In winter, many women experience a phenomenon of being particularly sensitive to cold. This sensitivity is related to the body's insufficient intake of certain minerals. For instance, an iron deficiency in the blood often manifests as reduced heat production and low body temperature. The level of calcium in the body can directly affect the contractility and excitability of the heart muscle, blood vessels, and muscles. Therefore, supplementing with foods rich in iron and calcium can enhance the body's ability to withstand cold. Every 100 grams of kelp contains up to 1177 mg of calcium and 150 mg of iron, making kelp a treasure trove for human calcium and iron intake. From a Traditional Chinese Medicine perspective, seawater is considered yin, cold, and cool, and kelp, growing in such an environment, possesses an extremely strong cold-resistant nature. Kelp has a salty flavor, and long-term consumption can also warm and tonify kidney qi. Thus, consuming kelp can increase the body's resistance to cold.
Women who are sensitive to cold should regularly consume kelp, as the iodine in kelp can stimulate the pituitary gland, correct female endocrine imbalances, and reduce the occurrence of hyperplasia of the mammary glands. Iodine is an essential element for the synthesis of thyroid hormones. Some women's sensitivity to cold may be due to low thyroid activity or concurrent iron-deficiency anemia. Kelp is rich in iron, which can correct anemia. Therefore, women who are sensitive to cold can improve their symptoms by eating more kelp.
Kelp is considered cold in nature, so it should be avoided by individuals with a weak or cold spleen and stomach. Patients with hyperthyroidism should not eat kelp. People with gastrointestinal diseases, especially gastric and duodenal ulcers, should also avoid kelp. Individuals with severe acne or allergies should not eat kelp either. Pregnant and breastfeeding women should not consume excessive amounts of kelp, as the iodine in kelp can enter the fetus's or infant's body through the bloodstream, causing thyroid dysfunction.
