Nutritional management is an important component of modern diabetes treatment. In this study, healthful eating practices were advised to diabetic patients recruited at the establishment of Public Health and at the endocrinology department of Tlemcen University Hospital Center (West Algeria) and beneficial effects on glucose and lipid levels and on oxidative stress parameters were evaluated after 3-years of follow-up. At baseline, the results provide evidence that glucose, lipid metabolism and oxidant/antioxidant status are altered in type 1 diabetic patients. These metabolic abnormalities were associated to at risk dietary habits such as high intakes of simple carbohydrates, fat and cholesterol and low intakes of proteins, vitamin and fiber. Nutritional management improved dietary consumption and induced a decrease in metabolic abnormalities linked to diabetes after 3 years of follow-up.
