Biography

Ailsa Welch is a Professor of Nutritional Epidemiology researching the effects of nutrition on aging, based at The University of East Anglia Medical School. Ailsa’s research focuses on understanding the protective factors in diet for musculoskeletal health (sarcopenia, loss of skeletal muscle mass and function with age), osteoporosis and fracture risk. She also researches into CVD and cancer, in developing dietary assessment methodologies, quantifying measurement error, and in evaluating public health improvement interventions. Ailsa’s research aims to understand the effects of micronutrients (vitamins & minerals) and diet quality (dietary patterns, fatty acids, protein & acid-base load) on musculoskeletal and cardiovascular health. Micronutrient malnutrition also co-exists alongside obesity and chronic disease.

Other more recent projects are investigating better methods for identifying malnutrition.  

Ailsa chaired the Nutrition & Lifestyle Forum of the National Osteoporosis Society and was a member of their Scientific Advisory Committee (2013-2019). She is also the scientific theme lead for Nutrition in the Treatment, Management and Prevention of Disease for the UK Nutrition Society. Ailsa chairs the initiative for ‘Optimising Nutrition and Hydration Practice in Care Homes’ and is a member of the Malnutrition Task Force.

Background

What is the study about?

As people get older their muscles get smaller and become weaker. Over time, this can make it more difficult to remain mobile and independent, which can affect the ability to carry out basic activities of daily living. One of the reasons that our muscles get weaker as we get older is that the mitochondria within muscles also age and work less efficiently. Mitochondria are like engines inside our muscles: they provide energy to fuel the movement of our bodies, and also other processes that occur within our muscles. As mitochondria age, they produce less energy and can also produce compounds called oxidants. Oxidants can cause inflammation and can damage our muscles and the mitochondria themselves.

Vitamin C is an antioxidant that we get from food. It may help to protect our muscles against the damage caused by oxidants, and may also help our mitochondria to work more efficiently. Researchers at the University of East Anglia want to investigate what effect vitamin C might have on muscle health, and on our mitochondria. This will help us to understand whether vitamin C may be useful for helping older people to remain mobile and independent for longer.

Who can take part?

We are looking for women aged 65 years or over, who have no major health conditions, to take part in this study. We are looking for women who eat less than 4 portions of fruit and vegetables per day; who do not take part in regular exercise; who do not smoke; and who are not currently taking vitamin C supplements.
