    New Study Continues to Confirm that Green Tea Prevents Brain Decline

Study – Green Tea Effects 101

Ultimate Guide to Understanding Green Tea and Alzheimer Transgenic Mice

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 may finally confirm that tea intake, specifically green tea, can help to improve both cognitive decline and insulin resistance.

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

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

  1. The first group, 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. The 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 a better brain memory of the maze than the mice in both the control group and the second group. Researchers also found that diet-associated EGCG was associated with a reduced risk of cognitive impairment and neurodegenerative diseases. 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 those 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, which can lead to everything from mild cognitive impairment to a higher risk of cognitive decline. Even research shows that 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 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 help cardiovascular disease, and green tea polyphenols show diverse health benefits, including improving 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 for 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. However, green, not black tea, is the best for reducing amnestic, mild cognitive impairment.

Suppose you don’t like the taste of tea. In that case, there are also supplements containing EGCG, and it might be worth trying 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.
