Grass-fed beef: What are the heart-health benefits?

Possibly. What cattle eat affects the nutrients and fats in different types of beef. Grass-fed beef generally comes from cattle that eat only grass and other foraged foods throughout their lives.

Often, conventional beef cattle eat a diet that includes grains, such as corn, at some point. When compared with other types of beef, grass-fed beef may have some heart-health benefits. Grass-fed beef may have:

• Lower total fat content
• More heart-healthy omega-3 fatty acids
• More omega-6 fatty acid (linolenic acid)
• More antioxidant vitamins, such as vitamin E

However, grass-fed beef and conventional (grain-fed) beef both contain saturated fat. Such fat has been linked to unhealthy cholesterol levels. The American Heart Association recommends limiting saturated fat.

When choosing beef — whether it's grass-fed beef or another type of beef — opt for lean beef (10% fat or less). Grass-fed beef is generally more expensive than conventional grain-fed beef. Also, there is limited long-term research to definitively prove that grass-fed beef is better for you. Talk to your health care provider or dietitian if you're thinking about adding more lean beef, including grass-fed beef, into your diet.
