With coronavirus keeping many people from being active, keeping your immune system healthy is critical. There are a number of things you can do such as getting enough exercise, not smoking, staying hydrated, having quality sleep time and eating a healthy diet. Sticking to a Mediterranean diet is a good way of keeping your good health, and it’s delicious. A study published in the journal Frontiers of Physiology found that healthy people aged 65-79 who ate a Mediterranean diet and took 10 micrograms of Vitamin D daily for a year were able to help offset age-related declines in immunity. The Mediterranean diet involves eating a lot of vegetables, fruit, nuts, whole grains and one ounce of food daily. Stay away from red meats and instead eat salmon and other fish, with modest portions of egg. Olive oil is the fat of choice, and a glass or two of red wine each night tops of the meal.
