Green Tea with red light may help fight Alzheimer's disease, study finds!

The same group of researchers have earlier used red light to introduce cancer drugs into cells. The laser light was found to displace water out of the cells and when the light is turned off, the cells take in water and any other molecules, including drugs, from their surroundings.

They have now found that the same technique can be used to destroy the beta-amyloid plaques that contribute to the development of Alzheimer's Disease.

The team immersed brain cells containing beta-amyloid in epigallocatechin gallate (EGCG) - an antioxidant catechin found in great concentrations in green tea - while at the same time stimulating the cells with red light. The result was that beta-amyloid in the cells fell by around 60%. Applying the laser light alone onto the cells reduced beta-amyloid by around 20%.

The leaf bud and the first leaves of the camellia sinensis tea plant contain the most abundant amounts of EGCG. Green tea and white tea have lots of EGCG content as these types undergo the least oxidation. Experiments conducted on animals have found that when the green tea is fed orally and then exposed to the red laser light, the EGCG was transported through the laser and are capable of reaching the bones and tissue. This process may then help activate mitochondria and thus strengthen the permeability of the blood-brain barrier. This makes it possible for the brain to absorb the beneficial ingredients of the EGCG. The scientists were of the opinion that there is no other reason why other drugs that attack beta-amyloid could not be delivered to the brain in the same way. "This important research could form the basis of a potential treatment for Alzheimer's, with or without complementary drug treatment," says Mario Trelles, medical director of the Vilafortuny Medical Institute in Cambrils , Spain . "The technique described could help to regulate and even stop the appearance of this disease," he adds.

Did you know that:

• EGCG or epigallocatechin gallate is the most abundant antioxidant catechin in green tea.

'Superfood' is the term used to describe foods with high antioxidant and phytonutrient content. Go here to find a list of 'superfoods'.

• Vitamin C is said to help the body absorb more of the antioxidant content of green tea. New studies have shown that taking citrus juices, like those of oranges and lemons, along with green tea enable more of the tea's antioxidants to remain after the digestion process is completed.

• Antioxidants in green tea help fight the ravages of free radicals that are seen as the source of many of today's debilitating diseases. Did you know that aside from the catechins that are so abundant in green tea, there are many other types of antioxidants? Discover them all here.

Could any two beverages be any more different? Discover what makes red wine a healthy drink when taken in moderation here.

• The quality of the water used to brew the tea is very important. It is believed that the water used must be free of contaminants and contain enough oxygen to enhance the natural flavor of the tea. Teas made with pure water yield a crisp flavor and a clear brew that is aesthetically pleasant. Learn more about the health benefits of water here.
