Regular Aerobic, Resistance, and Cross-Training Exercise Prevents Reduced Vascular Function Following a High Sugar or High Fat Mixed Meal in Young Healthy Adults.

The postprandial state can negatively influence flow mediated dilation (FMD), a predictor of atherosclerosis and cardiovascular disease. This investigation was designed to determine the effect of regular aerobic and/or resistance exercise on postprandial FMD after a high sugar or high fat mixed meal. Forty-five healthy participants were recruited from one of four groups: lean sedentary (SED), runners, weight lifters, and cross-trainers.

Probiotic yogurt for the treatment of minimal hepatic encephalopathy.

Objectives: Minimal hepatic encephalopathy (MHE), the preclinical stage of overt hepatic encephalopathy (OHE), is a significant condition affecting up to 60% of cirrhotics. All MHE therapies modify gut microflora, but consensus regarding MHE treatment and long-term adherence studies is lacking. The aim was to determine the effect of probiotic supplementation in the form of a food item, probiotic yogurt, on MHE reversal and adherence.

Benefit of low-fat over low-carbohydrate diet on endothelial health in obesity.

Obesity is associated with impaired endothelial-dependent flow-mediated dilation, a precursor to hypertension and atherosclerosis. Although dieting generally improves cardiovascular risk factors, the direct effect of different dietary strategies on vascular endothelial function is not known. The purpose of this study was to test the hypothesis that a low-fat (LF) diet improves endothelial function compared with an isocaloric low-carbohydrate (LC) diet.

Influence of glycemic load on HDL cholesterol in youth.

Background: The influence of dietary carbohydrate glycemic index on blood lipids has not been well studied. Assessment of glycemic load is not usually included in a standard dietary analysis.

Objective: The purpose of the present study was to examine relations between diet and blood lipids in youth with a broad range of cholesterol values and carbohydrate, fat, and protein intakes.
