"In the past decade, studies proved that dark chocolate has many virtues, and, in moderation, can help stave off heart disease and cancer. It can even help you stay slim. There are 300 to 400 compounds in dark chocolate that can help you from head to toe, inside and outside of your body," said Orey, a health journalist who interviewed doctors, dietitians, and chocolatiers while researching her book.

In addition to life-threatening diseases, chocolate can also help with lesser ailments such as anxiety, depression, PMS, and seasonal affective disorder. Because of chocolate's antioxidants, minerals, and vitamins, you can get the same benefits as in red wine and vegetables," she says.

Orey says eating chocolate on a regular basis can add years to your life…possibly by at least five years."
