The difference between grainfed and grassfed animal products is dramatic.
First of all, grassfed products tend to be much lower in total fat than grain fed products. For example, a sirloin steak from a grass fed steer has about one half to one third the amount of fat as a similar cut from a grain fed steer.
In fact, grassfed meat has about the same amount of fat as skinless chicken or wild deer or elk. Because grassfed meat is so lean, it is also lower in calories.
Although grassfed meat is low in "bad" fat (including saturated fat), it gives your pet from two to six times more of a type of "good" fat called "omega-3 fatty acids."
- Omega-3 fatty acids play a vital role in every cell and system in your pet's body. For example, of all the fats, they are the most "heart friendly."
- Omega-3s are essential for your pet's brain as well.
- Another benefit of omega-3s is that they may reduce your pet's risk of cancer.
In animal studies, these essential fatty acids have slowed the growth of a wide array of cancers and kept them from spreading.The reason that grassfed animals have more omega-3s than grainfed animals is that omega-3s are formed in the green leaves (specifically the chloroplasts) of plants. Sixty percent of the fat content of grass is a type of omega-3 fatty acid called alpha-linolenic or LNA.
When cattle are taken off grass and shipped to a feedlot to be fattened on grain, they lose their valuable store of LNA as well as two other types of omega-3 fatty acids, EPA and DHA. Each day that an animal spends in the feedlot, its supply of omega-3s is diminished.
The CLA Bonus
The meat and milk from grassfed ruminants are the richest known source of another type of good fat called "conjugated linoleic acid" or CLA. When ruminants are raised on fresh pasture alone, their milk and meat contain as much as five times more CLA than products from animals fed conventional diets.
CLA may be one of most potent defenses against cancer.
