8 Foods to Avoid for Bloating

May 12, 2025

Bloating is a common digestive issue that affects nearly 30% of people on a regular basis. It often leads to a swollen, tight feeling in the stomach, especially after eating. While it can be linked to medical conditions, in most cases, it is caused by gas buildup or how certain foods are broken down during the digestive process.

Foods like beans, carbonated drinks, dairy products, gluten, salty snacks, apples, and cruciferous vegetables (such as broccoli) are common culprits. These can cause excess gas or water retention, especially in people with food sensitivities.

The good news? Simple diet changes can significantly reduce bloating.

In this guide, we’ll cover the top foods that commonly trigger bloating and offer smarter alternatives to help you eat more comfortably.

8 foods that cause bloating and discomfort

Some foods are known to cause bloating more than others. Below, we’ll discuss the eight worst foods for bloating and explain why they have this effect on your body.

1. Beans and lentils

Beans and lentils are known for their high fiber and protein content, making them an excellent source of nutrition. However, they also contain certain sugars and carbohydrates that can cause bloating.

Why do they cause bloating

Beans and lentils contain oligosaccharides—complex sugars that your body struggles to break down. Since your body doesn’t have the enzyme to digest these sugars, they pass through to the large intestine, where they ferment. This fermentation produces gas, which can cause bloating, discomfort, and sometimes diarrhea.

How to manage

You can reduce the bloating effects of beans and lentils by soaking them overnight before cooking. This helps break down some of the oligosaccharides, making them easier to digest. Additionally, gradually increasing your fiber intake can help your digestive system adjust to these foods.

2. Dairy products

Dairy products, including milk, cheese, and yogurt, are essential in many diets for their calcium and vitamin D content. However, for many people, consuming dairy can result in bloating.

Why do they cause bloating

Dairy contains lactose, a sugar that some people cannot properly digest due to a lack of the enzyme lactase. When lactose isn’t digested, it reaches the large intestine, where it ferments, producing gas and causing bloating. This is especially common in people with lactose intolerance.

How to manage

If you suspect you’re lactose intolerant, try lactose-free dairy options or alternatives like almond milk, soy milk, or coconut yogurt. Some probiotic-rich yogurts may also aid digestion by helping to break down lactose. If dairy consumption is causing persistent issues, consider consulting a healthcare professional.

3. Cruciferous vegetables

Cruciferous vegetables, such as broccoli, cauliflower, cabbage, and Brussels sprouts, are packed with nutrients like vitamins, fiber, and antioxidants. However, they can cause bloating due to their complex composition.

Why do they cause bloating

These vegetables contain a type of sugar called raffinose, which can be difficult for some people to digest. Like beans, raffinose is fermented by bacteria in the large intestine, producing gas that causes bloating.

To further relieve constipation and support overall gut health, consider The Good Bug's Smooth Move Fiber Boost.

How to manage

Steaming or cooking cruciferous vegetables can make them easier to digest. Cooking breaks down some of the fiber and sugars, reducing the chances of fermentation in the gut. Start with small portions to see how your digestive system reacts, and gradually increase the amount if necessary.

4. Carbonated beverages

Sodas, sparkling waters, and other carbonated drinks are popular choices for quenching thirst, but they can leave you feeling bloated.

Why do they cause bloating

Carbonated drinks contain carbon dioxide, which creates bubbles and gas. When you consume these drinks, the gas gets trapped in your digestive system, leading to bloating and discomfort. Additionally, sugary sodas and artificially sweetened beverages may further disrupt digestion, contributing to bloating.

How to manage

If you enjoy fizzy drinks, opt for still water or herbal teas to stay hydrated. If you prefer something fizzy, choose sparkling water without carbonation or flavored with a splash of lemon or lime. Avoid soda and sugary drinks, as they are known to exacerbate bloating.

5. Processed foods

Processed foods are a major contributor to bloating, primarily due to their high sodium content and use of preservatives.

Why do they cause bloating

Processed foods are often high in sodium, which can lead to water retention in the body. When your body holds on to excess water, it can cause a feeling of bloating and puffiness. Additionally, processed foods often lack fiber, making them harder to digest and contributing to gas buildup.

How to manage

Focus on fresh, whole foods to reduce bloating. Cooking meals at home using fresh ingredients allows you to control the amount of salt and preservatives. Choose unprocessed snacks and meals when possible, and read food labels to avoid hidden sources of sodium.

6. Artificial sweeteners

Many sugar substitutes, such as sorbitol, xylitol, and mannitol, are commonly used in sugar-free gum, candies, and beverages. While these sweeteners help lower sugar intake, they can be a major cause of bloating.

Why do they cause bloating

The body does not fully absorb artificial sweeteners. As they move through the digestive tract, they ferment in the large intestine, producing gas that can lead to bloating. These sweeteners can also draw water into the intestines, causing further discomfort.

How to manage

Limit your intake of sugar-free products containing artificial sweeteners. If you’re looking for a sweet alternative, try natural sweeteners like stevia or monk fruit, which are gentler on your digestive system and less likely to cause bloating.

7. Fried foods

Fried foods are often delicious, but they can be tough on your digestive system, particularly if you’re prone to bloating.

Why do they cause bloating

Fried foods are high in fat, and fats take longer to digest than other nutrients. This can lead to delayed stomach emptying, making you feel full, heavy, and bloated. Additionally, fried foods can stress your gut, leading to gas buildup.

How to manage

Opt for healthier cooking methods, such as baking, grilling, or steaming. If you do indulge in fried foods, choose smaller portions to avoid overwhelming your digestive system. Pair fried foods with fiber-rich vegetables to help balance digestion.

8. Excessive salt

Consuming too much salt can lead to water retention, making you feel bloated and sluggish. Salt is commonly found in processed foods, canned goods, and restaurant meals.

Why does it cause bloating

High sodium levels in the body cause it to hold onto water, leading to bloating. When you consume too much salt, your body may retain excess water, which increases the feeling of puffiness and discomfort.

How to manage

Reduce your intake of salty foods, especially processed snacks and fast food. Opt for fresh, whole foods, and use herbs and spices to season your dishes instead of salt. Always check food labels for sodium content to ensure you’re not consuming too much salt.
