In many countries, pomegranate is the number one recommended fruit for all blood related illnesses, including iron deficiency, or anemia. One of the oldest foods known to man, pomegranates are also known to boost fertility and rev up stale libidos. Newly discovered compounds in pomegranates called punicalagins have been shown to be immensely beneficial to the heart and blood vessels, too. Pomegranates also help fight depression and are a great food to add to your daily diet, regardless of whether you are iron deficient or not.
