The Benefits of Consuming Hummus as an Afternoon Snack

30. April 2019 aktualisiert von: Heather Leidy, Purdue University

The Benefits of Consuming Hummus as an Afternoon Snack on Appetite Control, Daily Food Intake, and Diet Quality in Adults

The investigators propose a randomized snack study in normal to overweight adults that will test whether the consumption of different afternoon snacks will have different effects on appetite, mood, blood sugar control, and food intake.

Aim 1: To examine whether the addition of hummus as part of an afternoon snack will improve diet quality, particularly through assessments of daily:

  • Vegetable consumption
  • Snacking behavior
  • Energy intake
  • Food choices

Aim 2: To examine whether the addition of hummus as part of an afternoon snack will improve appetite control and satiety including assessments of:

  • Appetite Control (hunger, desire to eat, prospective food consumption)
  • Cravings (sweet, salty, savory)
  • Satiety (fullness)
  • Eating initiation

Aim 3: To examine whether the addition of hummus as part of an afternoon snack will improve free-living glycemic control.

Aim 4: To explore whether the addition of hummus as part of an afternoon snack will improve mood/energy states

Detaillierte Beschreibung

Experimental Design: For 6 consecutive days/treatment, the participants will consume either hummus and pretzels, granola bars, or no snack between 2-4 pm and refrain from eating anything else during this time. On day 7, the participants will consume a standard breakfast, at home, and will come in to the investigator's facility 1 h prior to their habitual lunch time. The participants will be placed in a comfortable room, void of all time cues and a standardized lunch will be consumed. At 3 h after lunch, the participants will complete baseline appetite, satiety, and mood questionnaires. The respective snack will be given to the participants, and they will have 20 minutes to eat the snack. Snack palatability will also be assessed. The participants will continue to complete the previous questionnaires until they voluntarily choose to eat (again). At 3 h after snack, they will be presented with ad libitum dinner and evening snacks. They will be permitted to eat as much or as little as they would like to eat over the remainder of the day. In addition, from day 3 to day 8 of the testing week, continuous glucose monitoring will be completed to assess glucose control.

Ad libitum Snack Pack-out
Zeitfenster: 3 testing days
Free-living energy intake will be assessed on the in-clinic testing day of each treatment. When the participant leaves the testing facility, the participant will be provided with an excess of snacks to consume, ad libitum, throughout the remainder of the day. The quantity of food provided will be ~50% more than their estimated, weight-maintaining energy intake. All food items will be initially weighed and recorded. The participants will be instructed to return all uneaten foods as well as all wrappers and containers from consumed food. Any partially eaten, returned items will be weighed accordingly. The daily energy content will be assessed from these pack-outs.
3 testing days
Glucose Excursions Change
Zeitfenster: 6 days for each treatment
Free-living, glucose measures will be performed for 7 consecutive days using Continuous Glucose Monitoring Device. The participants will report to our facility during one afternoon for insertion. A small area on the participant's abdomen will be cleaned and the tiny glucose sensor will be inserted just under the skin and held in place with Tegederm. The sensor measures glucose every 10sec and records an average glucose value every 5min for up to 144h.Calibration is performed by 4 finger sticks/d with a glucose analyzer.
6 days for each treatment
Perceived Snack Palatability
Zeitfenster: 2 testing days that include snacks
A questionnaires assessing how much the snack is liked will be completed at specific times throughout the 4-h testing days. The questionnaire contains a 100 mm VAS incorporating a horizontal line rating scale for each response. The questions are worded as "how strong is your feeling of" with anchors of "not all" to "extremely." The range is 0 mm (min) to 100 (max). A summation (area under the curve) will be calculated.
