| Outline of Final Research Achievements |
Forty-four female students (mean age, 20.2 ± 3.3 years) consumed 30 g pickles for 2 weeks and were divided into 3 groups: viable-cell intake subjects (n = 14), dead-cells intake subjects (n = 15), and placebo subjects (n = 15). Natural killer (NK)-cell activity in serum from dead-cell intake subjects was 37.5 ± 17.0% before the start of the test-food intake and 47.7 ± 20.1% after intake, indicating statistically significant effects (p < 0.01). The number of days with bowel movements significantly increased from 3.8 ± 1.5 to 4.9 ± 1.8 days in the dead-cell intake group., Feeling of incomplete evacuation reduced and refreshed feeling increased among the subjects with constipation. Thus, marked enhancement of NK-cell activity and improved bowel symptoms were observed in subjects consuming pickles containing dead lactobacillus cells. Daily adequate calcium intake is predicted to be crucial to develop optimal peak bone mass and to preserve bone mass throughout life.
