You've probably heard that fried foods of all kinds, hydrogenated oils, and full-fat dairy products are cholesterol bombs that are best avoided (and not just by those watching their cholesterol levels). The American Heart Association recommends that everyone restrict these foods, as they contain trans and saturated fats, the "bad" kind that raises LDL cholesterol and leads to plaque buildup in the arteries.
Part of the “French paradox”-lower heart-disease rates in butter-and-cream-feasting France-may stem from the HDL benefits of wine consumption. For some people, however, alcohol causes more troubles than it cures. “Men should limit themselves to one or two drinks a day,” Willett says. “After that, you start worrying about adverse consequences.” While any alcoholic beverage will do, the antioxidants in red wine or dark beer may give you an added benefit.
Of course, this was an N=1 experiment, meaning there’s only one subject in his experiment. It’s possible that Feldman is unusual. He thought the same thing, so he shared his data and sent an open invitation to people to try the protocol for themselves. As of now, more than 50 people have followed Feldman’s experiment. Virtually all of them reported the same results (it’s worth noting that they’ve all been on a high-fat, low-carb diet).
According to the Mayo Clinic, ideal HDL levels for both men and women are 60 milligrams of cholesterol per deciliter of blood. If a man’s HDL level is below 40 milligrams of cholesterol per deciliter of blood or a woman’s HDL level is below 50 milligrams of cholesterol per deciliter of blood, then disease risk, specifically heart disease, is considered to be heightened. Even if your HDL level is above the at-risk number (but below the desirable number), you still want to work on increasing your HDL level so you can decrease your heart disease risk. (9)
Altering your diet is the easiest way to lower your elevated LDL cholesterol, and should be your first course of action, as every cholesterol-lowering strategy starts with your dietary habits. A balanced diet consisting of fruits, vegetables, whole grains, fish, and various plants will significantly help you lower your LDL cholesterol level. It’s best to limit the amount of red meat, eggs, and dairy you consume. Plant-based diets not only help lower your LDL, but they can also help clear plaque buildup from your arteries.
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 to 30 minutes at a time) may be the most effective way to increase HDL levels. Recent evidence suggests that the duration of exercise, rather than the intensity, is the more important factor in raising HDL cholesterol. But any aerobic exercise helps.
If you’re one of the 73.5 million Americans who have unhealthy cholesterol levels, heart-healthy lifestyle changes are important ways to improve your cholesterol and prevent it from getting progressively worse. According to the Centers for Disease Control and Prevention (CDC), fewer than half of people with high LDL cholesterol (the type of cholesterol that puts you at risk for heart disease) are getting treated, and not even one in three have their high cholesterol under control.
Extra pounds increase your odds of having high LDL cholesterol levels and can lead to the development of heart disease, so you shouldn’t wait to lose weight. But you don’t need to lose a lot to improve your cholesterol levels. According to Healthline, any weight loss can increase your HDL cholesterol, while decreasing LDL levels. No matter how much you want to lose, start by making small changes. Reach out to a friend when you’re upset instead of reaching for Ben & Jerry’s. Munch on fresh fruit or vegetables instead of chips or cookies. And park at the farthest spot in the parking lot to sneak in a bit more activity. All of these little changes can add up to big results.
Saturated fats. Typical sources of saturated fat include animal products, such as red meat, whole-fat dairy products, and eggs, and also a few vegetable oils, such as palm oil, coconut oil, and cocoa butter. Saturated fat can increase your levels of "bad" LDL cholesterol. But it has some benefits, too — it lowers triglycerides and nudges up levels of "good" HDL cholesterol.
This healthy recipe pairs well with just about anything -- salmon, chicken, or game meat like bison and venison. It's also a superb go-to for quick-fix lunches or snacks. Ladle some into whole-wheat tortillas stuffed with crunchy veggies. Pour a cup or two into some chicken or vegetable stock for an easy soup. Or blend a big scoop of your beans and rice with a big bowl of lettuce greens and sliced tomatoes for a filling lunch salad.
However, although low levels of HDL predict increased cardiovascular risk, particularly in healthy individuals with no history of cardiovascular events, the relationship between HDL and CHD risk is complex, with HDL-C and cardiovascular disease having a nonlinear relationship. For example, research found that HDL levels above approximately 60 mg/dL showed no further improvement in prognosis, and the EPIC (European Prospective Investigation into Cancer and Nutrition)-Norfolk and IDEAL (Incremental Decrease in End Points through Aggressive Lipid Lowering) studies showed that very high levels of HDL may actually be associated with an increased risk of atherosclerotic disease.

Although your cholesterol levels are partially determined by your genetics, these tips above can help you increase your HDL levels naturally! Also, don’t forget to visit your doctor every few years to have your cholesterol checked and have a blood panel conducted. Your doctor can use this information to treat any early conditions you may have. After all, high cholesterol levels don’t show any symptoms!
HDL particles are heterogeneous. They can be classified as a larger, less dense HDL2 or a smaller, denser HDL3.  Normally, most of the plasma HDL is found in HDL3.  To add to the complexity of HDL classification, HDL is composed of 4 apolipoproteins per particle. HDL may be composed of apo A-I and apo A-II or of apo A-I alone. HDL2 is usually made up only of apo A-I, while HDL3 contains a combination of apo A-I and apo A-II. HDL particles that are less dense than HDL2 are rich in apo E.
As you already know, HDL is considered the good guy in the cholesterol game, and it can help your liver to get rid of the unhelpful cholesterol in your body. This is a very important task that HDL is able to accomplish since cholesterol can’t simply dissolve into the blood. The liver has the job of processing cholesterol among its other important jobs. HDL is the liver’s helper and a very good one at that. Having high levels of HDL reduces your risk for both heart disease and stroke, which is why you want to get your cholesterol under control. (10)
Fish can be fatty or lean, but it’s still low in saturated fat. Eat at least 8 ounces of non-fried fish each week, which may be divided over two 3.5- to 4-ounce servings. Choose oily fish such as salmon, trout and herring, which are high in omega-3 fatty acids. Prepare fish baked, broiled, grilled or boiled rather than breaded and fried, and without added salt, saturated fat or trans fat. Non-fried fish and shellfish, such as shrimp, crab and lobster, are low in saturated fat and are a healthy alternative to many cuts of meat and poultry.
It’s harder to increase HDL or "good" cholesterol than it is to lower LDL or total cholesterol. It’s estimated that up to 80 percent of the variation in HDL from person to person is due to genetic factors. But the following steps have been shown to boost HDL—and they are worth taking because they also lower total cholesterol and help protect the heart in many ways beyond their effect on HDL.
While cholesterol is normally kept in balance, an unhealthy diet high in hydrogenated fats and refined carbohydrates can disrupt this delicate balance, leading to increased cholesterol levels. This imbalance is manifested in elevated LDL (bad cholesterol) and low HDL (good cholesterol), which increases the risk of heart attack or stroke. Other causes can include physical inactivity, diabetes, stress and hypothyroidism.
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.
