Clinical Trial Summary

The effects of strawberry and sea buckthorn on postprandial glycaemia and insulinemia as well as on metabolic profiles were examined in overweight or obese male subjects. The study was conducted as a randomised, controlled, single-blinded, 3-way crossover study. Eighteen subjects were studied in three 2 h meal tests followed by a subsequent ad libitum meal. Test meals contained either sea buckthorn, strawberry or no berries and added sucrose to match with respect to sucrose content. Blood samples were collected at baseline and several times postprandially. Subjective appetite sensations were recorded at baseline and every 15-20 min until 140 min and a subsequent ad libitum intake was recorded. Urine samples were also collected at baseline and at several time intervals until 24 hours. Blood and urine were subjected to metabolic profiling to investigate potential biomarkers of berry intake.


Description:

Purpose: Berries and mixed berry products exert acute effects on postprandial glycaemia and insulinemia, but very few berries have been studied, and primarily in normal weight subjects. Sea buckthorn and strawberry are compositionally widely different berries and may likely produce different responses. The effects of strawberry and sea buckthorn on postprandial glycaemia and insulinemia were examined in overweight or obese male subjects. Subjective appetite sensations and ad libitum intake were also examined. Berries may thus improve health in longer studies; however, accurate assessment of berry intake is still problematic. The discovery of objective biomarkers for intake of berries is therefore important in assessing both intake and compliance. The investigators aimed to identify urinary exposure markers of two very different berries, strawberry and sea buckthorn, in humans.

Methods: The study was conducted as a randomised, controlled, single-blinded, 3-way crossover study. Eighteen subjects were studied in three 2 h meal tests followed by a subsequent ad libitum meal. Test meals contained either sea buckthorn, strawberry or no berries and added sucrose to match with respect to sucrose content. Blood samples were collected at t = 0, 30, 45, 60, 90 and 120 min. Subjective appetite sensations were recorded at t = 0, 15, 30, 45, 60, 90, 120 and 140 min and subsequent ad libitum intake was recorded. Statistical differences in all continuous measures were evaluated based on the existence of a meal or a time-meal interaction by repeated measurements analyses or differences in the area under the curve (AUC) for that measure in a linear mixed model. Urine samples were collected on each test day at t=-15min, t=0-1h, t=1-2h, and t=2-24h and were analyzed by untargeted metabolomics. Multivariate analysis was applied to discover markers, followed by molecular fragmentation to ease their chemical identification.

Other:
Meal sequence 1-2-3
The subjects were studied in three 2 h meal tests with a subsequent ad libitum meal on separate days, at least two days apart. The subjects were individually randomised to the sequence of the test meals using random permutation. The study included two berry meals based on 150 g of frozen berries; sea buckthorn (Hippophaë rhamnoides) and strawberry (Fragaria x ananassa), respectively, and one control meal which did not contain berries. Each meal contained 35 g of sucrose and was adjusted for protein and fat with whey protein and canola oil, respectively. The meals were served with 120 mL of water.
Meal sequence 1-3-2
