      How does dry kale compare with fresh or frozen kale?

  • Do you have a ranking of healthy foods per serving? This would be most helpful. Even more helpful to me than per calorie or by weight.

    Why did pecans, but not walnuts, make the ‘antioxidants per serving’ list? Do walnuts have that much less mass/volume compared to pecans? How do the two compare on omega-3/6 ?

    Might this not be a case where a supplement is beneficial? Swansonvitamins sells 100 ground clove 450mg capsules for $6.49. I’m not sure how much a “pinch” is, referring to a later video, but I assume it is less than 450mg.

      Well, I’ve been adding about 1/2 to 1 teaspoon of ground cloves to my dark berry mixtures 3 or 4 times a week, along with my oats…takes some getting used to, for sure, but it is doable, just saying!

        Im doing this with cayenne and ginger and its good!

    After viewing this video, I accidentally found the following article stating that ORAC Tests are useless. The URL is listed for you to read the entire article. Am I missing something?

    USDA Says ORAC Tests Useless, Removes Database for
    Selected Foods

    June 12, 2012 0 Comments

    WASHINGTON—USDA’s Nutrient Data Laboratory (NDL) removed the USDA Oxygen Radical Absorbance Capacity (ORAC) Database for Selected Foods from its website due to mounting evidence that shows the values indicating antioxidant
    capacity have no relevance to the effects of specific bioactive compounds, including polyphenols on human health.

    So long as we are talking about cloves I should ask for opinions about eugenol, a little known compound in cloves and, to a lesser degree cinnamon. It was once speculated it could be carcinogenic.

    I have watched this video 5 times on here and on YouTube but i still don’t see the top 12 list. On YouTube, your voice is much slowed down and softer. I wonder if someone messed with your video?

    • 2tsaybow

      Yes, that is because the top 12 antioxidants are listed in the next video; Antioxidant Content of 300 Foods.

    Got kidney stones from, I believe, 2 years on a super food smoothie. I cannot find the oxalate content of Acai or pomegranate. Have eliminated strawberries, kale, blackberries, raspberries, sesame. Kept hemp, coconut, red palm oil, walnuts, pumpkin seeds, blueberries, chia, sunflower seeds, tart cherry concentrate, pom concentrate and 4-5 raw veggies. info? advice?


    Hi Dr. Greger and company,
    Recently I’ve been adding about 1/8 teaspoon of ground cloves to my coffee. If I might ask, could you address questions of what is an effective level of clove consumption and what, if any, potential adverse affects there might be: what level works and what is the safe upper limit? Thank you much.

  • Arthur Robidoux

    To make a smoothie what would be the better antioxidant red
    cabbage or amla powder

  • Josephine Kwan

    Do cloves have any adverse effect on anemia patients? I have recently discovered this spice and thoroughly enjoy making my own cloves tea. I hope it is ok to consume. Many thanks!
