[Analysis of the nutrients contents and the blood glucose response of the mixed grains in Chinese people].

OBJECTIVE

To evaluate the nutrients contents and the glycemic index (GI) of the mixed grains and analyze the relationship between the nutrients contents and biological effect.

METHODS

The nutrients contents of mixed grains and control food were determined according to the methods of Chinese national standards. Choose 10 volunteers to ingest 50 g glucose and ingest the steamed bread of mixed grains which imply 50 g carbohydrate the second day. Limosis blood glucose and blood glucose levels during the subsequent 3 hours were determined. Calculating the GI according to the Wolver's method.

RESULTS

The results showed that 100 g of the mixed grains contained dietary fiber (crude fiber) 13.7 g, vitamin B1 0.40 mg, protein 13.5g, ash2.0g, vitamin B2 0.16 mg, calcium 54 mg, iron 7.1 mg and zinc3.00 mg respectively. The absolute increase of blood glucose and the areas increased under the glycemic curves of mixed grains were less than which of glucose (P < 0.05). The GI of the mixed grains bread was 52.6.

CONCLUSION

It was concluded that the high contents of protein, minerals, dietary fiber, VB1, VB2 and the low GI of mixed grains might play an important role in nutritional intervention
