I eat raw chicken breast now and again, when I feel anemic. I freeze it and then defrost it in the microwave, before I eat it, as I find the microwaves kill off bacteria.
I studied microwave effects on a tardigrade colony, and found when exposed even to small amounts of radiation, it drastically affected the population and decreased their numbers.
I don't recommend eating raw meat to everybody, as some raw meats contain parasites, if they aren't properly stored etc.
However, raw chicken breast and raw lamb, I do like on the odd ocassion. I will pour vinegar and Worcesters sauce on them prior to eating them raw. I have never suffered any ill effects as a result, but I don't recommend this practice for everybody.
My nanny when I was younger told me that either during WW2, or when she was a young girl that the doctor told her to eat chunks of raw beef, as at the time, she was severely anemic. It was through her that I found out that it was common practice in her day to treat anemia.
She was born in 1903, so that gives you some clue. Also, her doctors would have been born or raised in the 1800's long before the ferrous pills came out. (iron pills).
She lived well into her 80's, before she was taken from a bout of pneumonia.
