Raw Onions: Potential Health Risks and Side Effects

Raw onions, while nutritious, can cause problems for some people.

They might trigger headaches in those prone to migraines due to a substance called tyramine.

Eating raw onions can also lead to bad breath because of sulfur compounds.

For some, raw onions cause tummy troubles like bloating and gas because of a carbohydrate called fructans.

People can also have allergic reactions, which could cause serious problems, while people with acid reflux may see their symptoms worsen.

Cooking onions can often lessen these effects.
