A food which contains a carbonaceous material capable of adsorbing residual organic contaminants. The carbonaceous material is, for example, either at least one member selected from the group consisting of carbon black, activated carbon, and graphite or nanocarbons. The carbonaceous material preferably is hydrophilic. The carbonaceous material can adsorb residual organic contaminants contained in the food and residual organic contaminants which have accumulated in the body. The carbonaceous material having residual organic contaminants adsorbed thereon is discharged from the body together with excreta. This food can hence inhibit residual organic contaminants from accumulating in the body.
