Muscle Mag Fitness spoke with health and nutrition expert Jeff Behar to get his advice about regarding heart disease and ways to lower cholesterol naturally. We sat down with Jeff at his facility in Los Angeles California. Muscle Mag Fitness: What is cholesterol exactly?Jeff Behar: Cholesterol is a type of fat (lipid) found in foods from animal sources. The body (the liver) also produces about 1,000 milligrams of cholesterol a day. Because cholesterol can't travel alone through the bloodstream, it has to combine with certain proteins so that they are able to be transported to different parts of the body. When this happens, the cholesterol and protein form what is called a lipoprotein. The two most important types of lipoproteins are high-density lipoproteins (or HDL) and low-density lipoproteins (or LDL). You've probably heard people call LDL cholesterol "bad cholesterol" and HDL cholesterol "good cholesterol" because of their very different effects on the body. Most cholesterol is LDL cholesterol, and this is the kind that's most likely to clog the blood vessels, keeping blood from flowing through the body the way it should. Only about one third to one fourth of the total amount of cholesterol is HDL cholesterol. HDL cholesterol carries cholesterol back to the liver, where it can be processed and sent out of the body; therefore HDL is often referred to as "good cholesterol". Muscle Mag Fitness: Why is it important to try to lower cholesterol if it is high and maintain healthy cholesterol levels?Jeff Behar: When you have too much cholesterol, it can be dangerous to your health. When LDL cholesterol levels are high, cholesterol is deposited on the walls of arteries and forms a hard substance called plaque. Over time, plaque causes the arteries to become narrower, decreasing blood flow and causing a condition called atherosclerosis or hardening of the arteries. When atherosclerosis affects the coronary arteries (the blood vessels that supply the muscles of the heart), the condition is called coronary artery disease, which puts a person at risk for having a heart attack. When atherosclerosis affects the blood vessels that supply the brain, the condition is called cerebral vascular disease, which puts a person at risk of having a stroke. Atherosclerosis may also block blood flow to other vital organs, including the kidneys and intestines. This is why it's so important to start paying attention to cholesterol levels as a teen - you can delay or prevent serious health problems in the future. Based on the biggest cholesterol study to date (Lancet 2007), if you lower cholesterol even by about 4 mg/dL at age 40-49, you reduce the risk of a fatal heart attack by half; at age 50-69, by a third; and at age 70-89, by a sixth. This applies to both men and women. This is quite significant considering that heart disease is one of the leading causes of death in the U.S and throughout the developed world. Although lowering cholesterol is important in reducing the risk to heart disease it is just one part of an important health management plan to reduce risks to heart disease. Eating a healthy diet, exercising daily, managing stress, maintaining your ideal weight, and restraining from smoking are also equally important when managing your risks for heart disease. All of these factors can have a huge positive impact on health. Muscle Mag Fitness: What Causes High LDL Cholesterol Levels?Jeff Behar: There are many things that can cause high LDL levels. The most common factors include:
Muscle Mag Fitness: Are there natural ways to lower cholesterol levels?Jeff Behar: You don't have to settle for prescription medications with life-long dependency and undesirable side effects to lower cholesterol levels. There are many preventative measures you can take and natural ways to lower cholesterol. Many ways are simple, yet still very effective. Some very simple yet effective approaches for lowering your cholesterol levels include:
Muscle Mag Fitness: What is HDL Cholesterol and Why are their Levels So Important?Jeff Behar: High-density lipoproteins (HDL), aka "good cholesterol", is one of the 5 major groups of lipoproteins (chylomicrons, VLDL, IDL, LDL, HDL) which enable lipids like cholesterol and triglycerides to move within the water based solution of the blood stream. Studies show that HDL cholesterol, aka "good cholesterol", appears to scour the walls of blood vessels, cleaning out excess cholesterol. HDL cholesterol then carries that excess cholesterol -- which otherwise might have been used to make the "plaques" that cause coronary artery disease -- back to the liver for processing. When a person's HDL cholesterol level is measured it is used to estimate how vigorously his or her blood vessels are being "scrubbed" free of cholesterol. In healthy individuals, about thirty percent of blood cholesterol is carried by HDL. Muscle Mag Fitness: What levels of HDL Cholesterol are considered good?Jeff Behar: HDL levels between 40 and 60 mg/dL are considered "normal." HDL levels greater than 60 mg/dL may actually protect people from heart disease. HDL levels below 40 mg/dL result in an increased risk of coronary artery disease, even in people whose total cholesterol and LDL cholesterol levels are normal. Bottom line, the medical community has known for years that when it comes to HDL levels, the higher the better.
