RODRIGUEZ, Nidia María; CIOCCIA, Anna María; GUTIERREZ, Marlén  e  HEVIA, Patricio. Fiber and antioxidant capacity of edible algae in vitamin E sufficient and deficient rats. Acta bioquím. clín. latinoam. [online]. 2018, vol.52, n.2, pp.213-226. ISSN 0325-2957.

In western countries, edible seaweed consumption has markedly increased in recent years. Accordingly, in this study the antioxidant capacity and fiber value of Nori and Wakame algae were evaluated in growing rats fed with sufficient of deficient vitamin E. There were 3 groups of rats: 1. Control, 2. Nori and 3. Wakame with vitamin E and 3 similar groups without vitamin E. The diet with Nori and sufficient vitamin E caused a reduction in growth and Nori and Wakame were associated with liver vitamin E accumulation, plasma vitamin E reduction and an increase in TBARS in liver and plasma. In contrast, when the same diets were offered without vitamin E, the Nori fed rats recovered their growing capacity, they maintained a higher vitamin E reserve than the control or Wakame fed rats, and the consumption of both algae was associated with lower plasma TBARS than vitamin E deficient rats, indicating that these algae are best accepted when offered without vitamin E. In addition, both algae improved the excretory capacity of the intestine without affecting its absorption function.
