While not necessarily the tastiest variety, Tommy Atkins mangoes became popular among mango growers in Florida in the 1950s. Besides, they are broadly oval shaped with a mildly sweet, juicy flesh. These mangoes are in fact deemed a great source of vitamin C and A, as well as fiber. They also contain folate, vitamin B6 and minerals like potassium, calcium, and iron. Like most mangoes, the Tommy Atkins mangoes contain enzymes that are beneficial for digestion. In addition, they contain lutein, zeaxanthin and vitamin A, which support eye health.
