Slowly Digestible Carbohydrates for GLP-1 Secretion
The goal of this clinical trail is to learn if the hormone, glucagon-like peptide-1 (GLP-1), is stimulated by slowly digestible carbohydrates (SDCs) in healthy adults. In the current study, researchers will observe the amount of SDC that results in clinically meaningful levels of GLP-1, shown by an increase in feelings of fullness and a decrease in hunger, and how long an elevated level of GLP-1 lasts after starch consumption. Researchers aim to address two questions: What amount of SDC maximizes GLP-1-mediated satiety, and does the impact to satiety continue in a second meal? The overall goal is to maximize ileal-digesting SDC's potential use as a food-based agent for weight loss.
Researchers will compare 20, 40, and 60 g of raw corn starch compared to a maltodextrin control on total plasma GLP-1 concentrations, insulin, and blood glucose at baseline and 15, 30, 60, 90, 120, and 180 minutes post-consumption of SDC. Researchers will also measure satiety at baseline, 60, 120, 180 minutes and after a second meal.
There will be a total of 4 study visits with a least a 7-day break between visits. At each study visit, participants will:
- Consume a randomized test beverage (SDC or maltodextrin)
- Receive a blood draw at 7 timepoints over 3 hrs
- Take a satiety questionnaire 5 times over 3 hrs
- Consume a standardized lunch 3 hrs after the test beverage consumption

Comparador de placebos: Maltodextrin
Maltodextrin increases GLP-1 from 0-60 minutes but doesn't have an extended or elevated plasma GLP-1 into 2-3 hrs post-consumption.
Participants will consume a treatment that is either entirely maltodextrin or partially maltodextrin during each of the 4 study visits.
|
75 g of maltodextrin diluted in 200 mL of water, taken once at a study visit

Experimental: Low-Dose SDC
20 g of raw corn starch (SDC) + 55g of maltodextrin = 75 g total Researchers hypothesize that raw corn starch will have an extended or elevated plasma GLP-1 into 2-3 hrs post-consumption.
Participants will consume the low-dose once during one of the study visits.

75 g of maltodextrin diluted in 200 mL of water, taken once at a study visit
Otros nombres:
Quantity of raw corn starch will vary between low, medium, and high-dose treatment arms (20, 40, 60 g respectively).
Each treatment will total 75 g using maltodextrin to account for mass difference (55, 35, 15 g respectively).

Participants will consume the medium-dose once during one of the study visits.
