JOURNAL FREE ACCESSThe objective of this cross-sectional study was to evaluate whether nutritional and physiological factors are associated with the skin condition of young women. Data on skin condition, physiological measurements, dietary intake of nutrients (2 days), mental condition, and lifestyle were obtained from 54 female students (aged 20-22 yr) without coexisting skin disease. Skin condition and physiological parameters (body temperature, energy expenditure, and autonomic nervous system [ANS] activity) were measured using noninvasive techniques. Statistically significant associations were found between area of epidermal corneocytes and energy metabolism and between the degree of hydration and dietary intake of vitamins A and B1, and the activity of the sympathetic nervous system. Associations were also observed between barrier function measured as transepidermal water loss and dietary intake of carbohydrate, vitamin B1, and vegetables. Mental condition and the use of air conditioners were also associated with skin condition. Our data suggest that nutritional factors as well as a higher level of metabolism and ANS activity affect skin condition in young women.View full abstractDownload PDF (885K) -

JOURNAL FREE ACCESSWe recently established criteria for discriminating between young women with and without chills. Using these discriminative criteria, we investigated the effect of royal jelly (RJ) on chills in young women. Participants with chills (n=24) were randomly assigned to RJ-low (1.4 g/day), RJ-high (2.8 g/day), and placebo groups. Using a double-blind protocol, young women took RJ tablets once a day for 2 weeks. We measured the severity of complaints related to chills, peripheral circulation, skin surface temperature of the fingers, and the recovery of skin surface temperature after mild cold-water immersion. Statistical analysis revealed that the skin surface temperature was significantly increased after daily intake of a high dose of RJ and that the difference between the underarm and surface temperatures was significantly reduced in the RJ-high group compared with the pre-treatment level. Furthermore, we found that RJ significantly facilitated the recovery of skin surface temperature.View full abstractDownload PDF (1447K)

JOURNAL FREE ACCESSThe purpose of this study was to examine differences in the feeling of relief (comfort induced by food ingestion) after intake of different types of soup, and the effects of psychological and physiological factors on postprandial sense of relief. Before the examination, a sensory test was performed to classify test samples (corn potage [90 kcal], chicken consommé [43 kcal], and iso-caloric but low-flavor corn and chicken placebo soups) using 6 trained panels. For the main test, 11 women (age 22.6±0.3 yr) consumed a soup as breakfast after an overnight fast on four different days in randomized order. Relief and fullness scores, heart rate, sympathetic and parasympathetic nervous system (PNS) activity using heart rate variability analysis, and energy expenditure using gas analysis were measured before feeding and at 1-h intervals after feeding. According to the preference assessment, the most preferred soup was corn potage followed by chicken consommé, and the least preferred were the two placebos. Postprandial relief scores were significantly higher after ingestion of corn potage than after other soups, being positively correlated with preference scores, fullness scores and heart rate. A negative correlation with PNS activity was also observed. Our data suggest that ingestion of corn potage provides a greater feeling of relief, in terms of preference, fullness, and increase in heart rate.View full abstractDownload PDF (695K)
