Beta, you can eat mangoes but soak them in water for a few hours first to reduce the 'garmi' (heat). Also, eat only half a mango a day during the first trimester.
Yes, you can eat mangoes. My doctor told me they are rich in vitamin A and C, but warned me to eat only one small mango a day because of the high natural sugars.
Yes, but be very careful with the portion size because mangoes can spike your blood sugar quickly. I had gestational diabetes, so I had to strictly limit it to a few slices.
