[Comparison of dietary intake of type I diabetic patients and nutritional recommendations].
BACKGROUND
The management of type I diabetes mellitus requires a careful balance between nutrient intake, energy expenditure and dose and timing of insulin. According to the recommendations of the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) the calories should be prescribed according to energy needs to achieve and maintain a desirable body weight. Many studies have shown that diets in which carbohydrates provide 50-60% of total energy are associated with improved blood glucose control and lower levels of LDL cholesterol. Whenever acceptable to the patients, natural foods containing unrefined carbohydrate should be substituted for the highly refined carbohydrates that are low in fiber. The high risk of macrovascular disease in patients with diabetes dictates a need to restrict total fat (25-30% of total energy) and cholesterol intake (300 mg/day). ADA and EASD suggest that reduction of protein intake (0.8 g/kg/day) may reduce proteinuria and progression to renal failure during the earliest stages of diabetic nephropathy.


METHODS
The goal of this study was to describe macronutrient intakes in type I diabetic patients of our Centre by a validated 3 day record.


RESULTS
Mean energy intake was 2022+/-427 Kcal/die (vs 2596+/-501 recommended intake). Average protein intake was well above the level of 0.8 g/kg/day required to ensure an adequate protein intake in type I diabetes mellitus. Total fats contributed 29.8+/-7.4 of total energy (vs 27% recommended intake) and saturated fat provided significantly more than 10% of energy. Carbohydrates intake was above 50% of total energy but fiber intakes was substantially lower than the recommendation (12.7+/-5.5 vs 20.1+/-6.6 g/day).


CONCLUSIONS
These data indicate current problems in the nutritional intake of type I diabetes mellitus; in fact the majority of our group of patients are not meeting the recommended dietary intakes for protein, total fat, saturated fat and fiber.
