Objective: The objective of this study was to evaluate the meal patterns and nutrient intake of women with bulimia nervosa (BN), and to compare them to clinical variables and recommended dietary allowances (RDA). Method: The nutrient intake of 50 women with BN was analyzed from 14 day dietary records. The data were compared to the median intakes of a random sample of women and to the RDA. Clinical variables for the women with BN were also available. Results: Compared to nonbinge episodes per day, binge eating was significantly higher in energy from sucrose, fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and lower in protein. Compared to the population median, binge eating was significantly lower in percent energy from protein, and higher in percent carbohydrate (CHO), sucrose, SFA, and MUFA, while nonbinge eating was significantly lower in percent energy from fat, SFA, and MUFA. Total intakes were significantly higher in energy and percent energy sucrose compared to the population. Despite significantly lower nonbinge energy intake, calcium, vitamins A and C, iron, and folate were not significantly different to the population median. However, one half or more of the subjects had less than two-thirds the RDA for nonbinge calcium, iron, zinc and for total intake one fourth remained less than two-thirds the RDA for iron and zinc. Conclusion: Nonbinge eating was characterized by low energy intake and by low intake of iron, calcium, and zinc. Binge eating, characterized by high sucrose and SFA content, overcompensated for these low energy intakes. Where treatment reduces or eliminates binge eating, it should also encourage consumption of regular meals and in particular, consumption of foods rich in zinc and iron.
