Brown Algae (Sargassum Subrepandum) from Egypt Exhibited High Nutritional Composition and Bioactive Constituent's Content: A Biological Application on Obesity and its Complications in Experimental Rats

Obesity is a medical problem that increases the risk of other diseases and health problems known as complications of obesity. In view of the side effects that resulted from the use of drug therapy and surgical interventions in the treatment of obesity, some of which posed a threat to health, which called for the search for safe and alternative alternative/natural methods. Therefore, the current study was conducted with the aim of exploring the effect of dietary intervention using marine algae (Sargassum subrepandum) on obesity and its complications in experimental rats. Sargassum subrepandum powder (SSP) showed a high nutritional composition through its high of essential nutrients (carbohydrates, fiber, protein and ash), minerals (K, Na, Ca, Zn, Fe, Cu and Mn) and vitamins (A, C, B2, B3, B9, E). It also contains many of the following bioactive constituents: polyphenols, flavonoids, carotenoids, tannins, terpenoids, triterpenoids, polysaccharides, anthocyanin’s and kaempherol, which resulted in high antioxidant activity. On the other side, biological experiment indicated that rats of the model obese group recorded 335.01 g i.e. increased by the rate of 115.60% when compared to the base line. Intervention with SSP by 1.5, 3.0, 4.5 and 6.0% lead to significant (p?0.05) decreasing on body weight of the model obese rats which recorded 108.06, 94.46, 77.28 and 73.18 %, respectively when compared to the base line. Also, SSP was effective in protecting against obese complications including inhibit liver disorders through liver serum enzymes-lowering activity, improvement of the serum antioxidant status (increase the glutathione fractions and decrease the formation of malonaldehyde and reactive oxygen species). The histological examinations of the heart and adipose tissue confirmed these results. In conclusion, we recommended SSP by a concentration up to 6% to be included in daily diets, drinks and food supplementation of normal and obese people.How to Cite: Yousif A. Elhassaneen, Hadeer M.
