Health Benefits
Research conducted by the University of Manitoba, Alberta and Ontario, Canada, and beyond these borders in the U.S. and in South America, particularly in Argentina and Brazil, strongly suggests that grass-fed (also known as grass-finished or forage-finished) beef contains higher concentrations of Omega-3 Fatty Acids and conjugated linoleic acid (CLA’s) than conventional beef. In fact, research suggests that it may be as high as three times that of conventional grain-fed beef.
We, as humans, cannot manufacture essential fatty acids, therefore, they must be obtained from food or supplements. The research strongly suggests that grass-fed beef has a higher ratio of Omega 3 to Omega 6 Fatty Acids because grass contains a higher concentration of essential nutrients than are in feedlots.
Other studies suggest grass-fed beef contains increased concentrations of beta-carotene and alpha tocerpherol.
Other studies suggest grass-fed beef contains Vitamin E, a known antioxidant. This may have a powerful effect at reducing the onset of certain illnesses by protecting the human body from heart disease, cancer development, cataracts and maintain a healthy immunity.
All of these have a positive effect on human health and nutrition and may lead to better wellness. Yes, lean beef can be part of a healthy diet.
