How healthy are the nutrition habits of today's adolescents? What are eating disorders?
What will be an ideal response?
Many American adolescents do not ingest the appropriate amounts of calcium, iron, and zinc. The primary causes appear to be irregular eating habits and eating disorders. The typical male adolescent needs to consume approximately 3,000 calories per day, while the typical female adolescent needs to consume approximately 2,200 . Given concerns over body image and weight, however, many adolescents will not ingest the number of needed calories. This concern with body image and weight gain can lead to eating disorders such as anorexia and bulimia. Anorexia is characterized by an intense fear of gaining weight. It may prompt the individual to exercise excessively, severely restrict food intake, and to see one's body image as significantly different (heavier) than others view it. Bulimia typically involves a cycle of binge eating followed by purging. Episodes of binge eating typically follow a serious effort to restrict food intake.
