What are the best foods to help constipation?
In Dr. Khan's guidance, five of the best foods to help constipation are prunes, kiwifruit, ground flaxseed or chia seeds, beans and lentils, and oats or wheat bran. Prunes and kiwifruit have been shown in studies to improve stool frequency and softness; seeds, legumes and whole grains add fiber that holds water and adds bulk. They work best eaten every day, introduced gradually, with plenty of fluid.
Five foods that keep you regular
- PrunesFiber plus sorbitol that draws water into the bowel.
- KiwifruitAbout two a day improve softness and frequency for many adults.
- Flax or chiaSoluble fiber that forms a softening gel; soak chia first.
- Beans and lentilsRich in both fiber types; start with small portions.
How much of each food should I eat?
A practical daily target is a small handful of prunes (about 4 to 6) or a small glass of prune juice, two green kiwifruit, 1 to 2 tablespoons of ground flaxseed or soaked chia seeds, a half-cup serving of cooked beans or lentils, and a bowl of oatmeal or bran cereal. You do not need all five every day; aim to reach about 25 to 35 grams of fiber in total and increase slowly.
| Food | Daily serving idea | Tip |
|---|---|---|
| Prunes | 4 to 6 prunes or a small glass of juice | Often works within a day |
| Kiwifruit | 2 green kiwifruit | Skin is edible and adds fiber |
| Flaxseed or chia | 1 to 2 tablespoons | Use ground flax; soak chia before eating |
| Beans and lentils | 1/2 cup cooked | Start small to limit gas |
| Oats or bran | 1 bowl at breakfast | Add fruit for extra fiber |

What does a constipation-friendly week look like?
A simple constipation-friendly week might rotate oatmeal with ground flaxseed and kiwi at breakfast, lentil soup or a bean salad at lunch, and vegetables with whole grains at dinner, with prunes as a daily snack and water through the day. Keeping the same core foods most days builds a steady routine your bowel can follow.
- Breakfast: oatmeal with 1 tablespoon ground flax and a sliced kiwi
- Snack: 4 to 6 prunes and a glass of water
- Lunch: lentil soup or black bean salad
- Dinner: vegetables, brown rice or whole-grain pasta, lean protein
- Evening: chia pudding made with milk or yogurt
Tip: Add one food per week
Start with prunes or kiwi in week one, then add flax or chia, then beans. Adding foods gradually avoids gas and bloating and shows you which ones help most.
Why is water so important with these foods?
Fiber softens stool by holding water, so without enough fluid it can make constipation worse rather than better. Drink water steadily through the day and a little more as you add fiber, especially in Texas heat or when you exercise. People with heart or kidney conditions who limit fluids should ask their doctor how much to drink.

When should constipation be checked by a doctor?
See a doctor if constipation lasts more than three weeks despite diet changes, needs laxatives regularly, or is a new change in your bowel habits, and get prompt care for blood in the stool, black stools, weight loss, anemia, severe pain, vomiting or a swollen belly. Adults 45 and older should also be up to date on colorectal cancer screening.
