[A]ccording to some new research on how your genes affect the foods you seek out, it’s not your fault [if you have trouble sticking to a healthy eating plan]. You’re not weak-willed, you’re just genetically predisposed to prefer certain foods.

In a presentation at the Experimental Biology Conference in Chicago, Silvia Berciano, a predoctoral researcher in genomics and nutrition at Tufts University, shows how our genes can predispose us to preferring certain types of foods, foods that aren’t always the best for us.

What [Berciano] found were some interesting correlations between eating habits and what are known as single nucleotide polymorphisms — the most common types of genetic variations among people.

Notably, the researchers also found that people whose genes showed a lower number of oxytocin receptors in the brain — oxytocin is the hormone associated with human bondingeat more chocolate and have significantly higher body mass indices, which in turn has its own set of negative health outcomes.
