3 min read

According to the CDC, viral gastroenteritis, commonly called the stomach flu, leads to millions of illnesses and hundreds of thousands of hospitalizations each year in the U.S.. When this highly contagious infection strikes, knowing which fruit is good for stomach flu can make a significant difference in managing symptoms like diarrhea and nausea.

Quick Summary

This article explores which fruits are best for soothing the digestive system and replenishing electrolytes during a stomach flu. It details easy-to-digest options like bananas and applesauce while also highlighting fruits to avoid due to their high fiber or acidity content.

Key Points

Bananas are Best: The high potassium in bananas helps replenish electrolytes lost from vomiting and diarrhea, while their bland, soft texture is gentle on a sensitive stomach.
Applesauce Soothes Diarrhea: Unsweetened applesauce contains pectin, a soluble fiber that absorbs fluid in the digestive tract and can help firm up loose stools.
Avoid Acidic Fruits: Citrus fruits like oranges and grapefruits can irritate the stomach lining due to their high acidity, potentially worsening nausea and heartburn.
Choose Cooked over Raw: Cooking fruits and removing the skin significantly reduces their fiber content, making them easier to digest when your stomach is sensitive.
Hydrate with Water-Rich Melons: During later stages of recovery, hydrating fruits like watermelon and cantaloupe can help replenish fluids and electrolytes.
Reintroduce Gradually: Start with the blandest options first and slowly add other fruits as your digestive system recovers to avoid irritating your stomach further.

Navigating a Stomach Flu: The Role of Fruits

When you're dealing with the stomach flu (viral gastroenteritis), your digestive system is incredibly sensitive. The key is to consume foods that are easy to digest, help replenish lost fluids and electrolytes, and don't further irritate your gut. Bland, low-fiber fruits and cooked options are often the best choices, as they provide essential nutrients without overworking your system.

The BRAT Diet and Other Easy-to-Digest Fruits

For decades, the BRAT diet (Bananas, Rice, Applesauce, Toast) has been a go-to recommendation for individuals suffering from gastrointestinal distress. Although modern nutritional advice suggests expanding beyond such a restrictive diet quickly, its core fruit components are still highly beneficial.

Bananas: These are a cornerstone for stomach flu recovery for several reasons. They are soft, bland, and easy on the stomach. Rich in potassium, they help replenish electrolytes lost through vomiting and diarrhea. The soluble fiber in bananas can also help add bulk to loose stools.
Applesauce: A cooked, peeled apple product, applesauce is much easier to digest than a raw apple with the skin. It contains pectin, a soluble fiber that absorbs excess water in the gut, which can help firm up stools during a bout of diarrhea.
Peeled Pears and Peaches: Similar to applesauce, peeled and cooked pears or peaches are gentle options. Cooking helps to break down the fiber, making them easier to tolerate for a sensitive stomach.
Melons (Watermelon, Cantaloupe, Honeydew): Once you can tolerate solid food again, water-heavy fruits like melons are excellent for rehydration. They are mostly water and contain important vitamins and minerals.

Fruits to Avoid During Stomach Flu

Just as important as knowing what to eat is knowing what to avoid. Certain fruits can worsen stomach flu symptoms due to their high acidity, high fiber content, or natural laxative effects.

Citrus Fruits: Oranges, grapefruits, lemons, and limes are very acidic and can irritate the stomach lining, exacerbating nausea and heartburn.
Raw and Unpeeled Fruits: The high insoluble fiber in the skin and pulp of raw fruits like berries can aggravate diarrhea by speeding up digestion.
Prune and Other Laxative Fruits: Prunes, figs, and papaya can have a laxative effect, which is the opposite of what is needed during diarrhea.
Fruit Juices with Pulp: While clear juices like diluted apple juice can be hydrating, those with pulp contain fiber that can be harsh on a sensitive stomach.

How to Introduce Fruits Back into Your Diet

Your body's ability to tolerate food will change as you recover. Begin with small, frequent meals rather than three large ones.

Start with Bland Options: Begin with bananas or unsweetened applesauce. These are the most gentle options and are least likely to cause a reaction.
Move to Cooked, Peeled Fruits: After a day or two of tolerating the initial bland fruits, you can introduce other cooked and peeled options like pears or peaches.
Introduce Water-Rich Melons: Once you feel more stable, hydrating fruits like watermelon can be added back into your diet.
Gradual Reintroduction of Raw Fruits: Only after full recovery should you consider reintroducing raw fruits and their skins, as these can be more challenging for the digestive system.

The Importance of Hydration

Beyond food, staying hydrated is the most crucial part of stomach flu recovery. Vomiting and diarrhea lead to significant fluid and electrolyte loss. While fruits like bananas help replenish potassium, oral rehydration solutions, broths, and water are essential to maintain proper fluid balance.

Conclusion

For a swift and smooth recovery from the stomach flu, selecting the right fruits is key. Bland, low-fiber, and cooked fruits like bananas and applesauce are your best friends in the early stages, helping to soothe the stomach and restore essential electrolytes. While focusing on gentle reintroduction, remember to avoid acidic or high-fiber fruits that could worsen symptoms. Pairing these fruits with consistent hydration is the most effective strategy to help your body heal and get back on its feet.

Frequently Asked Questions

A banana is excellent for the stomach flu because it is part of the BRAT diet, providing binding, low-fiber content that helps firm up loose stools. It is also rich in potassium, an important electrolyte that gets depleted during vomiting and diarrhea.

It is generally better to eat cooked apples (like applesauce) or peeled and cooked apples when you have the stomach flu. The high insoluble fiber in raw apple skin and pulp can be too harsh for a sensitive digestive system and may worsen diarrhea.

Citrus fruits like oranges and grapefruit should be avoided because their high acidity can irritate the stomach lining, potentially increasing nausea, abdominal pain, and heartburn.

Once you have successfully tolerated bland foods like bananas and applesauce for a day or two, you can gradually introduce other easy-to-digest, cooked, or peeled fruits like pears and peaches. Water-rich melons can also be added for hydration.

Clear, pulp-free fruit juices like diluted apple juice are often recommended for hydration, but concentrated, sugary, or citrus juices should be avoided as they can upset a sensitive stomach and worsen diarrhea.

Cooking a fruit helps to break down its fiber content, making it easier for a sensitive stomach to digest. Raw fruits, especially those with skins, have more fiber that can speed up digestion and aggravate diarrhea.

No, dried fruits should be avoided during a stomach flu as they are typically high in fiber and can have a laxative effect, which would be counterproductive when dealing with diarrhea.
