Foods To Avoid When You Have Diarrhea: A Comprehensive Guide

Diarrhea can be an uncomfortable and disruptive experience. When you are dealing with diarrhea, choosing the right foods can significantly impact your recovery. FOODS.EDU.VN is here to guide you through the best dietary choices to make, explaining which foods to steer clear of to ease your symptoms and promote faster healing. Identifying trigger foods, like those high in lactose or artificial sweeteners, is vital in managing digestive distress and discomfort.

1. Dairy Products: A Potential Irritant

Many people find that dairy products exacerbate diarrhea symptoms. Even if you are not typically lactose intolerant, your body might struggle to digest dairy when you have diarrhea.

Why Dairy Can Be Problematic

Dairy contains lactose, a sugar that requires the enzyme lactase for digestion. Diarrhea can reduce lactase levels in your body, making it difficult to process lactose. This can lead to worsened diarrhea, gas, bloating, and nausea. According to the National Institute of Diabetes and Digestive and Kidney Diseases, lactose intolerance can be a temporary condition following a bout of diarrhea.

Dairy Foods to Avoid

Milk (cow, goat, buffalo)
Cheese (especially soft varieties like brie and cream cheese)
Ice cream and frozen yogurt
Cream and whipped cream
Sour cream
Butter
Buttermilk
Whole-milk yogurt
Powdered milk

Always read food labels carefully, as lactose can be a hidden ingredient in processed foods, including baked goods, meats, cereals, and snacks.

Dairy Alternatives to Consider

Fortunately, many delicious and nutritious dairy alternatives are available:

Almond milk: Low in calories and lactose-free.
Soy milk: A good source of protein and lactose-free.
Cashew milk: Creamy and lactose-free.
Oat milk: High in fiber and lactose-free.
Rice milk: A mild-flavored, lactose-free option.
Non-dairy sorbets: A refreshing, dairy-free dessert.
Coconut milk ice cream and yogurt: Creamy and lactose-free.
Powdered, non-sweetened non-dairy creamer: A convenient option for coffee or tea.

Switching to these alternatives can provide essential nutrients without the digestive upset associated with dairy.

The Exception: Yogurt

Non-fat yogurt is often recommended for managing diarrhea, provided you are not lactose intolerant or allergic to milk proteins. Yogurt contains probiotics, beneficial bacteria that can help restore balance to your intestinal flora and alleviate diarrhea. Look for yogurts that are low in sugar and contain Lactobacillus probiotic strains.

If dairy yogurt is not an option, consider dairy-free yogurt or probiotic supplements.

2. Fatty Foods: A Digestive Challenge

Fatty foods can be difficult to digest even under normal circumstances, but diarrhea exacerbates this issue. Poor fat absorption leads to fatty acids accumulating in the colon, which triggers fluid secretion and increases intestinal contractions (peristalsis), ultimately worsening diarrhea.

Fatty Foods to Avoid

Fried foods: Potato chips, French fries, onion rings, doughnuts.
Fatty meats: Hamburgers, pork butt, fatty cuts of beef or lamb.
Processed meats: Hot dogs, sausages, bacon, salami.
Fast foods: Burgers, pizzas, nachos, fried chicken.
Baked goods: Pies, cakes, pastries.
Chicken skin
Ghee and lard
Coconut and palm oil
Cream soups
Gravy

Better Protein Choices

While recovering from diarrhea, focus on lean protein sources:

Skinless chicken
Fish
Lean cuts of pork or beef
Eggs

Bananas and avocados are also beneficial, as bananas can help bind watery stools.

3. Sugar-Free Foods: A Sweet Deception

Artificial sweeteners, especially sugar alcohols, can have a laxative effect. These sugar alcohols, including sorbitol, xylitol, lactitol, erythritol, mannitol, and maltitol, can also increase gas and bloating.

Sugar-Free Items to Avoid

Diet sodas
Sugar-free drinks (including energy drinks)
Sugar-free candy
Coffee sweeteners like Equal (aspartame) and Sweet-and-Lo (saccharin)

Better Beverage Options

Opt for water or lightly sweetened tea (herbal or decaf) instead. A small amount of sugary candy might be acceptable if you have cravings, but moderation is key.

Stevia: A Safer Sweetener?

Stevia, a plant-based, zero-calorie sweetener, is generally considered safe and is not known to cause gastrointestinal issues. However, some stevia blends contain sugar alcohols, so always check the product label.

4. Gas-Producing Foods: Triggering Discomfort

Certain fruits, vegetables, and legumes can cause gas, which can worsen diarrhea, particularly for those with digestive conditions. Beans are especially problematic due to their high fiber content, which, while usually beneficial, can exacerbate diarrhea symptoms.

Gassy Foods to Avoid

Navy beans
Pinto beans
Black beans
Lima beans
Black-eyed peas
Chickpeas
Soybeans
Miso
Asparagus
Broccoli
Cabbage
Cauliflower
Brussels sprouts
Onions
Peaches
Pears
Plums
Apricots
Mangos
Dried fruits

Gentle Food Choices

Better choices include:

Spinach
Green beans
Zucchini
Blueberries
Strawberries
Honeydew
Cantaloupe

Lentils are less likely to cause gas than other beans. Other good options include starchy vegetables, leafy greens, zucchini, bell pepper, melons, kiwi, and berries (in moderation).

