Dietary Considerations During Acute Gastroenteritis

Acute gastroenteritis, commonly referred to as stomach upset, is an inflammation of the gastrointestinal tract, affecting the stomach and intestines. Proper dietary management is crucial for recovery. The following information outlines foods that are generally poorly tolerated during an episode and should be avoided to minimize symptoms and promote healing.

Foods High in Fat

Fatty foods are difficult to digest and can exacerbate symptoms such as nausea, vomiting, and diarrhea. Avoid:

  • Fried foods
  • Fast foods
  • Processed snacks (e.g., chips, pastries)
  • High-fat meats (e.g., bacon, sausage)
  • Full-fat dairy products (e.g., whole milk, cheese, ice cream)

Sugary Foods and Beverages

High sugar intake can draw water into the intestines, worsening diarrhea. Avoid:

  • Sugary drinks (e.g., soda, juice, sports drinks)
  • Candy
  • Pastries
  • Processed foods with added sugars

Dairy Products (Generally)

Lactose intolerance can be triggered or worsened by gastroenteritis, making dairy consumption problematic. While yogurt with active cultures may sometimes be tolerated, other dairy products are best avoided initially. Specific considerations:

  • Lactose Intolerance: Gastroenteritis can temporarily reduce lactase production, leading to lactose intolerance.
  • Dairy Products to Avoid: Milk, cheese, ice cream, cream.
  • Yogurt with Active Cultures: May be tolerated in small amounts by some individuals due to probiotic benefits.

Spicy Foods

Spices can irritate the digestive tract and worsen symptoms. Avoid:

  • Hot peppers
  • Curries
  • Salsa
  • Other heavily spiced dishes

Caffeinated Beverages

Caffeine can stimulate the digestive system and increase dehydration. Avoid:

  • Coffee
  • Tea
  • Energy drinks
  • Chocolate

Alcohol

Alcohol can irritate the stomach lining and worsen dehydration. Avoid all alcoholic beverages.

Fiber-Rich Foods (Initially)

While fiber is generally healthy, large amounts of fiber can be difficult to digest during gastroenteritis and may worsen diarrhea. Limit intake initially. Examples:

  • Raw vegetables
  • Whole grains
  • Beans
  • Nuts and seeds

Considerations for Recovery

As symptoms subside, gradually reintroduce foods, starting with bland, easily digestible options such as the BRAT diet (bananas, rice, applesauce, toast). Pay attention to your body's signals and avoid foods that cause discomfort.
