24 Jul 2021 Nutrition Evidence Alert – July 2021 – COVID-19 & Long COVID
Welcome to the July edition of the Nutrition Evidence Alert.
Emerging evidence and patient testimony suggest that a proportion of individuals testing positive for COVID-19 will experience on-going and long term symptoms, well after the acute infection is over. The NICE guideline scope produced in the latter part of 2020 defines long COVID as symptoms consistent with COVID-19 infection which persist for 12 weeks or longer. The Office for National Statistics using self-reported data estimates that close to 1 million people in the UK are suffering with long COVID.
Symptoms of Long COVID are many and varied. Individuals may be affected with extreme fatigue, brain-fog, shortness of breath, chest pain, joint pain, depression and anxiety, tinnitus and more. A recent publication by the NHS provides the full list of reported symptoms, and includes plans for publicly funded treatment and rehabilitation.
Our Guest Editor this month, Karen Preece-Smith, brings to our attention the latest evidence on Long COVID and nutrition. Given the newness of this condition, there is limited research data, however some interesting reviews are being conducted on the role of nutrition, dietary antioxidants, immune rejuvenation and mitochondrial function. This area of research will be one to watch over the coming months for insights into possible clinical interventions.
