• Resumen

  • Purple sweet potato (PSP) is widely grown in Asia and considered as a healthy vegetable. The objective of the current study was to determine the anti‐obesity effect of the PSP on high fat diet induced obese C57BL/6J mice. The mice were administrated with high fat diet supplemented with the sweet potato (SP) or PSP at the concentration of 15% and 30% for 12 wk, respectively. The results showed that the supplementation of SP or PSP at 30% significantly ameliorated high fat diet induced obesity and its associated risk factors, including reduction of body weight and fat accumulation, improvement of lipid profile and modulation of energy expenditure. Moreover, PSP also posed beneficial effect on the liver and kidney functions. These results indicate that PSP and SP have anti‐obesity effect and are effective to reduce the metabolic risk. Purple sweet potato is rich in fiber and anthocyanin and other ingredients. In this article, the preliminary study shows that purple potato can inhibit the weight gain in mice, which will bring to obese patients a way to lose weight. And at the same time, manufacturers can produce a series of products by using purple sweet potato to expand business opportunities.
