    This is the second video of a three-part series about the latest discoveries on kiwi fruit. See also yesterday’s video-of-the-day Kiwifruit for Irritable Bowel Syndrome. Other ways to protect one’s DNA include eating broccoli, avoiding bacon, not overdoing stevia, and eating a plant-based diet in general. See Repairing DNA Damage and Research Into Reversing Aging.  In tomorrow’s video Plant-Based Diets and Cellular Stress Defenses we’ll see if we can break through that kiwi ceiling! In the meanwhile, there are lots (and I mean lots) of other videos to peruse.

      Dr G is spending just another day at the office exploiting plants and their ability to heal.

      Are there studies that the Kiwi fruit aids in repairing the fetus heart? I am 20 weeks along, Dr. found a possible tiny hole in fetus heart. Not a big deal, but going to stock up on Kiwi’s for their folate and health benefits.

    Is this effect unique to kiwi fruit? Could the same thing happen with red delicious apples, or kale or any number of other plant-based food? (btw, I’m logged in to your site but the comment system asks for yet another login, not even offering the same credentials as the site)

    Do you recommend eating the skin of the kiwi?

    • Dspollock

       I do eat the skin of the kiwi. Following a tip in another on-line forum, I use a vegetable scrubber to scrub the hairs off the skin, slice off the two ends and then simply slice the rest of the kiwi to eat. Earlier research has shown that often, the layer just below the skin is rich in nutrients.

      • Troy

         I don’t bother removing the hairs, but I get organic for fruits I eat the skin of.  The skin is tasty :)

  • Valnaples

    heh, kiwi were 3 for $1 the other day…bought 6…who says eating healthy is too expensive??? (^_^)

  • Eli

    Damnit! Whats with the cliffhanger?

  • Matt

    Were the kiwis organic or conventional? And do you think it matters which? Any research on the effects of organic vs conventional?  Also, what were their diets like aside from including 1 – 3 kiwis a day? 

    • Thea

       I remember one video on this site which shows measurements of chemical’s in kid’s urine before, during and after eating organic.  That study doesn’t directly address whether the chemicals interfere with DNA repair, but I thought you might be interested in learning about the video if you didn’t know of it already. 

      There may even be more studies concerning organic vs not on this site.  I just can’t keep it all in my head.

      Note that I constantly have the same kinds of questions that you do.  You have company in wanting to know the effects of conventional produce on our health.

  • Bet amla works better.

  • Wickedchicken

    That is so interesting that 1 is as good as 3. I rarely eat kiwi, but I will think about adding them (well, 1!). Of course with studies like for example the antioxidant value of all vegetables against cancer, that you so nicely presented, we are spoiled! We get to know all the veg in comparison! So really while a kiwi might be good, is an orange more effective? Are berries more protective? Is 1 apple twice as repair-inducing. I am now used to being spoiled with answers so I need to know it all! LOL! You are spoiling us!! Thank you for all your hard work

    Dr. Greger. Generally speaking, is DNA repair a good thing for someone who already has cancer? The reason for my question is that i’ve been told that cancer is damaged DNA that the body doesn’t recognize as such.

  • MY LIFE ruined by Levaquin

    My DNA has been damaged by Fluoroquinolone Toxicity, from what I understands , adducts to my DNA can never be removed, are you familiar with this topic, Doctor?

  • sydneyboo1

    my dna was severely damaged by 400 pills of flora quinolones cipro and levaquin, I am near death..they abduct to our dna. are you familiar with this and any advice.. I eat organic now for 2 years.. am declining..

    • Norman Frazier

      My thoughts sydneyboo1 is nutritional only. Decrease your acidity with baking soda, increase your peptides with probiotic, increase your vitamin K, B12, E and C to a pharmaceutically significant daily does, and eat protein rich food: eggs, beans, etc. Use 1 to 10 dilution of bleach to water to bath your body. And then Kiwi or concentrate,
