    So enjoyed watching so many of your video’s, learned a great deal..thank you!
    Question-what’s your thoughts on WheatGrass juicing? Healthy or Harmful?

    • Toxins

      Hello Trinda, I believe I can help you with your question. Wheat grass, like many other “super foods” have been touted as a super healthy substance. But like many other “super foods”, they turn out more harm than good. For example, check out the Star fruit, mangosteen and several spirulina videos Dr. G posted People claim they are healthy but they cause many health detriments. But regarding wheat grass, what does the science say on the subject? Well, according to a study done on rats, it lowered cholesterol, could help prevent heart disease, and i quote the “Phytochemical analysis revealed the presence of flavonoids, triterpenoids, anthraquinol, alkaloids, tannins, saponins and sterols in fresh wheat grass juice.” It appears as though wheat grass is rich in antioxidants and is health promoting. Digging deeper, we can see that for pregnant woman, wheat grass in fact controls BPA toxicity very effectively. “our data suggested potential detoxification of wheat sprouts on BPA-toxicity via antioxidative and interference of absorption, distribution, metabolism and excretion (ADME)-mediated mechanisms in young women.” Wheat grass is, as far as the data tells, health promoting! (for more on BPA check out this link as well as Dr. Greger’s video on BPA )

    Hello Dr. Greger. I LOVE your website. Thank you so much for this valuable public service that you provide. It is nothing short of AMAZING!

    On the topic of water- I hear a lot of advice from the holistic community about the importance of drinking water first thing in the morning (not just children, as this video highlights, but everyone in general), but studies are never provided to back up this claim. While this makes sense intuitively, are there any studies to back up this claim?
