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 tool called the glycemic index (GI) can help. It rates carbohydrate-containing foods by how much they boost blood sugar (blood glucose). As someone with diabetes, I use the glycemic index as one strategy to keep my blood sugar under control.
