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.
GI numbers are available only for several hundred commonly eaten foods, such as carrots, watermelon, and potatoes, but not for mixed foods, like casseroles and vegetable soup. GI does not consider the portion of food, but glycemic load (GL) does. The GL takes the glycemic index of a food and considers its common serving sizes to give a more practical indicator of the effect of that food on blood glucose. Many of the foods with a low glycemic index are healthy foods. Consider eating more whole grain breads and cereals, legumes, and fruits and vegetables.
