I eat just about anything -- meat, dairy, grains, any fruit or vegetable out there. Obviously I try to eat mostly unprocessed foods, but I eat a little bit of "junk" regularly (candy, alcohol, fast-food french fries, whatever).
I take:
multivitamin (generic brand, usually)
B-complex for energy
slow-release iron
I started the iron by my doctors recommendation, and after a few years they decided I didn't need it. But about 6 months ago I was really lacking energy and started taking it again, and I feel a difference. Just wanted to explain, I don't recommend taking iron without asking your doctor! It can have some digestive side-effects and hardly anyone needs extra anyway.
I've tried to take calcium, too, but I just can't remember to take vitamins more than once per day!! And it doesn't do any good if I take it at the same time as my multi, since that already has as much calcium as I can absorb at once.
