Can I eat crab with Hashimoto's thyroiditis?

Patients with Hashimoto's thyroiditis can generally eat crabs, but they should pay attention to the type and amount of crab consumed. Hashimoto's thyroiditis is a chronic autoimmune disease in which the body's own thyroid tissue serves as the antigen, and patients need to limit their iodine intake. Crabs include both sea crabs and river crabs, with sea crabs containing higher levels of iodine, while river crabs contain relatively lower levels.

For patients with Hashimoto's thyroiditis who have normal thyroid function, moderate consumption of river crabs is acceptable, although excessive intake should be avoided, and changes in thyroid function should be monitored.

If patients develop hypothyroidism, their diet should be adjusted according to their thyroid function status, with moderate consumption of river crabs. They may also require medication, such as levothyroxine sodium tablets, to maintain stable thyroid function, and regular follow-up examinations are necessary.

In addition, patients with Hashimoto's thyroiditis should maintain a balanced diet, consume more foods rich in vitamins and minerals, and avoid spicy, greasy, or other irritating foods to support thyroid health.
