Scientists have discovered that kelp is a treasure trove for human intake of calcium, iron, and iodine. In every 100 grams of kelp, there is a high content of 1177 milligrams of calcium, 150 milligrams of iron, and 240 milligrams of iodine, making kelp crucial for the health of the elderly.
The sodium alginate in kelp has the function of preventing osteomalacia and reducing blood pressure. Kelp starch sulfates are polysaccharide substances that have the ability to lower blood lipids. Kelp can also reduce the absorption of radioactive elements in the intestines. All of these factors contribute to kelp's reputation as the "vegetable of longevity".
