Arm && Interventions

Group	Intervention	Description
Drink with 50 g glucose	glucose	The glucose drink contains 50 g of glucose soluted in 250 ml of water and lemon juice.
Drink with 100 gram of sacharose	sacharose	The sacharose drink contains 100 g of sacharose soluted in 250 ml of water and lemon juice.
Placebo with sweeteners	Placebo	The placebo contains a mixture of artificial sweeteners in order to have the same sweetness and appearance of the test drinks (the glucose drink and the sacharose drink).

Primary Outcome Measures

Name	Time	Method
Performance on the paired associate recall test	cognitive tests will start 15 minutes after ingestion of the intervention product	Cognitive performance will be assessed by several sensitive tests. Power is calculated on the paired associate recall test, but also several other cognitive performance test focusing on memory, attention and reaction time will be performed

Secondary Outcome Measures

Name	Time	Method
Mood	within 15 minutes after consuming the test drink and after completing the cognitive tests (within 90 minutes after consuming the test drink)	Mood will be measured by the POMS, after consuming the test drink, and after completing the congitive tests.
Blood glucose response	from baseline till 90 minutes after consuming the drink	Blood glucose will be measured at five time points, at t=0, after 15 minutes, 30, 60 and 90 minutes.
Plasma insulin levels	At t= -15 minutes, before consuming the test drink	One venapunction will be carried out at baseline to measure plasma insulin levels.
