Relative efficacy of plant sterols, stanols, steryl esters and stanyl esters in lowering serum cholesterol in humans

Alfred Wong, Xymega Corporation, Vancouver, Canada

Abstract. Plant sterols, stanols, steryl esters and stanyl esters are generally recognized to provide significant lowering of LDL-cholesterol in humans. There are various compositional-related factors which could affect their comparative performances. Analysis of presently available published data suggests free-form stanols to be the most efficacious.(AK20121W)

Novel naturally-occurring compounds which could alleviate HIV/AIDS-related cahexia in humans

Abstract. Laboratory animal tests have shown that the intake of estrone, in the form of esters, can induce significant increases in body weight, without changing the basic proportion of protein, lipid and water. Estrone and estrone esters are present in small amounts in many commonly consumed foods. The fortification of foods with this class of anti-cachexic chemicals, could be an effective means to provide HIV/AIDS-infected persons with improved health to retard the on-set and progression of wasting. For those HIV/AIDS persons with advanced wasting, this nutritional approach would provide at least some comforting palliative care in the final days. (AK22565W)

Reversing the high prevalence of obesity, diabetes, hypertension and depression among the aboriginal people

Al Wong, Xymega Corporation, Vancouver, Canada

The prevalence of obesity, Type II diabetes, hypertension and depression is exceptionally high among the aboriginal people, in comparison to the Canadian population at large. These chronic diseases are interlinked. Insulin resistance, one of the principal underlying causes of Type II diabetes, is generally deigned as a reduction in the ability of insulin to regulate glucose metabolism. Insulin resistance is an adaptation of the state of obesity of a person. Reduction of obesity, viz., body fat, would thus be an effective strategy to remedy the conditions of Type II diabetes, hypertension and depression. (AK25306W)

Thermal stability of phytosterols

Abstract. Thermal stability is an important determinant on the suitability of phytosterols for use in the preparation of processed foods. Formation of cyto-toxic sterol epoxides would be an undesired outcome of oxidation of phytosterol under heated conditions. Several experimental and commercial samples of phytosterols were tested for their thermal stability in laboratory experiments. Preliminary test results suggested that a small amount of epoxides were formed for certain grades of phytosterols, under the experimental conditions of 90 degrees Celsius. Saturated phytosterols, i.e., phytostanols, were found to be most stable. (AK20304W)
