I have eliminated animal products from my diet in order to improve my health by reducing the amount of excess estrogen in my body.
I have not heard this theory. Now fat itself can generate estrogen so if you lose weight there will be less estrogen generated by fat (might be why it's a good idea to have a little bit of chub if one is menopausal - not to be obese or anything like that but .... maybe not to be skin and bones either)

Its working really well and I feel better than I have in a very long time except that I hate eating this way. Food consumption has gone from being a great pleasure to an obligation I wish I could get rid of. I eat because its required of me and I am never truely satisfied for any legnth of time.
Well are you trying to do low fat as well? Because yes that is a pleasureless diet! No animal products and no fat, oh that's a hard one. I guess one could eat non-fat sweets for pleasure, but that's definitely not healthy. If you are allowed fat, look into mediteranian dishes (of course by no means all vegan but a few are - boatloads of olive oil - makes veggies yummy for sure! Veggies cooked with fat can definitely be tasty, bean dishes are better with some fat etc). That said I think having some animal products in the diet is healthier than none. No fish even? You really think fish raises estrogen? Like I said this is all a new theory to me. Animal protein as such?

Feeling better than you have in a long time may not mean you have to be on such a strict diet. If you went from junk food omnivore to health food vegan of course you'll feel better. Maybe just eating more veggies in general helps and you could still have some animal protien here and there. Also you may have had alergies to something like dairy and something like that may be what you really need to eliminate rather than everything.

We fill animals with so many growth hormones and antibiotics to get them to a kill weight as quickly as possible.
definitely think meat raised more healthifully and fed less junk is healthier.

Or if I found a good source of cows milk, can I make yogurt, cheese, and ice cream that aren't so unhealthy?
Well I'm not sure about this but I think to the extent animal products are tied to anything unhealthy I think it's mostly dairy and red meat. Dairy possibly with ovarian cancer. Red meat to colon cancer. Hope others here have more information for you. But of course organic, pasture raised, etc. animal products are much purer than industrial animal products. I have no doubts about that.
