Foods That Help Diarrhea & The BRAT Diet: A Dietitian's View
Diarrhea is a digestive issue everyone faces at some point. It can suddenly lower your quality of life and leave you feeling weak. As a Registered Dietitian, I understand your anxiety about, "What can I eat that won't make it worse?"
In this guide, we'll walk through science-backed nutrition strategies to soothe your stomach, replace lost nutrients (electrolytes), and reduce trips to the bathroom, focusing on the well-known BRAT Diet.
First and Most Important Step for Diarrhea: Fluids and Electrolytes
The biggest danger of diarrhea is dehydration—the excessive loss of fluids and minerals from your body. The goal isn't just to drink water, but also to replace vital minerals like sodium and potassium.
Homemade Life-Saving Fluid (ORS) Recipe
Here is a "serum-like" mixture recommended by the World Health Organization (WHO) that you can make at home when you can't get to a pharmacy:
🥤 Homemade Oral Rehydration Solution (ORS)
- 1 liter of boiled and cooled clean water
- 6 teaspoons of sugar (Essential for glucose absorption)
- Half a teaspoon of salt
Mix all ingredients and sip it throughout the day. This mixture enhances your intestine's ability to absorb water.

In nutrition, the first protocol that comes to mind for diarrhea is the BRAT diet. It's an acronym for four basic foods that are easy on the stomach and help firm up your stool:
- B - Banana: A great source of potassium, it helps replace lost energy.
- R - Rice: White rice porridge is one of the easiest carbohydrates to digest.
- A - Applesauce: Cooked, unsweetened applesauce (without the peel) contains pectin, which helps bind the stool.
- T - Toast: Plain white bread or toast can help absorb stomach acid.
What to Eat and Avoid for Diarrhea (Quick Checklist)
You can quickly check which foods are your friends and which are your foes from the table below:
| ✅ FOODS THAT HELP DIARRHEA (Eat These) | ❌ FOODS THAT WORSEN DIARRHEA (Avoid These) |
|---|---|
| Boiled Potatoes (Peeled) | Milk and Creamy Products (Lactose) |
| Plain Rice Porridge / Pasta | Greasy and Fried Foods |
| Yogurt and Kefir (Probiotics) | Sugary Fruit Juices / Soda |
| Saltine Crackers / Pretzels | Legumes (Beans, Lentils - cause gas) |
| Boiled Chicken Breast (Skinless) | Coffee and Strong Tea (Caffeine) |
The Biggest Mistakes People Make During Diarrhea
- Drinking Milk: During diarrhea, your intestines temporarily lose the ability to digest lactose. Drinking milk can worsen gas and diarrhea.
- Drinking Cola/Soda: While a common folk remedy, the high sugar content can draw more water into your intestines, worsening diarrhea (Osmotic Diarrhea).
- Eating Too Much Fiber: Foods like bulgur, whole wheat bread, or raw vegetables speed up bowel movements. You should opt for white bread and cooked vegetables instead.
When to See a Doctor (Red Flags)
Nutritional measures should provide some relief within 24 hours. However, you should seek immediate medical attention in the following situations:
- If there is blood or pus in your stool,
- If you have a fever over 101.3°F (38.5°C),
- If you have severe abdominal pain that doesn't go away,
- If diarrhea lasts longer than 2 days (48 hours).

Diarrhea is one of your body's defense mechanisms (to expel toxins). Instead of stopping it immediately with medication, the healthiest approach is to support your body with the right nutrition. If you experience diarrhea frequently, it could be a sign of an underlying issue like IBS or a food intolerance.
