Voedingsadvies El MondoResearch Question:
The effect of green tea catechins with or without caffeine on the glycemic control is contentious and therefore was carried out this review article.
Drinking green tea improves the glycemic control?
Study Design:
This overview article contained 22 Rcts with 1584 participants. There was found no heterogeneity for the insulin levels, blood glucose levels, the sober sober the HbA1c value or the HOMA-IR-value.
Results and conclusions:
The researchers found that drinking green tea catechins with or without caffeine the sober blood sugar significantly with 1.48 mg/dL [95% CI =-2.57 to-0.40 mg/dL] reduced. Significant is, there is a link at a 95% reliability. The lowering effect on the empty blood sugar was found after 12 weeks.
The researchers found that drinking green tea catechins with or without caffeine the sober insulin levels non-significant with 0.04 μU/mL [95% CI 0.36 to 0.45 μU/mL = −] increased. Non-significant is, there is no link to a 95% reliability.
The researchers found that drinking green tea catechins with or without caffeine the HbA1c value non-significant with 0.04% [95% CI = − 0.15% to 0.08%] reduced.
The researchers found that drinking green tea catechins with or without caffeine the HOMA-IR-value (the degree of insulin resistance) non-significantly with 0.05 [95% CI = − 0.37 to 0.26] reduced.
On the basis of the found results the researchers concluded that after 12 weeks drinking green tea with or without caffeine the sober blood sugar reduced.

Diabetics have an increased fasting blood sugar, HbA1c, fasting insulin levels increased high-and HOMA-IR-value. Problems with the eyes, limbs or kidneys with diabetics is the result of a sober for years, increased blood sugar.
