Intake of Lactobacillus rhamnosus GG (LGG) fermented milk before drinking alcohol reduces acetaldehyde levels and duration of flushing in drinkers with wild-type and heterozygous mutant ALDH2: a randomized, blinded crossover controlled trial

Alcohol consumption leads to acetaldehyde accumulation which is carcinogenic. Drinking LGG fermented milk before alcohol intake reduces blood and salivary acetaldehyde levels especially in people with mutant aldehyde dehydrogenase 2 gene ( ALDH2 ).
