“…Otro estudio transversal realizado en diabéticos tipo 2 japoneses mostró que la ingesta de fibra dietaria se asociaba a una reducción de la HbA1c (32). Finalmente un meta análisis mostró que una ingesta alta en fibra de hasta 42 g/día o suplementos de fibra de hasta 15 g/día reducía los valores absolutos de HbA1c (33). Sin embargo, en nuestro estudio la ingesta de fibra no presentó asociación con los niveles de HbA1c.…”

Introducción: la hiperglicemia es la característica principal de la diabetes (DM). La restricción de CHO en la dieta presenta el mayor efecto en la disminución de los niveles de glucosa en sangre tanto en DM 1 y 2.Objetivo: asociar la ingesta de macro y micronutrientes con el control metabólico de pacientes con diabetes tipo 2.Material y métodos: se entrevistó a 714 pacientes diabéticos tipo 2 de ambos sexos, entre 27 y 90 años, en centros de salud familiar de Santiago de Chile. Se les aplicó una encuesta alimentaria y una evaluación antropométrica. Se realizó prueba de regresión logística, se estimó además el valor del Odds Ratio (OR) y su correspondiente intervalo de confianza (IC).Resultados: el IMC promedio fue de 30,8 ± 5,7 kg/m2, el 29,8% de los sujetos tenía una HbA1c compensada. Se puede observar que solo la ingesta elevada de carbohidratos (percentil 75) se asoció con un incremento en el riesgo de tener HbA1c elevada OR = 2,7 (IC 95% 1,5-4,8; p < 0,001).Conclusiones: la ingesta elevada de carbohidratos de rápida absorción, altos en sacarosa y bajos en fibra se asocia como factor de riesgo en el incremento de HbA1c. La ingesta total de energía y el patrón de alimentación saludable se debe priorizar sobre la distribución de macronutrientes. Es importante la asesoría de un experto en nutrición especializado en diabetes quien, en colaboración con el equipo médico, debe determinar el tratamiento para cumplir con los objetivos individuales del paciente.

“…Fresh pears contain both soluble and insoluble fiber [58]; a recent review has shown that the dietary fiber in pears is ~30% soluble and ~70% insoluble [59]. In general, soluble fibers have positive effects on serum lipid levels [60,61] and glycemic control [62] and insoluble fibers have positive effects on laxation [63]. Our study did not show differences in lipid levels or markers of glycemic control; perhaps the amount of soluble fiber consumed was too low to see a response or the UI of fiber; although mean fiber consumption among consumers in this study nearly met the daily value of 25 g [64], did not reflect long term intake that would have affected lipid or blood glucose levels.…”

It is also possible that fiber intake was not high enough to affect these CVRF [62].…”

No studies have examined the association of consuming fresh pears on nutrient intake or adequacy, diet quality, and cardiovascular risk factors (CVRF). The purpose of this study was to examine these association in adults (N=24,808) participating the NHANES 2001-2010. Covariate adjusted linear regression was used to compare macronutrients, diet quality, and CVRF. Diet quality was determined using the Healthy Eating Index-2010 (HEI-2010). The National Cancer Institute method was used to estimate the usual intake (UI) of nutrients. Appropriate sample weights were used. Percentages of the population below the Estimated Average Requirement (EAR) or above the Adequate Intake (AI) were determined. Consumers had higher mean intakes of total sugars and lower total, mono-, and saturated fatty acids, and added sugars than non-consumers; consumers also had higher UI for vitamin C, copper, magnesium, and potassium (p<0.01). Consumers had a higher percentage population meeting the EAR for vitamins A and C, copper, and magnesium; consumers had a higher percentage above the AI for fiber (p<0.01). HEI-2010 was higher in consumers (52.4 ± 0.4 vs 48.5 ± 0.3) (p<0.01). Compared to non-consumers, consumers were 35% less likely to be obese (p<0.05). Fresh pears should be encouraged as a component of an overall healthy diet.

Dietary Fibre and Cardiovascular Risk in Diabetes Mellitus

Patients with type 1 and 2 diabetes have a higher risk of cardiovascular disease compared to non-diabetic populations. Improved dietary quality is essential to control risk factors and can prevent or delay cardiovascular disease in diabetic patients. Higher dietary fibre intake was inversely associated with cardiovascular disease in several general population studies. However, in diabetes mellitus, and especially type 1 diabetes, little information is available. A literature study was performed to summarize the available evidence for a possible relationship between fibre consumption from natural foods and the risk of developing cardiovascular disease in people with type 2 and type 1 diabetes. In November and December 2014, PubMed was searched for relevant articles. The full texts of 15 articles were reviewed. Prospective cohort studies reported an inverse association between dietary fibre intake and all-cause and cardiovascular disease mortality risk in both diabetes types. Randomized controlled trials were inconsistent. For type 2 diabetes, dietary fibre intake was related to lower plasma glucose and plasma lipid levels. In terms of foods, mainly legume and cereal fibre, vegetables and fruits were found to beneficially influence cardiovascular risk in patients with type 2 diabetes. For type 1 diabetes, no foods were investigated, but dietary fibre had some beneficial effects on cardiovascular risk factors from limited trials. To lower CVD risk in people with type 1 diabetes in the future, the potential of raising fibre in the diet should be further explored.
