ORTIZ-ROJAS, Viviana J; BERNUY-OSORIO, Nataly D; ZEA-MENDOZA, Otto A  and  VILCHEZ-PERALES, Carlos. Effect of Solanum tuberosum peel or pulp on organ weight and hepatic oxidative stress in obese rats. Rev. perú. med. exp. salud publica [online]. 2019, vol.36, n.4, pp.681-686. ISSN 1726-4634.

This study aimed to determine the effect of the consumption of peel flour or pulp flour from two varieties of Solanum tuberosum (Yungay potato and Canchán potato) on the accumulation of adipose tissue, organ weight, and oxidative stress in the liver of rats. We carried out an experimental study in 24 obese Holtzman rats, divided into four groups and subjected to diets containing 10% flour from both varieties of potato. The groups were T1: Yungay peel; T2: Yungay pulp; T3: Canchán peel; and T4: Canchán pulp. When the study was completed, all the animals were slaughtered to record the weights of organs and adipose tissue and to extract samples to determine the enzyme activity of superoxide dismutase and catalase in the liver. The group of obese rats that consumed the pulp of the Yungay variety had less oxidative stress in the liver. Also, regardless of the tuber part consumed, this variety reduced the weight of the kidneys.
