Korean Pear

Don’t confuse this fruit with a normal pear. The Korean (or Asian) pear is large, round, crisp and very juicy. In addition to its tastiness, this fruit has been shown to have some very powerful effects. Traditionally, the Korean pear has long been used as a remedy for a hangover. 

The effect has been seen from consuming at least 220ml of Korean pear juice prior to the consumption of alcohol. 

The CSIRO review has uncovered both animal and human studies trying to understand why. It appears that phenolic acids in Korean pears act on the livers 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 hangover symptoms. 

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’.
