Plant-based diets, pescatarian diets and COVID-19 severity: a population-based case–control study in six countries

A population-based case-control study in six countries was recently conducted to investigate the association between dietary patterns and COVID-19

Quick takes:

  • Prior studies suggest a connection between comorbidities and the severity of COVID-19
  • The aetiology of non-communicable diseases like obesity, type 2 diabetes, CVD, and hypertension, each of which considered a risk factor associated with COVID-19 severity, is largely driven by poor nutrition and unfavourable lifestyle choices
  • In six countries, following plant-based or pescatarian diets were associated with lower odds of moderate to severe COVID-19 severity
  • Those consuming low-carbs high protein diets were more susceptible to COVID-19 severity
  • Plant-based or pescatarian dietary patterns may be considered for protection against severe COVID-19 and duration of symptoms
