This COVID-19 pandemic has made people realize the importance of a healthy lifestyle and the need to boost the immune response. A strong immune system means protection from every possible foreign invasion and infection. Since the cases are at its peak these days, people should now reconsider their diet plan and include vitamin D and vitamin A to protect themselves from the virus, research says.

With the new research, India has taken one step forward to protect its people. The Food Safety and Standards Authority of India (FSSAI) aims to add layers of protection by including vitamin D and vitamin A in all their edible oils.

Both these vitamins are essential components of health and the immune system. In addition, deficiency in any of them can cause you to face various health complications. According to recent research, stable levels of vitamin D in the body can lessen the need for artificial oxygen in COVID-19 infected patients.

Understanding Fortification Process

Food fortification is enriching the food with micronutrients that are not naturally found in them. This process can be costly but beneficial at the same time, considering that it can help deal with different health concerns.

Some examples of the fortification process include iodine in salt to deal with goiter and vitamin D in milk to strengthen bones.
