Marine polysaccharides and oligosaccharides that encompass their anticancer, anti-inflammatory, antibacterial, antiviral, antioxidant, antidiabetes mellitus and anticoagulant properties. Seaweed has been used in Traditional Chinese Medicine for more than 2,000 years. The Shen Nung, a centuries-old medical treatise of the Yellow Emperor, includes treatment with seaweed, but also the use of kombu and hiziki to reduce edema or fluid retention, lower respiratory tract infections (especially tuberculosis) and all types of fibroids, nodules and tumors. Nori seaweed was used for the same ailments and, in addition, against urinary tract infections and upper respiratory tract infections.

In addition to their richness in minerals, algae contain large amounts of fiber and are grouped under the common name of polysaccharides or mucopolysaccharides and constitute a proportion of 25 to 40 percent of algae. The difference with the polysaccharides of plants and mushrooms is that the units of the monosaccharide chains are not glucose but galactose or mannose. In addition, they are almost always sulfated, which gives them different properties.

1) Alginates or alginic acid: interesting in weight loss diets because it is satiating, hypolipidemic, since it reduces lipid levels in the blood, and hypoglycemic, since it also reduces blood glucose levels.

The most interesting therapeutic property is its chelating capacity or property of absorbing toxins and, especially, heavy metals, and preventing their passage into the bloodstream, as they are encapsulated by polysaccharides in the intestines and are then expelled with the feces. Apart from these properties, alginates are heart-healthy, due to their hypotensive effect and lowering blood cholesterol.

2) Fucoidin: Japanese researchers differentiate two types of fucoidin: fucoidin F and fucoidin U. The former has been shown to induce apoptosis (death) of lymphoma cancer cells. Fucoidin also enhances the antitumor action of NK cells of the immune system. Fucoidins have been shown to be antibacterial, antiviral, antioxidant, antithrombotic, antiangiogenic, anti-inflammatory and hypolipidemic, regulation of intestinal flora with impact on bone metabolism----

3) β-glucan, is a storage polysaccharide derived from brown algae. It has been recognized for its possible pharmacological effects, which include antioxidant, anticancer, and immunomodulatory properties.---

4) Carrageenan: has a unique variety of properties, encompassing antiviral, antibacterial, immunomodulatory, antihyperlipidemic, antioxidant and antitumor attributes. Studies carried out by the National Cancer Institute of the USA indicate that carrageenans have antibiotic properties. In addition, there is evidence that they inhibit the penetration of herpes viruses (HSV) into cells. ---

5) Fucoxanthin: Studies with laboratory animals have shown that this substance has anti-obesity properties while enhancing the synthesis of omega 3 fats (DHA). Fucoxanthin also has antitumor activity in in vitro trials and appears to be effective against breast cancer. prostate.---

I stopped eating nori after the Japanese nuclear power plant disaster. Isn't much of the Pacific Ocean now horribly contaminated from ongoing release from that accident?

Is there a way to get seaweed that hasn't been contaminated?
