Regarding beef specifically, we don't eat it often but when we do, it's always grass-fed. Grass-fed beef/products provide real health benefits over grain-fed. Grass-fed products are:
- Lower in fat and calories
- Higher in Omega-3 Fatty Acids
- Richest known source of Conjugated Linoleic Acid (CLA)
Of course grass-fed beef and other grass-fed products cost more. Sigh. In my area, ground beef is typically $2-$3 more a pound unless it's on sale. As I was in line at Whole Foods last week they announced a special on grass-fed beef - $4.99 a pound. If my cart wasn't already half unloaded, I would have picked up my son, ran back to the meat department and grabbed a pound or two. Now that I'm writing this, I probably could have asked the cashier to have someone get it for me. Oh well.
If you haven't tried grass-fed beef, I suggest you give it a shot. You'll taste the difference and benefit from its higher nutritional value. And if you eat beef more frequently, you should definitely make the switch.
