The immune system protects the body from attack by microorganisms, abnormal cells and chemicals. Its army includes macrophages, T cells and B cells. Most often the external threats are infections caused by invading bacteria, viruses, and fungi, while abnormal or cancerous cells pose the major internal threats. In addition, this complex system oversees the repair of tissues that are injured by wounds or disease.
Once in a while the immune system mistakes a harmless foreign substance for an enemy, resulting in an allergic reaction, such as hives, hay fever or asthma. Less commonly the immune system mistaking an internal signal attacks normal body tissue, leading to an autoimmune disease, such as type 1 diabetes, rheumatoid arthritis, or lupus.
The most remarkable characteristic of immune system is its “memory” for foreign substances and organisms. Confronted with a virus or other invading organism, the system creates an antibody that will recognize it and mount an attack against it at any future encounter. This mechanism called acquired immunity is what makes vaccinations to work.
Why immune system get failure?
There is a lapse between the time an invading organism enters the body and the time the immune system conquers it. In the interim the invader can its mark, killing cells. How sick you depends largely on how strong a defense your immune system can launch. Infection, cancer and other illnesses develop when the immune system is weakened by any number of stressors, including viruses and other invading organisms, malnutrition and the consequences of ageing. Fortunately antibiotics and sulfa drugs can wipe out most bacterial infections in otherwise healthy people; progress is also made in the development of anti viral drugs. At times doctors purposely lower immunity to treat an autoimmune disease or to prevent rejection of donor organs.

Dietary influence
The right diet is critical to a strong immune system. The following are the building blocks you need to keep your defenses strong. Its best to get them from food. Supplements are usually not necessary unless you are taking therapeutic doses for a specific condition.
1. Garlic and Onions
2. Moderate exercise
3. Shiitake mushrooms
4. Fermented milk products (Yogurt and Kefir)
5. Blueberries, Blackberries and Grapes

- Proteins are central to the proper functioning of the immune system
- Omega-3 and Omegea-6 fatty acids help in immune function
- Vitamin E is a T cell enhancer
- Vitamin C to fortify
- Vitamin A is Key for immune system
- Zinc is trace mineral with many important functions, including supporting immunity
- Selenium is a trace mineral essential for a strong immune system
- Iron is an absolute must
- Antioxidants to protect against free radicals
