Is Brown Rice Good for Gut Health?

Yes, brown rice can support gut health when it fits your digestive needs, because its fiber can aid regularity and nourish some gut bacteria. It is one option among the best foods for gut health, rather than a proven treatment for digestive problems.

Is brown rice a good choice for your gut?

Brown rice is a whole grain that retains its bran and germ. It generally contains more fiber than white rice, which has had those layers removed. Fiber can help keep bowel movements regular, although individual responses vary.

The direct evidence on brown rice and the gut microbiota is promising but limited. Studies have tested specially processed brown rice products, not established that an ordinary serving of cooked brown rice will relieve symptoms or produce a particular microbiome change.

How might brown rice support gut health?

The fiber in brown rice adds bulk to stool, which can help it move through the digestive tract. Some of its fiber and starch can also reach the large intestine, where gut microbes can use them. Microbial fermentation produces substances called short-chain fatty acids that play roles in the gut.

These mechanisms do not mean every person will feel better after eating brown rice. A sudden increase in fiber can cause gas or bloating, especially if your usual diet is low in fiber. The rest of your diet and your individual tolerance matter, too.

Feature	Brown rice	White rice
Grain structure	Retains the bran and germ	Bran and germ are removed
Fiber	Generally higher	Generally lower
Digestion	May help add bulk to stool but can cause bloating for some	May be easier to tolerate when a lower-fiber diet is needed

Drinking enough fluid also helps fiber work; see the best drinks for gut health for options.

What does the research on brown rice and gut health show?

In a 2022 randomized trial, 40 people with metabolic syndrome consumed a fermented brown rice beverage or a fermented white rice beverage as a main-meal replacement for 4 weeks. The brown rice beverage was associated with increases in certain bacterial types linked to short-chain fatty acid production. This was a small study of a fermented beverage in a specific population, so its results cannot be assumed to apply to plain cooked brown rice or everyone’s digestive health.

A 2024 human study compared specially heat-treated germinated brown rice with polished rice in people with high blood lipids over 3 months. The group eating the treated brown rice had greater measured microbial abundance and diversity. The product differed from ordinary brown rice, and a change in microbiome diversity alone does not establish relief of digestive symptoms.

Together, these studies suggest that brown rice products can influence gut microbes. They do not show that brown rice cures a gut condition or identify an ideal serving for gut health.

How can you use brown rice for gut health?

If you are not used to whole grains, start with a small serving of cooked brown rice and increase it gradually as tolerated. Notice whether it affects your bowel movements, gas or bloating. Drink enough fluid throughout the day, particularly as you add fiber.

Use brown rice as part of a varied eating pattern rather than relying on it as your only source of fiber. Pairing it with other foods you tolerate can make it easier to build a balanced meal. If brown rice consistently makes symptoms worse, choose foods that are more comfortable for you and discuss ongoing symptoms with a clinician.

Cook brown rice thoroughly, refrigerate leftovers promptly and avoid leaving cooked rice at room temperature for extended periods. Improperly stored rice can allow bacteria to grow and produce toxins that reheating may not reliably destroy.

Who should be careful with brown rice?

People with irritable bowel syndrome, inflammatory bowel disease or another digestive condition may tolerate fiber differently. If you have been advised to follow a low-fiber diet, or are experiencing a flare, ask your clinician or dietitian whether brown rice fits your plan. Do not stop prescribed treatment in favor of dietary changes.

Rice can contain inorganic arsenic, and brown rice often contains more than white rice because arsenic can accumulate in the outer layers. Vary your grains instead of depending on rice for most grain servings; this is especially important for children and during pregnancy. Rinsing rice can remove some arsenic, but it does not remove all of it.

Contact a clinician for persistent diarrhea, constipation, bloating or a lasting change in bowel habits. Seek urgent medical care for severe abdominal pain, blood in the stool or signs of significant dehydration.
