In today’s fast-paced world, maintaining a strong immune system is more important than ever. Your immune system plays a crucial role in defending your body against harmful pathogens, viruses, and bacteria. While factors like genetics and lifestyle choices can influence your immune health, one of the most effective ways to boost your immunity is through a healthy diet. By incorporating nutrient-dense foods into your daily meals, you can provide your body with the essential vitamins, minerals, and antioxidants it needs to function optimally.
The Role of Diet in Immune Health
