Consumption of oats is associated with lowered risks of type 2 diabetes and obesity. However, many oat-based products (e.g.

Background: Rice and pasta are recommended as healthier than potatoes on the basis of their glycemic index when eaten alone.

Objectives: The study objective was to evaluate postprandial glycemia (PPG), appetite, and food intake (FI) at meals with potatoes or rice when consumed with either meatballs or their vegetarian substitute.

Methods: In a randomized, single-blinded, crossover design, 26 (13 males and 13 females) healthy adults (age: 18-45 y; body mass index [kg/m]: 18.

Plant-based food demand is rapidly increasing. However, the metabolic responses of plant proteins within their commercially available form remains unclear. Two randomized crossover experiments compared plant-based alternatives to dairy on postprandial glycemia, metabolic hormones, and appetite before and after a fixed size (12 kcal/kg body weight) pasta meal in sixteen healthy young adults (eight males and eight females).

Background: Dairy consumption reduces postprandial glycemia and appetite when consumed with carbohydrates.

Objectives: The objective was to test the effects of frequently consumed dairy products, age, and sex on glycemia, appetite, and food intake.

Methods: In a randomized, unblinded, crossover design, 30 older [60-70 y; BMI (kg/m2): 18.

Background: Increasing the total protein content and reducing the casein to whey ratio in milks consumed with breakfast cereal reduce postprandial blood glucose (BG).

Objectives: We aimed to explore associations between plasma amino acids (AAs), BG, and glucoregulatory hormones.

Methods: In this repeated-measures design, 12 healthy adults consumed cereal (58 g) and milks (250 mL) with 3.

This study describes the effects on glycemic response and the underlying mechanisms of action of increasing the protein concentration and decreasing the casein-to-whey ratio in milk when consumed with a high glycemic breakfast cereal. Twelve healthy men and women, aged 18 to 30 yr and with a body mass index of 20 to 24.9 kg/m, consumed (in random order) milk beverages (250 mL) containing either 3.

Dairy proteins reduce appetite and improve postprandial glycaemic response in adults. However, there are no reports of dairy in amounts usually consumed on satiety and postprandial glycaemia in either young or older adults. In a randomized crossover design, 30 healthy young adults (age: 23.

The objective was to compare the effect of liquid, semi-solid, and solid dairy products and a nondairy beverage when consumed with glycemic carbohydrate on subjective appetite, food intake (FI), and post-prandial glycemia (PPG) in healthy older adults. Thirty healthy men and women (14 males and 16 females; age: 64.6 ± 2.

The objective was to compare the effect of dairy and nondairy beverages when consumed with carbohydrate at breakfast on subjective appetite, food intake (FI), and postprandial glycemia (PPG) in healthy young adults. Twenty-six healthy males and females (13 males and 13 females; 23.0 ± 2.

The effect of beverages commonly consumed by children in-between or with meals on short-term food intake (FI) and glycemic control has received little attention. Therefore, 2 experiments were conducted in 9- to 14-year-old children following a randomized repeated-measures design. Experiment 1 (n = 32) compared the effects of water (control) and isocaloric (130 kcal) amounts of 2% milk, chocolate milk, yogurt drink, and fruit punch on subjective appetite and FI.

Puberty is a period of development that alters energy intake patterns. However, few studies have examined appetite and food intake (FI) regulation during development of puberty in children and adolescents. Therefore, the objective was to measure the effect of pubertal status on FI and subjective appetite after pre-meal glucose and whey protein drinks in 9- to 14-year-old boys and girls.

Background And Objectives: Delayed puberty and lower levels of testosterone (T) have been observed in adult obese males and some adolescent males. In adult men, enteral glucose ingestion results in acute lowering of serum testosterone levels; however, this has not been studied in adolescents. We aimed to examine the acute effect of a glucose/protein beverage on serum T concentration changes in obese peripubertal males.

Background And Objectives: Little information is available on how food intake regulatory hormones may be altered during pubertal development and across the weight spectrum in adolescents. Therefore, the effect of obesity, sex and pubertal status on subjective appetite and appetite hormones in response to a mixed glucose and whey protein drink was determined in 8-18 year old adolescents.

Patients And Methods: A cross-sectional cohort study was conducted at the Hospital for Sick Children, Toronto.
