What dietary changes can decrease Theophylline levels?

High carb/low protein diet
Vegetarian diet
High fat/low carb diet
Low carb/high protein diet

The correct answer is: Low carb/high protein diet

The correct answer is a low carb/high protein diet because carbohydrates can increase the metabolism of theophylline, potentially leading to lower drug levels. Protein, on the other hand, may compete with theophylline for binding sites, thus reducing its absorption and increasing its elimination. Therefore, opting for a low carbohydrate and high protein diet can potentially reduce theophylline levels in the body. A high carb/low protein diet (Option A) would not decrease theophylline levels; in fact, high carb intake can increase the metabolism of theophylline. A vegetarian diet (Option B) does not specifically address the dietary components that influence theophylline levels. A high fat/low carb diet (Option C) may not directly impact theophylline metabolism or elimination in the same way that a low carb/high protein diet does.
