[Nutritional habits of homozygote beta-thalassemic subjects].
An investigation on eating habits of a group of 40 patients with beta-thalassemia major has been carried out mainly to evidentiate iron intake whose absorption is strikingly increased in this disease. Questionnaires were used to obtain information. Daily food intake, the mean consumption of various types of food and the level of the more significant nutrients were calculated, using the National Institute of Nutrition tables. A high consumption of meat and a low consumption of fruits and vegetables were observed. A high proportion of proteins (particularly of animal origin) and a low proportion of lipids and carbohydrates was observed in comparison with the recommended levels of nutrients. Iron intake was slightly lower but its absorption may be increased because of the high proportion of calories of animal origin. A manipulation of the diet seems to be necessary to reduce the risk of iron loading.
