How To Shop for Healthy Foods at Costco

With Costco’s bulk value, it's tempting to stock up on items you don’t need, but the smarter approach is to focus on whole foods first. The healthiest foods to buy at Costco are easy to spot once you know what to look for, so start with produce and frozen vegetables. Then add lean proteins, whole grains and dairy alternatives.

Pantry staples like quinoa, canned beans, nut butters, brown rice and olive oil are cost-effective essentials. For snacks, try protein bars, mixed nuts and hummus with veggies. Before long, you’ll forget about pastries and chips. With meal planning, label reading and an eye for nutrient-dense choices, shopping for the healthiest food at Costco can support long-term health while keeping weekly grocery costs in check.

What Is the Healthiest Food at Costco Food Court?

If you’re wondering how to start eating healthy, you should first avoid excessively browsing the Costco food court menu for pizza, hot dogs and sugary frozen drinks. Instead, opt for the healthiest option available — the rotisserie chicken Caesar salad — and go easy on the dressing.

While an occasional treat isn’t a problem, moderation is important to avoid overconsuming empty calories. You can also split your portions and save some for later, swap soda for water with your meal and skip extra toppings.

Finding the healthiest food at Costco is easier than it seems. Pay attention, plan and prioritize whole, nutrient-dense foods. With the right approach, every Costco trip can feel effortless, whether you’re stocking up on pantry staples or frozen favorites.
