Reduction in Risk Factors for Type 2 Diabetes Mellitus in Response to a Low-Sugar, High-Fiber Dietary Intervention in Overweight Latino Adolescents

Abstract

Objective: To examine if reductions in added sugar intake or increases in fiber intake in response to a 16week intervention were related to improvements in metabolic outcomes related to type 2 diabetes mellitus risk.Design: Secondary analysis of a randomized control trial.Setting: Intervention classes at a lifestyle laboratory and metabolic measures at the General Clinical Research Center.

Association between Nutrients and Visceral Fat in Healthy Japanese Adults: A 2-Year Longitudinal Study Brief Title: Micronutrients Associated with Visceral Fat Accumulation

“…A study of 85 individuals [23] reported no correlation; however, in a survey of 1114 individuals [21], those individuals who increased their intake of soluble dietary fiber had reduced visceral fat. In addition, an intervention trial reported that dietary fiber [39] and β-glucan [40], which is a type of soluble dietary fiber, are effective for reducing VFA, supporting our results. With regard to folic acid, no significant relationship was identified in an epidemiologic study [41], but an intervention study reported that folic acid intake was effective for reducing visceral fat [42].…”

Vegetable Consumption Is Linked to Decreased Visceral and Liver Fat and Improved Insulin Resistance in Overweight Latino Youth

“…Dietary fiber is a potential mechanism, by limiting insulin response following meals and slowing gastric emptying and thus macronutrient absorption. 34,35 Previous research has shown that increases in dietary fiber in overweight Latino youth contributed to a 4–10% decrease in VAT, 22,36 yet there was no association between fiber and adiposity and metabolic outcomes in this analysis, possibly due to low fiber intake among all participants. Yet, fiber intake was highly correlated with all vegetable serving groups (p<0.0001), and all significant relationships remained when fiber was controlled.…”

Examining the Use of Dietary Fiber in Reducing the Risk of Type 2 Diabetes Mellitus in Latino Youth

“…Chandalia et al (2000) assigned the experimental group to a high fiber diet of 50 g, specifying 25 g soluble and 25 g insoluble fiber, whereas Davis, Ventura, et al (2007) studied the effects of 14 g/1,000 calories increased dietary fiber in Latina adolescents. Similarly, literature by Davis et al (2010) found the fiber equivalent of half a cup of beans per day decreasing visceral adipose tissue and improving insulin secretion, whereas Ventura et al (2009) found the same effects after an increase in the equivalent of one cup of beans per day.…”
