And I will send grass in thy fields for thy cattle, that thou mayest eat and be satisfied. Deuteronomy 11:15.
"Consumers have been led to believe that meat is meat is meat. In other words, no matter what an animal is fed, the nutritional value of its products remains the same. This is not true. An animal's diet can have a profound influence on the nutrient content of its products.
The difference between grainfed and grassfed animal products is dramatic.
Grassfed products tend to be much lower in total fat than grainfed products. For example, a sirloin steak from a grassfed steer has about one half to one third the amount of fat as a similar cut from a grainfed steer." (Click to read more on The Health Benefits of Grass Farming, Author: Jo Johnson)
