简要总结
The subjects of this intervention program are mainly based on community-dwelling mid-aged and older adults. The investigator's program will provide meals containing different proportionated protein.As this project is a double blind test, only the investigators will know which subject corresponding to specific group of diets.
Besides, the investigators use the valued-based healthcare standard set as well as the Center for Epidemiological Studies-Depression, Charlson's comorbidity index Montreal Cognitive Assesment ,and Mini Nutritional Assessment as outcome measures and to use the randomized controlled trial design to validate if increased protein density diet could improve the vitality and health of mid-aged and old adults .
详细描述
With aging, functions of every organs become to decline. Muscle mass, is one of the decline. According to previous research, adults would lose 40% among from aged 20 to 70. If muscle mass decline combining with the decline of muscle strength is so called Sarcopenia.When muscle mass decline, infectious risk gets higher, and resilience after illness gets lower. In addition, activity and life quality are also responsible for falling, cognitive difficulty, disability and mortality among seniors. We hope to find out the etiologies of Sarcopenia through this program and develop prevention strategy and model to mollify the the negative effect of rapid aging society.

盲法说明
The program is designed as a double blind test, randomized intervention. Which meant that neither the subjects nor the PI and co-PI would not know which kind of diet they're going to obtain. Only investigators and test provider would know the meals corresponding to respective groups of subjects.
