The Importance of Nutrition During a Viral Illness

When fighting a viral infection, proper nutrition and hydration are vital for supporting your immune system and recovery. Symptoms like fever, vomiting, and diarrhea can increase nutrient and fluid loss, making it crucial to replenish your body's resources. A balanced diet provides the necessary fuel to fight off the infection, while a poor diet can potentially weaken your defenses and prolong the illness.

The Golden Rule: Prioritize Hydration

Staying hydrated is paramount when you're sick. Fever, sweating, vomiting, and diarrhea all contribute to fluid loss and electrolyte depletion. Key hydrating fluids include water, broths and soups, coconut water, and herbal teas. {Link: unitypoint.org https://www.unitypoint.org/news-and-articles/food-and-drink-to-help-you-fight-the-flu}.
