A diverse grab-bag of foods can trigger gout flare-ups.

If you’re one of the nearly 200,000 Australians who experience symptoms of gout, you’re familiar with another four-letter word: pain.

“The classic presentation of gout is severe pain—usually in a single joint, and most commonly in the big toe,” says Dr Bernadette Siaton. (It’s not clear why the big toe is gout’s favourite target; it may have to do in part with the type of cartilage in the toe, research shows.)

Gout pain tends to come on very quickly, though it’s slow to depart. “You’re great one night, but the next day the pain is so severe you can barely walk or put on shoes,” Siaton says. “In some cases, it can last for days or even weeks.”

Gout is a form of arthritis, and it stems from the build-up of uric acid in the body, according to the National Institutes of Health. That build-up can lead to the formation of small uric acid “crystals” in your joints, which are the source of your pain.

Where does the uric acid come from? “Purines,” Siaton says. And what exactly are purines? “These are chemical compounds found in DNA,” she explains.

Your body breaks down these purines during normal cell metabolism, and also after you’ve eaten purine-rich foods, she says. If your body is unable to handle all the uric acid that results from the breakdown of purines, that's when gout can emerge.

Dr. Siaton says middle-aged men and post-menopausal women are most likely to develop gout, although it can strike at any age.

So which foods spell trouble for gout sufferers? Here are six to avoid.
