On the right side of the abdomen, there is a vestigial organ called the appendix that resembles a little finger. Even though it is a relic of an organ, it is a component of our digestive system. Appendicitis refers to the swelling of the appendix, a small pouch attached to the large intestine. While the exact cause is often unknown, certain foods are more likely to cause appendicitis due to their impact on digestion. In this write-up, we will discuss what food can cause appendicitis, symptoms and prevention. 

What Food Can Cause Appendicitis?

1. Popcorn

Popcorn kernels can be hard to digest and pass through the digestive tract. The skins and seeds of popcorn contain insoluble fibre that may get lodged in the appendix, causing an obstruction that leads to inflammation.

2. Nuts and Seeds

So, what food can cause appendicitis? Nuts, seeds, and nut butters are likely to cause appendicitis as they contain insoluble fiber, making them more likely to obstruct the appendix. They are also high in fat, which takes longer to digest. Examples include almonds, walnuts, peanuts, cashews, chia seeds, flax seeds, and sunflower seeds.

3. Dried Fruits

While healthy overall, dried fruits like raisins, cranberries, and apricots are dense in fiber and low in water content. This makes them more difficult to pass, allowing particles to get stuck in the appendix. They swell when rehydrated, further worsening obstruction.

4. Uncooked Veggies 

Raw vegetables like celery, carrots, bell peppers, cabbage, cauliflower, and broccoli are packed with insoluble fiber that is tough on digestion. Cooking softens fiber and makes vegetables easier to pass through the colon intact.  

5. Whole Grains

Next in our list of what food can cause appendicitis is whole grains. Diets high in whole grains like whole wheat, farro, barley, and brown rice provide loads of beneficial fibre. But these insoluble fibres may congest the appendix when overconsumed.

6. Red Meat

Studies reveal that diets high in red meat, especially processed and smoked varieties, increase appendicitis risk. They are harder to digest and may damage the appendix lining over time, enabling infection.

7. Refined Carbs

Foods made with white flour and added sugars like cookies, cakes, muffins, pastries, cereals, and white bread offer low fiber content. They can constipate, leading to obstruction from waste buildup in the appendix.

8. Fiber Supplements 

Ironically, fiber supplements containing concentrates, bran, powders, or psyllium husk taken in excess can obstruct the appendix. They greatly expand in water. You need to begin with low quantity. 

9. Dehydrated Foods

Dried or dehydrated foods with little moisture like beef jerky, dried fruit leathers, and low-sodium crackers. They absorb water which causes them to swell up. This becomes problematic when lodged in the appendix.  

10. Greasy Fast Food

Grease-laden fast food like french fries, chicken nuggets, burgers, and pizza deliver calories lacking in nutrients. High fat intake makes the appendix work harder during digestion, allowing obstructions to occur. Limit fried and heavily oiled foods.

11. Alcohol 

Alcohol irritates the digestive tract, potentially causing appendix inflammation over time. Beer, wine, and liquor contain compounds and congeners that are toxic to the appendix. Binge drinking may substantially raise appendicitis risk.

12. Soda and Carbonated Drinks

You must limit the intake of carbonated drinks while you are looking for what food can cause appendicitis. The carbonation and bubbles in soda, sparkling water, and energy drinks can get trapped in the appendix, increasing pressure and obstruction. The artificial flavours and sweeteners which are used in those drinks can be another reason for it. 

Symptoms of Appendicitis 

Being able to identify the key symptoms of appendicitis is important, as it requires emergency medical care. They are- 

  • Abdominal Pain

The most common initial symptom of appendicitis is pain around the navel or top of the abdomen. This discomfort often begins as mild cramping or bloating sensation. However, over time the pain travels and localises in the lower right side of the abdomen, becoming more sharp and severe. 

  • Gastrointestinal symptoms 

As appendicitis advances, other gastrointestinal symptoms may arise including loss of appetite, nausea, vomiting, constipation or diarrhea. Sufferers often experience abdominal bloating. Gas pain may also develop as obstruction of the appendix impairs the body’s ability to pass stool. 

  • High Fever 

Besides abdominal pain, fever of 99-102°F is another classic sign of appendicitis. This indicates the body’s inflammatory immune response. Chills, weakness, and fatigue are also common as the infection develops. 

  • Back Pain 

When the abdominal muscles tense to guard the inflamed appendix, they cause referred pain that can extend to the back or rectum. Pain can worsen with walking, coughing, or sudden movements that jostle the appendix.

How To Prevent Appendicitis?

Now that you know what food can cause appendicitis and the symptoms, you should also check out how to prevent it. 


  • Eat a high fiber diet. Fiber from fruits, vegetables, whole grains, beans, nuts and seeds helps prevent constipation and obstructions. Stay hydrated. 


  • Limit red meat intake. Diets high in processed meats are associated with increased appendicitis risk.


  • Avoid greasy, fatty foods. Foods high in saturated fat like pizza, burgers and fried items make the appendix work harder during digestion.


  • Reduce refined carbs. Refined grains and added sugars can promote constipation due to lack of fiber. 


  • Don’t overdo it on nuts, seeds, corn and popcorn. They contain insoluble fibers that may obstruct the appendix.


  • Cook vegetables to soften fiber. Raw veggies are harder to break down and fully digest. 


  • Cut back on alcohol, especially binge drinking episodes. Alcohol irritates the digestive tract.


  • Skip the sodas and carbonated drinks. Bubbly beverages can get trapped in the appendix.  


  • Include probiotic foods like yogurt and kefir. They promote healthy gut flora.


  • Maintain a healthy weight. Obesity appears to increase appendicitis risk. 


  • Don’t smoke. Smoking heightens inflammation throughout the body.


This shall clear your doubts on what food can cause appendicitis. Paying attention to what we eat is crucial to maintaining our general health and wellbeing. Our eating habits have a big impact on how well our digestion functions, and research indicates that some foods may make us more likely to get appendicitis.
