通过改变蔗糖和玉米糖浆固体的量，在保持相同的卡路里、蛋白质和电解质水平的同时，将液体饮食的渗透压摩尔浓度从250 mOsm/kg变化至700 mOsm/kg。在猪自愿食用标记有3 H2O和U-14 C-蔗糖的五种饲料之一后的4小时内，监测血浆中3 H和14 C的出现。血浆渗透压和钠和钾浓度在血浆中没有不同的饮食。餐后血糖浓度对饮食的反应在治疗之间和治疗内都不同。血浆中放射性示踪剂的出现率表明，随着饲料渗透压升高至700 mOsm/kg，水和碳水化合物的吸收加速。
Osmolality of a liquid diet was varied from 250 to 700 mOsm/kg by altering the amount of sucrose and corn syrup solids, while maintaining the same level of calories, protein, and electrolytes. The appearance of 3H and 14C in blood plasma were monitored during a 4-h period after pigs voluntarily consumed one of five diets labeled with 3H2O and U-14C-sucrose. Plasma osmolality and sodium and potassium concentrations in plasma did not differ among the diets. Postprandial plasma glucose concentration response to the diets varied both between and within treatments. The rates of radioactive tracer appearance in plasma suggest that water and carbohydrate absorption were accelerated with increasing osmolality of diet up to 700 mOsm/kg.
