Abstract:
Phytosterols are isoprene compounds that may be found in a great variety of different food products. The most important phytosterol compounds are β-sitosterol, campesterol and stigmasterol. Plant sources of phytosterols are oily seeds, nuts, plant oils, grains, and pulses. Many controlled clinical studies have demonstrated their ability to reduce blood cholesterol levels in hyper- and normocholesterolaemic subjects. Investigators report that phytosterol intakes of 2 to 3 g/d reduce low-density lipoprotein (LDL) cholesterol levels by about 7–11% in human subjects, while LDL and TG levels do not

Abstract:
Abstract Most clinical phytosterol studies are performed by adding purified supplements to smaller phytosterol amounts present in the natural diet. However, natural dietary phytosterols themselves may also have important effects on cholesterol metabolism. Epidemiological work using food frequency questionnaires to estimate dietary intake suggest that extremes of normal consumption may be associated with 3–14% changes in LDL cholesterol. Standardized food databases do not have enough phytosterol values to allow calculation of phytosterol intake for individuals outside of specialized studies. Na

Phytosterols has been known for its cholesterol lowering action long time back but the uprising of phytosterols in form of functional foods gained the interest once again. Fatty food matrix provides optimal solubility but fortification of phytosterols with other food matrices like low fat fermented milk, bread, juice are showing positive results.

Abstract Objectives Breast cancer is the most diagnosed form of cancer among American women. Worldwide, it is second only to lung cancer. Phytosterols are phytochemicals found in plant foods that have potential benefits for breast cancer.

Abstract:
Localised accumulation of body fat significantly influences the development of obesity related co-morbidities and cardiovascular disease (CVD) risk. Medium chain triglycerides (MCT) have been suggested to modulate body fat distribution. Phytosterols (PS) have demonstrated unequivocal cholesterol-lowering effects. A healthy dietary solution combining MCT and PS could thus become first-line obesity and CVD prevention. The aim of this study was therefore to investigate the effects of a functional oil (FctO) rich in MCT and PS on blood lipid levels and body adiposity, compared to olive oil.

Cardiovascular disease (CVD) risk can be lowered by introduction of plant sterols (PS) in the diet, since PS have been shown to reduce low-density lipoprotein cholesterol (LDL-C). Given that the efficacy of PS as cholesterol-lowering agents depends on their appropriate solubilization, the cholesterol-lowering efficacy of PS in non-traditional matrices needs to be determined. The primary aim of this thesis was to examine the consumption of PS (a) in an oil rich in medium chain triglycerides (MCT) or (b) low-fat yogurt with or without a meal, on changes in lipid parameters.

Abstract:
Phytosterols and phytostanols are a large group of compounds that are found exclusively in plants. They are structurally and functionally related to cholesterol but differ from cholesterol in the structure of the side chain. Phytosterols lower total and low-density lipoprotein (LDL) blood cholesterol by preventing cholesterol absorption from the intestine, so they have been known as blood cholesterol-lowering agents. Phytosterols are naturally found in fruits, vegetables, nuts, and mainly oils. Dietary phytosterol intakes normally range from 160-400 mg/day with variations depending on food culture and major food sources. Dairy foods remain a food of choice for use as delivery vehicle for many functional ingredients including phytosterols and there are many dairy products available in the global markets which are enriched with phytosterols. The use of phytosterols in commonly consumed dairy products may soon provide an effective tool against CVD and its introduction to our food products is worth anticipating in the near future as nutraceuticals for healthy ageing.
