Grass-fed beef has more beta-carotene, vitamin E and omega-3 fatty acids than beef produced using conventional feeding strategies.

That’s according to a research review by the University of California Cooperative Ex-tension and California State University, Chico. Researchers reviewed 55 articles and other information. They concluded that ranchers who produce grass-fed beef may right-fully claim the product is more healthful than conventionally produced meat.

Compared with cattle finished on grain, grass-fed animals have leaner, less tender meat that contains higher nutrient levels. It also can bring higher prices.

“Grass-fed hamburger meat sells for about $1 more a pound,” says Glenn Nader, farm advisor in Sutter and Yuba counties. “Steaks are sold at about double the normal price, or about $7 more per pound than ordinary beef.”

However, because of the higher cost, the market is limited to a certain type of con-sumer.

“These products sell in natural-food stores that attract high-income, health-conscious consumers,” says Nader. “We don’t think grass-fed beef is a wave of the future. It represents a small niche market that we’re trying to make available to ranchers.”

The California researchers found that 3 oz of ground beef from grain-fed cattle contain about 41 micrograms of beta-carotene and a typical ribeye steak has 36 micrograms. Meat from cattle fattened predominantly on ryegrass has almost twice as much.

The amount of vitamin E in grass-raised beef is 9.3 micrograms/gram vs. 3.7 micro-grams/gram in beef from high-grain diets.

Cattle fed primarily grass have 60% more omega-3 fatty acids and a more favorable omega-6 to omega-3 ratio. Omega-3 fatty acids reduce inflammation and help prevent heart disease and arthritis, while omega-6 promotes inflammation, blood clotting and tumor growth.

In addition, raising cattle on grass boosts the beef’s level of conjugated linoleic acid (CLA), which is credited with numerous health benefits.
