Food Preferences May Be Tied to Our Genes

If you've got an undeniable sweet tooth or just can't seem to stay away from high-fat foods, your genes may be partially to blame. While most of us know the general recommendations for a healthy diet—plenty of fruits, vegetables, and whole grains, and lower amounts of added sugar, sodium, and saturated fat—research shows many of us fail to follow these guidelines. And there's no doubt—eating healthy is easier for some people than for others.

Earlier studies have identified genes associated with a number of behavioral and psychological traits, including stress, impulsivity, addiction, depression, and others. Now, according to researchers, a recent study discovered several gene variants that influences food choices.

For the study, researchers analyzed data from the Genetics and Lipid Lowering Drugs and Diet Network study and identified several genetic variants associated with certain food preferences. For example, variants in the hormone oxytocin led to a higher intake of chocolate, variants in CREB1 and GABRA2 genes were linked to a higher sodium intake, and variants of the SLC6A2 gene were linked to a higher fat intake.
