The novel 2019 Coronavirus is a new rapidly spreading virus which causes respiratory infections in people, with signs ranging from fever, persistent cough, shortness of breath, breathing difficulties and other respiratory symptoms. With the worldwide outbreak of this new coronavirus disease – the COVID-19, and the daily rise in cases internationally, the World Health Organization (WHO) declared its spread as a global pandemic. The younger population with a healthy immune system are at lower risk and generally experience mild impacts of the disease, older people and those with underlying health conditions such as heart disease, lung disease, diabetes, high blood pressure and cancer, who have a compromised immune system are at high risk of COVID-19.

As the death toll climbs to over 9000 and more than 2,20,000 tested positive for the coronavirus infection, you might be worried about how it could affect your life and what steps should be taken at your end. Prevention is the priority at this time!

Diet and Nutrition : Anti-viral and Immune-Boosting Foods to fight against infections like Coronavirus


Take care of your diet and nutrition : Boost your immune system and prepare your body to fight against viral infections such as coronavirus!


1. Shikimic Acid containing Foods (eg : Star Anise)

Including the popular spice Star anise in your diet will be helpful as it is rich in Shikimic acid, a compound with strong antiviral properties. Shikimic acid is an active ingredient of an anti-viral medication used to treat and prevent infections such as influenza A and influenza B.(Patra JK et al, Phytother Res. 2020)

2. Lectin Rich Foods (eg : Leek, Garlic, Onion etc)

Lectins are proteins which bind to carbohydrates and are found in different varieties of food including :

  • fruits and vegetables such as leek, garlic, onion, jackfruit and banana; 
  • legumes such as peanuts and kidney beans;  and 
  • grains such as wheat. 

Lectins can inhibit the replication of viruses by interacting with the viral envelope glycoproteins (carbohydrate bound proteins) leading to the clumping of viruses and preventing them from infecting our cells. Different plant lectins such as lectin isolated from leek called APA, have strong antiviral properties and are potent inhibitors of coronavirus (Keyaerts E et al, Antiviral Res. 2007). 

3. Zinc Supplements and Quercetin Rich Foods (Beet Greens, Peppers, Greek Yogurt etc)

In vitro studies show that Zinc inhibits coronavirus RNA polymerase activity and blocks viral RNA replication; hence consuming zinc supplements and zinc rich foods will be beneficial in fighting viral infections and diseases. (Aartjan J. W. te Velthuis et al, PLoS Pathogens, November 2010)

Zinc rich foods include:

  • Pumpkin Seeds
  • Chickpeas
  • Black Beans
  • Beet Greens
  • Greek yogurt
  • Cashews
  • Cheddar cheese
  • Oysters

However, Zinc enters the cell through ion-channels and Zinc ionophores facilitate Zinc transport inside the cell.

Quercetin, a dietary flavonoid, has antioxidant and anti-viral properties and acts as a Zinc ionophore aiding in transporting  Zinc through the plasma membrane which is effective in stopping viral RNA replication (Dabbagh-Bazarbachi H et al, J Agric Food Chem. 2014).

Quercetin Rich Foods include:

  • Onions
  • Apples
  • Berries
  • Peppers
  • Grapes
  • Tea

These Quercetin rich foods may have anti-viral properties and can help the body prepare to fight against coronavirus.

4. EGCG (eg : Green Tea)

Epigallocatechin-3-O-gallate (EGCG),a major ingredient of green tea also has antioxidant and anti-viral properties and acts as a Zinc ionophore (Dabbagh-Bazarbachi H et al, J Agric Food Chem. 2014). Consuming Green tea as a food ingredient may hence be beneficial in fighting viral infections.

5. Vitamin C Rich Foods (eg : Citrus Fruits, Beetroot, Peppers etc)

Vitamin C is a strong antioxidant and aids in supporting a strong and effective immune system. It is one of the biggest immunity boosters of all. Regular intake of Vitamin C can reduce the duration of cold (Hemilä H et al, Nutrients. 2017). 

Vitamin C rich foods include:

  • Citrus fruits (such as oranges, lemons, grapefruits and limes)
  • Beetroot
  • Papaya
  • Red pepper
  • Green pepper
  • Yellow peppers
  • Sweet potato
  • Kale
  • Strawberries
  • Broccoli
  • Mustard Spinach

Deficiency of Vitamin C can lead to increased susceptibility to infections.Hence, include Vitamin C supplements and Vitamin C rich foods in your diet. 

6. Curcumin (Turmeric)

Curcumin from Turmeric is an excellent anti-septic and along with black pepper, it is absorbed well and helps in boosting our immune system. It has anti-inflammatory, immunomodulatory and anti-cancer effects as well (Hewlings SJ et al, Foods. 2017). It is also one of the supplements that is being used to improve specific cancer treatment outcomes in certain cancer types by including them as part of the cancer patients’ diet. Taking turmeric along with milk may also help, if you have sore throat associated with flu and other viral infections.

7. Vitamin D Rich Foods

Deficiency of Vitamin D is associated with an increased risk of viral acute respiratory infection (Greiller CL et al, Nutrients. 2015). Different studies also indicate that Vitamin D supplementation may protect against overall acute respiratory tract infections (Mariangela Rondanelli et al, Evid Based Complement Alternat Med. 2018). Vitamin D supplements and Vitamin D rich foods intake as part of our diet may be beneficial and may be added to the anti-viral food list to consider, while preparing the body to fight against coronavirus.

Vitamin D rich foods include:

  • Fish
  • Mushrooms
  • Egg Yolks
  • Cheese

While these anti-viral foods and supplements are not expected to cure COVID-19, taking these as part of our healthy diet (nutrition) may help us boost our immune system and prepare our body to fight against the coronavirus.
