Diet and Exercise Tips for Your AOSD Treatment Plan

Adult-onset Still’s disease (AOSD) is a rare type of arthritis that causes joint pain, swelling, and systemic inflammation. Healthcare providers typically treat AOSD with medications that target the immune system to control inflammation and prevent long-term joint damage.¹

While medications are the foundation of care, targeted lifestyle habits play a crucial supporting role. Building healthy diet and exercise routines into your daily life can help relieve symptoms, protect your mobility, and enhance your overall AOSD treatment plan.^2-4

Maintain a healthy weight

Each person’s experience with AOSD-related joint issues will be different. Some will have periods of flare-ups where symptoms get worse. Over time, this chronic (long-term) inflammation will take a toll on their body.²

One way to help lessen the impact of this damage is to avoid putting extra strain on the joints. When you are over a healthy weight, your joints take on added stress. This can cause additional problems alongside AOSD. Maintaining a healthy weight helps your joints function smoothly and is an important part of a good AOSD treatment plan.^2-4

What is an anti-inflammatory diet for AOSD?

Maintaining a healthy weight starts with eating a balanced diet. A well-balanced diet includes lots of fruits, vegetables, whole grains, and protein. There are even certain foods that can reduce inflammation. Eating a diet rich in these anti-inflammatory foods, and avoiding those that promote inflammation, may help ease symptoms.^5,6

Examples of foods or spices that can help fight inflammation include:^5,6

• Whole grains that are high in fiber
• Vegetables
• Fruits
• Beans
• Foods that contain monounsaturated fats (avocados, nuts, nut butters, and olive oil)
• Foods that contain polyunsaturated omega-3 fats (chia seeds, salmon, flaxseeds, and walnuts)
• Dark chocolate
• Tea and coffee
• Ginger
• Turmeric

Foods to avoid because they may promote inflammation include:^5,6

• Sugary drinks (juice, sweetened iced tea, or soda)
• Simple or refined carbohydrates (pasta, rice, white bread)
• Saturated fats or foods high in processed fats (butter, bacon, sausage, full-fat cream)
• Fried foods
• Large amounts of alcohol

Before beginning any new diet, talk to your doctor. They may want to add a nutritionist or registered dietitian to your healthcare team. Some clinics also have programs that can help you get fresh groceries or make meal plans.

How does exercise support AOSD treatment?

Exercise is essential for protecting your joint health and managing weight. Regular movement keeps joints flexible, builds supporting muscle, and slows disease progression. Strong muscles absorb impact, which directly reduces joint pain during daily tasks.^2-4

Aim for moderate physical activity a few times a week. "Moderate" activity varies based on your current physical ability. Focus on gentle, enjoyable activities such as:^2-4

• Dancing
• Swimming
• Walking with a friend
• Cleaning
• Gardening

Always check with your medical team before starting a new exercise program. They can advise you on safe intensity levels or refer you to physical or occupational therapists who specialize in AOSD treatment.

Should you take supplements for AOSD treatment?

You need a variety of vitamins and minerals for your body to function well. When you eat a balanced diet, you often get enough of these naturally. But in some cases, taking extra of (supplementing) certain things can be helpful.^3,5

For example, one possible side effect of steroids is weakened bones. If you are taking steroids for a long time, taking a vitamin D or calcium supplement may be helpful in protecting your bones.^3,5

However, not all supplements are good for you. In the United States, over-the-counter supplements are not regulated by the Food and Drug Administration (FDA) the way other drugs are. They may not contain exactly what they claim to. Also, some supplements, especially those with herbs in them, can interact with prescription drugs. Before starting any new vitamin or other supplement, talk with your doctor.⁷

How can diet and exercise help with fatigue and mood?

AOSD affects more than just physical joints—it also impacts energy levels. Chronic fatigue is one of the most challenging AOSD symptoms, often interfering with work and family life. Staying active and eating balanced meals are proven strategies for fatigue management, helping you sustain energy throughout the day.^2-4

Regular exercise and a balanced diet can also improve mood and reduce stress. This may be especially helpful when you are dealing with the emotional and mental toll of living with AOSD over a long period of time.^2,4
