There is no specific fruit than can be deemed as the healthiest due to the fact that all fruits have nutritious value.

A wide variety of fruits should be consumed regularly to improve health and strengthen the immune system, as different fruits contain different types and concentrations of nutrients. The American Cancer Society recommends consuming at least nine servings of fruits and vegetables a day to reduce the risk of cancer by 50 percent.
