The aim of the present study was to assess energy and nutrient intake in a group of women with restrictive AN (r-AN) compared with a control group. Thirteen r-AN patients and 13 healthy female controls completed 7-d food records. Intake of macro- and micronutrients was compared between the two groups as well as to the Dietary Reference Intake for the Italian Population (LARN) for specific ages. Additionally, the r-AN patients underwent indirect calorimetry for measuring resting energy expenditure (REE). Total energy intake was significantly lower in the r-AN group than in controls (906 ± 224 vs 1660 ± 139, respectively; P < 0.01). Nutrient composition significantly differed, as well. Mean intake of sodium, phosphorus, and zinc was higher in controls than in the women with r-AN (P < 0.01), but neither group of women met LARN recommendations for potassium, calcium, or iron intake. With respect to vitamins, no significant differences were found for riboflavin or vitamins A, B12, or C between groups, whereas levels of other vitamins differed (P < 0.01). Both groups failed to meet the LARN recommendation for vitamin D intake; moreover, none of the r-AN patients met recommended intake levels of vitamin E, thiamine, niacin, and folate. Intakes reported by r-AN patients did not meet requirements for most micronutrients evaluated in this study and, as expected, both energy needs and specific dietary patterns differed between groups. Therefore, a careful evaluation of food consumption should be recommended to reduce nutritional gaps in these patients. According to these preliminary observations, nutritional counseling, mainly focused on calcium and vitamin D intake, should be suggested for healthy women, as well.
