PROBLEM TO BE SOLVED: To provide an estimation method of an intestine age and an evaluation device of the intestine age which can estimate the intestine age.SOLUTION: An estimation method of an intestine age comprises an estimation step for estimating an intestine age of an object person by use of an artificial neural network. The neural network is constructed by using an intestinal bacterial flora database in which following items are associated with each other: an identifier which identifies each of a plurality of subjects having different ages; a value representing respective ratios of all intestinal bacteria extracted from each of the subjects to a plurality of intestinal bacteria in all kinds of bacterium classification levels extracted from the subjects; and a value representing an age of each of the subjects.SELECTED DRAWING: Figure 2 |
