Smile and say "Cheese"! That's not me talking, it's your lungs!  Coronavirus attacks the respiratory system with the worst cases being put on ventilators.
I'm not here to say this new information means help in fighting COVID-19 but a new study from the UK found that people who had low levels of vitamins A, E, and D had more respiratory issues, even when other factors like weight and smoking were taken into account.
And here's the thing, you don't have to go the the pharmacy when a stop at the grocery will do.
Vitamin A is found in whole milk, cheese, and dark green leafy vegetables.  You'll find Vitamin E in vegetable oils, nuts, and seeds—both of these vitamins are believed to boost the immune system.
Medline plus reports , "You can get vitamin D in three ways: through your skin, from your diet, and from supplements. Your body forms vitamin D naturally after exposure to sunlight. However, too much sun exposure can lead to skin aging and skin cancer. So many people try to get their vitamin D from other sources. Vitamin D-rich foods include egg yolks, saltwater fish, and liver. Some other foods, like milk and cereal, often have added vitamin D."
The Daily Mail reports, "People with healthy levels of these three vitamins are thought to be better able to ward off lung conditions such as asthma, emphysema, and even the common cold."
