FOODS TO SUPPORT YOUR IMMUNE SYSTEM DURING COVID-19

IMG_9337

Summary: 

  • Garlic
  • Shallot
  • Citrus fruits (blood orange>orange>lemon>lime>grapefruit)
  • Peppermint
  • Nettle tea
  • Cinnamon
  • Green tea

Mannose Binding Lectins:

These proteins potentially stick to the S proteins on the surface of the virus. This activates the innate immune system to attack the virus. It may also block the virus from binding to ACE2 to enter the cells. 

  • Griffithsin (Red algae)
  • Garlic
  • Shallot
  • Chive

ACE2 Binders (only studied in vitro): 

S proteins on the virus bind to ACE2 on the surface of the lung cells, which results in entry into the cell.

  • Chinese skullcap 
  • Hesperetin (blood oranges, lemon, lime, grapefruit)
  • Soy
  • Licorice root
  • Astragalus
  • Stinging nettle
  • Andrographis
  • Sambucus

Serine protease inhibitors:

This is a co-enzyme needed for the ACE2 enzyme to function in allowing viral entry into the cell.

  • Garlic
  • Milk thistle
  • Quercetin

Endocytosis inhibitors:

This is when the viral envelope fuses with our cell membrane, spilling the viral genome into our cell.

  • Cinnamon
