Patients with tuberculosis can normally eat onions during their medication period. It is beneficial to eat more vegetables and fruits to provide the body with ample vitamins and fiber. In addition to eating onions, there should also be a proper intake of high-quality proteins, such as chicken, duck, fish, lean meats, eggs, and soy products, as well as foods rich in carbohydrates and calories. Timely and standard anti-tuberculosis treatment is crucial; patients must take their medication regularly. Most patients can fully recover if the medication is taken on schedule. Irregular and untimely medication can lead to poor treatment outcomes.
