Cardiovascular disease (CVD) is the Nation's leading killer for both men and women among all racial and ethnic groups. Development and progression of CVD is linked to the presence of risk factors such as hyperlipidemia, hypertension, obesity, and diabetes mellitus. It is known that cholesterol is an indicator of increased risk of heart attack and stroke. Low-density cholesterol (LDL) above 130 mg/dl high-density cholesterol (HDL) cholesterol below 35 mg/dl and total blood cholesterol above 200 mg/dl are indicators of problematic cholesterol. Proper ranges of cholesterol are important in the prevention of CVD. It has been suggested that a reduction in the consumption of saturated and an increase in unsaturated fatty acids is beneficial and prevents CVD. Amaranth grain contains tocotrienols and squalene compounds, which are known to affect cholesterol biosynthesis. The cholesterol precursors squalene, lanosterol and other methyl sterols, reflect cholesterol synthesis 123, whereas plant sterols and cholestanol, a metabolite of cholesterol, reflect the efficiency of cholesterol absorption in normal and hyperlipidemic populations 456. Qureshi with co-authors 7 showed that feeding of chickens with amaranth oil decreases blood cholesterol levels, which are supported by the work of others 8. Previously, we have shown that Amaranth oil modulates the cell membrane fluidity 9 and stabilized membranes that could be one reason as to why it is beneficial to those who consume it. It is known that in hypertension, the cell membrane is defective and hence, the movement of the Na and K ions across the cell membranes could defective that could contribute to the development of increase in blood pressure. Based on these properties of amaranth oil we hypothesize that it could be of significant benefit for patients with CVD.
心血管疾病(CVD)是美国所有种族和族裔群体中男性和女性的主要杀手。CVD的发展和进展与高脂血症、高血压、肥胖症和糖尿病等危险因素的存在有关。众所周知,胆固醇是心脏病发作和中风风险增加的指标。低密度胆固醇(LDL)高于130毫克/分升、高密度胆固醇(HDL)低于35毫克/分升以及总血胆固醇高于200毫克/分升是胆固醇问题的指标。胆固醇的适当范围对预防CVD很重要。有人提出,减少饱和脂肪酸的摄入并增加不饱和脂肪酸的摄入是有益的,并可预防CVD。苋菜籽含有生育三烯酚和角鲨烯化合物,已知它们会影响胆固醇的生物合成。胆固醇前体角鲨烯、羊毛甾醇和其他甲基甾醇反映胆固醇合成,而植物甾醇和胆固醇代谢物胆甾烷醇反映正常和高脂血症人群中胆固醇的吸收效率。Qureshi及其合著者表明,用苋菜油喂养鸡可降低血液胆固醇水平,其他人的研究也支持这一结果。此前,我们已经表明,苋菜油可调节细胞膜流动性并稳定细胞膜,这可能是它对食用者有益的一个原因。众所周知,在高血压中,细胞膜存在缺陷,因此,钠和钾离子跨细胞膜的移动可能存在缺陷,这可能导致血压升高。基于苋菜油的这些特性,我们假设它对CVD患者可能有显著益处。
