Avocados, we are told, are great for our health. They’re high in healthy fats, nutrients, potassium and folate; they can lower our cholesterol and triglyceride levels; and if we’re going to snack, they’re a great option. They’re low in sugar, high in fiber, and might even help us ward off disease and infection, according to WebMD.

But not all avocados — or guacamole, in this case — are equal. Check the label on that store-bought guac. Many varieties are filled with artificial colors, cheap oils, and empty calories. And that restaurant topping may not be any better. Watch the video below.

“I wouldn’t be surprised if store-bought guacamole used filler ingredients to keep the price lower,” said Stella Metsovas, a California-based clinical nutritionist.

“I try to be optimistic with products that might be less than optimal with their ingredient structure. For example, truffle salt was one of the hottest spices at the Fancy Food Show in San Francisco a couple of weeks ago,” she told LifeZette. “Does the spice compare to the real truffle that grows in the ground? This is a drastic comparison, of course, but consumers crave certain tastes and manufacturers seek to fulfill that.”

A Florida man launched a proposed class action lawsuit in January. It accused “guacamole maker Yucatan Foods LP of deceiving consumers by indicating on the product’s label that it was ‘all natural’ and made only from avocados and spices, when in fact it contained additives as well,” according to Law360.com.

The California-based manufacturer claims that at least three varieties of its guacamole contain 95 percent avocado and 5 percent spices, and at least nine varieties are described on the label as “all natural.” The lawsuit states all of the guacamole products instead contain additional synthetic ingredients such as “evaporated cane juice” and citric acid.

Best advice: Make your guac at home with avocados you buy yourself — for the big game this weekend or any time.