*mg/dL = milligrams per deciliter
**mmol/L = millimoles per liter
Muscle Mag Fitness: Are there natural supplements one can take to help lower cholesterol?Jeff Behar: There are many natural supplements that have shown promise with lowering cholesterol levels. If most of your excess cholesterol is made by your body, B vitamins such as vitamin B3 (niacin) and pantethine have evidence to support their use. Niacin (AKA Nicotinic Acid, B3). Niacin is also another popular natural agent used to lower LDL cholesterol and increase HDL. Well-designed studies have found that niacin lowers LDL cholesterol by approximately 10%, lowers triglycerides by 25%, and raises "good" HDL cholesterol by 15% to 30%. Niacin also appears to significantly lower levels for another risk factor for atherosclerosis, lipoprotein Note, Niacin can increase the effect of high blood pressure medication or cause nausea, indigestion, gas, diarrhea, gout, and worsen peptic ulcers, or trigger gout, liver inflammation, and high blood sugar. It can also cause skin flushing or hot flashes, which is caused by widening of blood vessels. Although high doses of niacin showed promise in combination with drugs to lower cholesterol (called "satins"), there are concerns that combining them could result in a potentially fatal condition called rhabdomyolysis, therefore they shouldn't be combined unless under the close supervision of a physician. Pantethine. Pantethine is the biologically active form of pantothenic acid (Vitamin B-5) and the fundamental component of Coenzyme A. Pantethine participates in the metabolism of carbohydrates, amino acids, fatty acids and dozens of other important chemical reactions. Pantethine has been used for the past 30 years in Japan, where it is approved as a pharmaceutical agent for the purpose of increasing HDL-C. In the US, pantethine is sold as a supplement without a prescription in the United States. Pantethine works by slowing production of cholesterol in the liver and boosting the rate at which your metabolism uses fats. It significantly reduces levels of TC and LDL-C while raising HDL-C. It is the most effective natural product against serum TG levels. Pantethine is not known to cause significant side effects, has no known drug interactions, and may be the best choice for diabetics. It has not been known to cause birth defects. Jeff Behar: If you think most of your excess blood cholesterol is from the diet, there are additional natural alternatives that may also help lower your LDL and increase your HDL. Plant Sterols/Stanols. If you think most of your excess blood cholesterol is from the diet, plant sterols (such as beta-sitosterol and sitostanol) and/or stanols can help prevent the absorption of dietary cholesterol. These naturally-occurring substances found in certain plants. Stanols are also found as dietary supplements or are added to margarine, orange juice, and dressings have been given an FDA nod for their use in decreasing heart disease risk. Studies have found that stanols significantly reduced total cholesterol and LDL cholesterol, but had no significant effect on HDL cholesterol or triglycerides. Stanols and sterols appear to enhance the effects of other methods to lower cholesterol. In studies, people taking the statin drugs to lower cholesterol had an additional improvement in their cholesterol levels with stanols/sterols. Soluble Fiber. Soluble fiber also reduces LDL cholesterol by reducing cholesterol absorption in the intestines. Soluble fiber binds with cholesterol so that it is excreted. Five to 10 grams a day of soluble fiber has been found to decrease LDL cholesterol by approximately 5%. Soluble fiber can be found as a dietary supplement, such as psyllium powder, or in foods such as: oats, rye, barley, legumes (peas, beans), certain fruits (e.g., apples, prunes, and berries), certain vegetables (e.g., carrots, broccoli, yams, etc.) Jeff Behar: There are other supplements such as guggulipids, artichoke extract (Cynara scolymnus), policosanol, red yeast rice, Coq, and garlic - but the evidence is mixed. Guggulipids. Guggulipids is a natural ingredient derived from the mixture of plant chemicals (ketonic steroids) from the gum resin of commiphora mukul, called guggulipid, and is an approved treatment of hyperlipidemia (high cholesterol) in India. It has been a mainstay of traditional Indian herbal medicine (Ayurveda) approaches in preventing high cholesterol and atherosclerosis. It is believed that guggul helps reduce high cholesterol, because it lowers harmful LDL (low-density lipoproteins) while elevating the beneficial HDL (high-density lipoproteins). Studies have also shown that LDL oxidation, which is the main cause of plaque build in the arteries, can be prevented or at least decreased by the antioxidant activity of guggul. Guggul also has anti-inflammatory activity and reduces the levels of C-reactive protein. It helps prevent blood platelet aggregation and breaks up blood clots. Therefore there are practioners that believe that guggul can be used not only to lower bad cholesterol but can be used as a preventative against heart disease and stroke. Policosanol. Policosanol is a natural substance derived from sugar cane alcohols, primarily octacosanol. Millions of people needing to lower cholesterol in other countries have been using policosanol for years. It has just recently been introduced into U.S. markets. People are turning to this natural substance because of concerns over the safety statin drugs. There are limited