Living with arthritis involves managing inflammation and pain, and diet plays a significant role in this. Certain foods can exacerbate inflammation, worsening arthritis symptoms, while others can help reduce it. Understanding what foods to avoid is a crucial step in managing arthritis effectively.
1. Red Meat
Red meat, including beef, pork, and lamb, is generally higher in saturated fat compared to white meats and plant-based protein sources. Numerous studies have linked red meat consumption to increased levels of inflammation in the body. This inflammatory response can lead to aggravated joint swelling and intensified arthritis symptoms.
Research suggests that substituting red meat with leaner options can be beneficial. One study indicated that replacing red meat with chicken, fish, legumes, or nuts was associated with lower levels of inflammatory biomarkers in the blood. Reducing red meat intake might contribute to managing arthritis symptoms more effectively.
2. High-Fat Dairy Products
Dairy products, particularly those high in fat, can potentially worsen arthritis symptoms in some individuals. The impact of dairy seems to be closely related to the fat and sugar content of specific dairy items.
For those managing arthritis, it’s generally advisable to limit or avoid full-fat dairy and products with added sugars. These include items like:
- Cheese, especially hard and processed cheeses
- Whole milk
- Ice cream and high-fat frozen desserts
- Sour cream
- Butter
Studies have indicated a connection between diets high in saturated fat and increased inflammatory responses within the body. However, it’s worth noting that individual reactions to dairy can vary. Some people may be more sensitive than others. If you suspect dairy might be contributing to your arthritis symptoms, consider an elimination diet under the guidance of a healthcare professional or registered dietitian to assess your tolerance.
It’s important to note that not all dairy is detrimental. Some dairy products, like yogurt and kefir, are rich in probiotics – beneficial bacteria that can support gut health. A healthy gut microbiome is increasingly recognized for its role in reducing inflammation throughout the body. If you tolerate dairy, opting for low-fat, unsweetened yogurt or kefir might be a better choice than high-fat alternatives.
3. Omega-6 Fatty Acids
Omega-6 fatty acids are essential polyunsaturated fats that the body cannot produce on its own, meaning they must be obtained through diet. While omega-6s are necessary for various bodily functions, including brain function and bone health, excessive consumption can promote inflammation, potentially worsening arthritis symptoms.
Common sources of omega-6 fatty acids include various vegetable oils and certain meats. Examples of these oils are:
- Soybean oil
- Corn oil
- Safflower oil
- Sunflower oil
- Canola oil
It’s not necessary to eliminate these foods entirely as they do offer nutritional benefits. The key is to maintain a healthy balance between omega-6 and omega-3 fatty acid intake. Omega-3 fatty acids, found in fatty fish and flaxseeds, have anti-inflammatory properties.
Research indicates that the typical American diet often contains a significantly higher ratio of omega-6 to omega-3 fatty acids than is considered optimal. To address this imbalance, it’s recommended to moderate your intake of omega-6 rich foods and increase your consumption of omega-3 rich foods. Excellent sources of omega-3s include salmon, mackerel, sardines, anchovies, and other fatty fish. When cooking, consider using olive oil, which is primarily composed of monounsaturated fats and is considered a healthier option compared to oils high in omega-6s.
4. High Salt Foods
While sodium from salt is essential for various bodily functions, excessive salt intake, which is common in many diets, can be problematic, especially for individuals with arthritis. Research has linked high salt consumption to increased inflammation and a heightened risk of developing rheumatoid arthritis.

Salt is frequently used as a preservative in processed and packaged foods. Foods that are typically high in sodium include:
- Processed meats like deli meats, bacon, sausage, and salami
- Fast food items such as pizza, burgers, French fries, tacos, and burritos
- Savory snacks like crackers, chips, and popcorn
- Pre-made rice and pasta mixes
To reduce sodium intake, prioritize fresh, whole foods and carefully read food labels. Opt for products labeled “low sodium” or “no salt added”. Instead of relying on salt for flavor, experiment with herbs, spices, and salt-free seasoning blends to enhance the taste of your meals. The American Heart Association recommends limiting sodium intake to no more than 2,300 milligrams per day for general health, and even less for individuals with certain health conditions.
