In this video I will discuss
Green Tea, Stress and Depression
Although usually thought of as mere psychological states,
Stress and depression are actual physical changes in body chemistry
And they also have consequences,
For example,
Stress and depression cause memory loss
Memory impairment is frequently associated with old age or Alzheimer s disease
But as we will discuss,
there are other causes as well
In the case of stress and/or depression
The brain is notably affected
A class of hormones known as glucocorticoids
Are activated by both stress and depression
When secreted in excess, they cause imbalances in brain chemistry
That interfere with mood and memory
The effect is biochemical
Glucocorticoids disrupt serotonin, dopamine, norepinephrine and other brain chemicals
Here is where Theanine (just one active component in green tea) comes in
Theanine suppresses glucocorticoids
Theanine s connection to the suppression of glucocorticoids is through glutamate
Researchers have discovered that glutamate
Which is not traditionally associated with depression,
In fact plays a major role
In people who are depressed, glutamate levels are out of balance
Preliminary studies show that blocking certain glutamate activated signals in the brain
Are as effective as prescription antidepressants
Researchers believe that glutamate receptor antagonists
May offset the harmful effects of high glucocorticoid levels
L-theanine acts as a
glutamate receptor antagonist
In this manner, theanine may offer neuroprotective benefits against both
Acute stress and chronic depression
In summary,
Green tea can protect against the harmful consequences of stress and depression
Consequences like: memory loss, poor mood and increased suicide risk
