You can't eat more dried mangoes. Not just dried mangoes, but everything is enough. Eating too much is easy to be counterproductive.
Dried mango is processed from mango, and its heat is much higher than mango itself. Eating too much can easily lead to excessive calorie intake and indigestion, which is one of them.
Secondly, mangoes are prone to damp heat when eaten too much, and dried mangoes made from them are no exception, so people in damp heat constitution need to pay special attention.
