Rice for an Upset Stomach: The Benefits of White Rice
When dealing with acute digestive distress, such as diarrhea, nausea, or stomach flu, doctors often recommend sticking to bland, easily digestible foods. Plain white rice is a top choice in this category for several reasons.
Unlike whole grains, white rice has its fibrous bran and germ layers removed during processing. This significantly reduces its fiber content, making it less work for the digestive system to break down. The bland, starchy nature of white rice can also help bind loose stools, which is why it's a key component of the BRAT (Bananas, Rice, Applesauce, Toast) diet for short-term relief. A plain bowl of boiled white rice can calm an irritated digestive tract, providing simple carbohydrates for energy without exacerbating symptoms.
How to prepare white rice for digestive issues
- Use a high water-to-rice ratio to achieve a soft, porridge-like consistency.
- Cook it plain, without any added butter, oils, or spices that could further irritate a sensitive stomach.
- Consider eating smaller, more frequent portions rather than large meals to avoid overwhelming your system.
Brown Rice and the Gut Microbiome
While white rice is ideal for a sensitive or upset stomach, brown rice and other whole-grain varieties offer greater benefits for long-term gut health when your digestive system is functioning normally. The key difference lies in the high fiber content of brown rice.
Brown rice retains its bran and germ, which are packed with dietary fiber. This fiber plays a crucial role in maintaining a healthy gut microbiome by acting as a prebiotic. Prebiotics are food for the beneficial bacteria in your large intestine, which in turn produce short-chain fatty acids (like butyrate) that nourish gut cells, reduce inflammation, and improve overall digestive function. The fiber also promotes regular bowel movements, helping to prevent constipation.
For those not accustomed to a high-fiber diet, introducing brown rice gradually is a good strategy. Starting with small portions and increasing them over time allows your gut bacteria to adjust, minimizing the risk of gas and bloating.
The Power of Resistant Starch
Both white and brown rice contain resistant starch, a special type of carbohydrate that our bodies cannot fully digest in the small intestine. This starch travels to the large intestine, where it is fermented by gut bacteria, much like soluble fiber.
Interestingly, you can increase the amount of resistant starch in rice by cooking and then cooling it. As the rice cools, some of the starch molecules rearrange into a form that is resistant to digestion. This means that reheating leftover rice can actually increase its gut-health benefits.
- Benefits of resistant starch:
- Feeds beneficial gut bacteria, promoting a healthy microbiome.
- Acts as a prebiotic, producing beneficial compounds that support gut health.
- Leads to a slower and more gradual increase in blood sugar levels compared to freshly cooked rice.
- Increases feelings of fullness, which can assist with weight management.
White Rice vs. Brown Rice for Digestion
| Feature | White Rice | Brown Rice |
|---|---|---|
| Fiber Content | Low | High |
| Ease of Digestion | Easier for sensitive stomachs | Can cause gas/bloating initially for some |
| Nutrient Profile | Fewer vitamins and minerals (but often enriched) | Richer in B vitamins, magnesium, selenium, and antioxidants |
| Use for Diarrhea | Recommended for binding stools | Not recommended; high fiber can worsen symptoms |
| Use for Constipation | Can be binding; not the best choice | Excellent due to high fiber content |
| Impact on Bloating | Less likely to cause bloating | Can cause bloating if not accustomed to high fiber |
Who Should Choose What?
Your choice between white and brown rice for optimal digestive health depends on your current situation:
- For an upset stomach: Opt for plain white rice. Its bland, low-fiber nature is gentle and can help soothe and firm up your stools.
- For long-term gut health: Choose brown rice most of the time. Its higher fiber content acts as a prebiotic, fostering a healthy and diverse gut microbiome.
- For sensitive bowels (e.g., IBS flair-ups): White rice might be a safer choice during symptom flares. However, some individuals with IBS tolerate brown rice well, so monitoring your body's response is key. A food journal can be a valuable tool to track which rice works best for you.
Potential Drawbacks and Considerations
While rice is generally well-tolerated, there are a few important points to consider.
Bloating and gas
For those with sensitive digestion or conditions like irritable bowel syndrome (IBS), the high fiber in brown rice can sometimes cause bloating, gas, and discomfort. It is a good idea to introduce brown rice slowly and in small amounts to allow your digestive system to adapt. Pairing it with protein and healthy fats can also help slow down digestion and manage blood sugar spikes.
Arsenic content
Some concerns exist regarding arsenic levels in rice, as the plant tends to absorb it from the soil. Brown rice tends to have higher arsenic levels because the outer bran layer is where arsenic accumulates. However, the risk is generally low, and simple preparation methods can significantly reduce arsenic content, such as rinsing rice thoroughly before cooking and using a higher water-to-rice ratio during cooking.

Conclusion
Ultimately, the question of whether is rice good for your stomach has a nuanced answer. The type of rice, your current state of health, and your long-term digestive goals all play a role. For short-term relief from an upset stomach, bland, low-fiber white rice is the clear winner. For long-term digestive health and promoting a healthy gut microbiome, brown rice with its prebiotic fiber is superior. By understanding the differences and listening to your body, you can make an informed choice that supports your specific nutritional needs.
