Ginger may lower fasting blood sugar.
Because ginger has anti-inflammatory properties, Iranian researchers are looking for a positive link between ginger and type 2 diabetes management. Diabetes is, after all, a disease that is often characterized by inflammation.
In an eight-week study published in Complementary Therapies in Medicine, the researchers assigned 88 diabetics to daily ginger capsules or placebo. At the end of the study, ginger users saw an average 10.5% reduction in fasting blood sugar, whereas placebo users saw a 21% increase. HbA1c scores-which reflect blood sugar profiles over an extended period of time-also favored ginger. And ginger improved insulin sensitivity too, as evidenced by improved scores on the QUICKI (quantitative insulin sensitivity check index) test.
The ginger dosage used was 1 g, three times daily.
