Intervention / Treatment
Detailed Description
The study will be conducted with a randomized, double-blind, parallel-group (2 arms) placebo-controlled, single-center interventional design. The aim is to investigate the effects on cognitive function and cardiometabolic risk markers after acute and 12 weeks daily intake of a berry product vs. a reference product. The reference will be isocaloric and matched in taste, appearance, volume and macronutrient composition to the active berry product.
Two groups, each of 30 volunteers, are studied. One group of volunteers will consume the berry product while the other group act as control and will consume the reference product.
Each volunteer will be seen for a screening visit as well as one pre- and one post-intervention visit at the clinic. In addition, there will be 2 follow-up calls in between visits. Pre- and post intervention visits will include cognitive assessment with the CANTAB battery (episodic memory and verbal recognition memory), as well as additional cognitive and behavioral tests. Cardiometabolic parameters will be addressed (plasma glucose, insulin, inflammatory markers, blood lipids, body composition) and fecal samples collected.
