The immune system is a network of cells, tissues and organs that work together to defend the body against bacteria, parasites and fungi, that can cause infections and diseases. If the immune system works properly, it recognizes the invaders and produces secretions and cells, in order to eliminate them and protect the body. Sometimes, the immune system overreacts or fights the wrong target, culminating in allergies or autoimmune diseases. A healthy immune system is the best protection against diseases.
Oxidation is an organic chemical process that can produce free radicals which could cause reactions and, possibly, diseases. Antioxidants prevent or minimize this damage. Antioxidants, like vitamins, minerals and flavonoids, are found in fruit, vegetables, herbal teas or supplements. They help to keep the body healthy and energetic.
