A deficiency in zinc can leave you more susceptible to infections and illnesses, including respiratory viruses and other diseases.
Pair insufficient zinc status with potentially elevated genetic risk for the flu (as reviewed in yesterday’s post!) and this winter could be a high risk season for your immune system!
⠀
Why Zinc Matters:
T-Cell Function: Zinc plays a key role in supporting T-cells, a critical part of your immune system that fights viruses and bacteria. Without enough zinc, T-cell function declines, especially as we age.
Thymus Health: The thymus (a small organ responsible for T-cell development, shrinks with age) a process called thymic involution. Zinc supplementation has been shown in animal studies to improve thymus size and T-cell function.
⠀
Illnesses Linked to Zinc Deficiency:
Respiratory Viruses: Zinc inhibits viral replication in rhinoviruses (common cold) and influenza, while clinical trials have shown its benefits in reducing pneumonia by 41% and diarrheal illnesses by 18%.
⠀
COVID-19: Studies reveal that patients with severe COVID-19 often have lower zinc levels, with more than half experiencing deficiency.
⠀
Hepatitis C: Zinc reduces this virus by inhibiting its RNA replication.
⠀
Why Regular Zinc Intake Is Crucial:
Your body doesn’t store zinc, meaning you need a steady dietary supply. Unfortunately, over 1 billion people worldwide are zinc deficient, with some estimates suggesting a third of the global population may be affected.
⠀
Top Zinc-Rich Foods:
-Oysters
-Crab
-Beef
-Elk, lamb, and bison
-Certain mushrooms
-Fortified cereals
