The hemorrhoid diet: foods that help and foods to limit

The hemorrhoid diet is a fiber and fluid plan. Soft, bulky stools are easier to pass, so you strain less, and less straining is one of the steps that keeps hemorrhoids from flaring. The daily target for most adults lands between 20 and 35 grams of fiber, with enough water that the fiber can soften the stool.

This page covers the gram targets, high-fiber foods by meal, how to raise fiber without spending a week bloated, the fiber-plus-water trial, and the foods that tend to cause trouble. How those meals fit a full day, including toilet time and movement, is on the prevention overview.

Only about 5 percent of people in the United States meet fiber recommendations, so a low starting point is normal ⁸. You are closing a gap, not chasing a perfect menu.

How much fiber you need each day

The NIDDK hemorrhoid diet page uses the Dietary Guidelines figure of 14 grams of fiber per 1,000 calories. On a 2,000 calorie day, that is 28 grams ¹. The constipation diet page gives the same idea as a range: 22 to 34 grams a day, depending on age and sex ².

Clinicians often round that to a single target. The American Academy of Family Physicians uses 25 to 35 grams a day as the first home treatment, along with a supplement, more water, warm soaks, and a stool softener if you need one ³. The American Society of Colon and Rectal Surgeons patient page says 20 to 35 grams, and that a fiber supplement once or twice a day suits most people ⁴.

There is a second, smaller clue from people who sit for work. In a 2026 survey of 421 sedentary professionals, hemorrhoids were present in 38.95 percent. Compared with people eating under 13.1 grams of fiber a day, those eating more than 18.5 grams had lower odds (adjusted odds ratio 0.56). The curve looked flatter near 25 grams a day, and the authors said that shape is a description, not a proven cutoff. The study was a snapshot, so it cannot show that raising fiber prevents new hemorrhoids ¹⁷.

A colonoscopy study of 2,813 adults found a similar pattern for grain fiber. The quarter of people eating the most grain fiber had about 22 percent lower odds of hemorrhoids than the quarter eating the least (odds ratio 0.78) ¹².

The calculator above adds up a normal day and shows the gap. The full fiber calculator page is there if you want to save a plan. Use it before you buy a supplement, so you know whether you are 5 grams short or 15.

High-fiber foods by meal

The gram amounts below are the ones the NIDDK prints, from federal food tables ¹. Other foods are good sources too. The constipation diet page names whole wheat bread and pasta, oatmeal, lentils, black beans, chickpeas, oranges, carrots, broccoli, almonds, peanuts, and pecans, without listing grams ². If a food is not in the table, read the package or use the calculator.

A day that lands near the 25 to 35 gram target, using only those portions:

That day is about 36 grams. Use it once your gut is used to the extra fiber. Half a cup of high-fiber bran cereal alone is 14 grams. If your current day is closer to 10 or 15 grams, that one bowl is a big jump. Start with the pear or the apple.

Leave the skin on apples, pears, and potatoes. That is how the NIDDK portions are measured ¹. Raspberries are 8 grams a cup if you want fruit instead of a second bean serving. A quarter cup of prunes is only 3.1 grams of fiber, so prunes are a small add unless you eat more of them. A constipation trial used 100 grams of prunes a day, which is well above a quarter cup, and that dose did help ¹¹.

How to raise fiber without getting miserable

The NIDDK says to add fiber a little at a time so your gut can adjust ². A 2022 review of 16 trials in adults with constipation explains why the pace matters. Fiber raised the chance of a response, and it increased gas. Stool frequency improved mainly when the supplement was over 10 grams a day and people stayed on it for at least 4 weeks. Psyllium and pectin were the fibers with a clear effect. Results varied a lot between studies ⁹.

A practical ramp, using the portions above:

1. For the first few days, add one fruit with the skin. A medium pear is 5.5 grams. A medium apple is 4.8 grams.
2. When gas is mild, add half a cup of beans at one meal. Kidney beans are 5.7 grams. Navy beans are 9.6 grams, so they are a bigger step.
3. Keep that plate for a week before you add a third high-fiber food. The hemorrhoid trials that checked more than once usually looked again at about 6 weeks ⁵.
4. If you are still short of about 25 grams, add a psyllium supplement rather than a second huge bowl of bran.

Psyllium is the supplement that matches the trials. In adults with chronic constipation, 5.1 grams of psyllium twice a day for two weeks raised stool water more than docusate sodium 100 mg twice a day. By week two, the psyllium group averaged 3.5 bowel movements a week and the docusate group averaged 2.9 ¹⁰. A separate four-week trial used 12 grams of psyllium a day. Two green kiwifruit a day and 100 grams of prunes a day were tested alongside it. All three increased complete bowel movements and reduced straining. Bloating improved in the kiwifruit group. Side effects were most common with psyllium and least common with kiwifruit ¹¹.

Kiwifruit and prunes are foods, so they sit on this page with the powder. They are options if a daily drink is the part you will skip. The bleeding results below are for fiber as a group. One constipation trial compared psyllium directly with a stool softener ¹⁰.

