People are susceptible to cold due to a lack of certain minerals in their bodies.For example, the amount of calcium in the human body directly affects the contraction and excitability of the heart, blood vessels, and muscles.A deficiency of iron in the blood is a major cause of iron-deficiency anemia, which often manifests as reduced heat production and low body temperature.Therefore, supplementing with foods rich in calcium and iron can improve the body's ability to withstand cold.Scientists have discovered that

Kelpis a treasure trove of calcium and iron for humans.In 100 grams of kelp, the calcium content reaches 1177 mg, and the iron content reaches 150 mg, so kelp is important for the health of children, women, and the elderly in winter.Kelp is rich in iodine, which promotes the secretion of thyroid hormones and generates heat.There is a substance called thyroid hormone in the human thyroid, which can accelerate the oxidation of many cells in the body, increase the body's heat production, enhance the basal metabolic rate, accelerate skin and blood circulation, and resist cold.

The average adult needs about 150 micrograms of iodine, but 100 grams of kelp contains 240 mg of iodine.The thyroid gland secretes a substance called thyroid hormone, which can accelerate the oxidation of many cells in the body, increase the body's heat production, and enhance the basal metabolic rate, speeding up skin blood circulation and resisting cold.The average adult needs about 150 micrograms of the trace element iodine, while 100 grams of kelp contain 240 milligrams of iodine.
