用食纤维,多和缓慢消化粉 (SDS) 丰富的配方谷物产品在健康人群中显著降低了血糖指数 (GI) 和胰岛素指数 (II).
科学领域:
- 营养科学 营养科学
- 食品科学 食品科学 食品科学
- 代谢健康 代谢健康
背景情况:
- 高血糖反应 (GR) 与心脏代谢风险因素有关.
- 饮食成分如多,纤维和粉可以影响GR的消化能力.
- 开发调节GR的食物对公共健康至关重要.
研究的目的:
- 评估配方谷物产品对葡萄糖指数 (GI) 和胰岛素指数 (II) 的影响.
- 调查食纤维,多和缓慢消化粉 (SDS) 在调节血糖反应中的作用.
- 提出新型食品配方,以获得有益的健康效应.
主要方法:
- 一项随机交叉对照研究,涉及12名健康受试者.
- 根据ISO-26642 (2010) 标准测量四种类型的饼干的GI和II.
- 两种丰富饼干 (高纤维,多,SDS) 与两种对照饼干 (这些化合物含量低) 的比较.
主要成果:
- 与对照组相比,富制饼干的GI (46 ± 5,43 ± 4) 和II (54 ± 5,45 ± 3) 显著较低 (GI: 57 ± 5,58 ± 5;II: 61 ± 4,61 ± 4).
- 在缩产品和对照产品之间观察到11-15个GI单位的显著差异.
- 这些有益影响归因于富含配方中的高SDS,多和食纤维含量.
结论:
- 用高食纤维,多和SDS配制的谷物产品有效地降低GI和II.
- 这些发现表明有希望的基于食物的策略来管理心脏代谢风险.
- 建议在SINFONI联盟内进行进一步的长期研究,以确认这些健康益处.
