Lupus is a chronic autoimmune disease that can affect various parts of the body, causing inflammation and a range of symptoms. While there is no cure for lupus, managing the condition through medication and lifestyle adjustments, including diet, can significantly improve symptoms and overall quality of life. This article explores the benefits of a lupus diet plan, providing guidance on foods to include and avoid, and addresses common misconceptions about diet and lupus.
Understanding Lupus and the Importance of Nutrition
Lupus is an inflammatory disease where the immune system attacks healthy tissues and organs. Although no specific food can cause or cure lupus, a well-balanced diet is crucial for managing symptoms, reducing inflammation, maintaining strong bones and muscles, combating medication side effects, achieving a healthy weight, and reducing the risk of heart disease.
General Nutritional Guidelines for Lupus
Individuals with lupus should generally follow a diet that is:
- Low in fat, cholesterol, and sodium
- Low in refined sugars
- High in fiber
It is also important to maintain a well-balanced diet with a variety of foods to ensure adequate intake of essential nutrients.
Foods to Include in a Lupus Diet Plan
A lupus diet plan should focus on incorporating foods that offer anti-inflammatory properties, support bone health, and promote overall well-being.

Fruits and Vegetables
Fruits and vegetables are rich in antioxidants and fiber, providing essential vitamins and minerals. They are a great source of Vitamin A and Vitamin C. Examples include leafy greens (spinach, kale), berries, and colorful vegetables.
Healthy Fats and Oils
Unsaturated fats, such as polyunsaturated and monounsaturated fats, are healthier alternatives to saturated fats. These fats have anti-inflammatory properties and are a good source of Vitamin E. Foods containing unsaturated fats include nuts, seeds, avocados, olive oil, soybean oil, and canola oil.
Low-Calorie Foods
Choosing low-calorie options and avoiding excessive amounts of dressings, oils, butter, and sugar can help manage weight and reduce inflammation.
High Calcium and Vitamin D Intake
Calcium and Vitamin D are essential for maintaining strong bones, which is particularly important for people with lupus due to the increased risk of osteoporosis from certain medications. Foods high in calcium and Vitamin D include:
- Low-fat or fat-free dairy products (milk, yogurt, cheese)
- Lactose-free milk alternatives (soy milk, almond milk)
- Fortified cereals
- Dark green vegetables (broccoli, kale)
- Wild salmon (with bones)
- Sardines (with bones)
- Mushrooms (shiitake)
Meat, Fish, and Poultry
These foods provide zinc and B vitamins and are a good source of Omega-3 fatty acids and protein, which are important for maintaining muscle mass. Fatty fish like salmon, mackerel, tuna, halibut, and trout are particularly beneficial due to their high Omega-3 content.

Beans, Nuts, and Seeds
Beans, nuts, and seeds are good sources of vitamin E, selenium, protein, and fiber. When purchasing these items, look for unsalted and low-sodium options. Flaxseed, in particular, may offer protection against lupus nephritis (kidney disease associated with lupus).
Foods to Avoid or Limit in a Lupus Diet Plan
Certain foods may exacerbate inflammation or interfere with lupus medications, so it's important to limit or avoid them.
Saturated Fats
Saturated fats can increase inflammation and raise cholesterol levels. Sources of saturated fats include:
- High-fat dairy products (whole milk, cream, cheeses, butter, ice cream)
- Fried foods
- Commercial baked goods
- Creamed soups and sauces
- Red meat
- Animal fat
- Processed meat products
Processed Foods
Processed foods often contain additives, unhealthy fats, and high levels of sodium, which can contribute to inflammation and other health problems. Examples include:
- Canned soups
- Frozen meals
- Processed meats (deli meats, hot dogs, sausages)
- Snacks (potato chips, crackers, cookies)
Sugary Foods
Excessive sugar intake can lead to weight gain, high cholesterol, and the release of inflammatory chemicals called cytokines. Limit consumption of candy, cakes, cookies, and foods with hidden sugars like pasta sauce and ketchup.

