The challenge of provision of a much wider range of foods of relatively low glycemic response than is currently available, especially in terms of cereal products, has been highlighted in recent years and this has particular relevance to bread consumption. Although there has been some transition to brown bread consumption, white bread remains a firm feature in the typical average western diet. This review first outlines the relationship between the glycemic impact of foods and health. What is important is that relatively small differences in glycemic potency of regularly consumed starch foods have been shown to have beneficial effects on health outcomes. Second, factors affecting glycemic response with particular application to white bread formulations are discussed. Novel ways of reformulating this highly favored carbohydrate staple, by using composite flours, with the aim of developing products of reduced glycemic response are highlighted in this review. Importantly, a new and significant focus on the role of unavailable carbohydrate in glycemic improvement is emerging. This has important application in increasing accessibility to health benefits by contributing to the prevention of and management of glucose intolerance, insulin resistance, and associated chronic disease to a wider range of consumers.
Todo proceso de identificación biométrica debe establecerse sobre unos parámetros de estudio convenientemente jerarquizados. Sin embargo, hasta el momento actual, la literatura científica del ámbito I.F.L. no aporta referencias de categorización suficientemente significativas. Tal circunstancia, podría asociarse a diferentes causas: breve trayectoria histórica de las técnicas, carácter multidisciplinar de las aproximaciones de estudio relacionadas, etc. Transcurridos veinte años desde su creación, el laboratorio de Acústica Forense de la Policía Científica española, considera llegado el momento de materializar su propia experiencia en unas referencias concretas de investigación científica. En este sentido, la determinación del valor identificativo de diversos parámetros puede considerarse ya un objetivo alcanzado. En el presente trabajo, se expone un rango de clasificación de los principales parámetros fono- articulatorios y acústicos del español hablado, dentro del marco metodológico desarrollado por el laboratorio de la Policía Científica de España. Para ello, se ha realizado una evaluación parcial de la casuística real analizada por sus científicos durante un período de 5 años, incluyendo un total de 119 locutores y 2.329 parámetros.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
