Introduction
Under normal circumstances, it is not recommended to eat pineapple after I-131 treatment, as it may affect the treatment outcome. After undergoing I-131 therapy, patients should avoid consuming foods high in iodine, such as kelp, nori, and sea fish. It is advisable to eat more fresh vegetables and maintain proper hydration, which can help alleviate symptoms such as dry mouth and skin dryness.
Generally, it is not recommended to eat pineapple after I-131 treatment, as it may affect the treatment's effectiveness. The detailed explanation is as follows:
I-131 is a radioactive isotope of the element iodine, primarily used in the treatment of diseases such as hyperthyroidism and thyroid cancer. This treatment works by the uptake of radioactive iodine, which destroys thyroid tissue to reduce thyroid hormone secretion or eliminate thyroid cancer cells. Pineapple contains a certain amount of iodine; although its iodine content is not as high as that of seaweed, kelp, and other seafood products, patients need to control their iodine intake after I-131 treatment. Consuming pineapple at this time might affect the accumulation of I-131 in the thyroid gland, thus influencing the treatment outcome.
After I-131 treatment, patients should avoid foods high in iodine, such as kelp, seaweed, and sea fish. It is advisable to eat more fresh vegetables and maintain proper hydration, which helps alleviate symptoms such as dry mouth and dry skin.
