A, different morphological characteristics

1, wakame: perennial large brown algae. Algae body brown, soft leathery, 1 ~ 2 meters long, 50 ~ 100 mm wide, the overall outline of the lanceolate, the center has a clear protruding main ribs, thinner on both sides.

Often forming a majority of pinnate lobes, the margins of the lobes are notched, sometimes undivided, densely covered with mucous glands. The rhizome-fixing apparatus is fibrous and consists of andiformly divergent pseudoroots, which have sucking disks at the end.

2, kelp seedling: the algal body is a long flat leaf-like body, brownish green, there are two longitudinal grooves running through the middle of the blade, forming the middle band, generally 1.5-3m long, 15-25cm wide, the longest up to 6m, up to 50cm wide.

Second, the nutritional composition is different

1, wakame: wakame is a natural treasure trove of trace elements and minerals, containing More than a dozen essential amino acids, calcium, iodine, zinc, selenium, folic acid and vitamins A, B, C and other minerals. Wakame contains calcium is the "king of calcium" milk 10 times, zinc is "zinc can" beef 3 times.

2, kelp seedlings: kelp is rich in kelp polysaccharides, so far has been found to have three kinds of polysaccharides: fucoidan, fucoidan, fucoidan starch. It also contains acidic polysaccharides, fucoidan galactopolysaccharide sulfate, macroalginin, galacturonic acid, kombuchin, taurine, bifidus factor and many other active ingredients.

Three, the efficacy of different

1, wakame: wakame in the insoluble plant fiber insoluble in water, will not be easily digested and absorbed, it can play a role in the human intestinal tract to increase the amount of fecal matter, soft fecal matter, but also play a role in stimulating the intestinal wall, to promote peristalsis, which reduces the fecal matter stays in the body of time, and indirectly reduces the prevalence of colorectal cancer. The fact is that this is a good way to reduce the incidence of colorectal cancer.

2, kelp seedlings: kelp can prevent the absorption of the radioactive element strontium. Radioactive strontium into the human body is very harmful to the human body, can radiate rays in the body, causing damage to the bone marrow, and damage to its hematopoietic function, affecting the growth of bone marrow, and induced bone cancer and leukemia.

Sodium alginate in kelp not only prevents strontium from being absorbed by the digestive tract, but also has a discharging effect on the old radioactive strontium in the organism. In addition, sodium fucoidan has a lead discharge effect in the body. Lead into the body will cause serious harm to the nervous system and hematopoietic system, and often eat seaweed will play a role in the discharge of lead.
