One of the best nutrigenomic research groups from TUFTS University in Boston recently published a paper in the Obesity journal. They looked at the −13910C>T polymorphism on the lactase (LCT) gene. This gene is strongly associated with lactose intolerance.
They found that individuals who had the CC genotype had a significantly lower BMI, lesser waist circumference and lower risk of obesity than T-allele carriers. They also found that when dairy lactose intake was very low, they did not find significant differences in waist circumference or obesity risk between CC and T-allele carriers. However, significant differences were found with higher lactose intake. There have been many controversial results in previous studies investigating the association between dairy products and obesity, these may be explained by the potential heterogeneous (dissimilar, or different) effects of dairy product on lactose tolerant and lactose intolerant individuals, governed by gene variations.
