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.
The mechanism by which the two main pathways are accessed depends on the Glycemic Index (GI) and Glycemic Load (GL) of the edible item. If the consumed item has a High GI and GL, it will primarily take Pathway number one (1). If the food has a Low GI and GL, it will primarily take Pathway number two (2).
