First things first, unwashed fruits should never be consumed as they might have pesticides and sometimes the soil contains Toxoplasma parasite that is present in animal faeces which is quite dangerous. Expecting mothers who are diabetic should refrain from eating high sugar fruits.
Pregnant women are advised to stay away from this fruit. Pineapples have a high bromelain content which is an enzyme that softens the cervix and can also trigger uterine contractions. It can induce early labour which is not good for both the mother and the baby. Also, consuming pineapples in large quantities can lead to dehydration and diarrhea.
Grapes are categorised as one of the most nutritious fruits but many people have raised the question on their effect on pregnant women. They contain a lot of resveratrol compound that is present in their skin. This compound is poisonous and toxic and can be harmful to expecting mothers. Moreover, the digestive system of pregnant women is quite weak at this time and black grapes are difficult to digest.
Raw papayas are known to lead to miscarriages if consumed by pregnant women. Papaya contains latex which triggers uterine contractions that can be dangerous. Also, they are consumed to relieve problems like constipation. But if eaten in large amounts, they can cause surplus bowel movements that put pressure on the uterus.
The water content of the watermelons keeps the body hydrated. It also flushes out the harmful toxins from the body but while doing this the baby gets exposed to these toxins which is not good for the baby. Also, consuming large amounts of this fruit can raise blood sugar levels in women with gestational diabetes.
Another fruit that the expecting mothers should avoid is peach as it is considered a hot fruit. Consuming peaches in large quantities can produce heat in the body that can lead to internal bleeding and even miscarriage. If you want you can have them in moderation but without the peel as the tiny follicles on their skin can cause irritation in the throat.
