As laboratories around the world continue efforts towards a COVID-19 vaccine, the best chance anyone has at surviving the virus at this point is a strong immune system. And there are many ways to do this says Assistant Professor of Emergency Medicine, Dr. Zulfikar Bux. Along with the regular intake of Vitamin C which helps to improve immune function, Dr. Baux recommends a balanced intake of Vitamin D and Zinc.

In relation to the latter, Dr. Bux said it is a mineral found throughout cells in the body. The Professor of Emergency Medicine noted that there are a number of ways zinc boosts the immune system but primarily, it activates enzymes that break down proteins in viruses and bacteria, thereby making them less able to spread. Dr.Bux said it also increases the activation of cells responsible for fighting infections and helps to reduce inflammation that can occur during viral infections. Dr. Bux said that individuals need eight to 12mg of zinc to meet daily requirements. This mineral can be found in guavas, seafood such as crabs and lobsters, beans and nuts, avocados, and ground beef.

Turning his attention to Vitamin D, the medical official said that this is an essential nutrient that plays a critical role in promoting immune response. Dr. Bux said that it has both anti-inflammatory and immune regulatory properties and is crucial for the activation of immune system defenses. It enhances the function of immune cells, including T-cells and macrophages that protect the body against pathogens such as viruses. Dr. Bux cautioned that low Vitamin D levels are associated with an increased risk of respiratory diseases such as viral and bacterial respiratory infections. He said that the daily Vitamin D requirements can be had from egg yolks, fatty fish such as tuna and mackerel, cheese, and liver.
According to Dr. Bux, Quercetin is another potent immune system booster. In this regard, the medical official pointed out that it is a natural pigment present in many fruits, vegetables, and grains that can bind to and neutralize free radicals formed from infections such as COVID-19. He noted that it has strong anti-inflammatory properties which are very handy since the COVID-19 infection triggers a massive inflammatory response in the body that worsens the illness. This flavonoid can be found in grapes, apples, black tea, tomatoes, and citrus fruits. He said that the daily intake of 500mg quercetin is sufficient to help the body.
