How does that song go? "Beans, beans, they're good for your heart"? Well...those lyrics get it right! Beans are packed with cholesterol-busting soluble fiber, but that's not their only benefit. Beans are high in protein, which makes them a heart-healthy replacement for some animal protein sources, such as meat. For the biggest cholesterol-lowering benefits, add beans to chili, tacos and burritos (either in place of or in addition to meat). They're also great in soups and salads.
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.
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.

An interaction between the human cholesteryl ester transfer protein (CETP) and apolipoprotein A-I genes in transgenic mice results in a profound CETP-mediated depression of high density lipoprotein cholesterol levels.

HDL is actually more complex than we once thought. Rather than being a single kind of particle, HDL is is now considered a family of different particles. All HDL contains lipids (fats), cholesterol and proteins (called apolipoproteins), but some types of HDL are spherical while others are shaped like a doughnut. Some HDL types remove bad cholesterol from the blood while other types are indifferent to cholesterol. Or even worse, some HDL transfers cholesterol the wrong way (into LDL and cells) or protects LDL in a way that makes it more harmful to the arteries.
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.
