The can of chickpeas I bought has the words Contains sulphites.

Should I worry? What are sulphites?

Scroll down here to start gathering responses to that question. Can you find any more?

One list I found in Planet Internet listed all the following numbers as sulphites: E220, E221, E222, E223, E224, E225, E226, E227, E228. The Wikipedia entry is different.

But most responses agree that sulphites are a preservative, and give a product a longer shelf life. They're also 'natural' in that they are part of your naturally occurring body.

After your research, what's your response? Are sulphites in food something I should worry about?
