In recognition of American Diabetes Alert Day, today’s posts will be covering diabetes, and in particular focusing on prevention strategies. Diabetes mellitus Type II (DM2) is increasing not only in the U.S., but worldwide as well. It is estimated that in 2012, 29 million Americans had DM2, and as many of 8 million of these were undiagnosed.
Pre-diabetes is defined as a fasting plasma glucose of 100-125 mg/dl, or a two-hour oral glucose tolerance test with a reading of 140-199 mg/dl. It was estimated in 2012 that as many as 86 million Americans fell into the pre-diabetes category.
There is much research activity focusing on identifying those at risk for developing DM2 (such as those with pre-diabetes) and for ways to help prevent or forestall it’s progression. A recent study examined the use of curcumin extracted from turmeric as a way to prevent development of DM2 in those already diagnosed with pre-diabetes.
Curcumin is an active ingredient of the Asian spice turmeric, which is a member of the ginger family. Turmeric is a widely used spice in South Asian and Middle Eastern cooking and is grown in India, Nepal, Indonesia, Thailand, Vietnam and elsewhere. Turmeric is also used in Ayurvedic Medicine, and is currently being studied in Western Medicine for possible uses. Curcumin has been shown to have antioxidant and anti-inflammatory properties.
In this study conducted in Thailand. 240 individuals who were diagnosed with pre-diabetes were enrolled. These included both men and women, with an average age of 57. Enrollees were randomly assigned to either the placebo group, or the curcumin treated group. Those in the curcumin group took capsules containing curcumin powder twice a day.
Data was collected for both groups at baseline (prior to initiation of treatment), and at 3, 6, and 9 months. The primary outcome measure was development of DM2. Other measures included changes in beta-cell function, c-peptide (an inflammatory marker), insulin resistance, adiponectin (an anti-inflammatory cytokine), and obesity.
At nine months, 0% of the curcumin group developed DM2, whereas 16.4% in the placebo group developed DM2. This was statistically significant.
In addition, in the curcumin group beta-cell function improved, c-peptide dropped, insulin resistance decreased, and adiponectin increased, all of which represent potential beneficial improvement. Also important, no significant adverse effects of curcumin treatment were noted.
Given the results of this study, curcumin would seem to be a possible way to help prevent diabetes in those at risk.
