Gout

inflamed big toe joint

Gout is a painful condition which affects the joints and it has characteristic flare-ups called gout attacks. It develops when uric acid crystals accumulate in the joints, causing chronic inflammation and irritation. During gout attacks, people experience intense joint pain and often also swelling and redness of the affected joints. Gout usually shows up in the big toe joints but can cause intense pain in other toe joints, ankles or knees, too.

High levels of uric acid in the body have also been linked to kidney and heart disease – particularly to sudden events, such as heart attack or stroke, heart failure and atrial fibrillation (irregular heartbeat) (Maloberti et al., 2021).

Your body produces uric acid when it breaks down purines — compounds found naturally in your body but also in many foods. The richest sources of purines by far are red meat and organ meats, such as liver or kidneys, and fish, such as anchovies, sardines, trout, tuna, mussels and scallops. Alcohol and drinks sweetened with fructose also contribute to higher levels of uric acid.

Gout has been known for millenia and usually only affected rich people who had diets high in animal foods and alcohol. Nowadays, however, it’s more and more common as people eat meat and fish on a daily basis. As one review neatly summarised, seafood, red meat, alcohol and fructose increase the risk, while soya and other pulses (peas, beans, lentils) and coffee lower the risk (Li et al., 2018). This highlighths that there’s no need to avoid pulses as was once recommended because of their purine content – they contain much less than meat, fish or shellfish and also offer a wide range of healthful nutrients.

A comprehensive review study focused on plant-based diets, uric acid and the risk of gout (Jakše et al., 2019). According to the results, plant-based diets do not put you at risk of gout even if you consume purine-containing pulses and vegetables or mock-meat products – they simply aren’t as high in purines as meat and fish. In fact, the study authors concluded that plant-based diets help to prevent gout and maintain healthy uric acid levels.
