Best foods and drinks to boost your immune system this flu season

Key Points:

• Experts emphasize the importance of supporting the immune system during flu season by consuming a balanced diet rich in nutrient-dense foods, particularly those that promote gut health such as fiber and fermented foods.
• Vitamin C-rich colorful fruits and vegetables, fermented foods like yogurt and sauerkraut, and fiber sources including beans, nuts, and seeds are recommended to enhance immune function and gut microbiome balance.
• Protein and zinc are vital for building immune cells, with lean meats, shellfish, eggs, pumpkin seeds, and chickpeas highlighted as good sources; dairy milk is also noted for its immune-supporting vitamins and hydration benefits.
• Contrary to common belief, milk does not increase mucus production, though it may cause a sensation of thickness in the throat; lactose-intolerant individuals can opt for lactose-free milk to obtain similar nutrients.
• Maintaining hydration, adequate sleep, stress management, physical activity, and cautious use of supplements under healthcare guidance are also key factors in supporting a healthy immune system during flu season.
