19 Surprising Foods That Can Cause Constipation

If you are constipated, do not assume one food is always to blame. Constipation is more often linked to the whole pattern of eating too little fiber, drinking too little fluid, moving less, taking certain medicines, or having a digestive or medical condition.

Still, some foods can make the problem worse because they are very low in fiber, high in fat, heavily processed, or replace foods that would normally help keep stool soft and easy to pass.

That difference matters.

A slice of white bread does not suddenly cause chronic constipation. But a day built around white bread, chips, cheese, processed meat, pizza, and very little fruit, vegetables, beans, or whole grains can leave your digestive system short on the fiber and fluid it needs.

What Does Constipation Actually Mean?

Constipation is more than simply not having a bowel movement every day.

Your normal pattern may be different from someone else's. Medical sources commonly describe constipation as having fewer than three bowel movements a week, passing hard or dry stool, straining, having pain while passing stool, or feeling that stool has not fully passed.

You can therefore be constipated even if you still use the toilet several times a week.

Common causes include:

• Not eating enough fiber
• Not drinking enough fluids
• Low physical activity
• Ignoring the urge to have a bowel movement
• Changes in routine or travel
• Pregnancy
• Some medicines and supplements
• Irritable bowel syndrome
• Pelvic floor problems
• Diabetes
• Thyroid problems
• Neurological conditions
• Some intestinal diseases or blockages

That is why a list of foods is useful, but it cannot diagnose the cause.

How Can Food Make Constipation Worse?

Fiber is the biggest food related clue.

Your body does not fully digest dietary fiber. Different kinds of fiber can add bulk, hold water, soften stool, and support normal movement through the digestive tract.

A diet dominated by foods with little or no fiber leaves less material to help form soft, easy to pass stool.

Fat can matter too. Very fatty meals take longer to digest, and they often replace higher fiber foods on the plate.

Dehydration can make stool harder because the colon removes water from stool as it moves through the bowel.

So the pattern I look for first is:

That combination is much more useful than blaming one banana or one cup of coffee.

19 Foods That Can Cause Constipation or Make It Worse

These foods do not cause constipation in every person. Many become a problem mainly when they replace fruit, vegetables, legumes, whole grains, and enough fluid.

1. Fast Food

Burgers, fried chicken meals, fries, and similar fast foods tend to be low in fiber and high in fat.

If they make up a large part of your diet, there may simply be too little fiber rich food left in the day.

A simple improvement is to add vegetables, fruit, beans, or a whole grain side when possible.

2. Potato Chips

Potato chips are easy to eat in large amounts, but they provide little fiber compared with whole fruit, vegetables, nuts, seeds, or whole grains.

They can be part of a normal diet, but they are a poor main snack choice when constipation is already a problem.

Try fruit, nuts, popcorn, or a fiber rich snack more often.

3. Refined Crackers

Many crackers made mainly from refined flour contain little fiber.

A plate of crackers with cheese may give you almost no fiber at all.

Look for whole grain crackers or pair regular crackers with fruit, vegetables, hummus, or beans.

4. White Bread

White bread is made from refined flour that has much of the fiber rich bran and germ removed.

This makes it lower in fiber than whole grain bread.

If bread is a major part of your meals, switching some servings to whole grain bread can make a meaningful difference.

5. Refined Pasta

Regular white pasta is another refined grain.

Pasta itself does not automatically cause constipation. The problem is a meal built from refined pasta, creamy sauce, cheese, and meat with little plant food.

Add beans, lentils, vegetables, or use whole grain pasta for more fiber.

6. White Rice

White rice has less fiber than brown rice because the outer layers have been removed.

It is not a forbidden food.

But a large bowl of white rice with meat and no vegetables gives your bowel very little fiber to work with.

Add beans, lentils, vegetables, fruit, or choose a whole grain some of the time.

7. Pizza

Many pizzas combine refined flour, cheese, processed meat, and a high fat load while providing little fiber.

That combination explains why pizza appears so often on constipation food lists.

