Almonds
Sadly, vitamin E is not that popular when it comes to fighting off colds. Although most of us know what vitamin C can do to our immune system; when it comes to vitamin E, we tend to leave the question blank.
Note that vitamin E is also essential to keeping a healthy immune system. Most nuts are good sources of this vitamin, but almonds, in particular, have the highest amount. The daily recommendation for adults is approximately 15 mg per day.
Imagine that a handful of almonds can provide the entire recommended daily amount.
