Altered Cholesterol and Lipid Synthesis Mediates Hyperinflammation in COVID-19.

Recent data have revealed that fructose-rich diet triggers inflammation and lipid synthesis. Furthermore, lipid metabolism, cholesterol synthesis and sterol regulatory element binding protein-2 (SREBP-2) activation correlates with coronavirus disease 2019 (COVID-19)-induced cytokine storm. High fructose consumption result in SREBPs activation, altered cholesterol and lipid synthesis and may establish an innate immune memory in the cells, leading to severe COVID-19 in patients with obesity.
