Grapefruit can interact with some types of medication, heightening their potency and increasing the risk of unintentional overdose. We know that today thanks to Western University clinical pharmacologist David Bailey, who discovered the danger in 1991. There are more than 80 drugs on the market affected by grapefruit, including cholesterol medication and some anti-cancer and psychiatric treatments.

Bailey’s research prompted the use of medication labels advising patients not to take pills with grapefruit.
