据医学家分析:冷天多吃海带可以御寒。人之所以怕冷,是由于甲状腺激素分泌不足的原故。甲状腺激素是由人的甲状腺分泌的,它是由碘和酪氨酸为主要原料,经人体甲状腺合成的一种激素,具有产热的效应。同时,它能使人的皮肤血液循环加速,产生体热,抵御寒冷。因此,冬天怕冷的人,应该多吃些含碘丰富的食物,海产品中的海带、鱼、牡蛎等含碘都相当丰富,尤其是海带,含碘量最多。多吃海带还可以治疗高血压病,疗效十分显著。
According to medical analysis: cold days to eat kelp can keep warm. The reason why people are afraid of cold, is due to the lack of thyroid hormone secretion. Thyroid hormone is secreted by the human thyroid gland. It is a hormone synthesized from iodine and tyrosine and synthesized by the human thyroid gland. It has the effect of producing heat. At the same time, it can accelerate the blood circulation of human skin, produce body heat and resist the cold. Therefore, those who are afraid of cold in winter should eat more foods rich in iodine. Sea foods such as kelp, fish and oysters are quite rich in iodine, especially kelp, which contain the most iodine. Eat kelp can also treat hypertension, the effect is very significant.
