    Wow, never even thought of this, and I guess neither do most people. Thanks!

    I wonder how well all of these phytochemicals do with various forms of cooking processes, seeing as studies have only been done for a few of them, such as lycopene? Does anyone have any information on this?

    Hi Dr. Greger, I was just wondering if the juice was standard bottled/tetra pack juice or was it fresh pressed. I assume that fresh pressed would be best but I’m hoping packaged juices hold some benefit because they are obviously much more accessible!

    I love your videos!!! I’m hungry for health information!!

    Hi Dr. Greger – I am just wondering how the phytonutrients compare in organic and non organic foods – thank you :)

    I am a bit confused about the benefits of fruit or vegetable juice. I have seen some posts that insist that they ARE basically little more than sugary water and that the only real way to get benefits from fruits and vegetables is to eat them in their natural state, not as juices that have much of the nutrients (fiber, pulp, etc.) removed. So should I consider something like orange juice, tomato juice and apple juice “healthful” or not? Thanks …

    This site says that only 3% of the beta carotene is converted to the Vitamin A the body needs. Which means you would have to eat a lot, really a lot, of vegetables to meet the Vitamin A requirements.

    Could you please suggest a good Mouth wash that prevents tooth decade/cavities or kills bacteria and where it is available ? Thanks!

      Naresh: There is a very interesting video about green tea that is coming up on NutritionFacts and that has to do with your question. Stay tuned!
