Abstract

生姜抽出物の経口摂取による人でのエネルギー消費等を,冷え性気味の健常若年女性19人を対象としたランダム化交差比較試験により検討した.被験者は室温23~24℃,湿度30~40%の環境下において,(1)プラシーボ(澱粉),(2)生の生姜10 g相当,(3)生の生姜20 g相当をそれぞれ別の日にカプセルで摂取した.サンドイッチと適量の水をとった後,カプセルを飲み,1時間,2時間,3時間経過時に,エネルギー消費量,手と足の指先の体表温,脈拍数および収縮期・拡張期血圧の測定を行った.その結果,食事による影響を取り除いた生の生姜10 g相当摂取時は安静時に対する増加率で,1時間後7.4%,2時間後8.2%,3時間後6.6%で,1時間後を除いて有意な増加であった.また,生の生姜20 g相当摂取時のエネルギー消費量は1時間後10.5%,2時間後11.6%,3時間後8.6%と有意に増加した.結論として,人での研究において,生姜非摂取時に比べ,生姜摂取によってエネルギー消費量が有意に高まることが初めて明らかになった.

The present study was designed to investigate the effects of pungent components of ginger on the energy consumption, temperatures at some body parts, pulse rates and blood pressures in 19 young women with chilliness of their hands and feet. Under the conditions of 23∼24°C in temperature and 30∼40% in humidity, subjects took four capsules containing (1)placebo (starch only), (2)ginger extract equivalent to raw ginger 10 g, or (3)ginger extract equivalent to raw ginger 20 g with a sandwich and <i>ad-lib</i> water in different days. Energy consumption, temperatures at the tips of finger and toe, pulse rates, and blood pressures were measured at 1 hour, 2 hours and 3 hours after the intake. Energy consumption was calculated from O<sub>2</sub> consumption, CO<sub>2</sub> expenditure, and respiration quotient by a metabolic analyzer. As the results, intake of ginger extract equivalent to raw ginger 10 g generated 7.4%, 8.2% and 6.6% increases at 1 hour, 2 hours and 3 hours after the intake as compared with that of the resting (control) condition. And intake of ginger extract equivalent to raw ginger 20 mg generated 10.5%, 11.6% and 8.6% increases in energy expenditure at 1 hour, 2 hours and 3 hours after the intake. In conclusion, this study first elucidated the quantitative effect of pungent components of ginger on energy consumption in humans.
