TI  - Relationship of dietary habits and obesity to oxidative stress in Palauan people: 
      compared with Japanese and Mongolian people.
PG  - 214-22
AB  - The Republic of Palau belongs to Micronesia, and obese people and 
      lifestyle-related diseases are prevalent there. We investigated the relationship 
      of dietary habits and obesity to oxidative stress in Palauan people, as compared 
      with those of Japanese and Mongolian people. A total of 126 healthy Palauan 
      subjects were enrolled. Oxidative stress was evaluated by serum level of reactive 
      oxygen metabolites (ROM). Antioxidant capacity was evaluated by serum level of 
      biological antioxidant potential (BAP). In Palauan subjects, BMI> or =30 was 
      observed in 45.0% of males and 59.1% of females (Japanese: males 1.3%, females 
      0.8%, Mongolian: males 6.3%, females 14.7%). Palauan subjects consumed 2553 kcal 
      per day (Japanese 2121 kcal, Mongolians 2534 kcal). The ratios of carbohydrate 
      energy to total energy were 59.8 % (Japanese 54.7 %, Mongolians 50.2%). The 
      ratios of fat energy to total energy were 22.9% (Japanese 26.7%, Mongolians 
      34.5%). ROM levels in Palauan subjects showed higher than those in Japanese 
      subjects, while BAP levels of Palauan subjects did not decrease compared to those 
      of Japanese. ROM levels correlated with body fat ratio, and showed a reverse 
      correlation with handgrip strength. Handgrip strength decreased in the subjects 
      of more than forty years of age. These findings suggest that the obesity in 
      Palauan people may have a connection with high intake of calories through 
      carbohydrate eating rather than through fat eating. Their high oxidative stress 
      may be induced by obesity, and contribute to an early decline of handgrip 
      strength, ultimately in early aging.
