In many countries, excessive consumption of sodium chloride (salt) has become a serious social problem and reducing salt has been required. Herbs have been reported to enhance the saltiness of food; however, few studies have focused on the numerical evaluation of the degree of saltiness enhancement by herbs. The purpose of this study was to quantify the degree of saltiness enhancement by herbs via human sensory evaluation using a visual analog scale (VAS). The sensory evaluation was conducted on 69 students who were able to arrange the five different saline concentrations in order. The sensory salt concentration of herb-added 0.4 wt% saline solutions were perceived in comparison with the saltiness of 0.2 to 0.6 wt% reference saline solutions. The results were recorded by an arrow on a VAS. Hot-water extracts of the herbs basil, rosemary, parsley, anise, and oregano were used. The sensory salt concentration of a 0.175 wt% herb-added saline was equivalent to the actual salt concentration (0.4 wt%). However, the sensory salt concentrations of salines with 0.35 wt% herb extracts were significantly higher (p,0.001). There were no significant differences in the saltiness-enhancing effects depending on the species of, preference for, and familiarity with a particular herb. It was estimated that the addition of 0.35 wt% herb extracts enhanced the salty taste of the saline by 1.13 to 1.22 times.
The purpose of this study was to clarify the body composition and blood profile in college American football players, and whether the differences can be referred to their playing positions; Lines vs Backs. Body compositions, blood profile and nutrients intake were investigated. The Linemen showed a significant higher %BF than Backs, and most of the Linemen were assessed as obese according to their %BF and BMI. The risk of dyslipidemia in Linemen was higher than that in the Backs. There were no obvious difference between Linemen and Backs in their intake amount of energy and all nutrients per person. However, when compared in per body-weight, the intake amount of energy and 3 major nutrients were significantly low in Linemen than Backs. Furthermore, the data indicate that dietary awareness and diet behavior are relatively poor in the Linemen. Since body weight is the most crucial factor of Linemen for their playing performances, it can be speculated that their necessity to gain body weight may have led them to be obesity. Since weight-gain is not desirable in the aspect of metabolic disorders prevention, our result indicated that Linemen, rather than the Backs, are the potential target who need an appropriate nutritional support by dietician to control their nutritional intake and body weight, not only for achieving sport performance but also for preventing metabolic disorders. Therefore, it was suggested that periodical survey of blood profile and body composition, together with appropriate nutritional support by dieticians, may be helpful for Linemen, in future.Jpn J Phys Fitness Sports Med, 62(5): 413-423 (2013)
A longitudinal study was conducted to assess associations between snack energy intake and either body mass index (BMI) or nutrient intake in Japanese children. A baseline survey was conducted with 243 children aged 6-7 y, and follow-up was performed 4 y later. Finally, 189 subjects were selected for the analysis. Snack intakes were obtained from self-administered records by guardians. The daily habitual whole dietary intake and exercise/sleep hours were obtained by questionnaires during the follow-up. Subjects were grouped into three, as per snack energy intake tertiles at baseline. Differences and linear trends between the three groups were tested for the mean values of snack energy intake, BMI, and nutrient density, 4 y after the baseline survey. In follow-up, the snack energy intake (kcal) in females was significantly higher in the intermediate (335635, p,0.01) and high (318632, p,0.05) groups than in low group (196625). There was no significant difference in follow-up BMI in the three groups. However, after adjustment of the baseline BMI, a significantly positive linear trend (p,0.05) was observed in the follow-up BMI in females. There was no significant difference in total energy intake per day. In contrast, a significantly negative linear trend (p,0.05) was observed among the three groups in dietary nutrient density of calcium and vitamin A in females. These results suggest that, in females, a higher intake of snacks may affect the daily dietary balance, resulting in a higher BMI and lower mineral and vitamin intakes.
