What is Joint Inflammation?

Joint inflammation, also known as arthritis, is a condition characterized by the inflammation and swelling of one or more joints in the body. 

It can cause pain, stiffness, and limited mobility, making it challenging for individuals to perform their daily activities comfortably.

There are several types of joint inflammation, with the most common being osteoarthritis and rheumatoid arthritis. 

Osteoarthritis (OA)s typically occurs due to wear and tear on the joints over time. It commonly affects older adults but can also develop due to injuries or repetitive stress on specific joints.

Rheumatoid arthritis, on the other hand, is an autoimmune disease where the body’s immune system mistakenly attacks its own tissues. This chronic condition primarily affects the lining of the joints (synovium), causing inflammation that can lead to joint damage if left untreated.

Other forms of joint inflammation include:

  • Gout (caused by an excess buildup of uric acid crystals in joints)
  • Psoriatic arthritis (associated with psoriasis skin condition)
  • Infectious arthritis (resulting from bacterial or viral infections)


Joint inflammation symptoms may vary depending on the type and severity of the condition. 

Common symptoms include 

  • Pain around affected joints
  • Swelling
  • Redness or warmth in the area
  • Stiffness upon waking up or after periods of rest
  • Decreased range of motion in joints
  • Fatigue
  • Fever in some cases


While there is no cure for most types of joint inflammation/arthritis currently available, various treatment options aim to manage symptoms effectively and improve the quality of life for those affected. 

These treatments often involve:

  • A combination of medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) or disease-modifying antirheumatic drugs (DMARDs)
  • Physical therapy exercises to strengthen muscles surrounding affected joints and improve flexibility/mobility
  • Lifestyle changes, including weight management through exercise and a healthy diet
  • Assistive devices like braces or splints for support
  • Heat/cold therapy
  • Alternative therapies such as acupuncture or herbal supplements
  • In severe cases, surgical interventions like joint replacement may be done.

Foods That Cause Inflammation in Joints

While there are various causes for joint inflammation, diet is crucial in either exacerbating or alleviating the symptoms.

Here are common foods that cause inflammation in joints:

1. Added sugar

Added sugar has been associated with various health issues, including joint inflammation. There are various explanations for this, but the main one is that sugar may facilitate insulin resistance which has been shown to trigger inflammatory responses within the body.

Insulin is a hormone that regulates blood sugar by carrying excess glucose in the blood into the cells to be used for energy. However, consuming high amounts of sugar leads to increased insulin release. Over time, this can lead to insulin resistance, where the body’s cells become less responsive to insulin’s effects.

Moreover, high-sugar foods are often calorie-dense but nutrient-poor, leading to weight gain and obesity. Excess body fat further contributes to inflammation as fat cells release pro-inflammatory chemicals called cytokines.

In a study on people with rheumatoid arthritis, various foods were consumed to check for their effects on their symptoms. At the end of the study, eating blueberries and spinach were shown to improve symptoms, while soda and desserts were shown to worsen the symptoms.

2. Refined grains and flour 

Refined grains are those that have undergone processing during which the outer layers of the grain, including bran and germ, are removed. 

This process strips away vital nutrients like fiber, vitamins, minerals, and antioxidants from the grain. What remains is a highly processed product that lacks essential components necessary for optimal health, including joint health.

Research has found that diets rich in refined grains can promote chronic low-grade inflammation throughout the body. These refined products contain less fiber than whole grains, which leads to imbalances in gut bacteria composition. Such imbalances result in increased production of pro-inflammatory compounds within the digestive system.

3. Artificial additives and preservatives

Artificial additives encompass a wide range of substances added to processed foods for various purposes, such as coloring agents (e.g., tartrazine), flavor enhancers (e.g., monosodium glutamate), emulsifiers (e.g., polysorbate 80), and stabilizers (e.g., sodium benzoate).

Unfortunately, some studies suggest that these additives may trigger inflammatory responses within the body.

On the other hand, preservatives are chemicals that prevent spoilage by inhibiting microbial growth in food products. Commonly used examples include:

  • Sulfites (often found in wines).
  • Nitrites/nitrates (used in cured meats).
  • BHA/BHT (butylated hydroxyanisole/butylated hydroxytoluene).
  • Propyl gallate

While they effectively extend shelf life, there is growing concern about their potential negative impact on human health, such as the release of pro-inflammatory cytokines, leading to joint inflammation and subsequent pain.

4. Fried foods

Numerous studies have linked high consumption of fried foods to increased levels of systemic inflammation in the body.

