How much do you know about your cholesterol? You probably know that there are two different kinds – high-density lipoprotein (HDL), which is the “good” cholesterol, and low-density lipoprotein (LDL), also known as the “bad” cholesterol. High HDL levels help carry cholesterol from your arteries to your liver and also possess antioxidants and anti-inflammatory properties, which are linked to a reduced risk of heart disease.
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.
Lentils are pulses, a.k.a. the dry edible seeds of certain crops (like beans, chickpeas, and peas). Pulses are just everywhere these days because they’re packed with plant-based protein and fiber, not to mention antioxidants, minerals, and B vitamins. All of those compounds help protect you from plaque buildup while optimizing blood flow and assisting your body in efficiently using the nutrients you consume.
Aside from the inconvenience of taking niacin, two recent, highly-anticipated clinical trials have suggested that raising HDL levels with niacin failed to demonstrate any improvement in cardiovascular outcomes. Furthermore, treatment with niacin was associated with an increased risk of stroke and increased diabetic complications. At this point, most doctors are very reluctant to prescribe niacin therapy for the purpose of raising HDL levels.
Research shows that there isn't really a link between how much fat you eat and your risk of disease. The biggest influence on your risk is the type of fat you eat. Two unhealthy fats, including saturated and trans fats, increase the amount of cholesterol in your blood cholesterol and increase your risk of developing heart disease. However, two very different types of fat — monounsaturated and polyunsaturated fats — do just the opposite. In fact, research shows that cutting back on saturated fat and replacing it with mono and polyunsaturated fats can help lower the level of LDL cholesterol in your blood.
Do you dread opening up the white envelope of lab results after your annual physical only to discover a jumble of numbers, red ink, and arrows pointing every possible direction? Lipid or cholesterol panel results can be confusing to comprehend, and when numbers come back “out of range” it can only further fuel feelings of discouragement and helplessness.

Starting a simple exercise routine is another way to help lower your elevated LDL cholesterol level. And if you compound working out with the dietary tips listed above, you could potentially lower your LDL level by over 37 percent and increase your HDL cholesterol by over 5 percent in just two months. Not to mention the added benefits of losing weight, decreased stress, and higher energy, exercising is an all-around great activity to incorporate into your life. Aim for 30 minutes of physical activity, four to five times each week, and you’ll be well on your way.
Including fish in your diet can increase HDL cholesterol in a short period of time. In a study published in February 2014 in the journal PLoS One, researchers concluded that a diet rich in foods including fish showed an increase in the size of HDL particles in the body, which could help improve cholesterol transport through the body. The researchers saw the positive effects of a diet that included fish in as little as 12 weeks.
Once you control your protein and starch portions, you can fill the rest of your plate with heart-healthy fruits and vegetables. Aim for four to five servings of vegetables and four to five servings of fruits every day. Fruits and vegetables are rich in vitamins and minerals and are great sources of fiber, which helps fill you up, control your weight, and improve cholesterol levels.
You don’t have to lose a lot of weight to lower your cholesterol. If you’re overweight, drop just 10 pounds and you’ll cut your LDL by up to 8%. But to really keep off the pounds, you’ll have to do it over time. A reasonable and safe goal is 1 to 2 pounds a week. The National Heart, Lung and Blood Institute notes that while inactive, overweight women usually need 1,000 to 1,200 calories daily for weight loss, active, overweight women and women weighing more than 164 pounds usually require 1,200 to 1,600 calories each day. If you’re extremely active during your weight-loss program, you may require additional calories to avoid hunger.
Salmon is rich in omega-3 fatty acids, which are healthy fats that can help reduce blood pressure. Eating salmon can improve your "good" HDL cholesterol, but it won't lower your "bad" LDL cholesterol. HDL cholesterol helps sweep cholesterol off your artery walls, preventing dangerous plaque from forming. The American Heart Association recommends eating fatty fish like salmon at least twice per week for heart-healthy benefits. Other fish that contain omega-3s, such as mackerel, tuna and sardines, can also help.
HDL plays an important role in transporting cholesterol from the peripheral tissues to the liver, where it can be excreted; this process is known as reverse cholesterol transport (RCT). (The liver is the main organ for excretion of cholesterol, doing so either directly or by converting cholesterol into bile acids.) It is important to remember that most HDL measured in the blood is derived from the liver and intestine. Therefore, the concentration of HDL in plasma does not reflect cholesterol efflux from blood vessels or the efficiency of RCT. Moreover, HDL function in RCT is not mirrored by HDL measurements.
