Immunity refers to the ability of the body to defend itself against harmful pathogens such as viruses, bacteria, and fungi. The immune system is a complex hub of cells, tissues, and organs that guards the body against infections and diseases and keeps you away from medical conditions. A healthy lifestyle that includes a well-balanced diet with immune boosting foods, regular exercise, adequate sleep, stress management, and avoiding tobacco and excessive alcohol consumption can help to support the immune system.
The immune system is divided into two main categories: innate immunity and adaptive immunity. Innate immunity is the first line of defence against pathogens. It includes physical and chemical barriers such as skin, mucous membranes, and stomach acid. It also includes white blood cells such as neutrophils, monocytes, and natural killer cells that can identify and destroy pathogens. Adaptive immunity, on the other hand, is a more specific and targeted response to pathogens. It involves the production of antibodies and activation of T cells and B cells that can recognise and destroy specific pathogens.
The immune system can be influenced by various factors such as age, genetics, lifestyle, and nutrition. In addition, vaccines can also help boost the immune system by exposing it to a weakened or inactivated form of a pathogen, which allows the body to build immunity against it.
Vitamins A, C, D, and E support the immune system. A lack of proper nutrition can make the immune system weak and the body susceptible to infections. Malnutrition can impair the immune system's ability to fight infections.
Therefore, it is important to consume a well-balanced diet that includes a variety of immune boosting foods such as vegetables, fruits, whole grains, healthy fats, and lean protein to keep the immune system healthy. In addition, maintaining a healthy lifestyle that includes regular exercise, adequate sleep, and stress management can also help to support the immune system.
