Onion and leek consumption, garlic supplement use and the incidence of cancer
January 1994
TLDR Eating onions and garlic may have health benefits, but effects vary by type and preparation.
The document discussed the high consumption of Allium vegetables, particularly onions and garlic, in The Netherlands and other European countries, highlighting their historical use for medicinal purposes. It reviewed the organosulfur compounds in Alliums, which were believed to contribute to their health benefits, including antibacterial, fungicidal, and potential cardiovascular effects. However, the document noted that while in vitro studies showed some positive effects, such as antibacterial and fungicidal activity, these effects varied significantly depending on the type and preparation method of the Allium products. The document also mentioned that claims regarding cardiovascular benefits were only confirmed for fresh garlic at unrealistically high dosages.