5. High-Sugar Foods and Beverages
Foods and beverages high in added sugars are widespread in modern diets and can contribute to inflammation. Common sources of added sugars include:
- Candy and sweets
- Desserts such as cakes, cookies, and pastries
- Baked goods
- Ice cream and other sugary frozen treats
- Fruits canned in syrup
- Processed snacks and sugary cereals
- Condiments like ketchup, barbecue sauce, and many salad dressings
Sugar-sweetened beverages are also significant contributors to added sugar intake:
- Soda and sugary drinks
- Fruit juices (even 100% fruit juice can be high in natural sugars, limit portion sizes)
- Sweetened tea and coffee drinks
- Energy drinks and sports drinks
Added sugars provide minimal nutritional value and are often referred to as “empty calories.” Furthermore, they can promote inflammation in the body. Aim to limit added sugar intake significantly. The American Heart Association recommends limiting added sugar to no more than 6 teaspoons (25 grams) per day for women and 9 teaspoons (36 grams) per day for men. To put this in perspective, a 12-ounce can of soda can contain 39 grams of sugar or more.
To reduce sugar intake, choose fresh fruit over processed snacks, opt for fruit canned in water or its own juice instead of syrup, and select unsweetened versions of your favorite beverages. Flavor water or tea with natural additions like lemon or lime slices instead of sugar. Read food labels carefully to identify added sugars, often listed as sucrose, fructose, corn syrup, and other words ending in “-ose”.
6. Fried Foods
Fried foods are frequently cooked in oils high in saturated fat and omega-6 fatty acids, both of which are linked to increased inflammation and potential worsening of arthritis symptoms.
Beyond the oils used for frying, fried foods often contain other pro-inflammatory ingredients. Breading, for example, can be made with refined carbohydrates, and fried foods are often heavily salted. Some may even contain added sugars in coatings or seasonings.
Preparing meals at home more often gives you greater control over ingredients and cooking methods. Instead of frying, explore healthier cooking techniques like baking, grilling, roasting, steaming, or air frying. Air frying can provide a crispy texture similar to frying but with significantly less oil.
7. Processed Foods
Highly processed foods are a significant part of many modern diets but can negatively impact arthritis. These foods, including frozen meals, lunch meats, many baked goods, fast food, and packaged snacks, are typically formulated with refined grains, added sugars, excessive salt, and unhealthy fats to extend shelf life and enhance flavor. These components can all contribute to increased inflammation in the body.
A diet high in processed foods is also associated with increased risks of obesity and insulin resistance. These conditions can indirectly worsen arthritis symptoms and overall health. To minimize the impact of processed foods on arthritis, focus on a diet rich in whole, unprocessed foods like fruits, vegetables, lean proteins, and whole grains.
8. Alcohol
The relationship between alcohol and arthritis is complex and varies depending on the type of alcohol and the type of arthritis. Some alcoholic beverages, like red wine, contain antioxidants, such as resveratrol, which may have anti-inflammatory properties. Moderate red wine consumption (around 5 ounces per day) has been linked to potential benefits for joint health in some studies.
However, for certain types of arthritis, particularly gout, alcohol can be a trigger for flares. Studies have associated alcohol consumption, across all types of alcoholic beverages, with an increased risk of developing gout and experiencing more frequent gout flare-ups.
For individuals with inflammatory forms of arthritis other than gout, moderate alcohol consumption may not be detrimental, and in the case of red wine, might even offer some anti-inflammatory benefits. However, excessive alcohol intake is generally detrimental to health and can interfere with certain arthritis medications. It’s best to discuss alcohol consumption with your doctor, considering your specific type of arthritis, medications, and overall health status.
9. Refined Carbohydrates
Refined carbohydrates are carbohydrates that have been processed to remove bran and germ, resulting in a less nutritious product. Common examples include white flour and white rice. This processing strips away most of the fiber, vitamins, and minerals, leaving behind primarily simple carbohydrates.
These simple carbohydrates are rapidly digested and absorbed, leading to quick spikes in blood sugar levels. These blood sugar spikes can trigger inflammatory responses in the body. Therefore, refined carbohydrates can contribute to inflammation and potentially worsen arthritis symptoms.