5. Acidic or Spicy Foods: Irritating the Gut

Acidic and spicy foods can irritate the lining of the stomach and intestines, increasing intestinal contractions to expel the irritants. Capsaicin, found in chili peppers, is a well-known trigger. While you might tolerate these foods under normal circumstances, your intestine may be more sensitive when you have diarrhea.

Acidic and Spicy Foods to Avoid

Tomato sauce
Tomato juice and vegetable juices
Citrus fruits
Garlic
Onions
Salsa
Chili and curries
Hot sauces
Horseradish
Mustards
Wasabi
Jalapeños

Flavorful Alternatives

If you crave strong flavors, consider using cinnamon and ginger in moderation. These spices can help ease stomach discomfort and add flavor to food without causing irritation.

6. Caffeine: A Stimulant to Avoid

Caffeine is a stimulant that increases peristalsis, acting as a laxative and worsening diarrhea. It is also a diuretic, contributing to dehydration, which can be a significant concern when you have diarrhea. According to Mayo Clinic, excessive caffeine intake can stimulate the digestive system and lead to increased bowel movements.

Caffeinated Beverages to Avoid

Black tea
Chocolate (including hot chocolate and cocoa)
Coffee
Energy drinks
Oolong tea
Orange pekoe tea
Pu-erh tea

:max_bytes(150000):strip_icc()/caffeine-56a08e895f9b58eba4b1885b.jpg)

7. Alcohol: An Irritating Substance

Alcohol can irritate the stomach lining and intestines, increasing gut motility. Beer and wine are also high in carbohydrates, which can be difficult to break down when you have diarrhea.

Alcoholic Beverages to Avoid

Beer (including non-alcoholic beer)
Wine (including low-alcohol wine)
Liquor and spirits
Hard cider

:max_bytes(150000):strip_icc()/GettyImages-1044350714-51702bab905f47f983bce531ada3449f.jpg)

8. Carbonated Drinks: Bubbling Trouble

Carbonated beverages are generally not recommended when you have diarrhea. The carbon dioxide gas in these drinks can cause gas and bloating. Research indicates that carbon dioxide dissolves in the stomach, and as the gas is released, it can lead to burping.

Carbonated drinks containing sugar, high fructose corn syrup, or artificial sweeteners can further exacerbate diarrhea and should be avoided.

Hydrating Alternatives

Instead of soda, caffeinated drinks, or alcohol, choose:

Caffeine-free herbal teas (chamomile, fennel, peppermint)
Hydrating drinks like Pedialyte
Water

9. High-FODMAP Foods: A Focus for IBS Sufferers

If you experience diarrhea due to irritable bowel syndrome (IBS), you might benefit from avoiding high-FODMAP foods. FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) are types of carbohydrates that can trigger IBS symptoms. Studies published in the Journal of Gastroenterology and Hepatology have shown that a low-FODMAP diet can significantly reduce IBS symptoms.

High-FODMAP Foods to Limit

Garlic, onions, and legumes
Apples, mangos, peaches, and cherries
Most dairy products
Honey, agave nectar, high-fructose corn syrup
Almonds, cashews, hazelnuts, and pistachios
Wheat, rye, barley, and couscous

Low-FODMAP Choices

You may feel better by choosing low-FODMAP foods:

Eggs and meat
Almond milk
Rice, oats, and quinoa
Potatoes, cucumbers, zucchini
Grapes, strawberries, blueberries

10. Understanding the BRAT Diet

The BRAT diet (Bananas, Rice, Applesauce, Toast) is often recommended for people with diarrhea. These foods are easy to digest, low in fiber, and can help to firm up stool. However, it’s important to note that the BRAT diet is not nutritionally complete and should only be followed for a short period. The Cleveland Clinic recommends reintroducing other foods as soon as you can tolerate them.

Benefits of BRAT Diet Foods

Bananas: Provide potassium and help bind stools.
Rice: Easily digestible and provides energy.
Applesauce: Gentle on the stomach and provides some nutrients.
Toast: Simple and easy to digest.

Limitations of the BRAT Diet

Lacks essential nutrients: It is not a long-term solution.
May lead to constipation: Due to low fiber content.
Not suitable for everyone: Consult a healthcare provider for personalized advice.

11. Probiotics: Restoring Gut Balance

Probiotics are beneficial bacteria that can help restore the balance of your gut flora. They can be particularly helpful in cases of diarrhea caused by infections or antibiotics. According to the World Gastroenterology Organisation, probiotics can shorten the duration of diarrhea and reduce its severity.

Sources of Probiotics

Yogurt: Look for live and active cultures.
Kefir: A fermented milk drink.
Sauerkraut: Fermented cabbage.
Kimchi: A Korean fermented dish.
Probiotic supplements: Available in capsule or powder form.

