Bacteria and viruses depend upon our biochemistry to survive which explains why some escape illness whilst others suffer.
Bacterial infections (like staphylococcus and streptococcus) proliferate within an acid environment, while viruses (like flus and the common cold) proliferate in an alkaline environment.
I've posted many long articles discussing how the changing seasons are responsible for over Alkalizing us and making us susceptable to the Flu virus but all most people seem to want in a list of what to eat and what to avoid.
ACID (Eat like this to get rid of flu) Avoid for a bacterial infection such as a sore throat.
tomatoes
nuts
seeds
cheese (may cause mucus build up)
mayonnaise
WHOLE GRAINS
fried eggs
cherries
cranberries
vinegar
FATS, OILS
PROTEINS
ALKALINE (Eat these to help a sore throat) Avoid when you have the flu.
alcohol (remember this will lower the immune systems ability to function so won't help long term)
coffee
sugar (will also lower immune function)
chocolate
salt
refined grains
FRUITS
DRIED BEANS
OTHER DAIRY
VEGETABLES
POACHED EGGS
Be well
