How many people have you heard coughing and sneezing around you lately? Cold and flu season is already upon us! I am a fan of frequent hand washing as a means of prevention and always keep some sanitizer nearby, but you can do more. You can also prime your immune system to be a fighting machine. Start by eating a well-balanced diet, full of fruits and veggies, to nourish your immune system and try these other techniques to fight the good fight against the germs of the season.
