Impact of Increased Protein Density Diet to Muscle Mass and Strength Among Mid-aged and Older Adults
Impact of Increased Protein Density Diet to Muscle Mass and Strength Among Mid-aged and Older Adults
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 .
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.
