There's a 'new' super food gaining popularity again that is over 3 billion years old. It does not get a lot of mention in the news these days as some of the other super foods like blueberries or the acai berry but it is one of the most nutrient dense foods available. It is one of the richest sources of vitamins, mineral and amino acids.

Here's some of its many health benefits:

* Strengthen the power of the immune system to fight disease

* Maintain healthy levels of cholesterol and improve the balance of good and bad cholesterol

* Support overall good cardiovascular function

* Improve the health of the gastrointestinal system

* Improve the natural detoxification and cleansing process of the body

* Provides strong antioxidant protection and anticancer benefits

It is rich in antioxidants called cartenoids, which are vital to cellular health. These antioxidants help rid your body of free radicals. This helps increase your longevity and helps you live a healthier life without experiencing many of the effects of aging such as wrinkles and darkened skin.

So what is it?

It's called Spirulina. It is a blue-green algae that is now being cultivated at special farms to keep it free of contaminants. It has been eaten for centuries and indigenous people have long known of the many health benefits imparted by this ancient algae.

Its ability to stimulate and enhance the immune system is one of the many reasons why it is increasing becoming one of the most researched foods in the world. It is thought that spirulina provides these immune system effects through the ability to bolster the natural killer cell functions of the body. Due to this mechanism it is thought that spirulina may be able to suppress both cancer and viral infections, and this is the subject of lots of research at the moment.

Some have even speculated that the higher spirulina consumption in Japan and Korea may be at least partially responsible for the lower incidence of HIV and AIDS in those countries. The speculation is that the immune boosting ability of this superfood may be able to fight this deadly infection.

As Spirulina research grows, look for more nutritional products containing extracts of this healthy super food.
