100g kelp, the content of protein is 8.2g, and the carbohydrate is 56.2g, which exceeds that of most land and water vegetables. The contents of calcium and iron are extremely rich, reaching 1 177 mg and 150 mg respectively. The iodine content is particularly significant, reaching 240 micrograms; The average adult 150 micrograms per day can meet the needs; In addition, B 10.09 kelp also contains 0.75mg of carrot, 0.09 mg of vitamin B/kloc-0, 0.6 μ g of nicotinic acid/kloc-0, 2 16mg of phosphorus and 22μ g of cobalt. Kelp contains almost no fat, but a lot of cellulose, alginate and so on.
Its main pharmacological effects are as follows:
(1) Adjust the blood pH value. Regular consumption of kelp can effectively regulate the pH of blood. Because kelp is an alkaline food rich in calcium, the calcium contained in 3 ~ 5g kelp is equivalent to that contained in 160g spinach or 250g citrus.
(2) Anti-cancer effect. The test results show that the blood of cancer patients is mostly acidic. Kelp is an alkaline food rich in calcium. Can reduce the acidity in the 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. The incidence of breast cancer in Japanese women is very low, which is considered to be related to eating more kelp.
(3) prevention of leukemia. Algin in kelp can prevent leukemia.
(4) hypotensive effect. Alginic acid in kelp has the effect of lowering 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. Because kelp contains high iodine, it can prevent goiter.
(7) the role of intelligence. Iodine, known as an intellectual element, is a component of thyroxine, which has a great influence on the growth and development of the brain and bones. The elderly will also lack iodine because of monotonous food composition and decreased digestive function. Iodine deficiency will aggravate mental decline, so the elderly should pay attention to iodine supplementation. Because kelp is rich in iodine, it has educational function.
(8) Other functions. Because kelp is rich in mannitol, it has certain curative effect on acute renal failure, brain edema and acute glaucoma.
To sum up, kelp is really a longevity dish, because it has high nutritional value and dietotherapy value. In addition to kelp, seaweed foods such as laver and Undaria pinnatifida also have ingredients and functions similar to kelp. Therefore, kelp, seaweed, Undaria pinnatifida and other seaweed foods must be eaten, not less.
