The effect of dairy and non-dairy beverages consumed with high glycemic cereal on subjective appetite, food intake and post-prandial glycemia in young adults

OBJECTIVE: To compare the effect of dairy and non-dairy beverages when consumed with carbohydrate at breakfast on subjective appetite, food intake (FI) and post-prandial glycemia (PPG) in healthy young adults.

DESIGN: Twenty-six healthy males and females (13 males and 13 females; 23.0 + 2.6 years; BMI: 22.3 + 1.5 kg/m2) participated in a randomized crossover study. They consumed non-isocaloric amounts (250 mL) of almond beverage, soy beverage, 1% fat milk, yogurt beverage and water (control) with cereal and 120 min later, an ad libitum meal. Subjective appetite, PPG and insulin were measured at baseline and at intervals before and after the meal at which FI was measured. RESULTS: Post-treatment blood glucose was lowest following soy beverage compared to all treatments but was not different from milk (p=0.0002). There were no differences between any other treatments. However, over the first hour, PPG for all treatments was 27% lower compared to water (p<0.0001). Milk and yogurt beverage led to the highest insulin concentrations post-treatment (p<0.0001) but there were no differences between treatments post-meal. All treatments reduced appetite and led to lower FI at the meal compared to water but FI was lower after milk compared to all treatments except yogurt beverage (p<0.0001).

CONCLUSION: Both dairy and non-dairy beverages consumed with a high glycemic cereal at breakfast increased satiety and decreased FI compared to water with cereal. Despite higher carbohydrate content, all beverages led to similar or lower PPG than the water breakfast but dairy beverages increased insulin more than non-dairy beverages.
