Common causes of viral pneumonia include Influenza A or B (flu), respiratory syncytial virus (RSV), parainfluenza, and adenovirus. Worldwide, viral pneumonia is the leading cause of death among children younger than 5 years old.
Fat alone or in combination with protein does not raise blood glucose, so foods such as butter, margarine, oil, and meat do not have a glycemic index value. When fat is combined with carbohydrate, it tends to lower the glycemic index value of the food, since fat slows digestion.
A GI of 70 or more is high, a GI of 56 to 69 inclusive is medium, and a GI of 55 or less is low. The glycemic load (GL) is a relatively new way to assess the impact of carbohydrate consumption that takes the glycemic index into account, but gives a fuller picture than does glycemic index alone.
