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.
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.
If you’re getting worked up over high cholesterol, then start working out. Daily exercise can help raise your HDL cholesterol levels and reduce your LDL cholesterol, while protecting you from many health conditions. Begin by choosing an activity that sounds like fun to avoid “workout burn-out.” Consider jogging, brisk walking, cycling, tennis, swimming or hitting the gym. Find an exercise partner to make the activity more enjoyable and help you stay on track. And while exercise can lower your cholesterol, it can also reduce your stress and anxiety. So working up a sweat can also save you from sweating the small stuff.
Olive oil is a plant-based fat, so it's a better choice when you're trying to lower your "bad" cholesterol than fats that come from animals. It’s great mixed with red wine vinegar, a minced garlic clove, and a little ground pepper for a salad dressing. For something different, try braising vegetables like carrots or leeks. Just drizzle 3 tablespoons of oil over vegetables in a snug baking dish, scatter some herbs, cover with foil, and put in a 375-degree oven for about 45 minutes.
I very simply lowered my cholesterol 57 points in 6 month (257 to 200) and my ldl from 158 to 132 by not eating meat. It has now been a year since I stopped eating meat, I cannot exercise due to major surgery but lost 50lbs and will have my cholesterol retested in September for my annual checkup. I’m also planning on going back to the gym soon. High cholesterol runs in my family and I was determined not to go on medication like my mom. I gained 30lbs when I was injured, I did not intend to go back to my weight as a teenager when I stopped eating meat, just lower my cholesterol, that was just a perk. I never deprive myself of food, I eat fish and I don’t miss meat from my diet at all. It was a conscience choice I made to try and lower my cholesterol, no one told me to or advised me but it worked and I’m happy I took the path. Good luck to all and stay healthy!
As if we needed another excuse to grab a second scoop of guac at the tailgate? Avocados are the poster child for the heart-healthy diet due to their rich abundance of monounsaturated fat, high fiber, and potassium. Monounsaturated fats from avocados, in particular, have been connected to an increase of HDL cholesterol and decreases of total cholesterol, LDL particles, and triglycerides, as shown in an Archives of Medical Research study. These can even be substituted for heart-harmful hydrogenated oils in baked goods as the fruit yields the same creamy texture and mouthfeel. Avocado brownies anyone?!
High levels of HDL cholesterol, often called "good" cholesterol, are associated with a reduced risk of coronary artery disease (CAD). It appears that HDL particles "scour" the walls of blood vessels, cleaning out excess cholesterol that otherwise might have been used to make the plaques that cause CAD. The HDL cholesterol is then carried to the liver, where it is processed into bile, and secreted into the intestines and out of the body.
As defined by the US National Cholesterol Education Program Adult Treatment Panel III guidelines, an HDL cholesterol (HDL-C) level of 60 mg/dL or greater is a negative (protective) risk factor.  On the other hand, a high-risk HDL-C level is described as being below 40 mg/dL. Randomized, controlled clinical trials have demonstrated that interventions to raise HDL-C levels are associated with reduced CHD events. A prospective analysis by Mora et al investigated the link between cholesterol and cardiovascular events in women and found that the baseline HDL-C level was consistently and inversely associated with incident coronary and coronary vascular disease events across a range of LDL-C values. 
A desirable level of LDL (“bad”) cholesterol is less than 100 mg/dL – the lower your LDL, the better in terms of heart disease risk. Levels between 139 and 150 mg/dL are borderline high and those between 160 to 189 mg/dL are considered high, while LDL levels above 190 mg/dL are classed as very high. According to the American Heart Association, the mean level of LDL cholesterol for American adults age 20 and older is 115.0 mg/dL.
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.
While the world of wellness endlessly touts of benefits of anti-inflammatory foods, who knew eating these could kill two birds with one stone by also improving your cholesterol? Blueberries are rich in anthocyanins, the phytochemical that gives this berry its dark blue pigment and are essential to overall heart health through enhancing anti-inflammatory pathways as well as increasing HDL cholesterol levels, according to a study in The American Journal of Clinical Nutrition. One 2013 study found that consuming blueberries in tandem with exercise can increase HDL levels even more than exercise alone.
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.
A cup of tea does more than soothe on a stressful day. Both green and black tea can help lower cholesterol levels. Green tea is prepared from unfermented leaves and black tea from fully fermented leaves of the same plant. Researchers believe that catechins, a type of antioxidant found in tea, are responsible for its cholesterol-lowering effect. The more fermented the tea leaves, the lower the catechin content and the higher the caffeine content.
