100g kelp contains 82g of protein and 5629g of carbohydrate, which is beyond the reach of most land and water vegetables. The contents of calcium and iron are extremely rich, reaching 1 177 mg and 150 mg respectively. The content of iodine is particularly significant, reaching 240μg, while the average adult's daily 150μg can meet the needs. In addition, B 1009 kelp also contains 0.75mg of carotene, 0.009 mg of vitamin B/KLOC-0, 0.6 μ g of nicotinic acid16 mg of phosphorus and 22μg of cobalt. Kelp contains almost no fat, but a lot of cellulose, alginate and so on.
Its main pharmacological effects are as follows: ① Adjusting the pH of blood: Regular consumption of kelp can effectively adjust the pH of blood. Because kelp is an alkaline food rich in calcium, the calcium contained in 3 g ~ 5 g kelp is equivalent to that contained in 160 g spinach or 250 g citrus.
② Anti-cancer effect: The blood of cancer patients is mostly acidic. Kelp is an alkaline food rich in calcium, which can reduce the acidity in blood, so it has anti-cancer effect; Kelp has anticancer effect because it can selectively filter out carcinogens such as strontium and cadmium. Also, because the fiber contained in kelp is not easy to be digested, after eating, the intestinal peristalsis increases and the stool is smooth, which helps to excrete toxic substances in the body.
③ Prevention of leukemia: Algin in kelp can prevent leukemia.
④ Hypotensive effect: Alginic acid in kelp can reduce blood pressure.
⑤ Hypolipidemic effect: Starch sulfate in kelp is a kind of polysaccharide, which can reduce cholesterol, so it can prevent arteriosclerosis.
⑥ Prevention and treatment of goiter: Due to the high iodine content in kelp, goiter can be prevented.
⑦ Intellectual function: Iodine is called an intellectual element, which is a component of thyroxine and has a great influence on the growth and development of the brain and bones. Because the food composition of the elderly is monotonous, the digestive function declines, and iodine deficiency will also aggravate the mental decline, so the elderly should pay attention to iodine supplementation. Because kelp is rich in iodine, it has educational function.
⑧ Other effects: Kelp is rich in mannitol, which has a certain effect on brain edema and acute glaucoma.
