Resumo
The objective of this study was to verify whether soluble fiber pectin interferes in growth and intestinal iron absorption in rats during iron deficiency anemia recovery. Twenty-one-day-old Wistar rats (n = 48) were fed for 2 weeks on a diet without iron in order to induce iron deficiency anemia. the anemic animals (age = 36 days) were divided into two groups: (1) pectin, 50 g of pectin per kilogram of diet, and (2) control, diet without dietary fiber. Iron was added to the diets for the two groups in order to reverse the anemia. During the iron deficiency anemia recovery phase (3 weeks), the pectin group showed lower mean values (p < 0.05) of weekly food intake (89.18 +/- 10.82; 107.60 +/- 11.70; 114.50 +/- 16.29 g, respectively, for the pectin group and 99.56 +/- 10.60; 116.36 +/- 15.33; 125.66 +/- 17.25 g, respectively, for the control group). the body weight of the pectin group was lower (p < 0.05) during the study's second and third weeks (192.42 +/- 16.67 and 228.75 +/- 19.81 g, respectively, and 202.87 +/- 19.96 and 243.51 +/- 20.44 g for the control group). Pectin led to a reduction in food intake and growth but not to iron absorption when taking into account the regeneration of hemoglobin mass.
