What is the correct ratio of Copper to zinc?

Commented on May 16, 2014

am I supposed to have more zinc than copper? I've been supplementing 15 mg zinc without coppes, just assuming I'm getting the copper from my diet, but I don't wanna throw anything off balance and I don't get how they compete with each other?

I am eating a table spoon of frozen liver, most breakfasts. It does not taste like much when it is frozen, and I always have potato or rice to help it down.

Yes, it is in fact larger than the true ratio of muscle/liver in bovines. We lose significant zinc by skinning the animal and discarding the hooves. Whole chicken is more balanced, if you eat the skin, even though chicken breast has little zinc by itself. Eat them whole!

USWellness meats has some very tasty liver sausages that don't taste anything like live. A few of them are even raw/uncured.

Look at that mass ratio… much closer to the ratio of liver in the actual animal versus paleo recommendations to eat liver weekly or more.

I've been looking at recipes for terrines. Basically meat loaf with cut-up liver in the heart. Chicken liver is good, duck is better, goose is best.

Beef liver in meatloaf. Chicken liver in pasta sauce (yes, I eat pasta, specifically just to get my liver down).

Don't know where Kresser gets that ratio, that would induce copper toxicity in short order. Copper induces toxicity in much smaller doses than does zinc.

thank you all so much! Yeah Kresser's pod cast had me worried!

I can't get over the smell and taste of liver though!

A 50/1 intake of beef meat /beef liver will give you an approximate Zn/Cu of 10 or so.

It's approximately 10 mg of zinc for 1 mg of copper. We don't need that much copper, many folks are deficient though. And of course, individual needs can vary significantly. I happen to need much higher consumption of copper than average, though it might be because I have low selenium in my diet because local foods here are grown in/on selenium deficient soil.

It's all interrelated, I'd recommend NOT supplementing zinc, most folks do get enough of that from diet.

see: http://www.westonaprice.org/metabolic-disorders/copper-zinc-imbalance

and: http://chriskresser.com/rhr-could-copper-zinc-imbalance-be-making-you-sick

Seems you want 0.1 to 1 ratio. (EDITED)

But, if anything, just eat some dark chocolate, grassfed beef liver, and shellfish and don't worry too much over it.

Since you're taking double the rda for zinc, then maybe double the rda for copper? 15mg isn't very much zinc, as such worrying about cu:zn ratios is unlikely to even be worth it in this case. You'll get most of the copper you need from diet alone.
