According to medical experts, the barium sulfate that forms the primary component of barium contrast is an inorganic compound with absolutely no nutritional value. This means it contains no calories and does not contribute to your daily dietary intake. The question, "Does barium contrast have calories?" is common for patients scheduled for medical imaging, but the main contrast agent itself is completely inert.

According to guidelines from various medical centers, following a high-protein, low-carbohydrate diet is crucial in the 12-24 hours leading up to a PET scan to ensure accurate results. This carefully managed nutritional intake helps stabilize blood sugar levels, preventing false readings during the procedure. Knowing what is a high protein meal before a PET scan is key to a successful test.
