When it comes to staying healthy and fighting off illnesses, your immune system plays a crucial role. The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful invaders like bacteria, viruses, and other pathogens. And one key factor that can impact the strength of your immune system is nutrition.
What you eat directly affects how well your immune system functions. A diet rich in essential nutrients can help support a strong immune response, while a diet high in processed foods and sugar can weaken your body’s defenses. In this article, we’ll explore the role of nutrition in immune health and discuss some of the top foods that can boost your body’s defenses.
