Beef Patties (4 x 150g) - Free Range & Grass Fed Beef.
Many studies show that nutrients in beef vary a lot dependent on what the cow eats.
Grass-fed cows eat (mostly) grass, while grain-fed cows eat (mostly) an unnatural diet based on corn and soy during the latter part of their lives.
To maximize growth, the grain fed cows are often given drugs, such as antibiotics and growth hormones.
Grass-fed beef usually contains less total fat than grain-fed beef, which means that gram for gram, grass-fed beef contains fewer calories. However, the composition of fatty acids is also different:
Monounsaturated fat: Grass-fed beef contains much less monounsaturated fat than grain-fed beef.
Omega-6 polyunsaturated fats: Grass- and grain-fed beef contain very similar amounts of omega-6 fatty acids.
Omega-3s: This is where grass-fed makes a major difference, containing up to five times as much omega-3.
Conjugated linoleic acid (CLA): Grass-fed beef contains about twice as much CLA as grain-fed beef. This fatty acid is associated with a few health benefits.
Nutrition: Conventional grain-fed beef is highly nutritious, but grass-fed beef contains more carotenoids, vitamin E, and other antioxidants.