These foods are typically cooked at high temperatures using unhealthy oils that contain trans fats or omega-6 fatty acids, which can promote inflammatory responses within our cells.

Trans fats are artificially created through a process called hydrogenation that turns liquid oils into solid fats for better shelf life and taste enhancement. 

These fats increase bad cholesterol (LDL) and promote chronic low-grade inflammation throughout the body.

Similarly, omega-6 fatty acids are found abundantly in vegetable oils commonly used for frying. While they are essential for our health in moderate quantities when balanced with omega-3 fatty acids, an excessive intake of omega-6s can increase the release of pro-inflammatory responses within our bodies.

5. High sodium intake

Scientific studies have linked high sodium intake with increased markers of systemic inflammation—elevated C-reactive protein (CRP) levels—which are associated with numerous diseases, including rheumatoid arthritis and osteoarthritis.

In fact, a 2015 study on 18,555 people found that too much sodium increased the risk of developing rheumatoid arthritis.

Furthermore, excess sodium can stimulate certain immune cells that promote inflammation, leading to joint damage and pain.

In a lab study, mice on a high-sodium diet developed a more severe form of arthritis than those fed less salt.

Some high-sodium foods to cut from your diet include canned soup (and most canned foods in general), processed meats, some cheeses, pizza, and anything else that tastes too salty.

6. Red meat

Research studies have suggested that consuming large quantities of red meat can trigger an inflammatory response within the body. This is primarily attributed to two main factors: saturated fats and advanced glycation end products (AGEs).

  • Saturated Fats: Red meats tend to be high in saturated fats, which are known to promote inflammation within the body when consumed excessively. These fats stimulate the production of pro-inflammatory chemicals called cytokines that can aggravate joint pain and swelling.
  • Advanced Glycation End Products (AGEs): Cooking methods such as grilling or frying at high temperatures can lead to the formation of AGEs in red meat. These compounds have been associated with increased oxidative stress and inflammation throughout the body. Other foods that are high in AGEs include fries, margarine, mayonnaise, and American cheese.

7. Gluten-containing grains

Gluten refers to a group of proteins found in wheat, barley, rye, and other related grains. It provides elasticity to dough and helps maintain its shape.

Recent studies have suggested a link between certain inflammatory conditions, such as rheumatoid arthritis (RA), and increased susceptibility to experiencing joint inflammation after consuming gluten-containing grains. 

Although the exact mechanism is yet to be fully understood, it is believed that gluten proteins could trigger an immune response in susceptible individuals, leading to systemic inflammation and joint-related symptoms.

Apart from gluten, other components present in grains might also contribute to joint inflammation. For instance, lectins found abundantly in grains have been associated with digestive issues and joint pain in some individuals.

8. Alcohol

When consumed regularly or in large quantities, alcohol disrupts the balance between pro-inflammatory and anti-inflammatory substances in our system. Consequently, chronic inflammation arises within joints as well as other tissues throughout our bodies.

Additionally, alcohol inhibits nutrient absorption in the digestive tract by damaging cells responsible for absorbing essential vitamins and minerals such as calcium and vitamin D, both crucial for maintaining strong bones and healthy joints. Deficiencies in these nutrients can lead to weakened bone structure and increased vulnerability to joint problems.

Another way that excessive drinking affects joint health is by raising uric acid levels in the blood — a primary contributor to gout flare-ups. Gout causes sudden episodes of severe pain and swelling, primarily affecting smaller joints such as those found in toes or fingers.

Finally, alcohol acts as a diuretic, which means it promotes water loss through urine. This can lead to dehydration if not compensated with adequate water intake. 

Dehydration can cause joint tissues to become less elastic, increasing friction and subsequent inflammation.

9. Dairy Products

Dairy products contain a protein called casein, which can trigger an inflammatory response in the body, especially in sensitive individuals.

In addition, dairy products are often high in saturated fat, which can also contribute to inflammation. 

If you suspect that dairy products may be causing your joint inflammation, you may want to try eliminating them from your diet to see if your symptoms improve.

10. Vegetable Oils

Industrial seed oils like soybean, corn, and sunflower oil are commonly used in processed foods. 

These oils contain high levels of omega-6 fatty acids, which can promote inflammation if consumed excessively compared to omega-3 fatty acids found in fish or flaxseed oil. 

Maintaining a balance between the two is crucial for joint health and overall well-being.

What To Eat Instead?

While eliminating the above foods is essential for fighting joint inflammation, below are some inflammation-fighting foods to add to your diet.

1. Omega-3 fatty acids:
