Resumen
Nutritional deficiencies, especially micronutrient deficiencies, can occur in obese individuals. Surgical treatment may aggravate or cause these deficiencies, depending on the type of procedure, food intake and the use of multivitamins, minerals or other supplements. The objective of the study was to evaluate the nutrient intake of women who had undergone Roux-en-Y gastric bypass (RYGB) surgery. A cross-sectional, controlled study was conducted among 44 women after RYGB (operated-group, OG; mean years post-operation = 3.4) and a control group of 38 healthy women (non-operated group, NOG) matched by age and economic condition. The women reported their dietary intake using a 4-day record. The Dietary Reference Intakes was used as a reference. The macronutrient contributions to dietary energy intake presented an acceptable distribution for proteins and carbohydrates. Lipid intake was high among women in the OG and the NOG (43.2 and 55.3 %, respectively). In the evaluation of micronutrients, a statistically significant difference was observed between the groups for iron, zinc and vitamins B1 and B12. Both groups were at high risk for inadequate calcium intake, and the OG was at risk for inadequate zinc, iron and vitamin B1 intake. The nutrient intake of women who had undergone RYGB is very similar to that of non-operated women, with the exception of a reduced intake of iron, zinc and vitamins B1 and B12, which may be due to the difficulty of consuming meat and a balanced diet. The findings of this study emphasize the importance of appropriate nutritional intervention and the regular use of multivitamin and mineral supplements for these patients.
