After chemical induction of mammary tumours, rats were randomly assigned to 4 nutritional groups (15 rats/group). Rats were fed either the EFA 5 diet (with an essential fatty acid (EFA) ratio LA to ALA = 5) or the EFA 1 diet (with an EFA ratio of 1), supplemented with βC (10 mg/kg diet/day, +) or not (w/o).
*: In rats fed the EFA 5 diet, tumour growths (means ± SEM) are significantly different between animals with βC and those w/o βC (p = 0.09, repeated measures ANOVA with time as grouping factor)
Tumor growths are not significantly different between rats fed the EFA 5 and EFA 1 diets w/o βC or between rats fed the EFA 1 diet with βC and w/o βC (p = 0.99, repeated measures ANOVA with time as grouping factor)