To mitigate these effects, prioritize complex carbohydrates over refined ones. Complex carbohydrates, such as brown rice, quinoa, oats, and whole-grain breads and cereals, are digested more slowly, leading to a more gradual release of sugar into the bloodstream. They also retain their fiber and nutrient content, offering additional health benefits. When choosing grain products, opt for whole-grain versions and check labels to ensure they are low in added sugars.
10. Gluten
Gluten is a protein found in grains like wheat, barley, and rye. While not everyone is sensitive to gluten, some research suggests that a gluten-free diet may benefit individuals with rheumatoid arthritis by reducing inflammation.
Studies have also observed a higher prevalence of celiac disease among people with rheumatoid arthritis. Celiac disease is an autoimmune disorder where gluten triggers an inflammatory response in the small intestine and other parts of the body.
If you have rheumatoid arthritis or suspect you might be sensitive to gluten, it could be worthwhile to try a gluten-free diet under the guidance of a healthcare professional or registered dietitian. This involves eliminating gluten-containing foods from your diet to see if your arthritis symptoms improve. It’s important to ensure a balanced and nutritious diet while following a gluten-free approach.
11. Purines
Purines are naturally occurring substances found in the body and in certain foods. When the body breaks down purines, it produces uric acid. In individuals susceptible to gout, excessive uric acid can lead to elevated levels in the blood, causing uric acid crystals to form in the joints. These crystals trigger intense pain and inflammation characteristic of gout flares.
Foods and drinks high in purines include:
- Alcoholic beverages, especially beer and liquor
- Certain types of fish, seafood, and shellfish, such as anchovies, sardines, herring, mussels, codfish, scallops, trout, and haddock
- Meats, including bacon, turkey, veal, venison, and organ meats like liver
If you have gout or are at risk of developing it, limiting high-purine foods and beverages is often recommended to help manage uric acid levels and prevent gout flares.
12. Advanced Glycation End Products (AGEs)
Advanced glycation end products (AGEs) are compounds that form through reactions between sugars and proteins or fats. They are naturally present in uncooked animal foods and can also be produced during certain cooking methods, particularly those involving high temperatures and low moisture, such as frying, roasting, grilling, and broiling.
High levels of AGEs in the body contribute to inflammation and oxidative stress, which are implicated in the development and progression of arthritis and various other health conditions.
Foods high in AGEs include:
- High-fat animal proteins cooked at high temperatures, such as fried, roasted, grilled, or broiled bacon, steak, chicken, salmon, and hot dogs
- French fries
- Aged and hard cheeses
- Crackers, chips, and cookies made with dry heat processing
- Butter, margarine, and mayonnaise
To reduce AGE intake, prioritize cooking methods that use lower temperatures and higher moisture, such as steaming, boiling, poaching, or stewing. Emphasize fresh, unprocessed foods like fruits, vegetables, beans, and fish in your diet, as these are naturally low in AGEs and often rich in antioxidants that can help counter oxidative stress.
13. Coffee
The impact of coffee on arthritis is not fully clear and research findings are somewhat mixed. Coffee contains antioxidants called polyphenols, which may have anti-inflammatory effects and potentially benefit certain forms of arthritis, such as gout. Some studies suggest coffee consumption might be associated with a lower risk of gout.
However, other research indicates a possible link between coffee consumption and an increased risk of developing certain types of arthritis, such as rheumatoid arthritis and osteoarthritis. These findings are not conclusive, and more research is needed to fully understand the relationship.
Given the uncertainty, it’s generally prudent to consume coffee in moderation, especially if you have arthritis. Limiting intake to no more than 1 or 2 cups per day is a reasonable guideline. It’s also advisable to avoid adding excessive amounts of cream, whipped cream, sugar, and syrups to your coffee, as these additions can negate potential benefits and contribute to other health concerns.
While this article focuses on foods to avoid, it’s important to remember that a balanced diet rich in anti-inflammatory foods is also crucial for managing arthritis. These include fatty fish, nuts, seeds, fruits, vegetables, and whole grains. Alongside dietary changes, other lifestyle modifications like weight management and regular physical activity are essential components of a comprehensive arthritis management plan.
