Essential Foods to Avoid If You Have Arthritis – What Science Says

Did you know certain foods can secretly be fueling your arthritis symptoms? Yep, that “harmless” soda or cheesy snack might be the reason your joints are screaming. If you’re living with arthritis—whether osteoarthritis, rheumatoid arthritis, or another type—your plate can play a massive role in how you feel day to day.

According to the Centers for Disease Control and Prevention (CDC), over 58.5 million adults in the U.S. are diagnosed with arthritis, and that number is growing every year. Many of those living with the condition report higher pain levels, limited mobility, and reduced quality of life.

18 Essential Foods to Avoid If You Have Arthritis

1. Processed and Red Meats

Why Avoid It: Red and processed meats (like bacon, sausages, and beef) are rich in saturated fats and advanced glycation end-products (AGEs)—both known to trigger inflammation.

Studies Say: A study published in Arthritis & Rheumatology linked high red meat consumption with increased inflammation and higher arthritis pain scores.

Examples to Avoid:

• Hot dogs
• Pepperoni
• Deli meats
• Beef burgers

Swap With:
Lean proteins like chicken breast, tofu, beans, and wild-caught fish (rich in omega-3s).

2. Refined Carbohydrates

Why Avoid It: White bread, pasta, and pastries spike blood sugar, which increases inflammation.

Scientific Backing: High-glycemic index foods worsen systemic inflammation, according to a study in the Journal of Nutrition (2017).

Avoid These:

• White rice
• White bread
• Pancakes
• Pizza crust (white flour)

Better Choices:

• Whole grain breads
• Quinoa
• Brown rice
• Oatmeal

3. Sugar and Sugary Beverages

Why Avoid It: Sugar increases levels of cytokines, which are inflammatory messengers in the body.

One Soda = One Flare-Up: Women who drank just one sugary soda daily had a 63% higher risk of developing RA, according to Harvard’s Nurses’ Health Study.

High-Risk Items:

• Soda
• Sweet tea
• Energy drinks
• Candy
• Ice cream

What to Drink Instead:

• Green tea
• Lemon water
• Turmeric lattes

4. Fried and Deep-Fried Foods

Why Avoid It: Cooking at high temperatures creates AGEs (advanced glycation end-products), which promote inflammation.

Think Twice About:

• French fries
• Fried chicken
• Onion rings
• Fried fish

Better Option:

• Air-fried or baked alternatives using olive oil or avocado oil

5. Dairy Products (in sensitive individuals)

Why Avoid It: Some people with arthritis are sensitive to casein, a protein in milk, which may trigger inflammation.

According to the Physicians Committee for Responsible Medicine, cutting out dairy improved symptoms in nearly 50% of participants with joint pain.

Dairy to Limit:

• Cheese
• Milk
• Cream
• Yogurt (unless it’s plant-based)

Try These Instead:

• Almond milk
• Oat milk yogurt
• Nutritional yeast for cheesy flavor

6. Gluten (for some arthritis types)

Why Avoid It: For individuals with celiac disease, non-celiac gluten sensitivity, or autoimmune arthritis, gluten can worsen joint inflammation.

Common Gluten Sources:

• Pasta
• Breads
• Crackers
• Cereals

Gluten-Free Options:

• Buckwheat
• Amaranth
• Gluten-free oats
• Chickpea flour

7. Excessive Alcohol

Why Avoid It: Alcohol can increase uric acid, leading to gout attacks, a painful arthritis type.

CDC Warning: Alcohol abuse is linked to joint degeneration, especially when mixed with NSAIDs (arthritis meds).

High-Risk Drinks:

• Beer (especially rich in purines)
• Sweet cocktails
• Wine (in excess)

Limit To:

• 1 drink/day for women, 2 drinks/day for men — or skip altogether

8. Salt (Sodium)

Why Avoid It: High salt intake leads to water retention, joint swelling, and blood pressure spikes.

FDA Guidelines: Keep sodium under 2,300 mg per day

Hidden Salt Bombs:

• Frozen meals
• Canned soups
• Instant noodles
• Potato chips

Healthier Swaps:

• Herbs & spices like turmeric, garlic, and rosemary

9. Vegetable Oils High in Omega-6 Fatty Acids

Why Avoid It: Omega-6 fats, found in many vegetable oils, can promote inflammation when consumed excessively.

Examples Include:

• Corn oil
• Soybean oil
• Sunflower oil

Better Choice:

• Extra virgin olive oil (anti-inflammatory)
• Avocado oil

10. Artificial Sweeteners (Aspartame, Sucralose)

Why Avoid It: Can trigger inflammation in some autoimmune arthritis patients.

According to a 2020 study in Frontiers in Immunology, artificial sweeteners altered gut bacteria and worsened immune responses in rheumatoid arthritis.

Found In:

• Diet sodas
• Sugar-free gum
• Light yogurt

Natural Sweetener Alternatives:

• Stevia
• Raw honey
• Monk fruit

11. MSG (Monosodium Glutamate)

Why Avoid It: MSG may increase inflammation in sensitive individuals.

Common in:

• Chinese takeout
• Frozen meals
• Flavored snacks
• Instant soups

12. Nightshade Vegetables (in certain people)

Why Avoid It: Tomatoes, peppers, potatoes, and eggplant contain solanine, which may cause joint pain in some arthritis sufferers.

There’s no solid scientific evidence against nightshades, but an elimination trial could help.

13. Margarine and Shortening

Why Avoid It: Contains trans fats, which are inflammatory and banned in many countries.

Hidden Sources:

• Packaged cookies
• Microwave popcorn
• Baked pies

14. Refined Grains

Why Avoid It: Lacks fiber and nutrients, spikes blood sugar.

Skip:

Why Avoid It: Caffeine overload may trigger inflammation in RA patients.

Stick To:

• 1–2 cups a day
• Add turmeric or cinnamon instead of creamers

16. Processed Cheese

Why Avoid It: High in saturated fat and additives.

Examples:

• American cheese slices
• Nacho cheese
• Cheese spreads

17. Store-Bought Salad Dressings
