[Plasma lipoprotein levels in relation to dietary habits].

We carried out a nutritional and haematological survey on 130 pupils of a boarding school in Cagliari in order to determine the relationship between plasma lipoprotein and nutritional habits, particularly, we determined beta/alpha ratio of lipoprotein comparing it with plasma values in hospitalized patients, suffering from metabolic and cardiovascular disease. The results allowed us to observe that 92% of hospitalized patients and 17% of subjects, presumably in good health, showed beta/alpha ratio greater than 2,5. The latter, apparently insignificant, is very important because it was detected in young subjects; as their diet was high-fat and high-carbohydrate, a nutritional and haematological survey will be always necessary in order to prevent illnesses.