You do not have to ban it. Pair it with a large vegetable side, choose whole grain crust when available, and keep the rest of the day rich in fiber and fluid.

8. French Fries and Other Fried Foods

Fried foods tend to be high in fat and relatively low in fiber.

Examples include:

• French fries
• Fried chicken
• Onion rings
• Doughnuts
• Fried appetizers

If constipation is active, replacing some fried meals with baked, grilled, steamed, or roasted foods can help improve the overall diet pattern.

9. Doughnuts

Doughnuts combine refined flour, sugar, and fat while supplying little fiber.

They are a good example of a food that takes up space in the diet without adding much to stool bulk.

If you want something sweet, fruit with yogurt, oatmeal with berries, or a small dessert after a fiber rich meal may fit better.

10. Commercial Pastries and Cakes

Cakes, croissants, sweet rolls, cookies, and other baked desserts often share the same problem.

They are usually made from refined flour and contain a good amount of fat and sugar but little fiber.

An occasional dessert is not the issue. The concern is using these foods as breakfast and snack staples while fruit and whole grains disappear from the diet.

11. Processed Meats

Hot dogs, sausages, some deli meats, and similar processed meats contain little or no fiber.

A meat heavy sandwich made with white bread can therefore be a very low fiber meal.

Add vegetables, use whole grain bread, or pair the meal with beans, fruit, or a salad.

12. Large Meat Heavy Meals

Meat itself has no dietary fiber.

That does not mean chicken, fish, beef, or turkey must be avoided.

The issue appears when meat fills most of the plate and pushes out beans, vegetables, whole grains, or fruit.

A better plate has room for both protein and fiber.

13. Cheese Heavy Meals

Cheese contains protein and calcium but almost no fiber.

A meal built around cheese, refined bread, and meat can therefore be very low in the nutrient most linked with bowel regularity.

Johns Hopkins also lists cheese and high fat foods among foods that can worsen constipation for some people.

You do not need to eliminate cheese if you tolerate it. Add fiber around it.

14. Ice Cream and Rich Dairy Desserts

Ice cream is low in fiber and usually high in fat and sugar.

For most adults, dairy is not proven to be a universal cause of constipation. Some people, however, report harder stools or constipation with large amounts of dairy.

Children with cow milk protein sensitivity are a separate group and should be assessed by a healthcare professional rather than placed on an unsupervised dairy free diet.

15. Frozen Ready Meals

Many frozen meals are built from refined grains, meat, cheese, or creamy sauces and contain few vegetables or legumes.

Check the nutrition label rather than assuming all frozen food is bad.

A frozen meal with beans, whole grains, and vegetables may be quite different from a low fiber pizza or creamy pasta meal.

16. Packaged Snack Foods

Snack cakes, cheese puffs, sweet biscuits, and similar products tend to offer little fiber.

They also make it easy to fill up before eating the fruit, vegetables, beans, oats, or whole grains your bowel needs.

The problem is displacement.

A snack that gives you almost no fiber can crowd out one that would.

17. Unripe Green Bananas

This part of the old article needed correcting.

It is unripe green bananas, not ripe bananas, that are more often linked with a slowing or binding effect in some people.

Green bananas contain more resistant starch. As a banana ripens, much of that starch changes.

Ripe bananas also contain soluble fiber and do not need to be avoided by everyone with constipation.

Your own response matters.

18. Persimmons

Persimmons appear on several constipation food lists, especially astringent varieties eaten before they are fully ripe.

They contain tannins, which may slow intestinal movement in some people when eaten in large amounts.

This is not a reason to fear ripe persimmons. Treat them as a possible individual trigger rather than a universal cause.

19. Alcohol When It Replaces Fluid

Alcohol is not a food, but it belongs in this discussion because drinking heavily can make hydration harder to maintain.

Dehydration can contribute to hard, dry stool.

Alcohol may also replace water and disrupt normal meal patterns.

If constipation appears after nights of heavier drinking, hydration and the rest of the diet deserve attention.

Which Foods Have the Strongest Case?

The strongest message is not that 19 separate foods directly paralyze the bowel.

