Dietary obesity and obesity-related diseases are among the widely occurring nutritional health problems in most of the developed nations in the Western world. Seaweed fiber in the diet helps to control weight gain in different ways. Adding considerable amoimt of seaweed to the diet enables to keep the dieter feel fuller quickly and to reduce the appetite dramatically for further eating. Moreover, most of the dietary fiber in seaweed is not taken up by the human body and provides a low caloric value to the diet. In addition, this soluble fiber forms a viscous mass in the...

In the field of pharmacology, the biologically active polysaccharides (PSs) that are derived from natural sources have attained a special place for the development of drug lead molecules. Marine macroalgae contain a significant amount of soluble PSs and have potential function as dietary fiber. Specially, brown marine algae are known to produce fimctional PSs such as alginates and fucoidans. Seaweed-derived PSs have been... 

Besides, seaweeds are considered an excellent source of dietary fiber with a high proportion of soluble to total dietary fiber (Gomez-Ordonez... 

Antioxidant. Sulfated polysaccharides not only function as dietary fiber, but they also contribute to the antioxidant activity of seaweeds. It has been demonstrated that they exhibit potential antioxidant activity in vitro and several of them derived from brown seaweeds, such as fucoidan, laminaran, and alginic acid, have been shown as potent antioxidants (Rocha De Souza et ah, 2007 Ruperez et ah, 2002 Wang et ah, 2008, 2010).

In addition to the above discussed nutrients, diverse amoimt of phenolic molecules has been identified from seaweed and is classified imder different groups of phytochemicals. Those molecules virtually do not play the roles of nutrients and proven to have different bioactive properties associated with enhancing physical fitness to refrain from diseases or to exert therapeutic effects against certain illnesses. However, the medicinal effects of such molecules are not discussed in this chapter. Non-communicable diseases such as diabetes, obesity, and cardiovascular dieses have a strong relationship with dietary habits and nutritional profiles of the food. Therefore, next few sections of this chapter address the nutrition-related several health effects of seaweed fiber, other than previously mentioned, and its contribution to enhance digestive health.
