Doctor's Note

What sports physiology revolution am I talking about? See yesterday’s video, Doping with beet juice. Daily viewers of NutritionFacts.org may recognize nitric oxide, featured a few weeks ago in The power of NO. If bacteria on our tongue play a critical role in this process, what would happen to vegetable-enhanced athletic performance if we made the mistake of swishing with an antiseptic mouthwash? Find out in tomorrow's video, and in the meanwhile please feel free to check hundreds of my other videos on more than a thousand subjects. And happy Valentine's day everyone! Check out my blog post Atkins Diet and Erectile Dysfunction for tips on extending one's love life as well as the life of your love.

For more context, please check out my associated blog post: Using Greens to Improve Athletic Performance.

    I’m assuming the proton pump in this video is not the acid producing proton pumps we have in our stomachs, right?

    • Dana Razzano

      Hi MacSmiley,

      Good question. He is talking about the proton pumps that are present in the electron transport chain in the inner membrane of all of our mitochondria (the powerhouse organelle of the cell). These pumps are what keeps the ATP factory working and producing, day in, day out. The proton pumps in your stomach are similar in that they are utilizing hydrogen as well, but for a completely different purpose. Hope that clears it up!

    I love the film clips you’ve inserted in your videos the last couple of days: the chest with the beating heart yesterday and the ATP-synthase animation today. Kudos and Great job!

    Would taking the powered beet pills have the same effect? Love your videos.

    How much beet juice should we drink per day?

    What about the oxalic acid in beets? Is it good for you to take in large amounts?

    • Michael Greger M.D.

      As noted in my video about the oxalates in turmeric versus cinnamon (Oxalates in Cinnamon), it’s not just the amount that matters but also how well particular oxalates are absorbed, and the bioavailability of oxalates in beets is relatively poor (6 times less so than spinach, for example). Cooking the beets could cut levels about 25% but for the rare person with a condition like idiopathic calcium nephrolithiasis (a type of kidney stones) that needs a low-oxalate diet, a better high-nitrate vegetable choice would be arugula.

    Thank you Dr.Greger :)

    I read in the book “The Nitric Oxide (No) Solution” that kale is the top source of nitrates, far better than beets. I wonder if with kale one gets the same effects as with beets, perhaps improved proportionally?

    Dear Dr. Gregar, excellent video..as always. However I wonder could you the source of the diagram shown at 1:05? It shows the systemic metabolism of nitrates & nitrites?

    Many thanks…

    Your website is really slow. I have watched videos here before. It’s a great site, but today I can’t watch anything. Are you having issues?

    Dr. Gregor, A bike-racing friend of mine now swears by beet juice and has a juicer ready at all his race venues. But I just found bottled beet & purple carrot juice in the grocery store. Will pasteurization ruin the beneficial effect, and if so, is it know by how much? Sure would save time and compost if a partial substitute for home-juiced.
