The use of agroindustry by-products (BP) for fortification of wheat bread can be an alternative to waste disposal because BP are appealing sources of dietary fiber. Moreover, it may also contribute to indirect income generation. In this study, sensory, color, and crumb structure properties of breads fortified with fiber rich fraction recovered from four types of agroindustry BP were tested, namely orange (OE), pomegranate (PE), elderberry (EE), and spent yeast (YE). Statistical models for sensory preference evaluation and correlation with color and crumb structure were developed...

In 2011-2012 approximately 26% of Australian children aged between 5-17 years were reported to be overweight or obese. Furthermore, the increase in prevalence of overweight and obesity among US children parallels reported increases in energy intake and portion sizes of common foods, leading to the recognition that availability of larger portion sizes contributes to the rise in overweight and obesity prevalence. Thus, the aim of this time-series analysis was to investigate whether selected food portion sizes in Australian children aged 2-16 years changed between 2007 and 2011-2012...

Dysregulated iron metabolism is associated with altered body composition and nonalcoholic fatty liver disease (NAFLD); however, mechanisms underlying this association remain undefined. We investigated this association in 117 women. Middle-aged women (≥45 years old (y)) were heavier and had lower serum iron, higher serum hepcidin, ferritin, and severe NAFLD incidence than young adult women (<45 y). Age-adjusted linear regression analysis revealed that young adult women with the highest serum iron:ferritin ratio (Tertile 3) had a 5...
