Excluding nutrition from mainstream healthcare has contributed to the catastrophic impact of SARS-CoV-2.


For too long nutrition has been dismissed by mainstream healthcare, despite clear evidence that diet and lifestyle choices either contribute to health or increased risk factors for chronic disease. The rising obesity epidemic is proof alone that a more decisive tactic is needed to combat the discord between public health and personalised lifestyle medicine, of which nutrition plays an integral part. As we enter the next wave of COVID-19 restrictions, is it now the time to consider the role nutrition can play in preventative healthcare?

“Long-term failure to provide adequate nutritional guidance to the public and a reliance on generic advice from Public Health England to pick up the shortfall, has undoubtedly contributed to the catastrophic impact of SARS-CoV-2”

notes BANT CEO Satu Jackson. BANT Nutrition Practitioners offer personalised nutritional guidance to individuals and rigorously recommend testing for nutrient deficiencies as part of a preventative strategy for chronic disease. The results of the government’s one-size-fits-all approach to healthcare is evident with obesity levels and metabolic dysregulation continuing to rise exponentially (1) and worsening health of the public now contributing to COVID-19 outcomes.

The emergence of data pointing to nutritional deficiencies in SARS-CoV-2 patients (2) highlights the need for a more unified approach. BANT recommends Vitamin C and D supplementation be considered as part of a preventative strategy for COVID-19 (2) where food sources are unable to adequately support the individual. BANT calls on the government to consider the nutritional status of the public as part of the current pandemic, and to engage with BANT to work towards building a more inclusive and effective healthcare model.

Compelling Evidence on Vitamin D status & severity of COVID-19 symptoms

Compelling Evidence on Vitamin D status and severity of COVID-19 symptoms prompt MP David Davis to speak out


“A cheap way of tackling COVID-19 is being ignored”

warns British MP and former cabinet minister David Davis in the face of mounting evidence that Vitamin D status reduces COVID-19 severity. BANT agrees that in the absence of an effective anti-viral therapy for COVID-19, a Vitamin D supplement regime should be extended to the general population, as a preventive measure to help mitigate the grave public health risks associated with COVID-19 infection.

Vitamin D insufficiency is common in northern countries throughout the winter months, with limited daylight hours and sun exposure. Whilst BANT recommends firstly sourcing nutrients through food, there are few natural foods containing adequate Vitamin D. This has been greatly aided by an increase in fortified foods, particularly in the dairy and cereal categories, however, they do not necessarily provide adequate therapeutic doses to support the immune system against infection. The evidence on the immune modulating effects of Vitamin D is nothing new. BANT Nutrition Practitioners often include Vitamin D testing, and where appropriate, supplementation in clinical practice. Public Health England recommend a daily supplement containing 10 micrograms Vitamin D during autumn and winter months (1).  Supplementation should be considered as part of a wider therapeutic protocol to optimise immune resilience and lower the risk factors associated with poor Vitamin D status in individuals.

Whilst Vitamin D is not a silver bullet, BANT warns that ignoring Vitamin D status is risking the outcomes of those most susceptible to COVID-19 infection. Optimising Vitamin D status can only be beneficial, especially to people who fall into this at-risk group. To this end, BANT urges the government to take decisive action and issue clearer guidance to the public.
