Hi, Pineapple is a nutritious fruit as it contains a great number of Vitamins and Minerals supplemented by a high amount of dietary fibre. It contains Vitamin B1, B6, C, Iron, Copper, Magnese etc, which are immensely required for healthy growth and development of an unborn baby.
However, apart from its high nutritive value, it also contains a compound called 'Bromelain', which can cause contractions due to softening of cervix leading to early labour. Therefore, it should be avoided in the first trimester, can be taken in a small amount in the second trimester when the fetus is stable and can be moderately consumed in the third trimester. It is better to discuss with your gynaecologist before taking any food or medicine in order to ensure the complete safety of you and the baby. Have a healthy, delightful and safe pregnancy.
