Orange fruits and vegetables, such as carrots and sweet potatoes, are rich in beta-carotene. When we eat those foods, our bodies convert the beta-carotene into Vitamin A, which is essential for maintaining a strong immune system.
Vitamin A is especially important for areas that are affected when we get a cold: It keeps the mucous membranes that line our nose and throat – one of the body’s first lines of defense – healthy and functioning properly.
The surface of our eyes have a similar membrane which needs Vitamin A. Our retina inside the eyes also needs Vitamin A to function properly.
So, eat those orange carrots and sweet potatoes to help avoid colds this winter and to keep your vision bright!
