Why is one form of cholesterol considered good and another bad? There are actually as many as 18 kinds of cholesterol, but to save confusion, doctors divide them into two categories: LDL (bad) and HDL (good). Your liver manufactures most of your cholesterol, and small amounts of it go toward a variety of healthy purposes, including creating hormones that help turn food and exercise into muscle. Serving as cholesterol chauffeurs are fat/protein bunches called lipoproteins, and that’s where the fun begins: Low-density lipoproteins tend to deposit cholesterol on artery walls, where it builds up and eventually interferes with blood flow. But the high-density variety seems to take cholesterol back to the liver, where it can be eliminated from the body.
Kimchi, a Korean fermented side dish commonly made from cabbage, radish or cucumber, is quickly gaining a following for its many health benefits. Kimchi is high in fiber and—because it's fermented—is loaded with good bacteria that help keep your gut healthy. Kimchi contains bioactive compounds that lower cholesterol by blocking cholesterol from being absorbed into the bloodstream. The good bacteria produced during fermentation also help lower cholesterol. Kimchi and sauerkraut are usually pretty high in sodium, so watch your portions if you're watching your salt intake.
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)
If you want to increase the benefits of the fats you eat, work out before you chow down. A study at the University of Missouri found that regular exercise prior to high-fat meals produces a large hike in HDL. I’m not suggesting that your excuse for indulging in high-fat meals ought to be a pre-meal workout, merely that exercise before a meal works to your heart’s advantage.
Plant stanols and sterols (such as beta-sitosterol and sitostanol) are naturally-occurring substances found in certain plants. Stanols are also found as dietary supplements or are added to margarine, orange juice, and dressings. Research suggests that plant stanols and sterols may help to lower cholesterol. They are similar in structure to cholesterol and may help block the absorption of cholesterol from the intestines.
While diet and exercise should be your two main options for fighting off LDL cholesterol, you can also look into the various dietary supplements that are on the market today. Consider omega-3 fish oils, artichoke extract, and green tea extract. Keep in mind that these natural products have not been fully proven to reduce your level of LDL cholesterol, but they may be able to help along the way.
Niacin (vitamin B3) is believed to block cholesterol production in the body. Although niacin in prescription supplement form appears to be most effective in increasing HDL, it may have side effects such as flushing, itching, and headache, so you may want to consider adding niacin-containing foods to your diet first. Niacin is found in high concentrations in crimini mushrooms, chicken breast, halibut, tomato, romaine lettuce, enriched bread, and cereals.
Other supplements that have been suggested for cholesterol have less evidence of being useful. In the case of red yeast rice, there is a potential danger because it contains a naturally-occurring form of lovastatin, a prescription drug. Garlic has now been shown to be ineffective for lowering cholesterol. Other supplements and food you may see touted include policosanol, coenzyme Q10, green tea, and soy.
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.

A meta-analysis looked at randomized controlled trials for artichoke extract for high cholesterol. They found three studies worth analyzing and two showed some effect in lowering total cholesterol. Adverse events were mild, transient, and infrequent. The study said that larger clinical trials over longer periods are needed. The conclusion was that the evidence was not convincing, and the Cochrane Review discontinued updating its analysis of this research as of 2016.
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.
So far, these studies have been disappointing, to say the least. The first major trial (concluded in 2006) with the first CETP inhibitor drug, torcetrapib (from Pfizer), not only failed to show a reduction in risk when HDL was increased but actually showed an increase in cardiovascular risk. Another study with another CETP inhibitor - dalcetrapib (from Roche) - was halted in May 2012 for lack of effectiveness. Both of these related drugs significantly increased HDL levels, but doing so did not result in any clinical benefit.
Stick to a Low-Carb Diet – Also known as a ketogenic diet, a low-carb diet can lead to several health benefits, including weight loss, reduced blood sugar levels, and, of course, an increase in your HDL cholesterol. This is great for those who suffer from diabetes, metabolic syndrome, or obesity, but in truth, anyone can benefit from this type of diet!
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.
