Nuts
You already read that almonds are a great ingredient to help you fight off the common cold and flu, but so are other nuts. One reason is that most nuts contain the right amount of vitamin E, which fights off diseases by decreasing inflammation.
Researchers published a study they concluded in the Journal of the American College of Nutrition that looked at how nuts help boost your immunity. The study found that people who ate about 50 mg of vitamin E through nuts reduced their risk of catching a cold by 28 percent in people 65 years old and above who were daily smokers.
