This study examined how slow-soluble innovative candy, named low-solubility amorphous material, affects oral indices such as saliva secretion and halitosis in a randomized, double-blind, placebo-controlled, crossover comparative study. Twenty-four healthy individuals with low saliva production were given one piece of low-solubility amorphous material or placebo candy and their saliva secretion was measured over 20 min. Before and after participants used the test food, we measured the concentrations of three volatile sulfur compounds involved in halitosis and the secretion rate of secretory immunoglobulin A, and participants completed the Profile of Mood States Second Edition (POMS2) and a visual analog scale (VAS). As a result, saliva secretion increased significantly in low-solubility amorphous material candy condition, compared to placebo candy. Furthermore, changes in the hydrogen sulfide concentration, POMS2 Total Mood Disturbance and Vigor-Activity scores, and oral \"moisture\" and \"refreshed feeling\" scores on the VAS were improved more by low-solubility amorphous material candy use than by placebo.

In this study, we investigated underlining mechanisms of the high antitumor effect of aHP using cell experiments.

The study included 786 participants aged ≥65 years from the Kyotango Multipurpose Cohort Study who had available data on their gut microbiota. Frailty was quantitatively assessed by selecting 32 items from the previously reported frailty index, with those scoring ≥0.21 classified as frailty (<i>n</i> = 119) and those with scores <0.21 as non-frailty (<i>n</i> = 667), followed by group comparisons. The frailty group had significantly higher values and rates than the non-frailty group for the following items: age, obesity (in females only), diabetes, hypertension, history of cancer treatment, polypharmacy, disturbed sleep quality, low physical activity, serum insulin levels, and high-sensitivity C-reactive protein. The frailty group had significantly lower levels of nutrients, including plant proteins, potassium (K), magnesium (Mg), iron (Fe), copper (Cu), vitamins B and C, folic acid, and total, soluble, and insoluble dietary fiber.
