Transcript

Star fruit, which you can often find in the tropical produce section at large supermarkets. Harmful, harmless, or helpful?
Harmful enough to shut down your kidneys. Acute oxalate nephropathy, caused by the extraordinarily high oxalate content, a condition previously associated primarily with antifreeze ingestion. Nice. Eat an apple.

    I’m curious how applicable these findings are to humans since this study was conducted on rats. Any human evidence out there showing that people should avoid this cute little fruit? Or is your guidance on this one, precautionary based on this rat study?

    • http://nutritionfacts.org/ Michael Greger M.D.

       The phenomenon has been documented in humans. The animal study was just trying to figure out the mechanism.

        Thanks for responding! :)  Looks like star fruit is off the menu.

    The organic farmer I buy most of my food from is always offering me star fruit and saying how good it is for you. I can’t wait to share this insight with her. You are turning me into a nutritional ninja! Thanks Dr. G

    Hi, great site! I’ve just spotted a link stating that green smoothies can cause high Oxelate levels in the body. it sounds like dis-information to me but do you have an opinion on what is being said here? http://www.thehealthyhomeeconomist.com/how-green-smoothies-can-devastate-your-health/

    But spinach is also very high in oxalate content. Should spinach be avoided?

    And even my dear almonds seem to have pretty much oxalate..