studies indicating that those taking policosanol can expect up to a 25% reduction in LDL cholesterol. Artichoke leaf extract. Artichoke leaf extract may work by limiting the synthesis of cholesterol in the body. Artichokes also contain a compound called cynarin, believed to increase bile production in the liver and speed the flow of bile from the gallbladder, both of which may increase cholesterol excretion. A double-blind, placebo-controlled German study found that 1,800 mg of artichoke extract per day for six weeks significantly lowered total cholesterol by 18.5% compared to 8.6% in the placebo group and lowered LDL cholesterol by 22.9% compared with 6% in the placebo group. The ratio of LDL to HDL decreased by 20% in the artichoke group compared with 7% in the placebo group. There were no adverse effects associated with artichoke use. Larger clinical trials over longer periods are needed. Red Yeast Rice. Red yeast rice also has been used in China for over 1,000 years for medicinal purposes, most notably for improving blood circulation and for alleviating indigestion and diarrhea. Recently, red yeast rice has been developed by Chinese and American scientists as a product to lower blood lipids, including cholesterol and triglycerides. Although small scale studies using pharmaceutical-grade red rice yeast have demonstrated efficacy and safety, it is no longer legal to sell supplements containing red yeast rice in the United States. The main reasons the Food and Drug Administration (FDA) removed red yeast rice from the market in the United States were because there is concern that patients who take statin drugs when combined with red yeast rice products may increase their risk of muscle or kidney injury. The FDA also considers the products containing red yeast rice to be new, unapproved drugs for which marketing violates the Federal Food, Drug, and Cosmetic Act. Coenzyme Q10. Coenzyme Q10 is a fat-soluble nutrient also known as CoQ10, or ubiquinine primarily found in the mitochondria. The mitochondria are small bodies within cells that produce energy for the body. CoQ10 provides energy to the cells, stabilizes cell membranes and acts as an antioxidant (a substance that reduces damage that results from oxygen, such as is caused by free radicals). As for lowering cholesterol there are some reports that this supplement may have some benefit in ischemic heart disease, which occurs when there are already blockages in the coronary arteries. This claim is not yet proven. Co Q 10 has no effect on lowering cholesterol. Garlic. While some individual studies have shown that garlic can be effective in reducing "bad" cholesterol (LDLs), the overall body of evidence is inconclusive. A recent study conducted in 2007, appears to shed serious doubt on the reality behind garlic's reputation in this area. The researchers tested raw garlic and two different garlic supplements on nearly 200 adults with moderately high levels of LDL ("bad") cholesterol. After six months, the patients showed no improvements in their average cholesterol or other blood fats (lipids), no matter what kind of garlic they had consumed. SOURCES: Gardner, C.

Muscle Mag Fitness: What diet changes can one make to help support a lower cholesterol level?Jeff Behar: There are many changes that can be made to the diet that can help lower cholesterol. On a big-picture level, eat more natural, whole foods rather than processed foods; eat enough protein, lots of vegetables, complex carbohydrates and adequate amounts of healthy oils (which means no trans-fats, but more omega-3 fatty acids and monounsaturates like extra virgin olive oil). In terms of specifics, aim for at least 25 grams of fiber daily - through oatmeal, vegetables, whole grains and other fiber sources like psyllium husk. Try to have cold water fish like salmon (wild only) on a regular basis (studies say two servings a week) - if this is not possible, a reputable source of fish oil or omega-3 fatty acids is highly recommended. There are studies to support a Mediterranean diet which is generous with vegetables, fruits, beans, and whole grains, moderate amounts of fish and chicken, and low amounts of red meat, and olive oil as the main oil. Side note, extra virgin olive oil is high in polyphenols or plant pigments, which have been shown by themselves to improve cholesterol. And as always, don't overeat. If you're overweight, eat less and choose foods that have more nutrients per gram, such as vegetables, instead of empty calories from sugar, soda or white bread. It can take up to 6-12 months to see the effects of diet on cholesterol levels, so be patient, and be consistent. But you will feel better on so many levels, it's worth it. Muscle Mag Fitness: What are some lifestyle changes one can make to try to lower cholesterol naturally?Jeff Behar: These three simple lifestyle can make a huge impact if followed consistently:
Muscle Mag Fitness: Are there natural supplements available to increase HDL?Jeff Behar: Most evidence supports the use of niacin to increase HDL - up to 35%. The beneficial effect is dose dependent. Niacin can cause flushing which people don't like - in these cases, it makes sense to start at a low dose and slowly build up. If people end up taking large doses of niacin, it is important that they ask their doctor about checking for liver enzymes because liver injury is a potential side effect at high doses. There is evidence supporting the use of exercise, red wine, polyphenols in berries in increasing HDL too.
