| Outline of Final Research Achievements |
Our goal is to establish a recommended practical intake level of cancer preventive isothiocyanate (4-methylthio-3-butenyl isothiocyanate) in daikon with reflecting the bioavailability in human body. The MTBITC bioavailability varied among human volunteers, and therefore the MTBITC cancer preventive effect depends on the individual even in the same MTBITC administration level. The difference does not depend on gender, age, height, and weight in individual. The bioavailability was observed upper limit, and the cancer preventive effect might be expected under the limit of bioavailability accordingly. Since variation factor of the MTBITC bioavailability was found in seasons changed over time, it might be useful to estimate the bioavailability in each season, when establish the recommended practical intake level of daikon for cancer preventive effect.
