The night before a colonoscopy, most people spend their time worrying about the prep drink. But the days leading up to it (and often the days after, if you’re managing a Crohn’s or ulcerative colitis flare) can be just as confusing, because suddenly the produce aisle and the whole grains you’ve been told to eat for years become off limits. If you’ve ever stood in a grocery store holding a bag of brown rice and wondering whether it counts as “safe,” you’re not alone. A low-residue diet asks you to temporarily eat the opposite of what most nutrition advice recommends, and that reversal can feel disorienting without a clear list to follow.

According to Mayo Clinic, a low-residue diet limits foods that add bulk (residue) to stool, which reduces the frequency and volume of bowel movements and can ease abdominal pain, cramping, and diarrhea during an active flare or before a bowel procedure. It’s distinct from a low-fiber diet in name only; in practice, the two overlap heavily, since fiber is the main driver of stool bulk. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) notes that many people with inflammatory bowel disease (IBD) use a low-residue approach temporarily during flares, then reintroduce fiber-rich foods once symptoms calm down. This grocery list is built to make that temporary window simpler, whether you’re prepping for a scope or riding out a flare with your care team’s guidance.

Whichever reason brought you here, the goal of this article is the same: take the guesswork out of the grocery store so you can spend your energy on feeling better, not decoding ingredient labels. Below you’ll find the rules behind the diet, a full shopping list organized by category, the foods to steer clear of, a sample day of meals, and practical prep tips to make the whole process feel manageable.

Key Rules for a Low-Residue Diet

Before you shop, it helps to understand the logic behind the list. A low-residue diet isn’t a lifestyle, it’s a short-term tool used for a specific medical reason, and the rules below explain why certain foods make the cut while others don’t.

  • This is typically a short-term, medically supervised plan. Most colonoscopy prep windows last one to three days, and IBD flare plans are usually reassessed by a gastroenterologist or registered dietitian within days to a few weeks, not indefinitely. This isn’t meant to become a permanent way of eating.
  • Aim for roughly 10 to 15 grams of fiber per day or less, compared to the 25 to 35 grams typically recommended for general health, per the Cleveland Clinic. That’s a significant drop, which is why so many everyday staples suddenly land on the “avoid” list.
  • Cook vegetables and fruits until soft, and remove skins, seeds, and peels whenever they’re allowed at all. Cooking breaks down some of the plant structure that would otherwise add bulk and residue.
  • Choose refined grains over whole grains. White bread, white rice, and low-fiber cereals digest with far less residue than their whole-grain counterparts, even though whole grains are usually the better everyday choice.
  • Stay hydrated and eat smaller, more frequent meals. Large meals can worsen cramping and urgency during a flare, and good hydration matters even more when fiber intake drops, since fiber and water normally work together to keep digestion moving smoothly.

Low-Residue Grocery List by Category

Print this out or screenshot it before you shop. Everything here fits within the general guidelines above, but always defer to any specific restrictions your doctor or dietitian has given you. Organizing your list by category also makes the trip faster, since you can move through the store section by section instead of doubling back for forgotten items.

One thing that surprises a lot of first-timers is that a low-residue grocery list often costs less and takes less prep time than a typical high-fiber shopping list, simply because many of the items are shelf-stable pantry staples rather than fresh produce that spoils quickly. Stocking up on canned fruit, white rice, and broth ahead of a scheduled procedure means you won’t need to make an emergency store run the night before your prep begins.

Proteins

  • Boneless, skinless chicken or turkey breast
  • Lean ground beef or turkey
  • Fish (cod, tilapia, salmon, canned tuna in water)
  • Eggs
  • Tofu (soft or silken)
  • Smooth peanut butter or other smooth nut butters, in small amounts if tolerated
  • Broth-based soups with strained or well-cooked, tender meat

Refined Grains

  • White bread, plain bagels, English muffins
  • White rice, including sushi rice and jasmine rice
  • Plain white pasta or noodles
  • Low-fiber cold cereals such as cornflakes, cream of rice, or cream of wheat
  • Plain crackers (saltines, water crackers)
  • White flour tortillas
  • Pretzels

Low-Fiber Fruits and Vegetables

  • Ripe bananas
  • Cantaloupe and honeydew melon
  • Canned or well-cooked peaches, pears, and applesauce (skinless)
  • Peeled, cooked potatoes (no skin)
  • Well-cooked carrots, green beans, and squash (peeled, seeds removed)
  • Strained tomato sauce or juice (no seeds or skins)
  • 100% fruit juice without pulp

Dairy (If Tolerated)

  • Milk, lactose-free milk, or fortified plant milk
  • Plain or flavored yogurt without seeds, fruit chunks, or granola mix-ins
  • Mild cheeses like mozzarella, cheddar, or American cheese
  • Cottage cheese
  • Pudding and custard

Some people with IBD are lactose intolerant or find dairy worsens symptoms during a flare. If that’s you, lactose-free or plant-based swaps can fill the same role without the discomfort. The Crohn’s & Colitis Foundation notes that dairy tolerance varies significantly from person to person, so this category is worth testing carefully rather than assuming it’s off the table entirely.

