Conclusions
Maca supplementation improved the digestibility of nutrients and expressions of nutrient transporters in the small intestine of the rats. These results indicate the positive communication between maca consumption and nutrient absorption in the small intestines of the animals.
Results
A total of 28 Sprague-Dawley rats (8-week-old) were divided into four groups: (i) control, (ii) Lepidium m., (iii) high-fat diet (HFD), and (iv) HFD+Lepidium m. Maca was given to the rats as a powdered combination of the plant roots with a daily dose of 40 mg per kg BW. Maca administration significantly increased the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), and ether extract (EE), and some nutrient transporter (Pept1/2, Fatp1, Glut1/2, and Sglt1)-expressions compared with non-treated control and HFD groups in the jejunum and ileum tissues (p < .0001). Conclusions: Maca supplementation improved the digestibility of nutrients and expressions of nutrient transporters in the small intestine of the rats. These results indicate the positive communication between maca consumption and nutrient absorption in the small intestines of the animals.
