Impact of a Nutritional Intervention on Type1 Diabetes Adult With Metabolic Syndrome (MEDIT)

29. januar 2019 opdateret af: Institut de Recherches Cliniques de Montreal
Recent studies have found that up to 45 % of patients with type 1 diabetes have metabolic syndrome, a cluster of conditions (abdominal obesity, hypertension, dyslipidemia, insulin resistance) that increase the cardiovascular risk. The investigators have observed in previous studies a strong association between the adherence to a Mediterranean diet and the prevalence of metabolic syndrome on patients with metabolic syndrome. However, no intervention has been realized on this population and the current recommendations (low fat diet) differ from the Mediterranean diet. A nutritional intervention on the principles of the Mediterranean diet could therefore play a role in the treatment of the metabolic syndrome in Type 1 diabetes patients. The main objective of this study is to examine the impact of a nutritional intervention on the waist circumference after 6 months of an intervention group (Mediterranean diet) versus a control group (low fat diet).

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: Mediterranean Diet
Participants will receive nutritional lessons on the principles of the Mediterranean diet. This type of diet is defined with a carbohydrate intake of 45-55% of total energy intake, 15-20% of proteins, 30-35% of lipids and less than 7% for saturated fat. Nine sessions with a nutritionist are planned to cover various topics of the diet.
Adfærdsmæssigt: Nutritional Counseling
Carbohydrate counting will be reviewed, as well as hypoglycemia management. The 9 following visits will focus on different aspects of each diets: types of fats, meat and alternatives, grain products, milk and alternatives, fruits and vegetables, salt intake, energy density and restaurants.
Placebo komparator: Low Fat Diet
Participants will receive nutritional lessons on the principles of the low fat diet. This type of diet is defined with a carbohydrate intake greater than 45% of total energy intake, 15-20% of proteins, less than 30% of lipids and less than 7% for saturated fat. Nine sessions with a nutritionist are planned to cover various topics of the diet.
