However, the benefits of a diet supplemented with phytosterol has been questioned.

Stigmastanol (sitostanol) is a phytosterol found in a variety of plant sources.

Campesterol is a phytosterol whose chemical structure is similar to that of cholesterol.

Health Canada concluded that sufficient scientific evidence exists to support a relationship between phytosterol consumption and blood cholesterol lowering.

Health Canada reviewed the evidence of 84 randomized controlled trials published between 1994-2007 involving phytosterol supplementation.

Cholesterol-lowering efficacy of a sitostanol-containing phytosterol mixture with a prudent diet in hyperlipidemic men.

Muldamine is a phytosterol alkaloid isolated from Veratrum californicum.

This weed contains the phytosterol saringosterol that shows an inhibitory effect on Mycobacterium tuberculosis growth.

Modulation of plasma lipid levels and cholesterol kinetics by phytosterol versus phytostanol esters.

The most common plant stanols in the human diet are sitostanol and campestanol, which combined make up about about 5% of dietary phytosterol.

Nuts, which are rich in phytosterols, are often eaten in smaller amounts, but can still significantly contribute to total phytosterol intake.

The primary concern regarding conventional phytosterol supplementation is the effect it may have on the absorption and circulating levels of lipid soluble vitamins.

Also, Professor Schleimer had similarly been collaborating with me in the detection of phytosterol in mixtures of animal and vegetable fats.

Studies have indicated that consumption of about 2 grams per day of phytosterol esters provides a reduction in LDL cholesterol of around 10%.

When intestinal lining cells absorb phytosterols, in place of cholesterol, they usually excrete the phytosterol molecules back into the GI tract, an important protective mechanism.

The link between plant sterols and CVD or CHD risk is complicated because phytosterol levels reflect cholesterol absorption.

Vayarol is a formulation of phytosterol esters of omega 3 which was developed by VAYA Pharma (division of Enzymotec LTD), a specialty pharmaceutical company.

Stanol esters are a heterogeneous group of phytosterol esters with a saturated sterol ring structure known to reduce the level of low-density lipoprotein (LDL) cholesterol in blood when ingested.

Klippel KF, Hiltl DM, Schipp B. A multicentric, placebo-controlled, double-blind clinical trial of beta-sitosterol (phytosterol) for the treatment of benign prostatic hyperplasia.

A potential safety concern regarding phytosterol consumption is in patients with phytosterolaemia, a rare genetic disorder which results in a 50- to 100-fold increase in blood plant sterol levels and is associated with rapid development of coronary atherosclerosis.

Olive oil is composed mainly of the mixed triglyceride esters of oleic acid and palmitic acid and of other fatty acids, along with traces of squalene (up to 0.7%) and sterols (about 0.2% phytosterol and tocosterols).

The FDA also concluded that a daily dietary intake of 2 grams a day of phytosterols (expressed as non-esterified phytosterols) is required to make an authorized health claim relating phytosterol consumption to cholesterol lowering and CVD risk.

When reviewing clinical trials involving phytosterol supplementation, the FDA concluded that when consumed in the range of 1 to 3 grams in enriched foods, phytosterols resulted in statistically significant (5-15%) reductions in blood LDL cholesterol levels relative to placebo.

Acacias contain a number of organic compounds, e.g. amines and alkaloids, cyanogenic glycosides, cyclitols, fatty acids and seed oils, fluoroacetate non-protein amino acids, terpenes (including essential oils, phytosterol and saponins), tannins, flavonoids, Flavanoid, coumarin, steroid and terpene, are collectively known as the aglycone.
