We've known for years that sugar isn't good for us. It promotes tooth decay, provides quick highs and lows and offers nothing but empty, nutritionless calories that pack on the pounds. However, it appears that it is even worse than we previously thought. Researchers recently determined that refined sugar is actually more addictive than cocaine. In a recent study rats were given a choice between sugar water and cocaine, and 94% them chose sugar. Even the rats that had previously been addicted to cocaine switched to the sugar once it was a choice. No wonder it's so hard to give up that 3 pm pack of M&M's, it's more addictive than illegal drugs.
