Boost your immunity against COVID-19

Now more than ever, it is important for your immune system to stay in tiptop shape with the Covid-19 pandemic threatening a resurgence in winter across the world. One of the best ways to stay healthy is by maintaining a nutritious diet. Here are some of the foods that can help boost your immune system.

Vitamin A

This vitamin assists with the health of your intestines and respiratory system. Vitamin A-rich foods include carrots, sweet potato, spinach, broccoli and red bell peppers.

Vitamin C

Vitamin C helps stimulate the formation of antibodies. This particular vitamin is a crucial participant in the army of immunity. It helps prevent the common cold. Citrus fruits, strawberries, red bell pepper and kiwi are all rich in vitamin C.

Vitamin D

Vitamin D supplements have a mild protective effect against respiratory tract infections. Most people are deficient in vitaminD, so it is best to consult with a doctor about taking a vitamin D supplement to boost immune response.

Vitamin E

This nutrient promotes the neutralisation of free radicals by working as an antioxidant. Foods full of vitamin E include vegetable oils, nuts, seeds and avocado.


There are many zinc-dependent enzymes in our body and deficiency has been linked with immune dysfunction.Zinc deficiency often makes one more susceptible to flu, cold and other viral infections. Zinc-rich foods include beans, seeds, nuts, meat, poultry and seafood.


Specific amino acids found in protein are essential for T-cell function, which are cells that protect the body against pathogens. Meats, poultry, seafood, eggs, beans, nuts and seeds all have lots of protein.

These nutrients have been shown to help your immune system work most efficiently and effectively, but too much of a good thing can be harmful. Eat these nutrients in moderation and stay healthy. As always with preventing the spread of illness, wash your hands frequently and maintain social distancing.
