Suze, do you happen to know how much selenium liver

contains? And copper and zinc, for that matter.

Selenium is beneficial at rather high levels

Roman, just go to the USDA database to find info like that:

http://www.nal.usda.gov/fnic/cgi-bin/nut_search.pl It's the only source i

know for nutrient analyses, although you have to kinda sorta take the

numbers with a grain of salt because they neglect to tell us what type of

diet the animals (whose tissue they got the data from) consumed. Although,

with the New Zealand lamb, I'd think they would be grass-fed.

Here, I did a quick comparision on a few things. I just used muscle tissue

that I think may be commonly eaten, although the levels of various nutrients

will vary between parts of the body and tissue samples, I imagine.

100 g serving

Lamb liver, raw: 82.4 mcg SELENIUM, 6.979 mg COPPER, 4.66 mg ZINC

Lamb - domestic, shoulder, blade, separable lean and fat, trimmed to 1/8 "

fat, choice, raw: 19.6 mcg SELENIUM, 0.098 mg COPPER, 4.40 mg ZINC

Lamb - New Zealand, imported, frozen, shoulder, whole (arm and blade),

separable lean and fat, raw: 2.6 mcg

SELENIUM, 0.081 mg COPPER, 2.80 mg ZINC

Beef, variety meats and by-products, liver, raw: 41.3 mcg SELENIUM, 3.339 mg

COPPER, 3.92 mg ZINC

Beef, round, top round, separable lean and fat, trimmed to 1/4 " fat, all

grades, raw: 20.3 mcg SELENIUM, 0.078 mg COPPER, 2.70 mg ZINC

Even though we can't put full stock into these specific numbers, you can get

an idea of how much more selenium and copper are found in liver as opposed

to muscle tissue. And also, I should mention that kidney in fact, has more

selenium than liver. The database lists 100 gs of lamb kidney as having

126.9 mcg selenium. No mention of whether the number is for domestic or NZ

lamb, though. Beef kidney is 148.8 mcg per 100 g.
