New Study Continues to Confirm that Green Tea Prevents Brain Decline

Study – Green Tea Effects 101

The Costly Price of Traumatic Brain Injuries on Society and our Loved Ones

For years, health experts have said there was a significant association between green tea and cognitive function. It was first noted in elderly Japanese and imported as a health fad. Many people believe that green tea consumption can help to improve cognitive function. And a new study that may finally confirm that tea intake, specifically green tea, can help to improve both cognitive decline and insulin resistance.

Ultimate Guide to Understanding Green Tea and Alzheimer Transgenic Mice

What makes green tea intake help cognitive impairment? A polyphenol known as epigallocatechin-3-gallate (EGCG).

The newest study was done on mice that were divided into three different groups.

  1. The first group, which was the control group, was not given any different dietary factors that could affect the outcome.

  2. The second group was given a high-fructose/high-fat diet

  3. Third group was given the same diet as the second, plus they were given a supplement of EGCG they’d get in a typical intake of green tea.

To measure memory decline, the mice were put into a water maze.

Green Tea Consumption Can Help Improve Cognitive Function

The mice in group three, the EGCG group, showed that they had a better memory of the maze than the mice in both the control group and in the second group. Researchers also found that EGCG was associated with a reduced risk of cognitive impairment and neurodegenerative diseases due to diet. In addition, the markers that researchers see in neural inflammation were also lower in the group given EGCG.

Fat People Eating Sugar Get More Brain Diseases?

Of course, green tea drinkers or not, fat people, especially with regular alcohol consumption, have reduced mental health. Lifestyle factors also show that fat people won’t take steps to improve cardiovascular health or other potential compounding factors.

This is important for people because the diet the mice were given, high fat and high fructose is a typical diet for 2/3 of US adults, many of which are obese. Obesity leads to increased inflammation, and that, in turn, can lead to everything from mild cognitive impairment to a higher risk of cognitive decline. There is even research that shows Alzheimer’s disease is more prevalent in those with poor dietary intake risk factors.

Because of all of this inflammation, it is possible that EGCG, found in green tea and green tea extract, can reduce these effects. When you look at tea consumption and cognitive impairment, or lack thereof, it can definitely help when giving yourself a mini mental state examination.

Catechins and Mild Cognitive Impairment?

Other studies show the effects of green tea are very positive overall for other bodily systems. For instance, green tea catechins are shown to help cardiovascular disease, and green tea polyphenols show great diverse health benefits, including the improvement of cognitive functions.

Females Benefit more From Polyphenols?

Yes. Based on a Food Frequency Questionnaire (FFQ) related to total polyphenol intake men don’t seem to benefit from polyphenols like women.

Here, participants of both sexes underwent a:

  1. Cognitive and Memory Function Test

  2. Assessment of Impulsivity

  3. Assessment of Dietary Habits.

The only improvement in cognitive function was among the female subjects. This disparity was noted in the disparity of the Montreal Cognitive Assessment (MoCA) score. The changes from initial start-up to follow-up between groups (p = 0.0103; +1.95 for the active group and +0.15 in the placebo). Particularly in the language domain covered in the MoCA score, a marked gain was discovered with female subjects, with no improvement in male participants.

Beyond this, many doctors and researchers caution against caffeine consumption. But red, green, and white tea do not have as much as black/oolong tea or other varieties of tea. However, all of these have some positive effects on the body, including improving human brain function. Green, not black tea, however, is the best for reducing amnestic, mild cognitive impairment.

If you don’t like the taste of tea, there are also supplements that contain EGCG, and it might be worth it to try for people who suffer from cognitive dysfunction, dementia, Alzheimer’s disease, mild age-related cognitive decline, and more. It is also recommended to eat a healthy diet that is low in refined carbs and sugar.

But keep getting exercise and improve your green tea intake, as that does the body good!
