^Normally good foods can be bad if you have a virus. With cold +
   flu season coming, now seems like a good reminder: If you have a
   virus or think you do:
   AVOID: Nuts, Seeds, Chocolate, Caffeine, Oats - Arginine in them
   FEEDS viruses. (makes you worse)

   EAT: Veggies, Fruit, Dairy (including yogurt and cheese), Eggs,
   chicken and beef. - Lysine in them STARVES viruses (makes you
   better).^
