disease, the most common type of heart disease in the U.S. Here, learn about risk factors, early warning signs, means of prevention, and treatments. Read now


In randomly screened children aged 6-19 years who had age-, race-, and sex-specific total plasma cholesterol levels greater than or equal to 95th percentile levels, 7.8% of white males, 12.8% of white females, 25% of black males, and 17.2% of black females had hypercholesterolemia due to elevated high-density lipoprotein [HDL] cholesterol levels (but not due to elevated low-density lipoprotein [LDL] cholesterol levels) greater than age-, sex-, and race-specific 95th percentile levels. That is, they had HALP.
Barley contains a powerful type of soluble fiber that helps keep cholesterol levels in check by effectively lowering total and LDL cholesterol without affecting HDL. This beta-glucan fiber works by preventing the body's absorption of cholesterol from food. Look for minimally processed pearled barley, the variety most commonly found in supermarkets.

However, environmental factors also have a significant impact on HDL levels. Factors that elevate HDL concentrations include chronic alcoholism, treatment with oral estrogen replacement therapy, extensive aerobic exercise, and treatment with niacin, statins, or fibrates. [11, 12, 13] On the other hand, smoking reduces levels of HDL-C, while quitting smoking leads to a rise in the plasma HDL level.
Controlling your weight is an important part of getting to healthy cholesterol levels, so it’s crucial to know your portion sizes if you're trying to lower cholesterol. A portion of starchy carbohydrate, like potato or pasta, should be only about half the size of a baseball. A heart-healthy portion of meat should be about the size of a deck of playing cards, or about three ounces.
A study published in February 2016 in the journal PLoS One concluded as much. For nearly 11,000 adults, researchers found that low to moderate alcohol consumption (20 or fewer drinks a week for a man, 10 or fewer for a woman) led to higher levels of HDL cholesterol. It also helped get them to healthier overall cholesterol levels, decreasing triglycerides (blood fats in blood) and lowering LDL cholesterol.

The lipid profile blood test reports the levels of cholesterol and triglycerides in the bloodstream. Healthcare organizations have established a set range for total, bad LDL and good HDL cholesterol as well as triglycerides, but the most important thing to consider when looking for how to lower cholesterol naturally is the ratio of LDL to HDL cholesterol, which should be around 2:1.

An interaction between the human cholesteryl ester transfer protein (CETP) and apolipoprotein A-I genes in transgenic mice results in a profound CETP-mediated depression of high density lipoprotein cholesterol levels.

And according to some powerful experiments by software engineer-turned-biohacker Dave Feldman, you can actually increase and decrease your cholesterol at will. It all depends on how much fat you eat — and, directly against mainstream dietary knowledge, the correlation is inverted. In other words, eating more fat will actually lower your cholesterol.
