is a diuretic which promotes dehydration that can lead to headaches (such as the case often experienced with hangovers), indicating a need to maintain hydration when drinking wine and to consume in moderation. A 2017 review found that 22% of people experiencing migraine or tension headaches identified alcohol as a precipitating factor, and red wine as three times more likely to trigger a headache than beer. Food intake A serving of red or white wine provides about of food energy, while dessert wines provide more. Most wines have an alcohol by volume (ABV) percentage of about 11%; the higher the ABV, the higher the energy content of a wine. Psychological and social Danish epidemiological studies suggest that a number of psychological health benefits are associated with drinking wine. In a study testing this idea, Mortensen et al. (2001) measured socioeconomic status, education, IQ, personality, psychiatric symptoms, and health related behaviors, which included alcohol consumption. The analysis was then broken down into groups of those who drank beer, those who drank wine, and then those who did and did not drink at all. The results showed that for both men and women drinking wine was related to higher parental socioeconomic status, parental education and the socioeconimic status of the subjects. When the subjects were given an IQ test, wine drinkers consistently scored higher IQs than their counterpart beer drinkers. The average difference of IQ between wine and beer drinkers was 18 points. In regards to psychological functioning, personality, and other health-related behaviors, the study found wine drinkers to operate at optimal levels while beer drinkers performed below optimal levels. As these social and psychological factors also correlate with health outcomes, they represent a plausible explanation for at least some of the apparent health benefits of wine. However, more research should be conducted as to the relationship between wine consumption and IQ along with the apparent correlations between beer drinkers and wine drinkers and how they are different psychologically. The study conducted by Mortensen should not be read as gospel. Wine and Beer being an indicator of a persons IQ level should be viewed with a very cautious lens. This study, from what we know, does not take into account the genetic, prenatal and environmental influences of how a persons generalized intelligence is formed. In current scientific literature, it is still a matter of debate and discovery as to what are true
