Eggs are a great go-to food in general, but egg whites are truly where you'll find so many health benefits. And thankfully, Costco's version will last for a while.

"Egg whites are high in protein, low in fat, and contain no cholesterol," says Reda Elmardi, RD and owner of The Gym Goat. "They are a great source of calcium, iron, zinc, vitamin B12, riboflavin, niacin, thiamine, folate, and choline. Egg whites are also rich in lecithin, which helps maintain healthy skin and hair."

The thing with yogurt is that it's versatile. You can eat it as a quick breakfast, as a snack, or even use it as an ingredient in other dishes. Nonfat Greek yogurt is a great high-protein substitute for sour cream. Beth Wyman, MPH, RD, CDN, CDE, of Wyman Nutrition, likes the Dannon Oikos options because they're low in added sugar. Stock up at Costco, where a box of 18 is under $14.

Similarly, your salad greens can do more than just serve as a salad base—especially the options sold in bulk at Costco.

"I make a green smoothie every day," says Sharon Palmer, MSFS, RDN, The Plant-Powered Dietitian. "Green leafy vegetables have plentiful nutrition benefits, including vitamins, minerals, fiber, and phytochemicals that fight disease."

Keeping these avocado cups on hand in your fridge will save you when you're feeling snacky and don't want to eat something sweet or unhealthy. They're also great for work lunches when you're in a pinch. They have the good fats you expect from avocados but are already ready to go.

"Not only are these single-serve packs super convenient for lunchbox-packing, but they also far outlast fresh avocados who're notorious for being not ripe enough or already rotten when you need them," says Jenny Champion, MS, RD, CPT.

Don't be afraid to eat butter, even if you're on a healthy eating plan. It has plenty of good-for-you qualities!

"You may not think of butter as a health food, but if you're buying a high-quality brand, it most certainly is," Champion says. "Grass-fed butter is chock-full o' vitamins, antioxidants, and omega 3 fats, which are great for lowering inflammation and improving overall health."

Costco's versions come in 2-pound boxes for around $15.

Grillo's Pickles

Keeping healthy snacks handy in your fridge can curb cravings and encourage you to make good choices when you're peckish between meals. Pickles are pretty much always a great option for this, and Costco members love this brand.

"Pickles are a flavorful, low-calorie snack with just 5 calories per serving," says Mia Syn, MS, RDN. "Grillo's Pickles are refrigerated instead of jarred and made with just a handful of simple, fresh ingredients: cucumber, brine and seasonings. Plus, they can help you meet your recommended 2-3.5 cup servings of vegetables for the day."
