Dear teacher,
The pasture principle isn't limited to fowl. Compared to most American beef, which is raised on a grain-intensive diet, pasture-fed beef offers 400 percent more vitamin A and E. It is also much richer in beta-carotene and conjugated linoleic acids, all of which inhibit cancer. It's also higher in omega-3 fatty acids, which are a major inhibitor of heart disease. These benefits don't exist at these levels in animal that are fed an unvaried and unnatural diet.
The pasture principle can be applied to vegetables as well. We don't live off the food we eat - we live off the energy in the food we eat. So while Mom asked us, "Did you eat your fruits and vegetables?" today we might well ask: "What are our vegetables eating?"
Q : What does the bold part mean in the context? Why did he say like that?
