Zinc

Seems most of us get plenty of zinc in our diets and that the zinc we do get is usually well balanced by our intact of other metallic minerals,

Foods with particularly abundant amounts of bio available zinc include:
oysters
beef pot roast
ground beef
turkey
pumpkin seeds

Zinc, Zinc, in the Pink

What are some excellent natural sources of bio-available zinc?
Zinc supplements I've seen do not appear very bio-available and I'd like to avoid them.
What I'd like to have well in mind is a small menu of foods that typically contain high amounts of available zinc.
I understand that pumpkin seed husks contain a great deal o zinc, but I'd like more variety than that offered by husks. One item doesn't make a menu.
Have you heard of foods high in zinc that you would care to tell me about?

Why am I interested? Because:
Lack of zinc may lead to angina and I have experienced angina.
Lack of enough zinc may lead to enlarged prostate and I have experience enlarged prostate.
I have told I have atherosclerosis or similar circulatory problems including calcium deposits and some health professionals believe that they have fund evidence of a good cheating effect of zinc.
Zinc lozenges have stopped a cold developing within me.

Exercise Is Probably More Effective

I think that I can profit from more zinc in my diet.
Why?
I've heard that many Americans lack sufficient zinc.
I have experienced angina for which zinc is prescribed.
I have experienced prostate enlarging for which zinc has been indicated,
Polish zinc miners have an unusually low incidence of angina.
MDs have lowered angina in their patients with high dosages of zinc.
Some believe that they have evidence for a chelating effect from zinc which reduces hardening of arteries.

I'd like to have a good menu of foods high in zinc. I've heard that pumpkin seeds are high in zinc, but also hear that most of the zinc is in the husks. And, pumpkin seeds don't make much of a menu.

It would be wonderful if you could tell me of a food high in zinc.

Oh, by the way, when I did have exercise induced angina, I got rid of it by jogging to the point of pain and then changing to a walk until the pain receded and then jogged to the point of pain again. I don't remember how long it took until my pain was gone, but feel sure that it was much less than half a year.
