As a dietitian following the Mediterranean diet, I’ve prioritized increasing my daily fiber intake. Costco is one of my go-to spots to stock up on fiber-rich staples in bulk. Here are some of my favorite finds that help me hit my fiber goals without sacrificing flavor or convenience.
One key strategy is incorporating frozen riced cauliflower into grain dishes and smoothies. This low-carb, high-fiber alternative to rice provides a versatile and nutritious boost. I also love using Good Foods organic avocado mash as a condiment on sandwiches for added creaminess and heart-healthy fats. With 4 grams of dietary fiber per serving, it’s a great way to increase my daily intake.
SunGold kiwis are another favorite snack, packed with about 2 grams of fiber each. I enjoy them on Greek yogurt or eating them whole as a quick fiber fix. Dried plums like Kirkland Signature Sunsweet prunes are also high in fiber and versatile, making them perfect for snacking or adding to smoothies.
Frozen fruit blends are another convenient option, with Kirkland Signature triple-berry blend being one of my favorites. This antioxidant-loaded mix is a dietitian’s dream, providing a naturally sweet fiber boost without the need for fresh fruit. Actual Veggies black-bean veggie burgers are also a staple, containing 6 grams of fiber per patty.
For breakfast, I enjoy Catalina Crunch protein cereal, which boasts an impressive 9 grams of fiber per serving. I sprinkle chia seeds on yogurt, smoothies, and oatmeal for an extra fiber kick, with about 10 grams of fiber per serving. Organic mushrooms add volume and a touch of fiber to many dinner recipes, making them a great addition to beef dishes.
Finally, Kodiak Power Cakes flapjack and waffle mix provides a convenient way to boost protein and fiber into breakfasts. With 15 grams of protein and 5 grams of fiber per serving, it’s an impressive option for families or busy mornings.
