Taking zinc counteract a cold?

Q: Dear Dr. Mao,
Is it true that taking zinc can help you counteract a cold?

A: Zinc is a famous natural treatment for colds. In cases of zinc deficiency, the immune system does not function properly. Because zinc is commonly deficient in the diet, nutritional zinc supplements may certainly be useful for those who get sick easily.
