Deficiencies of certain nutrients can cause our immune systems to function poorly. Be sure to include healthy protein sources, colorful vegetables and fruits, fermented foods, nuts, seeds, and water in your diet. Also be sure to wash your hands frequently and get plenty of sleep. Schedule an appointment to determine if you have any specific nutritional weaknesses.
A correction to the article: do NOT include wheat or gluten in your diet as gluten can lead to leaky gut and suppress your immune system!
