Two strains of rats, cans of vanilla frosting and a theory have brought science a step closer to finding the genetic causes of binge eating and eventually a treatment. Females are primarily effected by eating disorders with a ratio of only one male for every ten women. These disorders can last for years. During this timeframe, effective treatment is critical since eating disorders have the highest mortality rate of any psychiatric disorder. And if it doesn’t kill, the damage it wreaks can be irreversible. By using different types of female rats, the scientists have effectively reduced the high number of genes that could be implicated in a binge eating disorder, and dramatically narrowed the areas for further research.
