"Many women and acupuncturists swear by pineapple's ability to help with implantation. For one thing, the bromelain in pineapple, which is a nutrient that it contains in higher concentration than pretty much every other food, is said to be an anti-inflammatory and also to increase cervical mucus. The increase in cervical mucus can make the uterus more "sticky," which can lead to increased rates of implantation. The most bromelain in the pineapple is found near the core, so many acupuncturists and natural therapists recommend eating the whole pineapple including the core.
One thing to note, though, is that there is also some evidence that pineapple juice in high quantities can cause cramps and can even cause spontaneous abortion. There's pretty much no danger of this if you eat just a cup of actual pineapple each day - which will be less concentrated than the juice squeezed out of the pulp. Just be sure that you keep things in balance and don't overdo it."
