Broccoli is one of the most nutritious foods that grows in abundance in colder climates. Ironically, it’s also one of the most disliked vegetables. I guarantee, though, that with a bit of garlic and chilli it goes down a treat!

Cancer prevention

I’m always wary of claims that one individual ingredient or lifestyle change can cause cancer or prevent it, and the same is true here. However, broccoli does contain some chemical compounds that, in laboratory studies at least, seem to offer some prevention against cancerous changes in cells. The compounds indole-3-carbinole and sulphoraphane are the most widely studied. This doesn’t mean you can smoke 20 a day – it’s just an interesting insight into the powerful effects some foods may have.

Stomach ulcers

Some research suggests that sulphoraphane may help to kill the bacteria H. pylori, which is involved in stomach ulcers.
