Try to keep non-iodized salt for a long time and eat less iodine-rich foods such as kelp/laver/seaweed to avoid the recurrence of hyperthyroidism, but seafood such as fish and shrimp can still be eaten, as long as it is not excessive.

But if there is hypothyroidism in the future (iodine 13 1 the common complication of treatment), then there is nothing urgent in the diet and you can eat anything.
