因此,在植物性食品中,在健康人的血清和组织中发现的浓度比内源性胆固醇低800 - 1000倍。谷甾醇的糖苷(谷甾醇)在哺乳动物血清中的浓度甚至更低。在许多动物体内,谷固醇和谷固醇素相对于胆固醇的浓度比人类高得多。只有植物可以合成这些化合物,人类和动物从他们的饮食中获得它们。尽管它们的吸收效率很低(谷甾醇和谷甾醇相对于胆固醇的吸收效率分别为-1/10和-1/50),但它们对免疫系统的明显协同刺激作用和对各种文明疾病的预防作用表明它们在人类和动物营养中的重要性。由于现代食品加工往往会减少它们在加工过的植物性食品中的浓度,而饮食习惯也会对它们的消费产生不利影响,因此最好食用足够的未精制或未加工的植物性食品,或求助于含有谷甾醇和谷甾醇的食品补充剂。
and hence in plant-derived food poducts, is found in the serum and tissues of healthy humans in concentrations 8001000 times less than the endogenous cholesterol. The glucoside of sitosterol (sitosterolin) is present in mammalian serum at even lower concentrations. In many animals, sitosterol and sitosterolin concentrations relative to cholesterol are considerably higher than in humans. Only plants can synthesise these compounds and humans and animals obtain them from their diet. Even though their absorption efficiency is low (-1/10 and -1/50 for sitosterol and sitosterolin, respectively, relative to cholesterol), their apparent synergystic stimulatory effect on the immune system and prophylactic effect on a variety of diseases of civilisation indicates their importance in human and animal nutrition. Since modern food processing tends to reduce their concentration in processed plant-food products, and eating habits also affect their consumption adversely, it is desirable to eat sufficient unrefined or unprocessed plant foods or resort to food supplements containing sitosterol and sitosterolin.
