Immune System and Its Importance
Before we start looking at the foods, we’ll just have a glance at our immune system. Your immune system is your body's natural defense mechanism against infections, diseases, and harmful pathogens such as bacteria, viruses, and toxins. It consists of a complex network of cells, tissues, and organs that work together to identify and neutralize foreign invaders. Key players in this system include white blood cells, antibodies, and various lymphatic organs like the spleen and lymph nodes. A strong immune system ensures that your body can fight off infections efficiently, while a weakened system leaves you vulnerable to illnesses. Maintaining a healthy immune system is vital for overall well-being, and one of the best ways to do this is through proper nutrition.
