Evaluating a dietary pattern in adolescents with type 1 diabetes mellitus: The dash-d approach.

Objective: Adolescents with type 1 diabetes (T1DM) must consider multiple factors in diet planning, including glycemic control and cardiovascular disease prevention, while ensuring adequate nutrition for growth. We examined diet composition, quality, and compliance for two dietary patterns - the traditional Dietary Approaches to Stop Hypertension (DASH) and a modified version of DASH in this population.

Methods And Findings: Two feeding studies were conducted.

PAR2 (Protease-Activated Receptor 2) Deficiency Attenuates Atherosclerosis in Mice.

Objective: PAR2 (protease-activated receptor 2)-dependent signaling results in augmented inflammation and has been implicated in the pathogenesis of several autoimmune conditions. The objective of this study was to determine the effect of PAR2 deficiency on the development of atherosclerosis.

Approach And Results: PAR2 mRNA and protein expression is increased in human carotid artery and mouse aortic arch atheroma versus control carotid and aortic arch arteries, respectively.

Effects of the dietary approaches to stop hypertension (DASH) diet on glucose variability in youth with Type 1 diabetes.

Objective: Glucose variability (GV) independently increases risk for vascular events in patients with diabetes. The Dietary Approaches to Stop Hypertension (DASH) dietary pattern emphasizes fruits, vegetables, whole grains, lean meats, and low fat dairy and has the potential to reduce postprandial blood glucose (BG) excursions, however, its effect on GV is not known. The purpose of this work was to assess feasibility and collect preliminary data on the efficacy of the DASH diet on GV in adolescents with type 1 diabetes (T1D).

Effects of acute ingestion of different fats on oxidative stress and inflammation in overweight and obese adults.

Background: Studies show that obese individuals have prolonged elevations in postprandial lipemia and an exacerbated inflammatory response to high fat meals, which can increase risk for cardiovascular diseases. As epidemiological studies indicate an association between type of fat and circulating inflammatory markers, the purpose of this study was to investigate the acute effect of different fat sources on inflammation and oxidative stress in overweight and obese individuals.

Methods: Eleven overweight and obese subjects consumed three high fat milkshakes rich in monounsaturated fat (MFA), saturated fat (SFA), or long-chain omega 3 polyunsaturated fat (O3FA) in random order.
