Effect of oat β-glucan on glycemic index and glycemic load of a nutritional supplement sweetened with sucralose in healthy adults: A randomized clinical trial
Indexación: Scopus; RedalycLas propiedades hipoglicemiantes del β-glucano de avena
son de interés para la industria alimentaria y el área clínica,
por sus potenciales beneficios sobre la salud al disminuir la
respuesta glicémica, el nivel sérico de lipoproteínas de baja
densidad y el índice glicémico de los alimentos. Existen suplementos
nutricionales específicos para diabéticos edulcorados
con sucralosa cuyo índice glicémico y carga glicémica
aún no han sido establecidos. El efecto del β-glucano de
avena sobre el índice glicémico y carga glicémica de un suplemento
nutricional edulcorado con sucralosa, fue determinado
en 13 adultos sanos (6 hombres y 7 mujeres), quienes
consumieron aleatoriamente 4 alimentos en días distintos, de
50 g de carbohidratos cada uno: suplemento nutricional para
diabéticos (FN), suplemento nutricional con β-glucano (FN-
β), y como productos de referencia: solución glucosada (SG)
y pan blanco (PB). Se midió glicemia en ayunas y post- prandial
a los tiempos 15, 30, 45, 60, 90 y 120 min. El área bajo
la curva de glicemia resultó más baja para ambas fórmulas
(FN) 12697±993, (FN-β) 11584 ±1171, que para los productos
de referencia:(SG) 13900±1245, y (PB) 13267 ± 1557.
Los valores de índice glicémico (FN) 67,02 ± 5,69, así como
la carga glicémica resultaron intermedios y más bajos para el
suplemento con β-glucano incorporado (FN –β) 59,8 ± 6,2;
sin diferencias en la concentración de insulina, sugiriendo
que la adición del β-glucano derivado de la avena reduce la
velocidad de absorción intestinal de la glucosa, efecto que
podría estudiarse en diabéticos.The hypoglycemic properties of oat β-glucan is of interest
for the food industry and clinical area, for potencial health
benefits by reducing glycemic response, serum low-density
lipoprotein cholesterol, and glycemic index of meals. There
are specific nutritional supplements for diabetics sweetened
with sucralose whose glycemic index and glycemic load has
not been established. Effect of oat β-glucan on glycemic
index and glycemic load of a nutritional supplement sweetened
with sucralose in healthy adults was determined in 13
healthy subjects (6 men and 7 women) old that consumed
randomly 4 meals of 50 g of carbohydrates each in different
days: a nutritional supplement for diabetics (FN), the nutritional
supplement with β-glucan incorporated (FN-β) and two
reference food, glucose solution (SG) and white bread (PB).
Fasting and postprandial glycemia was measured at times
15, 30, 45, 60, 90 and 120 min. The area under the glycemia
curve was lower for both formulas (FN) 12697±993, (FN-β)
11584 ±1171 than for reference products (SG) 13900±1245,
y (PB) 13267 ± 1557. The values of glycemic index (GI) (FN)
67, 02 ± 5,69 and glycemic load were intermediate and more
lower for the supplement with β-glucan incorporated (FN –β)
59, 8 ± 6,2, with no difference of insulin concentration . Suggesting
that the addition of oat-derived β-glucan reduces the
rate of intestinal absorption of glucose. This effect should be
studied in diabetic.http://www.redalyc.org/articulo.oa?id=5594990800

Neotropical ornithology: Reckoning with historical assumptions, removing systemic barriers, and reimagining the future
A major barrier to advancing ornithology is the systemic exclusion of professionals from the Global South. A recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed a long-standing pattern of highlighting individuals, knowledge, and views from the Global North, while largely omitting the perspectives of people based within the Neotropics. Here, we review current strengths and opportunities in the practice of Neotropical ornithology. Further, we discuss problems with assessing the state of Neotropical ornithology through a northern lens, including discovery narratives, incomplete (and biased) understanding of history and advances, and the promotion of agendas that, while currently popular in the north, may not fit the needs and realities of Neotropical research. We argue that future advances in Neotropical ornithology will critically depend on identifying and addressing the systemic barriers that hold back ornithologists who live and work in the Neotropics: unreliable and limited funding, exclusion from international research leadership, restricted dissemination of knowledge (e.g., through language hegemony and citation bias), and logistical barriers. Moving forward, we must examine and acknowledge the colonial roots of our discipline, and explicitly promote anti-colonial agendas for research, training, and conservation. We invite our colleagues within and beyond the Neotropics to join us in creating new models of governance that establish research priorities with vigorous participation of ornithologists and communities within the Neotropical region. To include a diversity of perspectives, we must systemically address discrimination and bias rooted in the socioeconomic class system, anti-Blackness, anti-Brownness, anti-Indigeneity, misogyny, homophobia, tokenism, and ableism. Instead of seeking individual excellence and rewarding top-down leadership, institutions in the North and South can promote collective leadership. In adopting these approaches, we, ornithologists, will join a community of researchers across academia building new paradigms that can reconcile our relationships and transform science. Spanish and Portuguese translations are available in the Supplementary Material.• Research conducted by ornithologists living and working in Latin America and the Caribbean has been historically and systemically excluded from global scientific paradigms, ultimately holding back ornithology as a discipline.• To avoid replicating systems of exclusion in ornithology, authors, editors, reviewers, journals, scientific societies, and research institutions need to interrupt long-held assumptions, improve research practices, and change policies around funding and publication.• To advance Neotropical ornithology and conserve birds across the Americas, institutions should invest directly in basic field biology research, reward collective leadership, and strengthen funding and professional development opportunities for people affected by current research policies.Peer reviewe
