There is a difference between edible metals and non-edible metals. I thought it was fairly obvious when you stated that why do not we just rely on metals for minerals.
I am sure you can Google. A simply search of side-effects of beef would take you to hundreds of links. You can do the same for every type of meat.
Cancer is not “caused” by anything, if it did, cancer would be curable. Maybe one day we will now what “causes” cancer, and that is when we will start finding a cure.
“Cancer is not caused by lifestyle” is the most ignorant statement you have made in this thread, and that means something because you have set some very high standards.
Certain lifestyles puts you at a higher risk of cancer, and that is why certain products have been classified as carcinogens. Consuming carcinogens - or using carcinogens - puts you at a higher risk of having cancer, and processed meat is a carcinogen.
However, as I said, there is no proven cause for cancer, which is why kids have cancer and some are even born with it, but on the other hand, you have cancer-free people who have consumed pork and processed meat all their lives.
This really is a waste of time, because you are going to come up with something that will make your previous posts look intelligent and informed.
