LCT and colorectal cancer: Moreover, in MR analyses utilising the lactase persistence gene as a proxy for milk intake, which has been shown in a European population to predict a 17.1 g/day per allele difference in milk intake [40], a lower risk of colorectal cancer was observed among those who had the lactase persistence genotype and thus were assumed to consume more milk (odds ratio per allele: 0.95, 95% CI: 0.91–0.99) [41].
