Today, I'd like to enlighten you about the health and wallet benefits of eating grass fed beef. First I probably should explain that the majority of beef raised in the United States is NOT grass fed, but rather corn fed. Corn makes cows grow faster, but in an unnatural way. Additionally, corn is not what a cow's stomach can digest naturally.
Our high school biology classes taught us about the four parts of the cow's stomach. How the cow and other herbivores ate their food, took it to part one & two of their stomach to digest, regurgitated it to chew the cud a bit longer then sent it to part three & four of the stomach. Rumination is an adaption by which herbivores can spend as little time as possible feeding (when they are most vulnerable to predation) and then later digest their food in safer surroundings.
Cows are biologically programmed to digest grasses in such a manner. Corn is not a grass, and therefore bypasses the rumination process. Corn fed cattle grow faster and less naturally than grass fed. A typical corn fed calf is ready for market several months earlier than a grass fed calf. With such efficiency, why does Our Daily Green encourage grass fed meat? Beef from corn fed cattle is about 4 times higher in fat as well as contains virtually no Omega*3. Grass fed beef contains no unnatural growth hormones and additionally is generally slaughtered one animal at a time. (If you've ever wondered about the high number of eColi or mad cow disease outbreaks, they are the result of hundreds, even thousands of animals being factory processed in a single batch. if one cow is sick, the entire lot of meat *especially ground meat* becomes contaminated).
