I thought I post about something I read about corn or grain fed cattle versus grass fed cattle. It is interesting because it tells you that we, including all other living creatures on this planet Earth been designed to eat certain foods only - meaning our digestive system is designed for particular foods. Introducing processed food to our or animal digestive system can actually cause potential problems in the later food chain. I don't know how many of you know, or at least I didn't know, but the conventional American cattle is corn or grain fed, as oppose to grass fed cattle. Note that the cattle is designed to graze, therefore, when fed with corn and grain the cow's stomach becomes very acidic environment attracting bacteria like E.coli. The beef from grass fed cattle is much leaner and has more the omega-3 fatty acids than the today's conventional beef. To conclude, you may want to consider then the grass fed beef, which is also classified as organic beef.
