part of cell membranes. Also all male and female hormones are chemically made from cholesterol.
Lipoproteins are large molecules that transport lipids (cholesterol and triglyceride) and fat-soluble vitamins from the liver and intestine to the tissues and vice versa. The lipoproteins in the blood are classified into five major classes based on their relative densities. They are chylomicron, very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL).
Most triglyceride is carried in chylomicron and VLDL, and most cholesterol is transported in LDL and HDL. Cholesterol is transported by LDL from the liver to the tissues, and it is carried back to the liver and intestine by HDL. This is why LDL and HDL are often called as bad cholesterol and good cholesterol, respectively.
An increase in the blood levels of LDL and TG and a decrease in the blood level HDL would increase the risks of cardiovascular diseases. Normal levels of fats in the blood are as follows:
Fats | Normal Levels in the Blood |
Total cholesterol | Below 200 mg/dl |
LDL cholesterol | Below 100 mg/dl |
HDL cholesterol | 35 – 60 mg/dl |
Triglyceride (TG) | Below 150 mg/dl |
Potential causes of high levels of LDL and TG:
- Genetics and familial.
- Dietary factors:
- Diets high in cholesterol, saturated and Trans fats.
- Diets high in carbohydrates.
- Diets high in calories.
- Diets low in fiber.
- Diets low in essential fatty acids.
- Sedentary life style and lack of physical activities.
- Stress.
- Medical conditions: diabetes, hypothyroidism, cholestasis, nephrotic syndrome, anorexia nervosa, Cushing’s syndrome, and hepatoma (liver tumor). Since the liver is the principle site of formation and clearance of lipids, liver diseases could have different impacts on lipid profiles. Hepatitis increases the level of TG slightly, while severe hepatitis and liver failure are associated with a significant decrease in the blood levels of cholesterol and TG due to a decrease in liver ability to synthesize lipoproteins.
- Medications: thiazides, cyclosporin, and tegretol.
- Alcohol and estrogen increase TG level. Estrogen and regular alcohol consumption increase both VLDL and HDL. Triglyceride level should be monitored in regular alcohol users, when taking birth control pills, and during postmenopausal hormone replacement therapy.
Potential causes of low level of HDL:
- Diabetes type II.
- Obesity.
- Smoking.
- Lack of exercise.
- Medical conditions: Gaucher`s disease.
- Medications: anabolic steroids, and beta-blockers.
- Malnutrition.

Recommended Foods:
- Drink plenty of water: at least 2 liters a day.
- Whole grains.
- Foods high in fiber: lentils, beans, avocado, oats, and artichoke.
- Foods high in omega-3: fish, flaxseeds, chia, and hemp seeds.
- Fruits and vegetables high in flavonoids: berries, red grapes, grapefruit, pomegranate, sea buckthorn, persimmon, kiwi, beets, basil, garlic, parsley, radish, radicchio, rhubarb and parsnips.
- Garlic.
- Onion.
- Foods with glycemic index less than 55 (See “Glycemic Index” under the section of “Carbohydrates“).

- Green tea.
- Maitake mushroom. It contains beta-D-glucan that lowers both LDL and TG.
- Soy products.
Recommended Supplements:
- Niacin (vitamin B3): 1000 – 3000 mg a day. Niacin lowers LDL and TG and increases HDL. The most frequent side effect of niacin is skin flushing, which is mediated by the release of prostaglandins D2 and E2. The skin flushing is a harmless but bothersome reaction that usually starts within 10 – 20 minutes after taking niacin and often lasts up to 30 minutes. Flushing can be reduced by one of the followings: 1) starting at lower doses and gradually increasing to higher doses, 2) taking no-flush or sustained-released forms, 3) taking 300 mg of aspirin about 30 minutes before taking niacin, 4) taking 200 – 400 mg of Advil per day, and 5) taking niacin along with meals. CAUTION: niacin should not be taken by people with peptic ulcer and liver disease. It can also raise uric acid level, increasing risk of attacks in gout, and fasting blood sugar level.

- Grape Seed Extract: 50 – 100 mg a day.
- Omega – 3 Fatty Acids: 3 – 4 grams a day. Omega-3 lowers TG level. It may increase LDL level in some patients and garlic supplement may prevent from this.
- Beta – Glucan: 3 – 10 grams a day. Beta-glucan is a type of fiber found in oats, barley, and maitake mushroom and can lower cholesterol.
- Co – Enzyme Q 10: 200 – 300 mg a day. It is a powerful antioxidant that can help lower cholesterol level.
