自从Rubner提出了“食物的特殊动力作用”的概念,用以反映人体进食过程中能量的额外消耗现象(约占日需能量的10%,实测其中碳水化合物在5～6%,脂肪在6%,蛋白质在20%)。后来有人推测其为胃肠道蠕动、消化、吸收食物养分时所耗能量。近来,各国生理学家均证明:经静脉补充液体营养物质(非消化道摄入),机体额外消耗能量同经消化道摄入食物时消耗的能量相当,约870KJ/天(70kg体重成人安静状态下日需热量约8700KJ)。新的研究认为:“特殊动力作用”为
Since Rubner proposed the concept of “special dynamic effects of food” to reflect the extra consumption of energy during human eating (about 10% of the daily energy requirement, of which carbohydrates are between 5 and 6% and fat content is between 6%, protein at 20%). Later it was speculated that it is gastrointestinal motility, digestion, absorption of food nutrients consumed energy. Recently, physiologists all over the country have proved that: the intravenous supplement of liquid nutrients (non-gastrointestinal intake), the body extra energy consumption with the food consumed by the alimentary canal when the energy consumption of about 870KJ / day (70kg weight adult quiet state Daily needs about 8700KJ heat). New research suggests: “special dynamic ” for
