Yes, people with tuberculosis (TB) can eat salt, and in fact, it's often recommended in controlled amounts.
The historical reference provided indicates that completely eliminating sodium chloride (salt) from the diet of TB patients can lead to digestive issues and weaken their resistance to the bacteria. Consequently, the referenced dietary treatment included two grams of salt daily for patients.
Therefore, while a very low-sodium diet might have been considered at some points in history, current understanding generally advocates for a balanced approach. Complete sodium restriction isn't beneficial and can be detrimental. Maintaining adequate electrolyte balance is crucial for overall health, including when battling an infection like tuberculosis.
It's important to consult with a doctor or registered dietitian for personalized dietary recommendations while undergoing TB treatment. Individual needs may vary based on factors such as kidney function, other medical conditions, and medications. They can provide tailored guidance on salt intake to ensure optimal health during recovery.