Alfalfa Sprouts
Alfalfa sprouts and seeds contain an amino acid called L-canavanine, which may trigger inflammation, fatigue, and muscle aches in some individuals with lupus. It's advisable to avoid alfalfa sprouts and supplements.
Alcohol
Alcohol can interact with some lupus medications, including blood thinners, and should be consumed in moderation, if at all.
Nightshade Vegetables
While research is inconclusive, some individuals may find that nightshade vegetables (tomatoes, potatoes, eggplant, peppers) worsen their symptoms. Monitoring your body's response to these vegetables and adjusting your diet accordingly is recommended.
Addressing Specific Concerns and Medication Side Effects
Lupus and its treatments can lead to various complications and side effects that may require specific dietary adjustments.
Countering Weakening Bones
Corticosteroids, a common lupus treatment, can increase the risk of osteoporosis. Eating foods high in calcium and vitamin D is important for bone health. If dietary intake is insufficient, a doctor may recommend calcium and vitamin D supplements.
Countering Folic Acid Loss
Methotrexate, a lupus drug, can interfere with folic acid processing. Increasing folic acid intake through leafy green vegetables, fruits, fortified breads and cereals, or a folic acid supplement (as advised by a doctor) may be necessary.
Lowering Blood Pressure
Some lupus medications, like corticosteroids, can raise blood pressure. A low-salt diet that includes fresh fruits and vegetables can help reduce fluid retention and lower blood pressure.
Managing Weight Loss or Gain
Lupus can cause unhealthy weight loss due to poor appetite or medication side effects, while weight gain can result from inactivity or corticosteroid use. Consulting a doctor or registered dietitian can help develop a personalized plan to manage weight through a low-fat diet and exercise.
Countering Nausea and Upset Stomach
To alleviate nausea and upset stomach, avoid greasy, spicy, and acidic foods. Eating small, frequent meals of easily digestible foods like dry cereals, breads, and crackers may help. Taking medications like corticosteroids or NSAIDs with meals can also reduce stomach upset.
The Importance of a Heart-Healthy Diet
People with lupus have a higher risk of heart disease, making a heart-healthy diet an essential part of their treatment plan. This includes a low-fat, low-sodium diet, regular exercise, and foods rich in omega-3 fatty acids.
Supplements and Lupus
While a balanced diet should be the primary focus, some supplements may be beneficial for people with lupus. However, it's crucial to consult with a doctor before starting any new supplements, as they can interact with lupus medications.
Vitamin D
Vitamin D deficiency is common in people with lupus, and supplementation may have positive effects on bone health, immunity, and cardiovascular health.
Omega-3 Fatty Acids
Omega-3 fatty acids from fish or fish oils may improve risk factors for heart disease, such as high triglycerides and blood pressure.
Flaxseed
Some studies suggest that flaxseed may protect against lupus nephritis, but more research is needed to confirm these findings.
DHEA (Dehydroepiandrosterone)
Some studies indicate that DHEA may help reduce flares and disease activity, as well as decrease the need for steroids.
Separating Fact from Fiction: Common Beliefs About Diet and Lupus
It's important to dispel common misconceptions about diet and lupus to avoid unnecessary restrictions and confusion.
- Fiction: Certain foods cause lupus flares. Unless a particular food seems to trigger a flare for you, there is no reason to avoid any specific foods.
- Fiction: Fish oil cures joint inflammation. While omega-3 fatty acids have anti-inflammatory properties, they are not a cure for joint inflammation.
- Fiction: People with lupus should follow an anti-inflammatory diet. While a healthy, balanced diet rich in fruits, vegetables, and low-fat proteins is recommended, there is no specific anti-inflammatory diet for lupus.
- Fiction: People with lupus should not exercise. Exercise is an important part of health and weight maintenance for people with lupus.
- Fiction: Acai berry is good for people with lupus. There is no evidence to suggest that acai berry is beneficial for lupus.
- Fiction: Dietary supplements help reduce lupus flares. There is little convincing evidence to support the use of any specific dietary supplement for reducing lupus flares.
- Fiction: Iron causes lupus flares and should be avoided in the diet. Iron is an important nutrient for the production of red blood cells and should not be restricted unless there is a specific reason to do so.
The Mediterranean Diet and Lupus
The Mediterranean diet, characterized by high amounts of vegetables, fruits, olive oil, whole grains, and beans, and moderate amounts of fish, chicken, low-fat dairy, and nuts, has been linked to lower levels of inflammation and chronic disease. This dietary pattern may be beneficial for people with lupus due to its anti-inflammatory properties and potential to reduce the risk of heart disease, diabetes, and obesity.
The Autoimmune Protocol (AIP) Diet
The autoimmune protocol (AIP) diet may help you figure out which foods to avoid. With this elimination diet, you cut out foods known to trigger inflammation and then gradually add them back in. If you experience a lupus flare, you may want to avoid that food going forward. But you should only start an AIP diet with the help and guidance of a registered dietitian.
Lifestyle Factors and Lupus
In addition to diet, other lifestyle factors, such as maintaining a healthy body weight, exercising, consuming alcohol in moderation, and not smoking, may also play a role in managing lupus symptoms and reducing the risk of complications.
Seeking Professional Guidance
It is essential for people with lupus to work with a healthcare team, including a doctor and a registered dietitian, to develop a personalized diet plan that meets their individual needs and addresses any specific concerns or medication side effects.
