Are pineapples good for constipation?

Constipation is a common gastrointestinal issue that affects people of all ages. It is characterized by infrequent, difficult, or incomplete bowel movements. Some natural remedies like pineapple have been used to help relieve constipation. This article explores whether pineapples are an effective remedy for constipation.

What is Constipation?

Constipation refers to bowel movements that are infrequent or hard to pass. A person is considered constipated if they have fewer than three bowel movements per week or they strain excessively during bowel movements. Some common symptoms of constipation include:

  • Hard, dry, or lumpy stools
  • Straining during bowel movements
  • Feeling like you can’t completely empty your bowels
  • Abdominal pain or bloating
  • Decreased appetite

Constipation has many possible causes including:

  • Low fiber diet
  • Dehydration
  • Lack of physical activity
  • Stress
  • Certain medications like painkillers
  • Irritable bowel syndrome
  • Hypothyroidism

If you experience constipation for over 3 months, it is considered chronic constipation. This may require treatment from a doctor to identify any underlying medical conditions.

Are Pineapples a Natural Laxative?

Some people claim pineapple can help relieve constipation due to certain nutrients it contains. Pineapples are a good source of dietary fiber and bromelain enzymes, both of which may aid digestion:

  • Dietary fiber – Pineapples contain both soluble and insoluble fiber. Soluble fiber absorbs water to soften stool. Insoluble fiber adds bulk to stool and makes it easier to pass.
  • Bromelain enzymes – These enzymes found in pineapples help break down proteins. Some evidence suggests bromelain may also help relax muscles in the digestive tract.

The fiber and bromelain in pineapple may help relieve constipation by softening stool, adding bulk, and improving digestion. Pineapples also have a high water content which helps keep you hydrated and prevents hard stool.

Pineapple Nutrition Facts

Here is the nutrition profile of raw pineapple in a 1-cup serving (165g):

Nutrient Amount
Calories 82
Protein 1g
Carbs 22g
Fiber 2.3g
Vitamin C 131% DV
Manganese 76% DV
Bromelain 200-300 GDU/gram

Pineapples are very nutritious, being rich in vitamin C, manganese, and other micronutrients. They are also low in calories and fat.

Pineapple and Fiber for Constipation

Getting enough fiber is key for relieving constipation. The recommended daily fiber intake is 25-30 grams.

While pineapples contain fiber, they are not an exceptionally high source. Here is how the fiber in pineapple compares to other high-fiber foods:

Food Serving Fiber
Pineapple 1 cup 2.3g
Raspberries 1 cup 8g
Lentils 1 cup 16g
Oatmeal 1 cup 4g
Chia seeds 1 ounce 10g

While pineapple contains some fiber, you would need to eat a large quantity to significantly increase your fiber intake. Other foods like lentils, chia seeds, and raspberries contain much more fiber per serving.

How Much Pineapple for Constipation Relief?

There are no guidelines for exactly how much pineapple to eat to relieve constipation. To get a significant amount of fiber from pineapple, you would likely need to eat at least 2-3 cups.

Some sources suggest eating up to 1 whole pineapple per day, which provides:

  • Approximately 13 grams of fiber
  • Over 200% DV vitamin C
  • 100% DV manganese

However, eating this much pineapple every day long-term is not recommended as it may cause digestive issues due to the high acidity.

The bromelain enzymes in pineapple may also interact with certain medications like blood thinners and antibiotics. It’s best to enjoy pineapple in moderation as part of a balanced diet.

Other Foods That May Help with Constipation

In addition to pineapple, there are many other foods that can help improve bowel regularity. Some examples include:

  • Prunes – Contain fiber and sorbitol, which acts as a natural laxative
  • Figs – High in fiber and may promote bowel regularity
  • Kiwi – Rich in fiber and actinidin enzymes that aid digestion
  • Flax and chia seeds – Excellent sources of soluble and insoluble fiber
  • Beans and lentils – Legumes are very high in fiber
  • Leafy greens – Spinach and kale provide fiber and magnesium to help relieve constipation

Focusing on a diet with plenty of high-fiber fruits, vegetables, whole grains, beans, nuts and seeds can help increase your fiber intake and prevent constipation.

Other Constipation Remedies

In addition to eating high-fiber foods, there are some other natural ways you can help relieve constipation:

  • Drink more water – Staying hydrated softens your stool and aids elimination.
  • Exercise – Physical activity stimulates the bowels.
  • Establish bathroom routine – Going to the bathroom at the same time every day trains your body.
  • Probiotics – Probiotic foods like yogurt help improve gut health.
  • Magnesium supplements – Magnesium helps relax the intestinal muscles.
  • Tea – Certain herbal teas like chamomile and senna act as laxatives.

For severe or chronic constipation, there are also some over-the-counter laxatives and stool softeners that can provide relief. But these should only be used for short periods.

When to See a Doctor

You may need to talk to your doctor if:

  • You’ve had symptoms for over 3 months
  • Laxatives or natural remedies don’t help
  • You see blood in your stool
  • Constipation is accompanied by pain or vomiting
  • You have risk factors like advanced age, family history of colon cancer, recent blood work changes

A doctor can help identify any underlying cause and provide effective treatment options specific to your case.


Pineapples contain beneficial enzymes and fiber that may help food move through the digestive tract. However, pineapples are not an exceptionally high fiber fruit. You would need to eat a large amount to significantly increase your fiber intake.

Pineapple can be included as part of a balanced diet with plenty of high-fiber foods. But it should not be relied on as the sole solution to constipation issues. Make sure to also drink enough fluids, exercise, and consider other dietary and lifestyle remedies. See your doctor if constipation persists despite home treatment.
