Green Tea Preserves Memory

Modern science, ancient tea. They’re coming together today in ways worth paying attention to.

Whether you’re over 80, recently retired or related to somebody who is, new science shows green tea may hold the secret to a longer more satisfying life.

Most tea enthusiasts know green tea is good for you. What they may not know is that green tea may also prevent — or even reverse — the effects of Alzheimer’s and other dementia related diseases.

Researchers have long suspected the buildup of toxic proteins known as amyloid plaque is at least partly responsible for the pronounced cognitive decline experienced by one-in-three North American seniors today.

Now they’ve discovered green tea helps prevent amyloid plaque from developing in the first place. It can also break down existing plaque and help build important new brain cells known as neurons. In fact, clinical tests show drinking green tea can reduce the risk of developing dementia-like symptoms by up to 54 percent. Using advanced imaging technology, scientists have also demonstrated that green tea elevates brain activity in the regions directly associated with functioning memory.

The likelihood that contemporary science may be on the threshold of an amazing breakthrough is due, in large part, to the powerful green tea catechin known as epigallocatechin-3-gallate or EGCG. EGCG is one of nature’s most potent neuro-protective compounds as well as the most abundant polyphenol found in green tea leaves.

Matcha: The Greenest Green Tea

Matcha is a rich, high-quality, vibrant green tea grown and processed traditionally in Japan. One study suggests matcha contains 3 times more EGCG content than the largest “literature value” of other regular green teas. This is likely due to the fact matcha contains the entire tea leaf in powdered form, not just water infused through a tea bag or strainer.

Overall, green tea catechins have produced dramatic neuro-protective results in models of both Alzheimer’s and Parkinson’s diseases. In mammals, EGCG has been shown to reduce cognitive impairment along with what scientists call neuro-degeneration. It can scavenge oxygen-free radicals and reduce the inflammation common to many age-related afflictions.

The production of new brain neurons, or neurogenesis, is critical to brain function as we age and may serve as a new treatment strategy for a variety of dementia related disorders. Scientists have discovered that EGCG boosts the production of progenitors that transform into various types of neural cells.

Human vs. Animal Test Results

Lab tests on mice show EGCG elevates brain function by improving both object recognition and spatial memory. Remarkably, animal tests also show EGCG promotes new neurons in the same part of the brain where neurons die due to the onset of Alzheimer’s disease.

Could the same amazing results be demonstrated in humans? Four months of data collected from more than 1,000 Japanese volunteers aged 70 or more say yes! The Japanese data showed drinking two or more cups of green tea per day reduced the odds of cognitive impairment by 54% (over 4 times better than black tea or oolong tea).

Another study using neuroimaging to test healthy young adults showed green tea extract significantly boosts the level of activity in an area of the brain used to store information as well as to perform complex cognitive tasks like language and learning.
