What are the worst foods that trigger IBS flare-ups? 

You have to avoid those foods that aggravate your bloating, cramps, constipation, or diarrhea. Some of the common triggering foods are:

Cruciform vegetables

These vegetables contain a specific sugar called raffinose which remains in the gut for a long time and takes time to get absorbed by the gut. It requires a high amount of good gut bacteria to ferment this sugar thus it causes bloating, constipation, and abdominal cramps when it remains longer in the stomach. The cruciform vegetables include:

• Cauliflower
• Cabbage
• Broccoli
• Bok choy
• Brussels
• Asparagus
• Sprouts
• Sweet potato

Beans

Beans are also a good source of protein and rich in fibers, but they contain oligosaccharides which are difficult to digest for the gut. So, they may act as triggering factors for IBS patients. These include:

• Lentils
• Soybeans
• Black
• Navu
• White
• Kidney

Fried food/Greasy food

Fried food becomes difficult to digest due to the high amount of unhealthy oil, and fat in it. It might pass through the GIT undigested and result in diarrhea. It includes:

• Chicken
• French fries
• Cakes
• Donuts
• Egg rolls

Spicy food

Avoid having red chilies in your food or spicy food as it may irritate the mucosal lining of the intestine and can cause abdominal cramps. 

Caffeine 

Avoid having tea, coffee, and chocolate as they can cause diarrhea especially when taken on an empty stomach. You can go for alternative drinks like green tea, and white tea which are low in caffeine.

Alcohol

Alcohol can worsen your IBS due to the high amount of sugar in it. Most commonly beer contains gluten which is found in wheat also and causes diarrhea and bloating in IBS patients. It also contributes to constipation by causing dehydration. Even if you take alcohol occasionally take care of the amount of sugar and drink plenty of water to prevent dehydration.  

Processed food

Processed food contains high amounts of sugar, salt, and fat to add flavor. Some good examples are:

• Chips
• Soft drinks
• Cheese
• Frozen meals
• Microwave or ready meals
• Frozen meat like bacon, sausage, salami

Garlic and Onions

Garlic and onions are also difficult to break down by the intestines and thus may cause gastric accumulation or bloating and abdominal cramps in IBS.
