I haven't found it yet.
But how do you back up your statement about zinc and copper in "all vegan protein sources" then?
Weston A. Price, who died in 1948, somehow dedicated his life to give vegetarian diets a bad reputation. On the site holding his name, there's someone who refers to a book about fatigue, and claims that "
vegans, who often combine plant protein sources to increase protein intake, can be especially susceptible to copper toxicity". But vegans don't need to combine plant protein sources, we we already know a little about the reliability of that statement. That protein theory was launched by a woman who later apologized for not knowing what she was talking about.
And the book by Ann Louse Gittleman isn't impressive either - I just had a look at it on Amazon, and the book is feeding that old myth from the 70s too: Vegan diets are "low in protein" etc.
That same book also mention that vegan diets (as if there was only one type of vegan diets), was low in zinc, and while both vegans and non-vegans need to pay special attention to some minerals/vitamins (but not the same ones), if you feel that you need more zinc, why is a supplement "the only way" you see? Non-vegans eat cod liver for Omega-3 and what not, so nothing's wrong with eating pumpkin seeds to increase the zinc levels (if you need it).
Vegans who use multivitamins containing copper could be in trouble - not only do they not need multivitamins with copper (better to get copper from food), but the copper in multivitamins is known to damage the B12 in the same multivitamins. And what if the copper in water tubes affect us the same way?
Copper overload may caused by various factors: stress (!), copper compounds added to drinking water, amalgam and gold fillings, birth control pills, soy products (which we don't need) - and: too low zinc (and manganese?) levels, which is why it's important to eat vegan sources of zinc.
Gittleman, by the way, was vegan for a year at college, and ended up noticeably weak, constantly craving sweets, her kin covered with acne and her hair falling out, according to herself. and as a result, she says "My body was telling me in no uncertain ways that it was starving for zinc!". In general, she isn't a very convincing source... what about this one, from the same book: "If you became a vegan for philosophical than dietary motives, you need to reevaluate your reasoning". She probably isn't interested in reading about vegan body builder, about people hove are doing very well on a vegan diet after decades, vegans with olympic medals etc. And when she writes "I had acne when I was in college as a result of my strictly vegan diet"... where 's the logic? If eating vegan as such should cause acne (many vegans report major skin improvements), why aren't all other vegans getting acne?
Bottom line: Don't trust the Weston A. Price site who refers to such a useless source. And if others have told you that you need supplements to get good zinc levels when eating vegan, ask for sources. ANd please don't get this wrong: I'm not ignoring that copper overload may exist (in both vegans and others) - for a number foe reasons.
I decided to switch back, and stop veganism.
I just discovered that you wrote this some weeks ago... what made you want to stop eating vegan then?
