Answer: You can eat grapes in moderation as they provide vital nutrients such as vitamins, antioxidants (1), organic acids, fiber, folic acids, pectin and more, which support the biological changes happening during and post pregnancy. However, you should avoid eating grapes in the last trimester because of its heat-producing property. Excessive consumption of grapes can be toxic due to its high levels of resveratrol (2). Also, do not over consume dry grapes (raisins).
