It’s not hard to understand the popularity of green tea and green tea pills when you start reading the positive studies. To add to the list, one of the many benefits of green tea includes keeping you sharp as you age.
Green tea can help slow the decline in brain function caused by age. It can help slow cognitive impairment, declining memory, dementia and even Alzheimer’s according to a study published by the American Journal of Clinical Nutrition in the February 2006 issue.
A study conducted at Japan’s Tohoku University including over 1000 participants over 70 years old showed the odds of cognitive impairment in elderly Japanese men and women decreased significantly in those who drank 2 or more cups of green tea a day.
From minimal to severe levels of cognitive impairment, the participants drinking the most green tea experienced less of a decline in mental ability than those drinking the least green tea.
According to this Japanese study the participants who drank 4-6 cups of green tea a week had a much lower risk of declining brain function.
They believe the powerful antioxidant known as EGCG is the largely responsible for these specific benefits of green tea because of the way it interacts with certain cell functions. ECGC helps prevent the formation of a protein known to cause Alzheimer’s; it helps protects brain cells by slowing the production of some damaging free radicals; it also helps encourage memory-related learning by protecting brain cells from free radical damage.
EGCG is one of the components that is a center of focus in the production of because it seems to be the main component providing many of the benefits of green tea. At least it’s the most powerful one we’re aware of at this point.
The more studies like this I discover the better I feel about my daily green tea habit.
