benefit for steadily the improvement of HbA1c in SYBR group while almost subjects in WR group
consumed Hommali105 contained 1.5 g/100g of dietary fiber. This fact could be explained why after
intervention, SYBR group had gradually and significantly reductions of HbA1c while WR group had
HbA1c lower than wk0 but after wk8 were not further decreased (higher intake of 3.8 g dietary fiber/d).
Our results was conformable with a systematic review (45 prospective cohort studies and 21
randomized-controlled trials) found that intake 370 g/d of whole grain had an approximately 26%
lower risk in diabetes mellitus [11], and who ate 59.1 g/d would lower risk of deterioration in glucose
tolerance than who ate less than 30.6 g/d [12].
The UK Prospective Diabetes Study (UKPDS) [13] and the Diabetes Control and Complications
Trial (DCCT) also demonstrated that the improving HbA1c by 1% for people with diabetes reduce the
risk of micro-vascular complications (retinopathy, nephropathy and neuropathy) by 25% [14]. Similar
with the American diabetes association (ADA) guidelines that patients with diabetes should be control
the HbA1c less than 7% for reduce risk of complications [15]. Nonetheless, the benefits of SYBR
consumption may be clear detected for a longer period study.
Conclusion
In conclusion, the results from this study suggested that substituting Sangyod Phattalong
brown rice for white rice at least two meals/day may have more benefits to type 2 diabetic patients
than who follow nutritional guidelines but still eat white rice.
