Starch and fibre intake and glucose postprandial response of dogs

Abstract

Fibre has been studied to reduce the postprandial glucose response of dogs, but the results are inconsistent. Starch intake, however, was not properly considered in the published RESUMO Fibras têm sido estudadas como opção para reduzir a resposta glicêmica pós-prandial de cães, mas os resultados obtidos têm sido inconsistentes. A ingestão de amido, no entanto, não tem sido adequadamente considerada na interpretação dos resultados de algumas dessas pesquisas. O presente estudo investigou, em cães adultos não obesos, os efeitos da ingestão de amido e fibra sobre a resposta pós-prandial. Celulose (CEL), carboximetilcelulose (CMC), fibra de ervilha (PE) e fibra de cana-de-açúcar (SCF) foram combinadas, gerando seis dietas com 33% a 42% de amido: dietas SCF+CEL e PE+CEL com alta fibra insolúvel (IF=22%) e baixa fibra solúvel (SF=2,5%); dietas SCF+CMC e PE+CMC com alta fibra solúvel (SF=4,5%; IF=19%); dietas CMC e CEL como controles baixa fibra (14%). As dietas foram fornecidas aos cães

Nutritional factors related to glucose and lipid modulation in diabetic dogs: literature review

“…The conclusion was that higher-fiber diets do not lead to better glucose profiles; however, different carbohydrate content of commercial versus high-fiber diets may have been a confounding factor in the interpretation of glucose control: the effects of low starch versus the effects of high fiber. Monti et al (2016) observed in healthy dogs that diets with the same amount of starch did not lead to different glucose responses when compared to diets with fiber levels ranging from 14% to 24% of the dry matter. Diez et al (1998) reached the same conclusion; no changes in glucose levels were observed when they supplemented diets with 7% of dry matter as guar gum, inulin, or beet fiber.…”

“…The authors attributed these effects to the lower starch content, and suggested they would be even more significant in dogs with DM due to the changes in endocrine control. Monti et al (2016) and Murray et al (1999) also found decreased postprandial glucose levels in healthy dogs, which they attributed to the lower starch intake.…”

Effects of pea with barley and less-processed maize on glycaemic control in diabetic dogs

“…As starch appears to be the main nutrient influencing changes in postprandial glucose concentration, it is essential to discuss its role in the results obtained in this study. It is known that the influence of starch on control of glycaemia is owing to both the amount and type of starch consumed (23,24,(27)(28)(29)31,47,48) . In this study, there was a difference between the treatments regarding the main starch source included in the diet: peas and barley v. maize.…”

“…It has been shown that starch digestibility is highly variable and is affected by several factors, such as sources, particle size, amylose:amylopectin ratio (25) and gelatinisation process that may interfere with the postprandial glycaemic curves in healthy dogs (23)(24)(25)(26)(27)(28) . Nevertheless, studies on this same factor in diabetic dogs were not found.…”

<b>Efeitos do emprego de amido resistente decorrente do processo de extrusão no controle glicêmico de cães diabéticos</b>

“…Estudos demonstraram que o tipo, a quantidade e o processamento do amido podem interferir na curva glicêmica pós-prandial de cães saudáveis (NGUYEN et al, 1998;BOUCHARD, 1999;CARCIOFI et al, 2008;ROBERTI-FILHO, 2013;MONTI et al, 2016). Porém, pesquisas com esta temática em cães diabéticos são escassas.…”
