Doctor's Note

For an explanation of this boost in the mitochondrial efficiency of human energy extraction, see Priming the Proton Pump, the second in my video series on the performance-enhancing effects of vegetables. What might be the potential downsides of doping with beets, or other nitrite-containing vegetables? Stay tuned for Asparagus Pee.

    So, let’s say that I’d like to apply this research to myself. How much should I drink? How often? When? 2 cups, before running, perhaps?

    • Toxins

      The participants in the study drank a glass of beat juice 2.5 hours before the activity.

     hahaha I just dried to chug beet juice, ive had beet juice before (but never alone) and had few side effects except red poop. I drank about half a liter and first I wanted to see my tongue, I was sure it was going to be super red and it was! and about 3 seconds later uhh ohh…i guess it wasnt such a good idea. It came out of me twice as fast as it went in and had me running to the bathroom! any studies on beet juice and a clean colon? ahahah luckily nothing too bad

  • Rudy Belgardt

    I’m just wondering if pickled beets have the same effect. Does the act of pickling in some way reduce the efficacy of the good stuff?

    Hi Dr. Greger,
    In additoin to beet juice, Vegan triathletes like Rich Roll are also using cordyceps and maca for endurance, and the recent book “Eating on the Wild Side” by Jo Robinson mentions watercress for aiding recovery from strenous exercise. Do you have any views on these?

    I’m an elite cyclist and use Beetroot juice before races most of the time, thanks for sharing this info with us Michael. I’be been Vegan for almost a year now and have never felt better. I’d be interested to know if I should be upping intake of certain things to account of the amount of exercise I do.

    Should I be having more protein than the average person doing recreational exercise? If one could look at a perfect healthy diet what would it look like. Is there anywhere online we can see a plan for a ‘perfect’ diet?

    Many thanks.

      In terms of protein, protein needs match caloric needs, so when you exercise, you tend to consume more food, which will inevitably lead to greater consumption of protein. There is no need to seek protein rich foods or to supplement additional protein. I would suggest consuming something containing carbohydrates immediately after physical activity.

      “The Anabolic Phase: The 45-Minute Optimal Window
      The anabolic phase is a critical phase occurring within 45 minutes post-exercise. It is during this time that muscle cells are particularly sensitive to insulin, making it necessary to ingest the proper nutrients in order to make gains in muscle endurance and strength. If the proper nutrients are ingested 2 – 4 hours post-exercise they will not have the same effect. It is also during this time in which the anabolic hormones begin working to repair the muscle and decrease its inflammation.
      Immediate ingestion of carbohydrate is important because insulin sensitivity causes the muscle cell membranes to be more permeable to glucose within 45 minutes post-exercise. This results in faster rates of glycogen storage and provides the body with enough glucose to initiate the recovery process (Burke et al., 2003). Muscle glycogen stores are replenished the fastest within the first hour after exercise. Consuming carbohydrate within an hour after exercise also helps to increase protein synthesis (Gibala, 2000).”

        Isn’t this a myth or was debunked? If normal “broscientists” are saying its fake then you’d think its not true or atleast some reason for people not believing it…

        • Jacob Hafer

          How can a broscientist debunk anything?

  • Joaquin

    Many thanks for the information Dr. Greger , I’m passionate about vegetables but the WHO acceptable daily Intake for nitrate is 3,7mg/Kg/day ( follows link) which results in 300-400mg per day, the same dose recommended by these papers, that worries me a little, what do you think?

    This beet juice actually worked!
    I volunteered with a track team and the athletes drank beet juice three days before and the day of the track meet. All of them did better than before. And even the medicalically fragile kids who drank the beet juice took 2.5 seconds off their times and more importantly were not as fatigued after the races!!!
    Dr. Greger’s book How Not To Die was only the beginning fkr great sustainable health. We watch his short videos, and have all changed to Vegan for life enjoyement for life.
    What i have noticed first hand is far less pain, healing process has spead up, and there is far more enjoyable moments. Thank you for bringing common sense back to Earth.

    With great gratitude
