Compared to just drinking water all day long; grapefruit juice provides a good alternative drink choice. Yet is drinking it really healthy for you when you have type 2 diabetes? On an on-line article published by; they state that rats given grapefruit juice and Metformin helps lower glycemic levels but causes lactic acid levels climb to very high. Thought this study was done on rats in Africa, would the same hold true for humans that are taking Metformin?

I also take BP meds and it says not to drink grapefruit juice or eat grapefruit. It really sucks because I liked grapefruit

I take Simvastatin for cholesterol, and the pill bottle itself says to avoid all grapefruit while taking the medication. So I'd definitely say it depends on the medications you're taking, and if you're concerned talk to your doctor… they'll be able to help you out. :)

I asked a RD and she said that just taking pills/medicine for Diabetes alone does not have any effect with drinking grapefruit juice. Thought If you are taking pills/medicine that i helping you with high cholo, its not good for you.

My dad's doctor told him that it was dangerous and he should stay away from grapefruit juice, but didn't actually tell him why. I'm glad someone posted this, so now I can share this information with him. Thanks, guys!

I was told that is was my blood pressure medicine that grapefruit interacts with. I asked my doctor if I could eat a grapefruit in the morning since I took my lisinopril at night and he said no. So it is off my menu completely.

You have a bunch of different factors really. A cup of grapefruit juice has about 25g of carb in the form of sugar, just like most juices. That will raise blood sugar and raise it significantly for most people. Then you have the interaction with statins which are commonly prescribed to diabetics. As to the study you post, who really knows. So many things that are proven in rats and mice never come to anything when done on humans.
