Pineapple and Grape Juice

There is a big buzz about the IVF community about the benefits of eating pineapple including the core and drinking grape juice before and after egg retrieval and egg transfer. There is plenty of testimonies on all the IVF and TTC message boards. But it is very hard to find any solid scientific evidence on why it works.

In “The Infertility Cure” Dr. Randine Lewis suggests eating pineapple for the enzyme bromelain, which helps implantation.

At BabySnark supplements and tips web site spells out some of the same information that I have found.

"Grapefruit Juice Usage: I researched grapefruit juice and could find nothing anywhere supporting the various claims that it helps to increase cervical mucus and/or helps a fertilized egg to implant. I believe this to be an old (or new!) wives' tale. Grapefruit juice is rich in calcium, potassium, vitamin A and vitamin C, and is of course somewhat high-carb due to the fructose (fruit sugar).

Recommended Dosage: However much you feel like it, unless it gives you heartburn!

Food Sources: Grapefruits.

Side Effects: If you drink too much of it, you might get heartburn. You might also find yourself having to pee a lot if you drink a lot. Heh heh...

Pineapple Juice Usage: There is an old wives' tale floating around that pineapple juice will help a fertilized egg implant. However, pineapple juice is not recommended for use in TTC and/or pregnancy. In large doses, it can cause uterine contractions and bring on spontaneous abortions (miscarriage).

Recommended Dosage: Drink only in small quantities, if at all.

Food Sources: Pineapples.

Side Effects: Large doses may cause uterine contractions, miscarriage, vomiting, diarrhea, skin rash, very heavy menstrual periods. Unripe pineapple is poisonous, causing excessive diarrhea."

I have found more web sites that state that eating pineapple core is only a wives tale and should only be eaten in moderation. There is more information that eating an excess of pineapple can actually cause the uterus to contract and cause miscarriage. If you plan to eat pineapple, eat it sparingly, only 1/5 of the pineapple a day.

As for grape juice, it is another really good antioxidant and can help clean the body, but there is no proof that I could find that it helps with fertility at any stage. It is best to drink the unsweetened juice to receive the most benefits of antioxidants.
