Marine algae like the brown, red and green seaweeds contain specific bio-active components that have valuable food sources full of healthy attributes.
Recent and multiple studies show that eating algae can have enormous and strong impact on health due to sulfated polysaccharides. Many metabolites have been isolated from marine biomasses that have exhibited excellent biological activities, especially as anticancer agents. They also exhibit various biological activities such as anticoagulant, antiviral and anti-oxidative activities with potential health benefits.
- Sargassum polycystum, brown seaweed reduced dyslipidaemia in type 2 diabetic rats. S. polycystum is a potential insulin sensitizer, for a complementary therapy in the management of type 2 diabetes. It can help reduce degenerative accumulation of lipid-containing plaques on the innermost layer of the wall of an artery and calcium in the arterial lumen. It has also shown to lessen weight.
Fucoidans and alginates are complex polysaccharides extracted from brown seaweeds.
- Fucoidans inhibits proliferation and induces apoptosis of several tumor cells of human breast cancer MCF-7.
- Alginic acid shows to decrease allergies like atopic dermatitis
- Agar and carrageenan are polysaccharides extracted from marine red macroalgae
- They are polysaccharides like glucose, galactose, xylose, mannose and arabinose in green algae.