People who use an orange sugar-free psyllium powder often say it is easier to drink than they expected, as long as they finish the glass before it thickens. Some would rather skip the sweetener and coloring. A serving of orange fiber gummies is 5 grams of a blend, not psyllium, so one serving sits under the 10 gram supplemental dose that worked better in the constipation review ⁹. Powders, capsules, and gummies are compared on the fiber supplement page. How fiber stacks up against a stool softener or a laxative is in stool softener, fiber, or laxative, and short-term softeners are on the stool softener page.

Water, and the fiber plus water trial

Fiber without fluid can leave the stool thick. The NIDDK says water, fruit juice, and clear soups help fiber work, and that the right amount depends on your size, health, activity, and climate ^1,2. Ask your clinician if you are on a fluid limit.

The useful trial is specific. Researchers in Rome randomized 117 adults with chronic constipation, ages 18 to 50. For two months both groups ate about 25 grams of fiber a day. One group drank what they wanted and averaged 1.1 liters a day. The other was told to drink 2 liters of mineral water and averaged 2.1 liters. Both groups had more bowel movements and used fewer laxatives. The higher-fluid group improved more on both counts. The authors’ conclusion was that 25 grams of fiber helps, and that raising fluid to 1.5 to 2.0 liters a day makes the effect larger ⁷. A 1998 trial of fiber plus extra water is the study to read if you want the design.

The colon and rectal surgeons’ patient page suggests 8 to 10 glasses a day and says coffee, tea, and alcohol should not be counted, because they tend to dry you out ⁴. The NHS piles page says to cut back on alcohol and on caffeine, including tea, coffee, and cola, to avoid constipation ¹⁶. A glass of water with each high-fiber meal is a simple way to move toward the 2 liter mark without measuring every sip. Softer stools still need a short toilet visit. Straining and long sits are covered in toilet habits for hemorrhoids. A walk after a meal is the activity piece, on the exercise guide.

Foods that tend to cause trouble

If constipation is what sets off your hemorrhoids, the NIDDK says to limit foods with little or no fiber: cheese, chips, fast food, ice cream, meat, and many frozen snacks and processed dinners ¹. Meat can stay in the meal. The problem is a day built only from those foods, with no beans, fruit, or whole grains beside them. The same list appears on the constipation diet page, minus cheese and ice cream and plus the same processed meals ².

Spicy food is the item people ask about most. A randomized crossover trial gave 50 people with grade 2 or 3 hemorrhoids a chili capsule or a placebo at lunch. Over the next 48 hours, scores for bleeding, swelling, pain, itching, and burning stayed low with both. The authors saw no reason to ban an occasional spicy meal ¹³. A randomized chili-pepper trial in hemorrhoids is that paper. The longer write-up, including what the trial did not test, is in does spicy food cause hemorrhoids.

A French survey of people already seeing a doctor for a flare found a different pattern. A spicy diet in the prior two weeks was much more common among patients than among comparison patients (odds ratio 4.95), and so was alcohol (odds ratio 1.99). The authors used a looser statistical cutoff than most trials (P under 0.1) ¹⁴. After hemorrhoid surgery, chili looks more troublesome. Sixty people were randomized. The group who ate 3 grams of chili powder a day in the first week had higher pain scores (14.60 versus 7.97) and higher burning scores (12.90 versus 7.82). Bleeding and itching were not clearly different. They also used more pain medicine and had more frequent stools ¹⁵. Skip the daily chili while a surgical wound is healing. An occasional spicy meal, outside of that week, is a separate question, and the 48-hour trial did not show harm.

What fiber trials found for bleeding

Two write-ups cover the same seven trials and the same 378 people. One is a 2006 meta-analysis of seven fiber trials in the American Journal of Gastroenterology ⁵. The other is a Cochrane review of laxatives for hemorrhoids, and the laxative in those trials was fiber ⁶. They are not two independent piles of patients.

Both found that fiber cut the risk of bleeding in half (relative risk 0.50). The confidence interval runs from 0.28 to 0.89, so the true effect could be as small as an 11 percent drop or as large as a 72 percent drop ^5,6.

They differ slightly on overall symptoms. The journal paper said the risk of symptoms failing to improve fell by 47 percent (relative risk 0.53, interval 0.38 to 0.73) ⁵. The Cochrane review put that reduction at 53 percent (relative risk 0.47, interval 0.32 to 0.68) ⁶. The gap is how the same trials were pooled, not a second discovery. Studies that checked more than once, usually at about 6 weeks and at 3 months, stayed consistent ^5,6.

Pain, itching, and prolapse leaned toward fiber in the journal paper, and the ranges were wide enough that no effect is still possible (relative risks 0.33, 0.71, and 0.79) ⁵. The Cochrane authors said the same thing in words: those results could fit a large benefit, and the pooled numbers still tended toward no clear effect ⁶. They also flagged two limits: the studies were only moderate in quality, and unpublished negative trials might be missing ⁶. Mild side effects looked more common with fiber, but that finding was uncertain (relative risk 6.0, interval 0.57 to 64.8) ⁵.

A 2021 trial of kiwifruit, prunes, or psyllium is the food comparison if constipation is the piece you are treating ¹¹. A 2026 fiber survey in sedentary workers is the snapshot that found lower odds above 18.5 grams a day ¹⁷.
