In diabetes their are several myths and one most common is diabetic people should not eat sweet fruits, Mango is a sweet fruit so it can not be consumed by diabetic people. But truth is different. If you ask to your doctor then he will tell what fruits you can eat but in limited quantity.
Fact is that total amount of carbohydrate in a food affect blood sugar is more than other sources of carbohydrate like sugar. For diabetic people one serving of fruit should contain 15 gm carbohydrate. The size of the serving depends on the carbohydrate content of the fruit. If some fruit contains less carbohydrate then that can be eaten in more quantity.
Mangos are great source of nutrition and carbohydrate also. You can get 15 gm carbohydrate from 85 gm Mango pulp. So it’s good new for people suffering from type 2 diabetes. At least then can eat 1/2 cup mango. There are other benefits of mangos specially for diabetic people as it improves digestion and reduces cholesterol.
If you are diabetic still you can eat 1/2 cup mango but you have to cut other carbohydrate intake to balance your diet.
Above is the reason why diabetic are not advised to eat mangos because eating only 85 gm Mango is very painful for Indians and you have to cut other calorie intake.
