Groene thee verlaagt de bloeddruk en het cholesterolgehalte

Research Question:
Although earlier literature shows that a regular consumption of green tea improves blood pressure, the evidence from scientific studies are not consistent. It was therefore carried out this review article.

Drinking green tea lowers blood pressure and cholesterol levels?

Study Design:
This overview article contained 13 Rcts.

Results and conclusions:
The researchers found that drinking green tea the systolic blood pressure (systolic blood pressure) significantly with 2.08 mmHg [95% CI =-3.06 to-1.05] reduced.

The researchers found that drinking green tea the diastolic blood pressure (underpressure) significantly with 1.71 mmHg [95% CI =-2.86 to-0.56] reduced.

The researchers found that drinking green tea total cholesterol significantly with 0.15 mmol/L [95% CI =-0.27 to-0.02] reduced.

The researchers found that drinking green tea the LDL cholesterol (the bad cholesterol) significantly with 0.16 mmol/L [95% CI =-0.22 to-0.09] reduced.

The researchers found in the subgroup analyses (to get more information) a larger reduction in systolic and diastolic blood pressure in participants with an average baseline systolic blood pressure of ≥ 130 mmHg and in studies where green tea as extract was given.

The researchers concluded that drinking green tea (especially if extract or green tea catecinen) the blood pressure and cholesterol levels (especially in people with elevated blood pressure) reduced.
