- Brief Summary
Rationale
It has been shown in several studies that alcohol increases subsequent food intake. However, moderate alcohol consumption has no clear effects on hunger and satiety hormones. In the Western world, where palatable food is highly available, food reward may play an important role in food intake. Alcohol consumption is known to stimulate neurotransmitters important for food reward and may therefore stimulate the reward response on a subsequent meal. This may lead to higher food consumption than when no alcohol is consumed. It is hypothesized that the reward response of food or beverages can already be generated when food or beverages are sensed in the mouth, because oral nutrient sensing is known to induce a satiety response (i.e. the cephalic phase response). Moreover, taste buds directly signal brain areas closely connected to the reward areas in the brain.
Primary objective
* To determine whether moderate alcohol consumption influences subsequent food reward, as measured by questionnaires on food 'wanting' and food 'liking', and salivary and blood parameters related to reward.
Secondary objectives
* To determine whether food reward is different when food is consumed than when food is sensed in the mouth, as measured by questionnaires on food 'wanting' and food 'liking', and salivary and blood parameters related to food reward.

- Primary Outcome Measures
Name Time Method Explicit food 'wanting' up to 75 minutes Questionnaire measuring food 'wanting' explicitly with the question: "How much do you want to eat at this moment?" This is scored on a visual analogue scale ranging from 0-100.
Implicit food 'wanting' for different food categories up to 30 minutes Computer task measuring food 'wanting' implicitly for different food categories. This is a forced choice task in which subjects have to choose as quick and precise the food product they want to eat most at that moment.
explicit food 'wanting' for different food categories up to 30 minutes Questionnaire measuring food wanting explicitly for different food categories on a visual analogue scale (ranging 0-100).
explicit food 'liking' for different food categories up to 30 minutes Questionnaire measuring food 'liking' for different food categories on a visual analogue scale (ranging 0-100).
