STUDY TITLE: A genome-wide investigation of food addiction
SUMMARY: Identification of 2 genetic loci correlated with the development of food addiction.
DESCRIPTION: Foods, especially those that are high in sugar, fat, or salt, can trigger the release of the feel-good chemical known as ‘serotonin’ in our brains. Though an ongoing debate within the scientific community, food addiction is believed to share mechanisms with drug addiction. Food addiction can involve binge eating and a lack of control around food, putting those affected at a high risk of developing obesity. To identify genetic variants that are associated with food addiction, this study examined the genomes of 9,314 women of European ancestry. Researchers discovered 2 loci correlated with food addiction. The first locus is in a gene that plays a role in food metabolism, and the other was previously linked to brain development. The study did not uncover direct genetic links between food and drug addiction.
DID YOU KNOW? Overcoming food addiction is very difficult. Avoiding trigger-foods that you binge on and finding healthier options may help mediate food addiction. [SOURCE]
