A tall glass of milk to line the stomach. Bouts of water between drinks. Pre-loading with carbs. Everyone, it seems, has their own tried and true method for preventing hangovers (how often they actually work is a different story altogether). But sure-fire ways of sidestepping the dreaded headaches, nausea and general discombobulation that can follow drinking sessions are rarely scientifically studied, instead living in the realms of onions-in-your-socks-to-prevent-colds-type remedies.
Yes, the search for a miracle prevention of hangovers has been fruitless – until now.
The pears have it
We’ve been researching pears with Horticulture Innovation Australia to discover the hidden benefits of the humble backyard fruit – beyond being cheaper than apples.
As well as finding that pears can lower cholesterol, relieve constipation and have anti-inflammatory effects, it also appears they can ward off hangovers AND lower blood alcohol levels.
In what could be one of the greatest ‘stumbled upon’ scientific findings since we discovered fast WiFi, this secret pear power has the potential to stimulate Friday afternoon pear purchases world-wide.
But before we get too far ahead of ourselves…
We spoke to Professor Manny Noakes, our lead researcher on the project, to get the full slice on pears.
Are there any types of pears that work better than other? And what’s the best way to consume them?
At present, studies have only investigated the Korean (or Asian) pear, which has long been used as a traditional remedy for alcohol hangover. A number of compositional differences have been noted between the Korean pear and Western pear varieties, so further studies are needed to confirm these findings to determine whether these results could be replicated using other pear varieties. So far the effect has been seen from consuming 220ml Korean pear juice, although consumption of whole pears may produce a similar effect.
How exactly do the pears prevent hangovers – how did we find this out?
There may be several ways by which pears could prevent hangovers. Our review has uncovered both animal and human studies trying to answer this question. It appears that the factors in Korean pears act on the key enzymes involved in alcohol metabolism, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) to speed up alcohol metabolism and elimination or inhibition of alcohol absorption. In particular, reductions were seen in blood acetaldehyde levels, the toxic metabolic thought to be responsible for the hangover symptoms, with pear juice consumption.
What hangover symptoms can pears prevent?
Overall hangover severity, as measured by a 14 item hangover symptom scale, was significantly reduced in the Korean pear group compared to those having a placebo drink, with the most pronounced effect seen on the specific symptom of ‘trouble concentrating’.
Can I pear-binge after drinking to cure my hangover?
NO. The effect was only demonstrated if pears were consumed before alcohol consumption. There is no evidence that you can consume pears after drinking and avoid a hangover.
And remember, the very best way to not get a hangover is to not drink in the first place.
Manny also warns this is only a preliminary scoping study, with the results yet to be finalised. Ultimately, her team hope to deliver a comprehensive review of the scientific literature on pears, pear components and relevant health measures. We’ll be sure to keep you posted.
