Despite the lack of international agreement regarding the definition and classification of fiber, there is established evidence on the role of dietary fibers in obesity and metabolic syndrome. Beta glucan (β-glucan) is a soluble fiber readily available from oat and barley grains that has been gaining interest due to its multiple functional and bioactive properties. Its beneficial role in insulin resistance, dyslipidemia, hypertension, and obesity is being continuously documented. The fermentability of β-glucans and their ability to form highly viscous solutions in the human gut may constitute the basis of their health benefits. Consequently, the applicability of β-glucan as a food ingredient is being widely considered with the dual purposes of increasing the fiber content of food products and enhancing their health properties. Therefore, this paper explores the role of β-glucans in the prevention and treatment of characteristics of the metabolic syndrome, their underlying mechanisms of action, and their potential in food applications.
尽管在纤维的定义和分类方面缺乏国际共识，但关于膳食纤维在肥胖和代谢综合征中的作用已有确凿证据。β-葡聚糖是一种可从燕麦和大麦籽粒中轻易获取的可溶性纤维，因其多种功能和生物活性特性而备受关注。其在胰岛素抵抗、血脂异常、高血压和肥胖方面的有益作用不断得到记载。β-葡聚糖的可发酵性及其在人体肠道中形成高粘性溶液的能力可能构成其健康益处的基础。因此，β-葡聚糖作为食品成分的适用性正被广泛考虑，目的是双重的，既增加食品的纤维含量，又增强其健康特性。因此，本文探讨了β-葡聚糖在代谢综合征特征的预防和治疗中的作用、其潜在作用机制以及在食品应用中的潜力。
