In a 2006 research study, scientists sought to determine how long the peanut protein stays in a person’s saliva. The results reveal that it takes hours for the protein to be gone completely. The researchers advise people to brush their teeth after eating peanut products and wait at least a few hours before kissing someone with a peanut allergy.
Just as the person with a peanut allergy must avoid ingesting peanuts, the significant other might choose to abstain from eating peanuts when the couple is together.
Keep out of the nut house!!
