- Public TitlePEANUTS Study
- Scientific TitlePeanut protein detection in serum and exercise
- ACRONYMPEANUTS Study
- hypothesisWith a recently developed Ara h6 ELISA we would like to show the effect of exercise on circulating Ara h6 after peanut consumption
- Healt Condition(s) or Problem(s) studiedHealthy volunteers, Food allergy
- Inclusion criteria- 20-35 year old males and females
- Body mass index (BMI) 23-27.5 kg/m2
- Suitable veins for blood sampling
- No inhibitory matrix effect in Ara h6 ELISA method
- Able to cycle 1h on ergometer

- Target number of participants10
- InterventionsIntake of 100grams of roasted peanuts during 2 test days Intake of 5g Lactulose and 1gr L-rhamnose during two test days
Blood sampling via venflon cannula at baseline and 30, 60, 90, 120, and 240 min after peanut intake during two test days.
Cycling on ergometer 1hr 75% Wmax during 1 test day
- Primary outcomeThe main study parameter is the difference in serum Ara h6 levels over time between a resting and an exercise condition
- Secondary outcomeThe secondary endpoint is the level of exercise-induced permeability
Other outcomes: Body weight, height, intestinal integrity-related markers, such as I-FABP
- TimepointsBlood is sampled at baseline and at T=30, 60, 90, 120, and 240min after peanut consumption. Levels of Ara h6 will be analysed in serum samples collected at each of the time points with the sandwich ELISA method. Plasma levels of lactulose and rhamnose will be analysed in plasma samples collected at baseline and T=60min after peanut consumption. I-FABP will be measured in plasma samples collected at baseline and at T=30 and T=60 min after peanut consumption.

- Brief summaryIn this intervention study 10 healthy participants will ingest 100grams of peanuts and a dual sugar solution during rest (day 1) or with following exercise (day 2, 75%Wmax cycling). A recently developed ELISA method will be used to assess the effect of exercise on circulating levels of Ara h6 after peanut intake and intestinal permeability will be determined.
