Abstract
The invention relates to a method of determining the effect of betanins on tumor formation in epidermal tissue in mammals which have been exposed to a substance which initiates or promotes tumor formation by sequentially exposing a first group of mammals to a topically applied chemical substance selected from the group consisting of tumor promoters and tumor initiators; providing the first group of mammals with drinking water containing betanins, said betanin having been extracted from beetroot; measuring a percentage of mammals in the first group which exhibit epidermal tumors; and comparing the percentage of mammals in the first group which exhibit epidermal tumors to a percentage of mammals in a second group which exhibit epidermal tumors, said mammals in the second group having been (a) exposed to a chemical substance selected from the group consisting of tumor promoters and tumor initiators and (b) providing with drinking water containing no betanins.
