The Relation Between Green Tea Consumption and Psychological Distress


According to estimates from WHO, over 450 million people throughout the world suffer from stress. Stress could be the biggest health risk.

Previous studies have already shown that green tea and its extracts can have a positive impact on our health. In fact, studies have reported that the extracts may also help prevent Alzheimer’s and some kinds of cancer. In addition, they are said to improve cardiovascular and oral health as well as assist with weight management. (1)

 

Recent trials suggest that L-theanine, which is a constituent of green tea, reduces responses to acute psychological stress. Although green tea or its constituents might reduce psychological stress, the relation between green tea consumption and psychological distress has not been investigated in a large-scale study.

 

In 2009, a study was conducted to clarify whether green tea consumption is associated with lower psychological distress. Data for 42,093 Japanese individuals aged 40 from the general population were analyzed. Researches used multiple logistic regression analyses adjusted for age, sex, history of disease, body mass index, cigarette smoking, alcohol consumption, time spent walking, dietary factors, social support, and participation in community activities to investigate the relation between green tea consumption and psychological distress. They classified 2774 (6.6%) of the respondents as having psychological distress. There was an inverse association between green tea consumption and psychological distress in a model adjusted for age and sex. (2)

They found a statistically significant inverse relationship between the consumption of green tea and psychological distress for individuals who drank five cups or more of green tea each day; this is in comparison to individuals who only had one cup or less each day.

 

A recent study has shown that if you drink five cups of green tea each day, you may reduce occurrences of psychological distress by up to 20 percent. Further study will need to be done to clarify the bioactives and mechanisms in play. (1)
