7 J Jpn Soc Nutr Food Sci 56 : (2003) Effects of Ginger and Its Effective Components on Energy Expenditure in Rats Momoe Iwami,1 Sumire Terada,1Midori Sunahara,1 Rie Shimooka,1 and Takashi Shimazu*,1 (Received September 9, 2002 ; Accepted January 22, 2003) Summary : We examined the effects of ginger and its effective components, zingerone and zingerol (reduced form of zingerone), on oxygen consumption (VO2) and respiratory quotient (RQ) in rats fed a highcarbohydrate diet or a high-fat (lard) diet. Addition of 2% ginger powder to the high-carbohydrate and high-fat diets caused significant (approximately 7%) and insignificant (6%) increases, respectively, in 12-h cumulative VO2 during the dark (feeding) period. The RQ values during the period were reduced significantly by the addition of ginger to both diets. Similar effects on VO2 and RQ were also observed when, for comparison, 2% red pepper was added to the diets. We next examined the effects of zingerone, the major pungent component of ginger. Addition of 0.4% zingerone to the high-fat diet resulted in a marked increase in 12-h cumulative VO2, a smaller increase in VO2 being obtained by zingerone supplementation to the high-carbohydrate diet. The RQ values were also decreased by zingerone in both diet groups. On the other hand, addition of 0.4% zingerol, the non-pungent reduced form of zingerone, had little effect on VO2 or RQ. However, when zingerone and zingerol were added simultaneously, the cumulative VO2 was increased markedly and synergistically (about 30%) in both diet groups, with significant decreases in RQ. These results indicate that ginger and its pungent component zingerone have stimulatory action on energy expenditure by increasing oxygen consumption and accelerating the combustion of bodily fat. Key words : ginger, zingerone, zingerol, oxygen consumption, respiratory quotient * Corresponding author 1 Department of Nutrition and Food Science, Faculty of Human Life Science, Hiroshima Jogakuin University, Ushita-higashi, Higashi-ku, Hiroshima , Japan
