The immune system is vital to our well-being. It is designed to indentify invaders and destroy them. This includes defective body cells as well as bacteria and viruses. In addition to this the immune system controls the inflammatory process, protecting us from infection and disease.
The main entrance into the body is via the digestive tract and lungs. Within the digestrive tract is the "gut associated" immune system which is designed to allow completely digested food particles to pass un-hindered through the gut wall into the body. Incompletely digested food can result in immune reactions and eventually allergies.
The nasal passages help prevent unwanted agents entering the lungs. Healthy, strong mucous membranes in the respiratory and digestive tracts are the first line of defence against invaders.
Immune strength is dependent on optimal intake of vitamins and minerals. Deficiencies of Vitamins A, B, C and E suppress immunity as do deficiencies in essential fats, probiotics, anti-oxidants, iron, zinc, magnesium and selenium. Protein is also essential to provide new immune cells.
Eating foods such as sardines, salmon, cod, chicken, nuts and seeds, green leafy vegetables, beans, pulses and fresh fruit will help provide the nutrients necessary to help boost your immune system.
