Gymnasts' bone mineral characteristics are generally not known before starting their sport. Prepubertal females who enrolled in beginning artistic gymnastics (n = 65) had lower bone mineral than controls (n = 78). However, 2 years of gymnastics participation versus no participation led to a significantly greater accrual of forearm bone area and lumbar spine areal BMD.

Unlike prior reports of adults and adolescents living in the southeastern United States, vitamin D status was adequate in the children of the present study. 25(OH)D concentrations were not positively associated with higher bone mineral.

Background: The principal polyphenols from coffee berry (chlorogenic acids) and apple (flavanols) have recently been shown to improve mood and increase cerebral blood flow in healthy humans. These effects may underpin the cognitive effects of polyphenols seen previously. Objective: The aim of the present paper was to extend previous research by investigating the effects of coffee berry at high and low doses when combined with apple extract on cognitive performance and mood. Design: This randomised, double-blind, placebo controlled, crossover trial included 46 healthy males and females between 18-49 years of age (mean age 23 years) to consume: 1100 mg coffee berry extract, 1100 mg coffee berry extract plus 275 mg apple extract, 100 mg coffee berry extract plus 275 mg apple extract or placebo on 4 separate occasions, completing cognitive and mood assessments pre-dose and then again at 1-, 3-and 6 hrs post-dose. Results: Analysis revealed a consistent pattern of alerting effects following 1100 mg coffee berry extract, with participants reporting increased alertness and vigour and decreased fatigue following this treatment. Limited effects on cognitive function were observed. Specifically, faster peg and ball performance (executive function) was observed following 1100 mg coffee berry plus apple extract and accuracy on the Rapid Visual Information Processing (RVIP) task increased on the third of four repetitions following 1100 mg coffee berry alone. Interestingly, more false alarms on RVIP were

The topic of sweet taste and the relationship to health is one that has been of interest to researchers for many years. Recently, reduced consumption of sweet-tasting foods and beverages, regardless of how they are sweetened (ie, caloric or low/no-calorie sweeteners), has been recommended by some health authorities to encourage reduced sugar consumption. The hypothesized rationale is that human attraction to sweetness could increase the risk of developing less healthy eating patterns. This article summarizes the work presented by Professors Appleton and de Graaf on the topics of sweet taste perceptions and preferences, food intakes and obesity, during an American Society for Nutrition webinar on July 28, 2020, and finds little evidence to support this hypothesis.
