HFCS and table sugar (sucrose) usually contain similar amounts of glucose and fructose. HFCS is obtainable mainly in two forms: HFCS 55 contains 55% fructose and 45% glucose. It is commonly used in soft drinks, and is very similar in sweetness to table sugar.
Bulimia nervosa is an eating disorder and mental health condition. People who have bulimia try to control their weight by severely restricting the amount of food they eat, then binge eating and purging the food from their body by making themselves vomit or using laxatives.
Persons with anorexia nervosa eventually become visibly recognizable because of their severely underweight status. In contrast, those affected by bulimia are typically of normal weight and are not as easily detected. This disorder is characterized by binge eating and purging. Mehler reviews the diagnosis and treatment of bulimia, using a hypothetical case of a 20-year-old woman noted to have severe hypokalemia and metabolic alkalosis. Bulimia is most common in late adolescent females. Comorbidity with other psychiatric disorders is typical, and patients with a concomitant personality disorder (e.g., borderline, narcissistic, and antisocial disorders) have a worse prognosis.
