RESUMO

The specialized literature has noted that the diet has a core function in the occurrence of cardiovascular diseases, playing a fundamental role in the prevention of such illnesses. A cross-sectional study carried out in the city of Ouro Preto, Minas Gerais in 2001, aimed analyzing food consumption by individuals older than fifteen years old, as well as verifying a possible association with the risk factors for heart diseases. Eight hundred seventy-one individuals were interviewed. The Questionnaire of Diet Frequency was used to evaluate regular ingestion of nutrients and standard values of Reference of Diet Ingestion were adopted. System hypertension, dyslipidemia, hyperglycemia and obesity were studied to explain risk factors for cardiovascular diseases associated with regular food consumption. The prevalence of hypertension was 50.3%, dyslipidemia 13.2%, diabetes 6.9% and obesity 13.1%. It was noted that among women the risk factors were proportional to age. Among men however, the proportionality was seen only in hypertension. The caloric contribution of carbohydrates and proteins was adequate (54 and 11%, respectively), but of the lipids it was slightly above of the recommended (36%). The average of vitamin A consumption was above of the recommended (7411ug), while vitamin E and C and selenium presented adequate ingestion (32 mg, 197 mg and 82 ug, respectively). The amount of cholesterol in the diet was excessive in 31% of individuals. Generally, men presented greater ingestion values than women, and such values tended to decrease with age in both sexes. Obese, dyslipidemic and diabetic individuals and the ones with high blood pressure have tended, to present lower values of ingestion related to values of healthy individuals. Vitamins A and C presented a significantly inverse relationship with dyslipidemia. Vitamin E was related equally with obesity and dyslipidemia. Selenium by its turn, presented an inverse and significant relation with all risk factors evaluated. Based on such information it was observed that the regular diet of the population of Ouro Preto presents adequacy in micronutrients related to the protection against Cardiovascular Diseases.
