The Importance of Staying Hydrated
Staying hydrated is the most crucial aspect of recovery when you're sick. Fever, vomiting, and diarrhea can quickly lead to dehydration, which hinders your body's ability to fight off infection.
Key hydrating fluids:
- Water: The most effective way to stay hydrated.
- Clear broths and soups: Provide fluids, electrolytes, and warmth to soothe a sore throat and clear congestion.
- Herbal tea: Chamomile, ginger, and peppermint teas can be soothing and may help with nausea and congestion. A teaspoon of honey can also soothe a cough.
- Electrolyte drinks: If experiencing fever, vomiting, or diarrhea, sports drinks or oral rehydration solutions can help restore lost electrolytes and keep hydration balanced. However, watch out for high sugar content.
- Coconut water: A great natural source of electrolytes.
Best Foods for Colds and Flu
For respiratory illnesses like colds and the flu, focusing on foods that offer immune-boosting nutrients and anti-inflammatory properties can provide relief.
- Chicken Soup: A timeless remedy. The warm broth thins mucus, the steam helps open nasal passages, and the chicken provides protein for recovery.
- Garlic: Contains allicin, which has antiviral and antibacterial properties. Adding crushed garlic to your soup or meal can be beneficial.
- Ginger: Known for its anti-inflammatory effects and ability to soothe nausea and upset stomach. Brew it as a tea or add it to food.
- Honey: Coats the throat and can help reduce coughing, especially for adults and children over 12 months.
- Vitamin C-Rich Fruits: While it may not prevent a cold, regular intake can reduce the duration and severity of symptoms. Excellent sources include citrus fruits, kiwi, and berries.
- Yogurt: Plain yogurt with live and active cultures contains probiotics, which support gut health and, by extension, immune function.
- Green Leafy Vegetables: Spinach and kale are packed with vitamins A, C, E, and K, along with minerals that help fight inflammation.
What to Eat for an Upset Stomach
If you have a stomach bug with nausea, vomiting, or diarrhea, the focus shifts to bland, easy-to-digest foods to avoid further irritation.
The BRAT Diet and Beyond
The BRAT diet, consisting of bananas, rice, applesauce, and toast, is often recommended for settling a sensitive stomach. These low-fiber, bland carbohydrates provide energy without aggravating the digestive system.
- Bananas: Easy to digest and rich in potassium, an electrolyte often lost through vomiting or diarrhea.
- Plain Rice: Bland and easy on the stomach.
- Applesauce: A good source of carbohydrates and easily digestible pectin.
- Toast: Plain, dry toast is a simple carbohydrate that won't upset your stomach.
Other Bland Options
- Plain Potatoes: Mashed or boiled potatoes provide potassium and are gentle on the digestive tract.
- Plain Chicken or Turkey: Skinless, lean poultry is an excellent source of protein once you can tolerate more solid foods.
- Gelatin: Provides fluid and is very easy to digest, making it a good option in the early stages of a stomach bug.
Foods to Avoid When Sick
Just as some foods can help, others can worsen your symptoms. Knowing what to steer clear of is just as important as knowing what to eat.
Irritants and Dehydrators
- Sugary Foods and Drinks: Excess sugar can fuel inflammation and suppress the immune system. This includes most fruit juices with added sugar, soda, and candy.
- Alcohol and Caffeine: Both are diuretics that can lead to dehydration, disrupting sleep and slowing recovery.
- Greasy and Fried Foods: High-fat content can be difficult to digest and may worsen nausea, especially with a stomach bug.
- Spicy Foods: While they can clear sinuses for some, they can irritate a sore throat or trigger digestive issues in others.
- Hard or Crunchy Foods: Crackers, chips, and tough granola can be abrasive on a sensitive, sore throat.
- Processed Foods: Often low in nutrients and high in sodium and unhealthy fats, they offer little benefit to a recovering body.
- Full-Fat Dairy: Some people find dairy, especially full-fat varieties, can increase phlegm production or be hard to digest during illness, though this is not universally true.

Start with small, frequent servings of bland, easy-to-digest foods and prioritize hydration above all else. As you start to feel better, you can gradually introduce more nutrient-dense foods like fruits, vegetables, and lean proteins to rebuild your strength.
