The glycemic response to Naturo fruit bar that is commercially available in India was determined against a glucose sta dard in a non-blind, repeated measure, crossover design trial.
Eleven healthy subjects (mean age 37.3 (SD 5.5) years and mean BMI 213 (SD 36) kg/m2) were recruited to the study. Subjects were given Naturo fruit bar and a standard food (glucose), on separate occasions, each containing 50 grams carbohydrate. Blood glucose was determined after overnight fasting (0 hours) and at 30, 60, 90 and 120 min after the consumption of each test food. For Naturo fruit bar, the glycemic index (GI) value was calculated geometrically by expressing the incremental area under the blood glucose curve (iAUC) as a percentage of each subject's average iAUC for the standard food.
The GI value of Naturo fruit bar was found to be 38.50. As per the Food and Agriculture Organization, GI cut-off values are as follows: low <55; medium 56-69 inclusive, high >70. Therefore Naturo fruit bar could be classified under low glycemic food/nutrient.
Considering the widespread consumption of fruits/bars in India, this information is valuable for people who prefer to use low glycemic food which offer many beneficial effects because their consumption significantly reduces the GI of the diets of the Indian population.
在一项非盲法、重复测量、交叉设计试验中，以葡萄糖标准品为对照，测定印度市售的纳图罗水果棒的血糖反应。
招募了11名健康受试者（平均年龄37.3（标准差5.5）岁，平均体重指数213（标准差36）kg/m²）参与该研究。在不同时间分别给受试者提供纳图罗水果棒和一种标准食物（葡萄糖），每种食物含50克碳水化合物。在过夜禁食后（0小时）以及食用每种测试食物后30、60、90和120分钟测定血糖。对于纳图罗水果棒，血糖生成指数（GI）值通过将血糖曲线下增量面积（iAUC）表示为每个受试者标准食物平均iAUC的百分比进行几何计算。
发现纳图罗水果棒的GI值为38.50。根据联合国粮食及农业组织的标准，GI临界值如下：低＜55；中56 - 69（含），高＞70。因此，纳图罗水果棒可归类为低血糖生成食物/营养素。
鉴于印度水果棒的广泛消费，这一信息对于那些倾向于食用低血糖生成食物的人很有价值，因为这类食物具有诸多有益效果，其消费能显著降低印度人群饮食的血糖生成指数。
