While Kobe beef is one of the highest-profile fakes, far more prevalent are retailers passing off grain-fed beef as grass-fed. One way to tell the difference: True grass-fed beef has a deeper, darker red hue than grain-fed meat, and little marbling. It's another reason to buy your beef from a butcher or farm when possible versus the local supermarket.

The majority of salmon is farmed, Olmsted says, yet retailers often sell "wild" next to farmed for $2 more a pound even though it's the exact same fish. To circumvent this fraud, look for Alaskan salmon, which is caught in the wild. And buy shrimp from the Gulf of Mexico; if it's packaged, it should have the Gulf Wild logo.
