According to the study, about 25% of drinkers claimed to be hangover-resistant.  So the questions are: Are there really people immune to a hangover? And can eating and drinking cure hangover? Scientists finally have answers to these questions.

Despite eating greasy foods and vitamin C and gulping liters of water, there is no way these can cure your hangover. This is according to a recent research presented in the ENCP conference in Amsterdam conducted by Dutch and Canadian scientists.

The study surveyed 789 students on the largest volume of drinking episode they had the previous month. Scientists obtained specific data from the participants. This includes the largest number of drinks they had, the timeframe the drinks were consumed and severity of the hangover. Then, they compared the blood-alcohol concentration (BAC) on those who had a hangover and those who did not.

Results revealed that many of those who claimed that they do not experience hangover fall in the BAC below 0.10%. Thus, this questions the claim that hangover immunity is possible.

Dr Joris Verster of Utrecht University says, "we have been working with Canadian and Dutch students on this issue. In general, we found a pretty straight relationship; the more you drink, the more likely you are to get a hangover. The majority of those who, in fact, reported never having a hangover tended to drink less, perhaps less than they themselves thought would lead to a hangover."

On the other hand, a separate research with 826 Dutch students participants seeks to determine the effect of drinking and eating on the severity of a hangover. After conducting studies on the students, the research concluded that severity of a hangover is not affected by consuming food or drinking water before sleeping or during a hangover.

"Those who took food or water showed a slight statistical improvement in how they felt over those who didn't, but this didn't really translate into a meaningful difference. From what we know from the surveys so far, the only practical way to avoid a hangover is to drink less alcohol," Dr. Joris Verster said.

More research is thus needed. As for now, moderate consumption of alcohol is the only effective method.
