We as a society tend to be sticklers when it comes to doing our research prior to making any "significant" purchases. I draw attention to the word significant though, because I feel our priorities in this area a bit mixed up.
Most people, prior to purchasing a car will do tons of research (especially for a used vehicle) as far as prior owners, usage history (city or highway), accident history, and any major repairs that may have been done. Some people even go to the extent of bringing the vehicle to a mechanic they trust prior to making the purchase. We do the same thing prior to purchasing a home, with all of the documents/certificates we demand, not to mention the home inspector we pay to scrutinize the integrity of any and all major components.
These are all good examples of a smart buyer, but we tend to lack this bit of intelligence when it comes to buying food. Our health is the most important thing we have; it can be the difference between living a long pain free disease free life, and suffering with medical issues our entire life. So why then do most people choose to play the ignorance card when it comes to feeding themselves and their families? Wouldn't it make sense to want to know a little bit about what it is you're consuming on a daily basis. Wouldn't you want to know that the eggs, poultry, or beef you eat come from chickens or cows that were allowed to graze freely on what nature intended them to eat, rather than fed an unnatural diet consisting of meds/synthetic nutrients/ground up animal parts (for added protein and fat)/and corn and grains (especially for cows with a digestive system that is designed to digest grasses).
An unhealthy chicken, cow, or pig makes for an unhealthy person consuming these foods. So don't be afraid to do your research and learn a little bit about what you're about to eat.
