Why Proper Nutrition is Vital for Fighting Infection

Researchers have discovered that an amino acid, called arginine, is required to let your body know that it's being attacked by an infection. This may be one reason why proper nutrition can have such a strong effect on your immune response.

It may also be the mechanism involved in chronic inflammation -- if you have too much arginine, it may cause your body to be in a constant state of thinking it is being attacked.

Science Daily reports:

“In a healthy person, macrophages are the first cells to arrive at the site of infection ... [It was] known that arginine is essential for the function of macrophages but until now no one realized that arginine has a much bigger role.”
