Abstract
Previous studies have shown the benefits of native banana starch (NBS) supplementation in improving glucose metabolism and reducing body weight (BW) in humans. However, the effect of this starch on appetite regulation is unknown. The aim of this study was to examine the effects of NBS rich resistant starch on subjective measurements of appetite, energy intake, and appetite hormones in healthy subjects. Postprandial glucose and insulin responses were also assessed. In a randomized, single-blind, crossover study, 28 healthy young subjects consumed a beverage containing either 40 g of NBS or 40 g of digestible corn starch (DCS) on two separate occasions. Effects on appetite were estimated using visual analogue scales (VAS) and satiety hormone responses. At the end of the intervention, participants were provided with a pre-weighed ad libitum homogeneous test meal. After a washout period of 1 week, subjects received the alternative treatment. NBS supplementation induced a reduction in food intake, glucose area under the curve (AUC)-180 min, and insulin AUC-180 min. However, there was no associated effect on the subjective appetite ratings or gut hormones. NBS supplementation may help to reduce meal size and control BW.
Highlights
IntroductionThe combined prevalence of overweight and obesity rose by 27.5% for adults and by 47.1% for children between 1980 and 2013
Waist circumference (WC) and waist-hip ratio (WHR) values corresponded to the normal range in both genders according to standards for Mexican population
All of the participants exhibited fasting normoglycemia according to the American Diabetes Association (ADA), with glycemia values
Summary
The combined prevalence of overweight and obesity rose by 27.5% for adults and by 47.1% for children between 1980 and 2013. Mexico is among the countries with the highest prevalence of obesity in both adulthood and childhood [1]. The ongoing epidemic has led researchers to focus on finding novel ways to prevent weight gain or to reduce body weight (BW). This goal is especially important considering that obesity is one of the major risk factors for type 2 diabetes (T2D) and cardiovascular disease (CVD).
