Adding Years to Life and Life to Years

Research Impact Case Study – Adding Years to Life and Life to Years: Nutrition Supports for Age Related Muscle Mass Loss

Research Impact - Adding years to life and life to years_Page_1In Ireland, only 30% of women and 45% of men over 65 remain disability-free for life. Dramatic changes in cells start in our 30s, while in our 40s, health and functionality are impacted by increasing weight gain, decreasing bone density and loss or weakening of muscle. People with low lean tissue or muscle mass are classified as sarcopenic. Conservative estimates predict that the incidence of sarcopenia will increase by 50% over the next 30 years, making it a major public health issue among Ireland’s increasing older population.

In the case study, Prof Phil Jakeman and Dr. Catherine Norton discuss their research which has proven that that sarcopenia can be offset by modifications to dietary habits. Their research shows that optimising the quality and timing of protein intake decreases age-related loss of muscle mass and in turn can benefit the quality of life of those who are affected by sarcopenia.  In addition, the team have collaborated  with industry to commercialise nutrient supports that reduce age-related loss of muscle mass. This research has the potential to not only improve quality of life for seniors but also has significant economic implications.  Read the Full Case Study here
