Effects of Goat Milk Yogurt on Postprandial Glycemic Responses, Arterial Blood Pressure and Energy Intake

Summary

This study investigated any potential associations between two preloads offered as snacks and postprandial glycemic response, subjective appetite and energy intake in healthy, normal weight adults

Conditions

• Potential Abnormality of Glucose Tolerance
• Appetite; Lack or Loss, Nonorganic Origin

Interventions

OTHER

Glucose as reference food

Twelve subjects (male: 4 female: 8) consumed 25g glucose diluted in 150ml water, two times, in different weeks, within 5-10 min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120 min.

OTHER

Goat milk as test food

Twelve subjects (male: 4 female: 8) consumed 617 g goat milk yogurt, offering 25g available carbohydrate along with 250 mL water, one time, in different weeks, within 10-15 min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120 min.

OTHER

Goat milk and currants as test food

Twelve subjects (male: 4 female: 8) consumed 308 g goat milk yogurt and 19 g currants, offering 25g available carbohydrate along with 250 mL water, one time, in different weeks, within 10-15 min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120 min.

OTHER

Currants as test food

Twelve subjects (male: 4 female: 8) consumed 37.8 g currants, offering 25g available carbohydrate along with 250 mL water, one time, in different weeks, within 10-15 min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120 min.

OTHER

Sultanina raisins as test food

Twelve subjects (male: 4 female: 8) consumed 37.5 g sultanina raisins, offering 25g available carbohydrate along with 250 mL water, one time, in different weeks, within 10-15 min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120 min.

OTHER

Goat milk yogurt as preload

Forty-five healthy subjects (male: 12, female: 33) consumed a standardized breakfast (bread and honey) and 2h after were offered a preload given as snack (200g goat milk yogurt). Three hours after, subjects were given ad libitum access to a meal (lunch and dessert). The meal consisted of rice, roasted chicken breast and chocolate vanilla cake. Foods were weighed before serving and any leftovers were weighed again after meal. Fingertip capillary blood glucose samples were taken before breakfast, 120min after breakfast; before preload, 120minand 180minpost-preload consumption; before meal (lunch and dessert), 60minand 120min post-meal consumption. Subjective appetite ratings were assessed with 100mm VAS.

OTHER

Milk with lactic acid as preload

Forty-five healthy subjects (male: 12, female: 33) consumed a standardized breakfast (bread and honey) and 2h after were offered a preload given as snack (200g milk with lactic acid). Three hours after, subjects were given ad libitum access to a meal (lunch and dessert). The meal consisted of rice, roasted chicken breast and chocolate vanilla cake. Foods were weighed before serving and any leftovers were weighed again after meal. Fingertip capillary blood glucose samples were taken before breakfast, 120min after breakfast; before preload, 120minand 180minpost-preload consumption; before meal (lunch and dessert), 60minand 120min post-meal consumption. Subjective appetite ratings were assessed with 100mm VAS.
