Randomized Controlled Trial
Effects of high β-glucan barley on visceral fat obesity in Japanese individuals: A randomized, double-blind study.
The aim of this study was to investigate whether a diet in which high β-glucan barley was substituted for rice would reduce visceral fat obesity in Japanese individuals. ⋯ The intake of high β-glucan barley led to significant and safe reductions in VFA, body weight, BMI, and WC in individuals with visceral fat obesity with VFA ≥100 cm2. Barley high in β-glucan may contribute to preventing visceral fat obesity.

Randomized Controlled Trial
Short-term effects of a low glycemic index carob-containing snack on energy intake, satiety, and glycemic response in normal-weight, healthy adults: Results from two randomized trials.
The potential positive health effects of carob-containing snacks are largely unknown. Therefore, the aims of these studies were to determine the glycemic index (GI) of a carob snack compared with chocolate cookie containing equal amounts of available carbohydrates and to compare the effects of a carob versus chocolate cookie preload consumed as snack before a meal on (a) short-term satiety response measured by subsequent ad libitum meal intake, (b) subjective satiety as assessed by visual analog scales and (c) postprandial glycemic response. ⋯ The carob snack led to increased satiety, lower energy intake at meal, and decreased postmeal glycemic response possibly due to its low GI value. Identifying foods that promote satiety and decrease glycemic response without increasing the overall energy intake may offer advantages to body weight and glycemic control.

Randomized Controlled Trial
Effect of 1-y oral supplementation with vitaminized olive oil on platelets from healthy postmenopausal women.
Olive oil is the main fat source in the Mediterranean diet and shows a protective role against aging and related diseases. Osteoporosis represents a serious health problem worldwide and is associated with an increased risk for fractures and mortality. Nutrition should be part of bone disease prevention strategies, especially in light of the aging population and the effect of diet on bone health. The aim of this study was to investigate whether oral supplementation with extra virgin olive oil (VOO) enriched with vitamins D3, K1, and B6 (VitVOO) is able to modify some physicochemical and functional plasma membrane properties and nitrosative stress markers status. ⋯ The supplementation of VitVOO into the diet of postmenopausal women could represent a proper tool for platelet function and a useful strategy against nitrosative stress and related diseases, thus confirming the antioxidant role played by the added vitamins.
