Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Research on glycemic control related to nuts or whole snack foods has focused primarily on tree nuts. Different processing and cooking methods have not been comprehensively analyzed to observe the effect on nutrient quality, bioavailability, or digestive absorption in peanuts. There is little to no research surrounding the nutrition of boiled peanuts so it may be of interest to compare boiled to roasted peanuts in terms of glycemic control. Peanuts have been shown to have a similar beneficial effect on glycemic control while being more financially accessible than almonds. Glycemic control could be improved based on the low glycemic index, high fiber, lipid, and or protein content of peanuts. The acute trial (phase 1) will investigate the impact of preprandial peanut consumption on glycemic response. The participants will complete an oral glucose tolerance test for both roasted and boiled peanuts. The long term study (phase 2\&3) consists of participants consuming one serving per day of boiled or roasted peanuts in a four week crossover trial to observe any long term impact of daily peanut snacking on glycemic control. (Wash out weeks occurring between all trials.) At the conclusion of phase 2 \& 3 an oral glucose tolerance test will be executed. The subjects will self record a exercise/step count and diet dairy, weight and waist to hip ratio will be measured weekly. The study will aim for a male and/or female healthy population from 18-65 years of age at NCSU.