Many fruits contain soluble fiber, which is important for lowering cholesterol, but apples have a leg up on other fruits. Apples (especially the skins) contain pectin, a type of soluble fiber that latches onto the "bad" cholesterol and guides it through your digestive system and out of your body, effectively lowering your LDL-cholesterol levels. Citrus fruits are also high in pectin, but since it's mostly in the pulp, you'll have to eat your fruits to get the benefits, rather than juice them. Luckily, apples are a little easier to pucker up to than lemons. Apples are also high in polyphenols, powerful antioxidants that help reduce inflammation.
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.
Pick Purple Produce – Did you know that eating purple-colored vegetables and fruits can potentially increase your HDL cholesterol? That’s because these specific foods contain antioxidants called anthocyanins, which have been shown to help fight inflammation and protect your cells from free radicals. When you can, fill up your plate with purple produce like eggplant, purple corn, red cabbage, blueberries, blackberries, and black raspberries.
Along with exercising, eating a healthy diet is one of the most important things you can do to reach and maintain healthy cholesterol levels. Learn how to read nutrition labels and know the difference between healthy and unhealthy fats. Calories, calories from fat, total fat, saturated fat, and trans fat numbers are all right there on the nutrition facts label to help you make heart-healthy choices.
A study of over 1 million US veterans showed a U-shaped relationship between HDL and total mortality, with 50mg/dL as the level associated with the lowest mortality. [7, 2] In addition, an analysis of the Framingham study demonstrated that LDL and triglyceride levels modify HDL’s predictive value; CHD risk was found to be higher when low HDL was combined with high LDL and/or triglycerides as compared with the presence of low HDL levels alone. [8, 2] The relationship between HDL and CHD risk is also confounded by the presence of pro-atherogenic and inflammatory markers. 
Too much cholesterol in the blood builds up on artery walls causing hardening of the arteries (atherosclerosis). The buildup of cholesterol narrows arteries, slowing or blocking the flow of oxygen-carrying blood to the heart, which can manifest as chest pain. If blood flow to the heart is cut off because of clogged arteries, the result is damage to the heart muscle – a heart attack.
Where HDL is concerned, “you can’t be too thin,” Castelli says. One report found about a 1 percent rise in HDL for every pound of fat lost. This doesn’t mean you have to turn yourself into a toothpick, but that you should work on getting rid of excess flab as you add muscle. (Use a body-fat monitor rather than a scale to chart your progress.) Fortunately, fat loss is likely to go hand in hand with the exercise and dietary modifications that also raise HDL levels.
A: Before I answer that question, why bother to increase HDL cholesterol at all? Many studies have found that people with low levels of HDL are at increased risk for heart attacks, strokes, and other complications of arteries diseased by atherosclerosis: that's why we call HDL the "good" cholesterol. Given that, you'd think that raising HDL levels would reduce a person's risk for atherosclerosis. Unfortunately, despite a lot of research, we don't yet know if that's true, nor how best to raise HDL levels.

A study published in January 2016 in the journal Nutrients found that an antioxidant-rich diet raises HDL cholesterol levels in relation to triglycerides, and might be associated with a reduced risk of stroke, heart failure, and inflammatory biomarkers. Antioxidant-rich foods include dark chocolate, berries, avocado, nuts, kale, beets, and spinach.
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!
Take fish oil. Fish oil contains an abundance of essential omega-3 fatty acids (omega-3s) that have been shown to lower triglyceride (blood fat) levels, minimize inflammation and clotting, and increase HDL (“good”) cholesterol. Research indicates that omega-3s may help reduce the risk and symptoms of a variety of disorders influenced by inflammation, including heart attack and stroke. You can add omega-3s to your diet by eating more cold water fish such as wild Alaskan salmon, sardines, herring, mackerel and black cod. If that’s not possible, Dr. Weil recommends taking two grams daily of a fish oil supplement that contains both essential omega-3 fatty acids, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). When choosing a supplement, look for one derived from molecularly distilled fish oils – these are naturally high in both EPA and DHA and low in contaminants. Also choose a supplement brand that has been independently tested and guaranteed to be free of heavy metals such as mercury and lead, and other environmental toxins including polychlorinated biphenyls, also known as PCBs.
Besides putting your heart health at risk, sugar is also known to be one of the most significant contributors to metabolic syndrome. In fact, the recent 2015 Dietary Guidelines labeled sugar as a “nutrient of concern” and voiced recommendations for added sugars to not exceed greater than 10% of total daily calories. So, if your goal is to nip sugar in the bud and increase your HDL cholesterol levels, start by evaluating your libations.
