The Top 10 Food Frauds

Pomegranate Juice

This antioxidant-rich juice has been touted as heart-healthy, but it’s also expensive.

1Olive Oil

Some oils, extra virgin olive oil in particular, have been caught in the food fraud act. They can be diluted or substituted with cheaper oils to mimic the real thing, so you may not be getting what you’re paying for.

2Lemon Juice

Like other fruit juices, lemon juice can be sold as fresh or from concentrate (which can be diluted with water). But even lemon juice labeled as 100 percent pure has been found to contain citric acid. “It’s available as a chemical, and it’s very cheap,” notes Markus Lipp, Ph.D., senior director for Food Standards at the U.S. Pharmacopeial Convention. “The lemons are the most expensive ingredient, and sometimes only 10 to 30 percent is real juice, so manufacturers make three times as much money this way.”

The issue isn’t with whole bean coffee because it’s easier to recognize and know if the beans have proper form and color. “But with ground coffee, it can easily be adulterated and hard to tell what exactly is in that brown powder,” says Lipp. There have been reports of roasted chicory seeds, for example, being used as a filler. This is something that could cause allergies in unsuspecting java junkies.

According to the USP, tea has been found to contain lawn grass and other fern leaves. Not exactly what we’re hoping for when we curl up with a mug in the morning.


Tuna and other white fish, such as butterfish, have been caught in the “real” food lie. Tuna has been found to contain escolar—a cheaper, oily fish that is banned in Italy and Japan. Escolar has a high content of waxy esters that are likely to cause food poisoning called gempylotoxism or gempylid fish poisoning, according to the USP.