The stronger evidence points to food patterns that are:

• Low in fiber
• High in refined grains
• High in fat
• Heavy in processed foods
• Low in fruit and vegetables
• Low in legumes and whole grains
• Paired with too little fluid

The National Institute of Diabetes and Digestive and Kidney Diseases advises people with constipation to limit foods with little or no fiber, including chips, fast food, meat, prepared meals, and processed foods.

What About Bananas? The Ripeness Matters

The idea that “bananas cause constipation” is too simple.

An unripe green banana and a soft ripe banana are not nutritionally identical.

Green bananas contain more resistant starch, which can have a binding effect for some people. Riper bananas have less resistant starch and contain soluble fiber.

If bananas seem to worsen your symptoms, change the ripeness or portion and see what happens instead of removing all bananas forever.

Does Coffee Cause Constipation?

Not in the simple way the old article claimed.

Coffee actually stimulates colon movement in some people. Research has found effects on colonic motility with both caffeinated and decaffeinated coffee.

So coffee should not be listed as a universal constipating drink.

That said, very high caffeine intake may be a problem for someone who drinks little water, sleeps badly, or has an individual digestive trigger.

The practical answer is simple: notice your own response and keep your overall fluid intake adequate.

For a detailed look at morning drinks, water, coffee, prune juice, and gut health, read the NextFitLife Morning Drinks for Gut Health Guide.

Does Dairy Cause Constipation?

Sometimes, but not for everyone.

This is another area where online advice becomes too absolute.

Dairy foods are low in fiber, so a diet with lots of cheese, milk based desserts, and few plant foods can become low in fiber.

Some children may also develop constipation linked with cow milk protein sensitivity. In adults, however, the relationship between dairy and constipation is much less clear.

Lactose intolerance more commonly causes gas, bloating, abdominal pain, or diarrhea, although constipation can occur in some people.

Do not remove an entire food group without a reason, especially if you rely on it for protein or calcium.

Does Red Meat Cause Constipation?

Red meat has no fiber, but that does not prove beef itself directly causes constipation.

The more useful question is what came with it.

A steak with beans, vegetables, potatoes with skin, and water is very different from a meat heavy fast food meal with refined bread and fries.

If meat takes the place of nearly every fiber food on your plate, constipation risk can rise because the diet becomes low in fiber.

Does Chocolate Cause Constipation?

Chocolate is another individual trigger rather than a universal rule.

Milk chocolate bars and many chocolate desserts are high in fat and sugar and low in fiber.

Some people with IBS report constipation or other symptoms after chocolate, while many people tolerate it without a problem.

If chocolate seems to trigger symptoms, keep a short food and bowel diary before deciding that it must disappear from your diet.

What Should You Eat Instead?

For most people with mild constipation, the answer is not a special detox food.

Build more meals around foods that naturally supply fiber.

Which Foods May Help Constipation?

Useful choices include:

• Oats
• Beans
• Lentils
• Pears
• Apples with skin
• Berries
• Kiwi
• Prunes
• Vegetables
• Whole grains
• Chia seeds
• Ground flaxseed
• Nuts

Johns Hopkins notes that fiber helps add bulk and supports bowel movement, while prunes also contain sorbitol, a naturally occurring sugar alcohol that can help draw water into the bowel.

Do not suddenly eat huge amounts of these foods if your usual diet contains little fiber. That can leave you with gas, cramps, and bloating.

How Much Fiber Do Adults Need?

NIDDK advises that adults generally need about 22 to 34 grams of fiber each day, depending on age and sex.

That is a useful range, but do not jump from 10 grams to 30 grams overnight.

Increase fiber slowly.

For example:

1. Add fruit to breakfast.
2. Add vegetables to lunch.
3. Add beans or lentils several times a week.
4. Swap one refined grain for a whole grain.
5. Add oats, nuts, chia, or flax if they suit you.

Your digestive system has time to adjust when changes happen step by step.

Why Does Water Matter When You Add Fiber?

Fiber and fluid work together.

