When I first became aware of grass-fed beef, I was only superficially aware of the importance of omega-3 fatty acids. I have now grown to appreciate that balancing the optimum amount of omega-3 is one of the most important things you can do to stay healthy.
Most nutritionists don't yet realize that the amount and the ratio of omega-6 to omega-3 control much of our disease and health outcomes.
That is why it is so important to consume animals that are primarily eating grass. These animals will have far lower levels of the potentially dangerous omega-6's.
The practical way to do this is to consume free-range chickens and turkeys and pasture or grass-finished beef. Unfortunately, you cannot buy this grass-finished beef at your local grocery store.
Obtaining free-range poultry is relatively straightforward, but you must be careful regarding the beef. Many stores will advertise grass-fed beef, but it may not be grass-finished. They do this as ALL cattle are grass-fed, but the key is what they are fed the months before being processed.
You will need to call the person who actually grew the beef, NOT the store manager, to find out the truth.
The least expensive way to obtain authentic grass-fed beef would be to find a farmer who is growing the beef, which you can trust, and buy a side of beef.
An inexpensive yet effective way to determine if the meat is really from a grass-fed animal is to purchase ground beef. Slowly cook the beef till done and drain and collect all the fat. Grass-fed beef is very high in omega-3 fats and will be relatively thin compared to traditionally prepared ground beef.
It will also be a liquid at room temperature as it has very few saturated fats, which are mostly solid at room temperature
