Not Applicable

Conditions

Interventions
Dietary Supplement: 15% protein
Dietary Supplement: 25% protein
Registration Number
NCT03784456
Lead Sponsor
National Yang Ming Chiao Tung University
Brief Summary

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 .

Detailed Description

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.

15% protein group15% proteinThis control arm will be given meals containing 15% protein under same estimated calorie menus and protein may come from either egg, meat, fish, soy, or milk product. The meals would be provided 2 times per day, 5 days per week. The program will last for 12 weeks.
25% protein group25% proteinThis experimental arm will be given meals containing 25% protein under same estimated calorie menus and protein may come from either egg, meat, fish, soy, or milk product. The meals would be provided 2 times per day, 5 days per week. The program will last for 12 weeks.