Your large intestine removes water from stool. If the stool loses too much water, it can become dry and hard.

Drinking enough fluid also helps some types of fiber form softer stool that is easier to pass.

There is no single water target that fits every adult. Needs change with body size, climate, exercise, pregnancy, illness, and medicines.

People with kidney disease, heart failure, liver disease, or another condition that requires a fluid limit should follow their medical team's advice.

More Fiber Is Not Always the Answer

This is an important part that simple food lists miss.

Constipation is not always caused by low fiber.

Some people have:

• Pelvic floor dysfunction
• Very slow colon movement
• IBS with constipation
• Medicine related constipation
• An intestinal blockage
• A neurological condition
• Another medical cause

In those situations, adding large amounts of bran or fiber may not solve the problem and can sometimes make bloating or discomfort worse.

Do not sharply increase fiber if you have severe abdominal pain, vomiting, major swelling, or an inability to pass stool or gas.

Those symptoms need medical care.

What About IBS With Constipation?

People with IBS C need a little more care with food lists.

A food can be high in fiber yet still trigger gas, pain, or bowel symptoms because it contains fermentable carbohydrates called FODMAPs.

Beans, onions, garlic, wheat, some fruits, and some dairy products can be triggers for certain people with IBS.

This does not mean everyone with constipation should remove them.

A low FODMAP diet is a structured short term approach followed by food reintroduction. It is not meant to become a lifelong list of banned foods.

Use the NextFitLife Gut Health and Digestion Guide for more on fiber, IBS, FODMAPs, and food tracking.

Medicines Can Cause Constipation Too

If your diet looks reasonable and constipation started after a new medicine, food may not be the main cause.

NIDDK lists several medicines and supplements that can contribute to constipation, including:

• Opioid pain medicines
• Some antidepressants
• Iron supplements
• Some antacids containing calcium or aluminum
• Some blood pressure medicines
• Some seizure medicines
• Some medicines used for Parkinson's disease

Do not stop a medicine by yourself.

Ask the prescriber or pharmacist whether constipation is a known side effect and what can be done safely.

Can Exercise Help Constipation?

Movement can help some people stay regular.

You do not need a hard workout.

Walking, light movement, and a regular daily routine may be enough to support bowel activity alongside fiber and fluids.

For simple options, use the NextFitLife Constipation Exercises Guide.

What If Constipation Comes With Bloating?

Constipation itself can cause bloating because stool and gas remain in the bowel longer.

The answer is not always more raw vegetables immediately.

If you suddenly add a large amount of beans, bran, chia, and raw vegetables, gas can rise before your bowel has adjusted.

Increase fiber slowly and track which foods you tolerate well.

For gentler food choices, see the NextFitLife Foods That Can Reduce Bloating Guide.

A Simple One Day Constipation Friendly Food Pattern

This is an example, not a medical meal plan.

Drink fluid through the day according to your health needs.

When Should You Get Medical Help?

Occasional mild constipation often improves with food, fluids, activity, and better bathroom habits.

Do not rely on dietary changes alone if constipation is severe or comes with warning signs.

NIDDK advises getting medical help promptly when constipation occurs with:

• Blood in the stool
• Rectal bleeding
• Constant abdominal pain
• Vomiting
• Fever
• Inability to pass gas
• Unexplained weight loss

Also speak with a healthcare professional if constipation keeps returning, does not improve with self care, begins suddenly without a clear reason, or becomes a major change from your normal bowel pattern.

Conclusion

The biggest lesson from these foods that cause constipation is that the whole diet matters more than one ingredient. Refined grains, fast food, fried foods, processed snacks, cheese heavy meals, and other low fiber foods are most likely to cause trouble when they replace fruit, vegetables, beans, whole grains, and enough fluid.

Start with one simple change today: replace one low fiber food with a higher fiber option, drink enough fluid for your health needs, and take a short walk if you can. If constipation is severe, persistent, painful, or comes with blood, vomiting, fever, weight loss, or an inability to pass gas, get medical care instead of trying another food remedy.