Choosing the Right Probiotic

Strain specificity: Different strains of probiotics have different effects. Look for strains like Lactobacillus and Bifidobacterium.
CFU count: Colony Forming Units (CFU) indicate the number of live bacteria. A higher CFU count is generally better.
Consultation: Talk to a healthcare provider to determine the best probiotic for your specific needs.

12. Staying Hydrated: A Crucial Step

Diarrhea can lead to significant fluid loss, increasing the risk of dehydration. Replenishing fluids is essential for recovery. The National Academies of Sciences, Engineering, and Medicine recommends that men consume about 15.5 cups (3.7 liters) of fluids per day, and women consume about 11.5 cups (2.7 liters) per day.

Best Hydrating Fluids

Water: The simplest and most effective option.
Oral rehydration solutions (ORS): Contain electrolytes to help replace lost minerals.
Clear broths: Provide sodium and fluids.
Herbal teas: Chamomile, ginger, and peppermint teas can soothe the stomach.
Coconut water: A natural source of electrolytes.

Signs of Dehydration

Increased thirst
Dry mouth
Dark urine
Dizziness
Fatigue

If you experience these symptoms, it’s important to increase your fluid intake and seek medical attention if necessary.

13. Foods That Can Help Ease Diarrhea

Besides avoiding certain foods, incorporating specific items into your diet can help ease diarrhea symptoms:

Bananas: Rich in potassium and help bind stools.
Rice: Easily digestible and provides energy.
Applesauce: Gentle on the stomach and provides some nutrients.
Toast: Simple and easy to digest.
Boiled potatoes: Provide potassium and are easy to digest.
Chicken broth: Provides electrolytes and fluids.

These foods are part of the BRAT diet, which is often recommended for diarrhea.

14. Fiber Intake: Balancing Act

While fiber is generally beneficial for digestive health, it can exacerbate diarrhea symptoms. Soluble fiber can help absorb water in the gut, while insoluble fiber can add bulk to the stool. During a bout of diarrhea, it’s best to focus on soluble fiber sources. According to the Academy of Nutrition and Dietetics, soluble fiber can help regulate bowel movements.

Soluble Fiber Sources

Oatmeal
Bananas
Applesauce
Pears
Cooked vegetables

Insoluble Fiber to Limit

Whole wheat products
Nuts
Seeds
Raw vegetables

15. The Importance of Small, Frequent Meals

Eating large meals can overwhelm your digestive system when you have diarrhea. Opt for small, frequent meals to ease digestion and prevent exacerbating symptoms. The National Health Service (NHS) recommends eating small, frequent meals rather than large ones to help manage digestive issues.

Benefits of Small Meals

Easier digestion
Consistent energy levels
Reduced strain on the digestive system
Better nutrient absorption

Sample Meal Plan

Breakfast: Oatmeal with banana slices
Mid-morning snack: Applesauce
Lunch: Boiled chicken and rice
Afternoon snack: Toast with a small amount of honey
Dinner: Baked fish with boiled potatoes

16. Lifestyle Adjustments to Support Recovery

In addition to dietary changes, several lifestyle adjustments can help support your recovery from diarrhea:

Rest: Allow your body to recover.
Avoid strenuous activity: Restrict physical activity until symptoms improve.
Practice good hygiene: Wash your hands frequently to prevent the spread of infection.
Manage stress: Stress can exacerbate digestive symptoms.
Avoid smoking: Smoking can irritate the digestive system.

17. Consulting a Healthcare Professional

While dietary and lifestyle changes can often help manage diarrhea, it’s important to consult a healthcare professional if:

Diarrhea lasts more than a few days
You experience severe dehydration
You have blood in your stool
You have a fever
You experience severe abdominal pain

A healthcare professional can help determine the cause of your diarrhea and recommend appropriate treatment.

18. The Role of Digestive Enzymes

Digestive enzymes help break down food into smaller, more easily absorbed molecules. If you have difficulty digesting certain foods, digestive enzyme supplements may be helpful. According to the National Center for Complementary and Integrative Health, digestive enzymes can improve digestion and reduce symptoms like bloating and gas.

Types of Digestive Enzymes

Amylase: Breaks down carbohydrates.
Protease: Breaks down proteins.
Lipase: Breaks down fats.
Lactase: Breaks down lactose.

Consulting a Healthcare Provider

Before taking digestive enzyme supplements, it’s important to consult a healthcare provider to determine the appropriate dosage and type of enzyme.

19. Keeping a Food Diary

Keeping a food diary can help you identify specific foods that trigger your diarrhea. Record everything you eat and drink, as well as any symptoms you experience. Over time, you may notice patterns that help you identify trigger foods.

Benefits of a Food Diary

Identify trigger foods
Track symptoms
Monitor progress
Provide information for healthcare providers

Tips for Keeping a Food Diary

Be detailed: Record everything you eat and drink.
Be consistent: Record your meals and symptoms every day.
Be honest: Don’t leave out any information.
