Tips to Improve Your Body’s Immune System

Toughen up with almonds

To help ward off viral infections, make 3 ounces of almonds part of your daily diet—but keep the skins on. Italian researchers studying the herpes viruses that cause cold sores have found that a chemical in almond skins improves the ability of white blood cells to detect viruses; they found that the chemical could also help prevent a virus from spreading throughout the body. Add a handful of almonds to your morning cereal or oatmeal to boost your immune system and keep viruses at bay.