Fats and Extras

  • Butter, margarine, and vegetable oils
  • Mayonnaise
  • Smooth salad dressings without seeds or chunks
  • Honey, sugar, and clear jelly (no seeds, skins, or chunks of fruit)
  • Plain gravy
  • Salt, pepper, and mild herbs and spices in small amounts

Foods to Avoid

The foods on this list are usually the ones nutrition guidelines otherwise encourage, which is exactly why a low-residue diet can feel counterintuitive. During this short window, steer clear of:

  • High-fiber whole grains: whole wheat bread, brown rice, oats, quinoa, bran cereals, and whole-grain pasta
  • Seeds of any kind: sesame, poppy, chia, flax, and seed-bearing foods like strawberries, raspberries, and cucumbers with seeds intact
  • Skins and peels: apple skins, potato skins, tomato skins, and skin-on fruits in general
  • Raw vegetables: salads, raw broccoli, raw peppers, and other crunchy, uncooked produce
  • Legumes: beans, lentils, chickpeas, split peas, and other high-fiber legumes
  • Nuts and dried fruit: almonds, walnuts, trail mix, raisins, and dried apricots
  • Popcorn, coconut, and tough or stringy vegetables like celery and corn

According to MedlinePlus, these fiber-heavy foods pass through the digestive tract largely undigested, which is exactly the bulking effect a low-residue diet is trying to minimize, whether the goal is a clear colonoscopy view or a calmer gut during a flare. It also helps to double-check condiments and packaged foods, since ingredients like sesame seeds, dried fruit pieces, or whole-grain flour can hide in products you wouldn’t expect, such as salad dressings, granola bars, or multigrain crackers.

Sample Day of Eating

Here’s what a full day on a low-residue diet might look like in practice. Portion sizes and specific inclusions should still be checked against any instructions from your care team.

  • Breakfast: Scrambled eggs, a slice of white toast with a thin layer of jelly, and a half cup of peeled, cooked applesauce
  • Mid-morning snack: A ripe banana and a handful of pretzels
  • Lunch: Grilled chicken breast, white rice, and well-cooked, peeled carrots
  • Afternoon snack: Plain yogurt (no fruit chunks) and a few saltine crackers
  • Dinner: Baked cod, mashed potatoes without the skin, and strained tomato sauce over white pasta
  • Evening snack: Vanilla pudding or a small cup of cantaloupe

Notice the pattern: everything is cooked soft, peeled, seedless, and made from refined rather than whole grains. Smaller, more frequent meals like this tend to be easier on a sensitive gut than three large ones, and spacing meals out over the day can also help reduce the urgency and cramping that often come with a flare.

Prep Tips

  • Shop and prep in advance. If you know a colonoscopy or a flare is coming, batch-cook rice, shred chicken, and peel and cook a few days’ worth of vegetables ahead of time so you’re not scrambling later in the week.
  • Read labels closely. “Whole grain,” “multigrain,” and “seeded” varieties of bread, crackers, and cereal are easy to grab by mistake, especially since packaging often markets them as the healthier choice.
  • Strain what you can’t peel. A fine-mesh strainer turns homemade tomato sauce, fruit purees, and broths into low-residue versions of foods you’d otherwise have to skip entirely.
  • Keep a simple symptom log. If you’re managing a flare rather than a one-time prep, tracking which foods sit well helps you and your care team fine-tune the list over time.
  • Plan your transition back. Reintroduce fiber gradually once you’re cleared to, rather than jumping straight back to salads and whole grains in one meal, which can shock a gut that’s been on a lower-fiber pattern.
  • Stay ahead of hydration. Water, clear broths, and pulp-free juices support digestion even as fiber intake drops, and staying hydrated is especially important in the days surrounding a colonoscopy prep.

The Bottom Line

A low-residue diet is a narrow, purposeful tool, not a long-term eating pattern. For a colonoscopy, it’s usually just a day or two of preparation on top of the clear-liquid prep your doctor prescribes. For an IBD flare, it’s a way to give an inflamed gut a break from the mechanical work of digesting fiber while symptoms settle. Stocking your kitchen ahead of time with refined grains, tender proteins, peeled and cooked produce, and tolerated dairy makes the whole process far less stressful, so you can focus on feeling better rather than second-guessing every item in your cart.

It’s also worth remembering that a low-residue diet looks different for every person. Two people with Crohn’s disease, or two patients prepping for the same procedure, may tolerate slightly different foods, so treat this list as a starting framework rather than a rigid rulebook. Pay attention to how your own body responds, keep your care team in the loop, and adjust portions or specific items as needed.
