Beta-Sitosterol Reduces Cholesterol Levels in Patients with cystic fibrosis

Cholesterol is a waxy substance that is produced either by the liver or injected from animal food sources.

Cholesterol found in our body is needed for our body to build cell walls, hormones, and vitamin D, and create bile salts that aid digestion. However, too much of them, in most cases due to the intake of animal protein can cause plaques built up on the arterial wall, the major cause of heart disease and stroke.

More precisely, if levels of low-density lipoprotein are high compared to high-density lipoprotein which returns the accessed cholesterol back to the liver, you have high blood cholesterol.

In other words, healthy blood cholesterol is any level with either less than or equal to 4 (low-density lipoprotein/ 1 (high-density lipoprotein).

According to the statistics, in 2015-2016, by age and gender, a total of 12.4 percent of adults aged 20 years and over had high cholesterol in the United States.

The ideal blood cholesterol is less than 4 (levels of LDL)/ 1(levels of HDL).

Low-density lipoprotein is needed for our body to build cell walls, make hormones and vitamin D, and create bile salts that help to digest fat. However, overexpression of LDL can induce plaque accumulated on the arterial wall, leading to atherosclerosis, a major cause of cardiovascular disease.

Low-density lipoprotein is produced by the liver or from the dietary sources. High-density lipoprotein neutralizes the levels LDL by returning them to the liver.

Some researchers suggested that Diet high in trans fats, saturated fat, sugar, smoking, medical conditions such as diabetes or high blood pressure are associated with the increased risk of high blood cholesterol.

Cystic fibrosis (CF) is the most common fatal genetic disease affecting mostly the lung in children and young adults, leading to difficulty breathing and coughing up mucus due to frequent lung infections.

However, the condition has also been found in the pancreas, liver, kidneys, and intestine.
According to the Cystic Fibrosis Foundation Patient Registry, more than 30,000 people are living with cystic fibrosis in the US.

Believe it or not, most cases of CF are diagnosed by age 2.

Beta-Sitosterol is a phytochemical in the class of Phytosterols, belongings to the group of Lipids, found abundantly in avocados, rice bran, wheat germ, corn oils, fennel, peanuts, soybeans, hawthorn, basil, buckwheat. etc.

On finding a potential phytochemical for the prevention and treatment of diseases associated with hyper cholesterol, researchers elucidated the β-sitosterol effects in the plasma of patients with cystic fibrosis (CF).

The study included the plasma of 26 patients with CF and 33 unaffected controls that are treated by β-sitosterol and campesterol, using gas chromatography (GC-FID and GC-MS) assays.

Before the administration of β-sitosterol, the plasma level of cholesterol is higher in patients with CF compared to control subjects.
* Furthermore, plasma cholesterol treated by β-sitosterol was significantly lower in CF patients, compared to control.

* Moreover, β-sitosterol prevent the impaired intestinal absorption of exogenous sterols in patients with CF that stimulates the endogenous synthesis of cholesterol, without affecting the total cholesterol in plasma.


In other words, cystic fibrosis induced transmembrane conductance regulator (CFTR) dysfunction reduces cholesterol blood excretion causing the accumulation of cholesterol in liver cells and in other tissues that CF chronic inflammation.

Taken altogether, beta-Sitosterol may be considered a supplement for the prevention and treatment of hyper cholesterol in patients with CF, pending to the confirmation of the larger sample size and multicenter human study.

Intake of beta-Sitosterol in the form of supplements should be taken with extreme care to prevent overdose acute liver toxicity.
