Unhealthy: Pre-made pantry goods

Pre-made/processed pantry goods like canned ravioli, Hamburger Helper, or box goods that have pre-made, powdered sauces tend to have a lot of fat, sodium, and preservatives. Besides, with all the fresh food Costco offers at affordable prices, it can be easy and inexpensive to make your own! Not everything at Costco will save you money, however.

Healthy: Pre-made quinoa and brown rice

The trend has been pretty obvious thus far. If it is pre-made or too processed, you're probably going to want your cart to steer clear of that item—but Costco's quinoa and brown rice are an exception! Carla Schuit, MPH, RD, LDN, a licensed dietitian at Northwestern Medicine Central DuPage Hospital, always stocks up on these staples when she goes to Costco. "So easy to use as a base and toss some convenient protein in, such as grilled chicken, salmon, or shrimp," Schuit says. "Add a scoop of already made quinoa or brown rice and you have an easy complete meal. I always have two bags on hand."

Unhealthy: Giant cookies

If you've ever seen one of these monstrosities in person, you probably saw this coming. However, Dr. La Puma notes that the reason these delicious desserts are so bad for you isn't necessarily what's inside them; it's their size. You can still enjoy the chocolate chip goodness by cutting the cookie into quarters and savouring the flavour over the course of several days, he says.
