Here in Japan, you can buy whatever kinds of raw fish you like. It almost always has ginger and/or wasabi. Beef is also served raw. I had some that tasted like it was the most tender roast I have ever had, and I've had some that was a little tough. I have also had rare chicken here.
I don't advocate eating most American meats raw. The fish and beef and eggs here are specifically sold to be eaten raw. They are butchered and sold to be eaten the same day. Japanese use many less toxins and preservatives and don't feed their food animals nearly the disgusting things that Americans do. The Japanese are meticulous about cleanliness as well.
If you have some meat that you intend to eat raw, smell it. It should not have any smell at all. When I return to the US, I don't plan to eat any raw meats that aren't organic/grassfed or wild fish.
In my experience raw meats and eggs are so much easier to digest than cooked. After eating raw meats for so long, when I even eat a cooked egg, I feel a little sick to my stomach - and it tastes rubbery and dry. I think raw quail eggs are very good with a little cayenne and Sea Salt . I still eat cooked meats sometimes, but I'd rather have quality raw meats.
I've had salmon that I soaked in lemon juice overnight. It tasted, looked, and had the texture of cooked salmon. I don't know if the lemon juice denatures the proteins or does anything else that would make it less digestible (almost - less raw)?
I do a parasite cleanse every year or so, but have never seen any worms or anything come out of me. I think it's funny when the other Americans get grossed out at the thought of eating rare chicken or raw beef - but they have no problem eating a big mac and a biggie diet soda. I'll take my chances with the parasites - I am not a germ-aphobe, but I am a toxin-aphobe. When I look around and see 90-something year old Japanese people walking around everywhere and then 30-something huge americans struggling along talking about their health problems, it's not difficult to know who's eating stlye is healthier.
Japanese also eat a much wider variety of fresh fruits and veggies than Americans do. When I go to the grocery store or produce stand, I am amazed at the variety - it's not just "have a salad with you meal" (in fact, lettuce is not commonly eaten on a regular basis).
