5. Kirkland Signature Three Berry Blend

Did you know that berries are among the healthiest foods on the planet? And for good reasons actually… They taste amazing while giving you an impressive amount of health benefits. Berries can protect your cells from free radical damage due to their powerful antioxidants, they can improve your blood sugar levels, they can keep your weight in check and they can also protect against cancer.

Yes, one tiny little fruit can do all that! The best thing about berries? Studies found that frozen berries are healthier than fresh ones. How so? Most frozen berries are frozen the same day that they are harvested, so they preserve their benefits better than their fresh versions. Zarabi says she loves this Costco product because “it’s convenient and full of vitamins, fibers, and antioxidants.”
