    What do you think about the ratio of zinc/copper in the diet? Iv read the ideal is 8/1 but that seems pretty much impossible on a plant based diet, thoughts?

    My zinc levels are low. I eat walnuts and flax in my oatmeal, and black beans or potatoes or grains with steamed broccolli, kale, etc., vegetables.

    Is there a quality supplement that will up the zinc level?

    I heard you need to keep a 10 to 1 ratio of zinc to copper. Is this true?

    My wife was recently diagnosed with having very high levels of copper. What are the chances that her mostly vegan diet has contributed to this problem. There is a lot of hype about copper-zink imbalance in a vegetarian and vegan diets. Although high in zinc, nuts and beans are also generally high in copper. Is this fact or fiction?

      Since no one has answered you yet, I will. Yes, nuts, seeds and beans are generally high in copper–and while the phytic acid in those foods binds their zinc, calcium, iron and other minerals, their copper is still available to us for absorption. As you probably know, high copper can make you tired and fuels the spread of cancer. I also read recently that it may be linked to Alzheimer’s.

      Here’s the long version of the copper-zinc connection and some suggestions on how to increase zinc and lower copper: http://eatandbeatcancer.wordpress.com/2014/03/01/anti-cancer-diets-and-the-pitfalls-of-plants-part-1-copper-and-zinc/

    I am concerned about cadmium levels in zinc supplements. I have read that zinc orotate is the most bio-available type, but is it a good source of low cadmium zinc? I have also read that zinc gluconate has the lowest levels of cadmium but also low absorption. Which would you recommend Dr Greger? Thank you!

    How much beans, nuts and grains should be eaten?
