Mayonnaise and gout: what to know

Gout develops when urate crystals trigger inflammation in a joint. Mayonnaise itself is not a major purine source because it is mainly made from oil and egg, but it can add substantial fat and energy to a meal. Flavoured or prepared versions may also contain salt, sugar, or other ingredients. A small amount used with a balanced meal is different from using it as a main source of calories. Your wider pattern matters, including alcohol, sweetened drinks, hydration, body weight, and kidney health. Gout can affect the big toe, ankle, knee, or another joint, with sudden pain, warmth, swelling, and tenderness.

Check the ingredient list, choose a portion that suits your meal, and compare regular, light, and flavoured products for added sugar and salt. Use mayonnaise with vegetables, whole grains, or a protein choice that fits your clinician’s advice rather than letting it replace a varied meal. Keep a note of foods and drinks around a flare if you are trying to identify personal triggers. Do not stop prescribed urate-lowering or flare medicine because a condiment seems acceptable. A dietitian or clinician can help tailor advice if you also have Chronic Kidney Disease or are managing Obesity.

Seek prompt medical advice for a hot, swollen joint with severe or new pain, especially if you have fever, feel unwell, or cannot bear weight. These features need assessment because several conditions can cause an acutely inflamed joint. Arrange a review when attacks recur, symptoms do not settle, or swelling persists between flares. Joint Pain, Joint Swelling, Ankle Swelling, Knee Pain, or Knee Swelling can help you describe what you are experiencing, but they do not establish the cause.

Ask whether your current urate plan is controlling flares, whether kidney function changes your dietary advice, and which foods or drinks are most relevant to your own pattern. Ask what to do at the first sign of a flare and whether persistent knee or ankle swelling needs examination.
