Nutrition Diet: What foods should you avoid when you have a food infection?

4 min read

According to the Centers for Disease Control and Prevention, approximately 1 in 6 Americans get sick from a foodborne illness each year. Understanding what foods should you avoid when you have a food infection? is critical for managing symptoms, preventing further irritation to your gastrointestinal tract, and promoting a faster, more comfortable recovery.

Quick Summary

During recovery from a food infection, it is best to avoid fatty, spicy, and acidic foods, as well as dairy and caffeinated beverages, which can worsen symptoms. Focus on hydration and bland, low-fiber foods to support your digestive system.

Key Points

  • Fatty and Fried Foods: Avoid high-fat and fried foods, as they are difficult to digest and can worsen nausea and bloating.

  • Spicy and Acidic Foods: Stay away from spicy foods and acidic fruits and vegetables, which can irritate the sensitive stomach lining during recovery.

  • High-Fiber Foods: Temporarily limit high-fiber foods to reduce digestive strain, as they can be tough for an inflamed gut to process.

  • Dairy Products: Skip milk and high-fat dairy, as a temporary lactose intolerance can develop after a gastrointestinal infection.

  • Caffeine and Alcohol: Avoid beverages with caffeine and alcohol, as they can cause dehydration and further irritate your digestive system.

  • Prioritize Hydration: Focus on drinking plenty of clear fluids like water, broth, or oral rehydration solutions to prevent dehydration.

  • Reintroduce Bland Foods: Start eating bland, easy-to-digest foods like bananas, rice, applesauce, and toast when your appetite returns.

A food infection, often mistakenly called food poisoning, is caused by ingesting food contaminated with bacteria, viruses, or parasites. The resulting inflammation and irritation in your stomach and intestines can cause symptoms like nausea, vomiting, and diarrhea. To help your body heal, it's essential to rest your digestive system and choose foods that won't aggravate your symptoms. This means temporarily excluding certain foods and focusing on a gentle, bland diet.

High-Fat and Fried Foods

Fat is harder for the body to digest than carbohydrates or protein, especially when your stomach is already inflamed. Consuming high-fat foods during a food infection can slow down gastric emptying, leading to increased feelings of bloating and nausea. Avoiding these items is crucial for a smoother recovery.

Examples of high-fat foods to avoid:

  • Fried foods (e.g., french fries, fried chicken)
  • Fast food, including pizza
  • Fatty cuts of meat
  • Processed cheeses and full-fat dairy
  • Foods prepared with excessive butter or oil

Spicy and Acidic Foods

Spicy foods can irritate the stomach lining, while acidic foods can increase stomach acid production, both of which can exacerbate symptoms like nausea, heartburn, and abdominal discomfort during recovery. Keeping your diet as bland as possible is the safest approach.

Foods in this category to avoid:

  • Chili peppers and hot sauces
  • Curries and heavily seasoned foods
  • Citrus fruits (oranges, lemons, grapefruits)
  • Tomatoes and tomato-based products (e.g., sauces, ketchup)
  • Pickles and other high-acid foods

High-Fiber Foods

While fiber is a key component of a healthy diet, it can be difficult for an inflamed gastrointestinal system to process. Temporarily limiting high-fiber foods can reduce bloating, cramping, and excessive bowel movements. It is wise to transition back to a high-fiber diet gradually as your stomach heals.

Foods to temporarily limit:

  • Whole grain breads and cereals
  • Brown rice and wild rice
  • Raw vegetables, such as broccoli and leafy greens
  • Legumes and beans
  • Nuts and seeds
  • Most raw fruits (especially with skin)

Dairy Products and Lactose Intolerance

After a gastrointestinal infection, it is common to experience a temporary decrease in lactase, the enzyme needed to digest lactose in dairy products. This can lead to temporary lactose intolerance, causing gas, bloating, and diarrhea. Avoiding most dairy can help prevent these complications during recovery.

Dairy to avoid:

  • Milk and ice cream
  • Soft cheeses
  • Butter and cream-based products

It is important to note that some fermented dairy products, like yogurt with live cultures, may be tolerated better and can even help restore beneficial gut bacteria.

Sugary and Caffeinated Beverages

Sugary drinks can draw water into the intestines, potentially worsening diarrhea. Caffeine acts as a diuretic and can stimulate the colon, which can exacerbate symptoms and increase dehydration.

Drinks to stay away from:

  • Coffee and caffeinated teas
  • Energy drinks and sodas
  • Highly sweetened fruit juices
  • Alcohol

Foods and Drinks for a Gentle Recovery

When you feel ready to eat, the focus should be on gentle, easy-to-digest foods. Hydration with clear fluids is paramount, especially if you have been vomiting or experiencing diarrhea. Drinking small, frequent sips of fluid is often better tolerated than large amounts.

Hydrating and soothing options:

  • Water and diluted fruit juices (like watered-down apple or grape juice)
  • Clear broths or consommé
  • Herbal teas, such as ginger or chamomile, which can help soothe the stomach
  • Oral rehydration solutions to replenish lost electrolytes

Bland foods for reintroduction:

  • The BRAT diet: Bananas, white rice, applesauce, and white toast
  • Saltine crackers
  • Plain boiled potatoes or sweet potatoes
  • Plain oatmeal
  • Skinless, baked chicken or turkey

Conclusion

Navigating your diet during a food infection is about giving your body the space and resources it needs to heal. By temporarily eliminating irritating foods like high-fat, spicy, and high-fiber items, you can minimize digestive distress and reduce symptoms. Rehydrating properly and gradually introducing bland, easy-to-digest foods are the cornerstones of a successful recovery. Always listen to your body, and if symptoms are severe or persistent, it's important to consult a healthcare professional for guidance. For more information on eating during recovery, consult resources like the National Institutes of Health.

Frequently Asked Questions

During a food infection, your small intestine may temporarily produce less lactase, the enzyme needed to digest milk sugar (lactose). This can cause or worsen symptoms like gas, bloating, and diarrhea, so it is best to avoid most dairy.

It is best to avoid caffeinated beverages like coffee and tea. Caffeine can act as a diuretic and stimulate your colon, which can increase dehydration and potentially worsen diarrhea.

The BRAT diet consists of bananas, rice, applesauce, and toast. These are bland, low-fiber foods that are easy on the stomach and can help bind stools. Many people find it helpful for easing back into eating after a stomach upset.

Fatty and fried foods are difficult for the body to digest, especially when your stomach is irritated. They can slow down gastric emptying and make nausea and bloating worse during your recovery.

Yes, even after initial symptoms pass, your stomach lining may still be sensitive. Spicy foods can irritate the healing lining and cause a return of symptoms like heartburn and discomfort. It is best to wait until you are fully recovered.

Some sports drinks can help with electrolytes, but many also contain high levels of sugar. Excessive sugar can worsen diarrhea. Oral rehydration solutions are a better choice, or you can dilute sugary drinks with water.

You should gradually reintroduce your normal diet as your symptoms improve. Start with small, frequent portions of bland foods and listen to your body. Most people can return to their regular diet within a week, but individual recovery times vary.
