”Longevity” is everyone’s wish, but how can it be achieved? A survey of 402 100-year olds in 7 longevity regions in China has come up with a food and behavior profile of the long-lived elderly, which may give you some insight. The survey was funded by the National Natural Science Foundation of China and jointly conducted by the China Center for Disease Control and Prevention and Peking University. The survey included all elderly people over 100 years old, including 339 women, in Xiyi County, Henan Province, Laizhou City, Shandong Province, Zhongxiang City, Hubei Province, Mayang County, Hunan Province, Sanshui District, Foshan City, Guangdong Province, Yongfu County, Guangxi Zhuang Autonomous Region and Chengmai County, Hainan Province. The survey randomly matched 434 younger seniors (60 to 79 years old) and 726 senior seniors (80 to 99 years old). The survey was conducted through household interviews and other means to understand the dietary patterns and behavioral lifestyles of the survey respondents. Among them, dietary pattern mainly refers to the frequency of consumption of soy products, vegetables, fruits, meat, dairy, eggs and fish; behavioral lifestyle mainly includes smoking, drinking and tea drinking. The survey also collected the disease conditions of hypertension, diabetes, cardiovascular diseases and respiratory diseases among the long-lived elderly. The survey found that the dietary patterns and behavioral lifestyles of centenarians had three more distinctive features: 1. a lower proportion of vegetables consumed by centenarians; 2. a lower proportion of smoking among male centenarians; and 3. a better food diversity among centenarians than among senior citizens. Among the various physical examination indicators, centenarians have lower diastolic blood pressure and triglycerides and higher cholesterol, high-density cholesterol and urea nitrogen. The low rate of vegetable consumption among centenarians may be related to the reduced chewing and digestive functions of the elderly; the insistence of centenarians on food diversity has enabled the elderly to have lower diastolic blood pressure and better lipid profile, and fewer male centenarians smoke, which may be one of the secrets to the longevity of these centenarians.
