Groene thee verlaagt het slechte cholesterol

Research Question:
Drinking green tea lowers the cholesterol levels?

Study Design:
This overview article contained 14 Rcts with 1136 participants. The average follow-up period was 12 weeks (3 weeks to 3 months). The average dosage of green tea catechins was 625 mg per day (150-2500 mg per day).

There was no question of heterogeneity between the studies and publication bias.

Results and conclusions:
The researchers found that drinking green tea total cholesterol significantly with 7.20 mg/dL [95% CI =-8.19 to-6.21 mg/dL, p 0.001] reduced. Significant is, there is a link at a 95% reliability.

The researchers found that drinking green tea the LDL-cholesterol (bad cholesterol) significantly with 2.19 mg/dL [95% CI =-3.16 to-1.21 mg/dL, p 0.001] reduced.

The researchers found that drinking green tea the HDL-cholesterol (good cholesterol) non-significantly increased. Non-significant is, there is no link to a 95% reliability.

The researchers concluded that drinking green tea (with 625 mg of catechins per day) the bad cholesterol levels reduced.
