Question

why do people consuming sea foods do not suffer from goitre

Answer 1

goitre is caused by the lack of iodine or salt. sea food is rich in both these minerals and thus people consuming sea foods such as fish and crabs do not suffer from goitre. they get the required minerals and vitamins required by their body namely iodine and salt

Answer 2

Seafood is Rich in iodine. Iodine is required for the proper functioning of the thyroid gland which secretes the hormone thyroxine.Hyposecretion(under secretion) of thyroxine leads to goitre. Due to consumption of seafood,the body receives suffecient iodine and therefore people do not suffer from goitre
