A message doing rounds on social media claims that onions become poisonous when left cut overnight. Because of this reason, one should not consume onions left outside. We investigated and found that the viral post is false.
The viral post on social media claims that it is dangerous to leave a cut onion and try to consume it the following day. The post reads, “Please remember it is dangerous to cut an onion and try to use it to cook the next day. It becomes highly poisonous for even a single night and creates toxic bacteria which may cause adverse stomach infections because of excess bile secretions and even food poisoning“
We started investigation and searched appropriate keywords on Google. We found that the message is plaguing the internet since ages.
We further searched and found a report on the official website of National Onion Association. According to National Onion Association, the claim is not scientifically proven.
In fact, the National Onion Association has also issued a letter to consumers about cut onion claims. The letter states that information circulated online is false.
We even asked a few nutrition experts on the claim.
According to Dr. Medhavi Gautam, Chief Dietitian at Santokba Durlabhji Memorial Hospital, Jaipur, this claim is false and onions cannot protect against the flu.
According to Kajal Gupta, Dietitian and a part of THIP’s Review Team, “Onions have a lot of anti-bacterial properties and have multiple health benefits. They do not attract bacteria, store it and then harm your body anyone. This type of claims are absolutely false”
