Experiencing the flu often leaves the body weak, dehydrated, and low on energy. To recover faster, it’s important to focus on foods and drinks that strengthen the immune system while avoiding those that may worsen symptoms. Staying hydrated is essential, with water, broths, herbal teas, and juices without added sugars being the best options. Nutrient-rich foods such as chicken soup, vitamin C-packed fruits and vegetables, yogurt with probiotics, and anti-inflammatory spices like ginger and turmeric can support healing and boost immunity. On the other hand, alcohol, processed foods, fried meals, and sugary snacks should be avoided as they can strain digestion and prolong illness. Choosing the right diet can speed recovery and help the body fight infection.
Importance of hydration when you have the flu
Staying hydrated is one of the most critical steps in recovering from the flu. Fever, sweating, and reduced appetite can make dehydration more likely. Water remains the best option for hydration, but you can also include beverages that offer additional benefits:
- Warm broths (chicken, beef, or vegetable)
- Ginger tea for soothing nausea and inflammation
- Herbal teas with honey for throat comfort
- Lemon and honey tea for hydration and vitamin C
- 100% fruit juices without added sugar for fluids and nutrients
Low-sugar electrolyte drinks like Pedialyte can help restore electrolyte balance, especially in cases of vomiting or diarrhea, but should be used under a doctor’s supervision. Even fruits and vegetables contribute to hydration while providing vital nutrients.
