INTRODUCTION: To assess the effects of the habit of having evening dinner on the dietary macro- and micronutrient profile of chronic kidney failure patients on hemodialysis. METHODS: Cross-sectional study carried out at a dialysis clinic at the city of Belo Horizonte, state of Minas Gerais. The study comprised 90 patients undergoing hemodialysis. Personal, clinical, and dietary (three-day food record) data were collected. The habit of having dinner was considered as having a complete evening meal, and the lack of that habit was considered as not having it or replacing it by a fast meal. The amounts of nutrient intake were estimated in the specific software Dietwin®. RESULTS: The carbohydrate, thiamine, riboflavin, ascorbic acid, calcium, and selenium intake values showed no difference between the group having a complete evening meal and that not having it (p > 0.05). Both groups did not differ in the following: body mass index, and energy, protein, lipid, niacin, pantothenic acid, pyridoxine, folic acid, cobalamin, potassium, phosphorus, zinc, and magnesium intake values (p < 0.05). Regarding nutrient adequacy, the complete evening meal group performed better than the other group, except for carbohydrates, lipids, pantothenic acid, ascorbic acid, potassium, calcium, and zinc (p < 0.05). None of the patients showed the adequate pyridoxine, folic acid, and selenium intake values. Few patients in both groups showed adequate energy, pantothenic acid, and zinc intake values. CONCLUSION: The habit of having a complete evening meal influenced positively the micro and macronutrient intakes in chronic kidney failure patients on hemodialysis.
