Ways to boost up HDL

Good Cholesterol is one of the many types of cholesterols we have circulating in our blood. It is known as high density lipoprotein cholesterol. It’s one of the blood fats measured in the lipid panel blood test doctors perform. And it’s the component that we want more of, because increasing HDL helps lower your risk of heart disease.

  • HDL cholesterol normally makes up 20%-30% of total blood cholesterol.
  • There’s some evidence that HDL helps protect against the accumulation of plaques (fatty deposits) in the arteries.
  • Research has given some indication that a 1% decrease in HDL cholesterol is linked to a 2%-3% increase in heart disease risk.
  • HDL cholesterol levels are thought to have a genetic factor in some people.
  • Women typically have higher HDL cholesterol levels than men. It is considered that levels of less than 40 mg/dL is low.

Some diet and lifestyle changes may help to increase “good” cholesterol levels.

Orange Juice. Drinking three cups of orange juice a day increases HDL levels by 21% over three weeks

Niacin. There is some evidence niacin (vitamin B3) helps increase HDL.

Blood Sugar. Food that increases your blood sugar tend to lower the HDL level.

Type of Fat in Diet. Replacing saturated fats with monounsaturated fats can not only help reduce levels of “bad” cholesterol, it may also increase levels of “good” cholesterol.

Soy. Soy protein, plus the isoflavones found in soy raised HDL levels, which could reduce coronary heart disease risk.

Alcohol in Moderation. Drinking moderate amounts of alcohol, especially with meals, appears to do two things to help reduce heart disease risk. it is said to increase HDL cholesterol levels, and enhances the movement of cholesterol deposits out of cells in the artery walls.

Aerobic exercise. At least 30 minutes on most days of the week is the exercise prescription that can help raise your HDL.

Losing weight. Being overweight or obese contributes to low HDL cholesterol levels. Thus loosing weight would help in increasing HDL.

The ancient herb red clover (Trifolium pratense), long used to ease estrogen-related menopausal symptoms, has now been found to significantly increase HDL (good) cholesterol levels in postmenopausal women.

Lipid Metabolism

Lipid Metabolism

Most of the dietary fat is absorbed into the blood in chylomicrons. Triglyceride is removed from the chylomicrons by lipoprotein lipase in the blood, fatty acids released are taken up by the adipose tissue (Fat storage tissue) and the chylomicron ramnants are removed by the liver.Triglyceride taken up by the liver is broken down to 2-carbon fragments which are used in many metabolic processes. Free fatty acids liberated by the adipose tissue is also taken up by the liver and used in simillar way.
In these processes lipid aggregates are formed containing triglycerides, phospholipids and cholesterol. These are combined with apoproteins to form Lipoproteins which are released into the blood.
These Lipoproteins are:
1. VLDL – Very Low Density Lipoproteins
2. IDL – Intermediate density Lipoproteins
3. LDL – Low Density Lipoproteins
4. HDL – High Density Lipoproteins

The density of the lipoproteins is determined by the relative protein and lipid content with high density lipoproteins containing high protein and less lipids.

The liver synthesises more cholesterol than any other organ. The cholesterol is incorporated into lipoproteins or converted to bile acids or excreted into bile. In biliary obstruction of any kind serum lipid concentration increases mainly due to formation of abnormal lipoprotein known as Lipoprotein X.
