When you’re battling a fever, your body is already working overtime to fight off infection and heal itself. What you eat during this time can either support your recovery — or make things worse. While some foods nourish your immune system and keep you hydrated, others can increase inflammation, cause digestive trouble, and slow down your healing.
It’s not just about eating healthy — it’s about knowing what to avoid too. In this guide, we’ll walk you through 10 common foods that you should steer clear of when you have a fever, and explain why they could be secretly holding you back from getting better. Let’s dive in and help your body heal faster, naturally!
10 Foods to Avoid During Fever & What to Eat Instead
If you want to get better faster, avoid these foods during a fever:
1. Fried and Fatty Foods
Fried chicken, burgers, samosas, pakoras — they’re delicious, but very hard to digest during a fever.
Why avoid them?
- They are heavy on your digestive system.
- They slow down metabolism, making you feel more tired.
- High-fat foods increase inflammation in the body.
Tip: Stick to light, steamed, or boiled foods like khichdi, boiled rice, or plain toast.
2. Sugary Foods and Sweets
Chocolates, cakes, candies, sweetened drinks — these can be dangerous for your recovery.
Why avoid them?
- Excess sugar suppresses white blood cell activity (your body’s defenders).
- Sugar feeds harmful bacteria and viruses.
- It promotes inflammation, worsening your fever symptoms.
Tip: If you crave something sweet, eat fruits like bananas or apples instead.
3. Dairy Products (Especially Full-Fat Milk and Cheese)
Milkshakes, cheese-loaded foods, and creamy desserts are best avoided, especially if you have a cold or cough along with fever.
Why avoid them?
- Dairy can thicken mucus, making congestion worse.
- It can make throat infections feel heavier.
Tip: Yogurt (plain, unsweetened) is a better alternative because it contains probiotics that can support your immune system.
4. Spicy and Strongly Seasoned Foods
Hot sauces, chilies, heavy curries — all these can cause more trouble than comfort.
Why avoid them?
- Spices can irritate the throat and stomach lining.
- They can trigger acid reflux and worsen dehydration.
Tip: Go for mildly seasoned foods like vegetable soup, dal, or boiled potatoes.
5. Caffeinated Beverages
Coffee, black tea, energy drinks — although you might think they’ll boost your energy, they’re actually harmful during fever.
Why avoid them?
- Caffeine is dehydrating.
- It can interfere with your sleep cycle, and rest is crucial during fever.
Tip: Herbal teas like chamomile or ginger tea can soothe your body and promote healing.
6. Processed and Packaged Foods
Instant noodles, chips, ready meals, frozen pizzas — convenient but not suitable during illness.
Why avoid them?
- They contain excess salt, sugar, and preservatives.
- They put stress on your digestive system and liver.
Tip: Freshly prepared homemade food is your best friend during recovery.
7. Carbonated and Sugary Drinks
Sodas, colas, and even packaged fruit juices are high in sugar and artificial additives.
Why avoid them?
- They cause bloating and upset your stomach.
- High sugar content worsens inflammation.
Tip: Drink plain water, coconut water, or homemade lemon water to stay hydrated.
8. Red Meat
Beef, lamb, pork — heavy meats are tough on your body when it’s already under stress.
Why avoid them?
- Red meat is harder to digest.
- It increases body temperature and can prolong inflammation.
Tip: Choose lighter protein sources like lentils, boiled eggs, or fish (if tolerated).
9. Alcohol
A glass of wine might seem harmless, but during a fever, it’s extremely risky.
Why avoid it?
- Alcohol severely dehydrates your body.
- It weakens your immune system.
- It can interact dangerously with any medication you’re taking.
Tip: Stick to water, electrolyte-rich fluids, or warm herbal teas.
10. High-Fiber Raw Vegetables
Salads loaded with raw cabbage, broccoli, or kale may sound healthy, but during a fever, your digestive system may struggle.
Why avoid them?
- Raw, fibrous vegetables can cause gas, bloating, and stomach cramps.
- Fever often weakens digestion temporarily.
Tip: Lightly cooked or steamed vegetables are easier to digest and just as nutritious.
Bonus: Quick “Do’s” During Fever Recovery
- Drink plenty of fluids — water, herbal teas, electrolyte drinks.
- Eat small, frequent, light meals.
- Choose foods rich in vitamin C (like oranges, kiwi, amla) to boost immunity.
- Rest as much as possible — don’t rush your recovery!
