Negative Effect of Camu-Camu (Myrciaria dubia) Despite High Vitamin C Content on Iron Bioavailability, Using a Caco-2 Cell Model
Is Version Of
It is well known that vitamin C is an important enhancer of nonheme iron bioavailability due to its high reducing capacity. Camu-camu, a fruit that grows in the jungle of Peru, contains high amount of vitamin C (2,780 mg per 100 g). In this study, we investigated the effect of camu-camu on nonheme iron bioavailability from two different meals (rice with lentils and wheat flour porridge) using an in vitro Caco-2 cell model. These two meals were treated with three different camu-camu juice concentrations (C0 = 0 g, C1 = typical consumption, and C2 = 3X typical consumption). The results showed that camu-camu reduced rather than enhanced nonheme iron bioavailability. The inhibiting trend was significant (p
