Whole-grain wheat - disproven!

.



The effects of whole-grain compared with refined wheat, rice, and rye on the postprandial blood glucose response: a systematic review and meta-analysis of randomized controlled trials, Kathy Musa-Veloso et al., The American Journal of Clinical Nutrition, Volume 108, Issue 4, 1 October 2018, Pages 759–774,

Quote:

The consumption of ground (wholemeal) wheat, compared with white wheat, was not associated with a significant reduction in blood glucose AUC [Area Under Curve] (−6.7 mmol/L ⋅ min; 95% CI: −25.1, 11.7 mmol/L ⋅ min; P = 0.477). The consumption of wholemeal rye, compared with endosperm rye, was not associated with a significant reduction in blood glucose AUC (−5.5 mmol/L ⋅ min; 95% CI: −24.8, 13.8 mmol/L ⋅ min; P = 0.576). ...

Note: there was some reduction in blood glucose spike (area under curve) following a meal with whole-grain rice versus white rice!

The consumption of intact (whole-grain) rice, compared with white rice, was associated with a significant reduction in blood glucose AUC (−40.5 mmol/L ⋅ min; 95% CI: −59.6, −21.3 mmol/L ⋅ min; P < 0.001).

Could it be that postprandial glucose is not important? The long lived healthy white rice eating Asians do not eat the so called healthier brown rice.And yet their health results are a matter of record.White rice is easy to digest and I have often heard how important the digestive system is to health and longevity.Your thoughts.

Hi JC,
You are probably correct, higher glucose spike by white rice seems to be less harmful than nutrient-blocking (*) effect of whole rice. I am not 100% sure which particular study reported major vitamin deficiency among Asians consuming whole rice versus white rice. I think it was discussed years ago on Weston A Price .org website.

Generally, glucose spikes not always seem harmful if "area under curve" of insulin is maintained normal. Which happens if a patient is NOT insulin resistant. OTOH, if insulin is always high (i.e. insulin resistance/metabolic syndrome) then the risk of almost everything goes up even if glucose is normal and not spiking.There was a study that tested it on diabetics T1.

Stan
