AlgDesign om vattenlösliga fibrer

Enligt Nationalencyklopedin har alger med vattenlösliga fibrer ”gynnsam effekt på blodsockerhalten och insulinsvaret efter en måltid och kan även sänka blodets kolesterolmängd”.

De kan alltså hindra att man får diabetes och sjukdomar i hjärtat och blodomloppet.

Innehållet av fett är lågt i alger och det fett som finns är omättade fettsyror, vilket anses ha en förebyggande verkan på hjärt- och kärlsjukdomar.

Vid försök på råttor som fick en diet av 5% torkade ätliga alger, sänktes deras kolesterolhalt i blodet.

Seaweed, alginate and heavy metals

One possible application of alginate/seaweed is for the inhibition of absorption of lead, the concentration of which is steadily increasing in our environment  ex. anti-knock agents in gasoline, from where it contaminates food products and finally raises blood lead-level. These findings can be extended to barium, cadmium and zinc, and alginates/seaweed are recommended as a preventive measure in areas such as the vicinity of mines and chemcial plants, where a high degree of pollution from metals exists. If we include the populations of all industrial areas and all polluted large cities in the world into the part of mankind which  could need a chemical protection from heavy metals, there are still supplies enough. A good three quarter of the world´s unexploited seaweed/alginate resources are made up by an estimated 26 million tons of brown algae/seaweed, all in cold waters. This figure does not refer to the standing crop but to the potential of harvestable seaweed available with reasonably increased efforts. Largest in bulk may be the supplies of kelp and rock-weed belonging to the genera Laminaria, Asco and Fucus.

Seaweed, alginates and strontium

If the body uptake is not prevented by alginates/seaweeds the strontium is absorbed by the blood and deposited in the skeleton, where it may cause bone tumours or leukaemia. Alginates/seaweeds can even be used to reduce strontium already deposited in the bone. It is supposed that some of this is released slowly, re-secreted, possibly through the bile, and then bound in the intestines by alginates/seaweeds and excreted, if alginate treatment is given; otherwise it is re-absorbed by the blood. Thus alginate/seaweed can serve both as a preventive and a therapeutic measure. The phycocolloids of red algae do not possess this property but algaes as laminaria, asco and fucus has this property. In addition to a high level of guluronate units fo the alginate a certain chain length ( 150 units polyguluronate) is essential for the highest biological activity. Suitable combinations could be looked for within the natural resources, or obtained through partial hydrolysis of  the alginates/seaweeds.

Seaweed. Metal binding and radiation protection properties of Alginate.

Seaweed and Marine algae have a high ability to concentrate metal ions from sea water. For this reason they are an outstanding source for trace elements, and health-giving as food. Among the ions concentrated are also radionuclides with low concentration factors of 10 to 100 thus normally only at harmless levels. It has been suggested that hazardous or inappropriate local contamination of sea areas could be detected by assaying radioactivity in seaweed/marine algae. In brown seaweed/algae the ability to take up radionuclides is based on the ability of alginic acid to form insoluble complexes with strontium. In case when dairy products, cereals, fish or meat may be contaminated, the body upptake can be prevented by addition of alginate to food. Alginate samples in which the ratio mannuronic acid/guluronic acid is less than 1.0 are remarkable active, inhibition reaches 89%. The strontium isotope is bound to the alginate and passes through the intestines without being absorbed into the body. Highest inhibition values were found in Laminari, Ascophyllum and Fucus.
