Rice Krispies Vs. Fruity Pebbles (Which is Best?)

Rice Krispies and Fruity Pebbles are both kinds of cereal aimed at kids and are very similar in structure, which is why Fruity Pebbles are now being used as a colorful alternative in a cereal treat bar.

If fat content is an important consideration for you, Rice Krispies come out top in this category because they don’t contain any fat or saturated fat.

Fruity Pebbles are also very low in fat with only 1.5g per 100g of cereal and they don’t contain any saturated fat.

Best for Fiber Content

Most breakfast cereals contain fiber especially if they’re made from whole grain or bran-based ingredients, but with Rice Krispies and Fruity Pebbles, neither contain any dietary fiber.

This is because they’re both rice-based, so it’s a bit like eating white rice, in that it’s bulk carbs but no fiber.

If you’re looking for a cereal with a high fiber content, check the ingredients for whole-grain wheat and especially bran which generally means they’re high-fiber.
