High intake of omega-6 fatty acids and fructose, combined with obesity, creates a chronic low-grade inflammatory state that increases susceptibility to and severity of COVID-19.

To reduce the risk of severe illness from respiratory infections, focus on reducing ultra-processed foods, sugary drinks, and seed oils. Prioritize whole foods, fruits, vegetables, and healthy fats to lower chronic inflammation, which is a key driver of disease severity.

ModerateSupportsMEDIUM confidence
Today's diet is high in omega-6 fatty acids and deficient in omega-3 fatty acids; this, along with a high fructose intake, leads to obesity, which is a chronic state of low-grade inflammation.
