Rice Krispies Vs. Fruity Pebbles Nutritional Comparison
We’ll now take a look at the nutritional comparison, and because each cereal has a different recommended serving size, I’ll be comparing them per 100g of cereal to keep the comparison accurate. I’ll also include the per serving data for information.
To clarify, the products I’m comparing are Kellogg’s Rice Krispies and Post Original Fruity Pebbles (other varieties are available).

|Post Fruity Pebbles||389kcal||140kcal (per 36g serving)|
Best for Carbohydrate Content
I’ve included carbohydrates for information but not in the overall comparison because neither cereal can be considered a low-carb breakfast option.
So for information, the cereal that is lowest in carbs is Fruity Pebbles, which contains just 4g fewer carbs per 100g compared to Rice Krispies; however, Fruity Pebbles are higher in sugar, which I’ll cover in the next section.
|Cereal Type||Carbohydrates Per 100g||Carbohydrates Per Serving|

The biggest difference between Rice Krispies and Fruity Pebbles is the sugar content, with Fruity Pebbles containing over three times the amount of sugar of Rice Krispies.
To explain this in terms of a daily recommended value, a serving of Rice Krispies contains 8% of the daily value compared to Fruity Pebbles which contain 25%.
|Cereal Type||Sugars Per 100g||Sugars Per Serving|
|Kellogg’s Rice Krispies||10g||4g (per 40g serving)|
|Post Fruity Pebbles||33g||12g (per 36g serving)|

Protein content is becoming increasingly important to consumers when choosing a certain food and although neither kind of cereal is particularly high in protein, Rice Krispies contain 2g more protein than Fruity Pebbles.

|Kellogg’s Rice Krispies||7.5g||3g (per 40g serving)|

Best for Fat Content
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.
I can also confirm that neither Rice Krispies nor Fruity Pebbles contain any cholesterol.
|Cereal Type||Fat Per Serving||Saturated Fat per Serving|
|Kellogg’s Rice Krispies||0g||0g (per 40g serving)|
|Post Fruity Pebbles||1.5g||0g (per 36g serving)|
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.
|Cereal Type||Dietary Fibre Per 100g||Dietary Fibre per Serving|
|Kellogg’s Rice Krispies||0g||0g (per 40g serving)|
|Post Fruity Pebbles||0g||0g (per 36g serving)|

Best for Vitamins/Minerals
Rice Krispies and Fruity Pebbles are fortified breakfast cereals which means they have added vitamins and minerals to help consumers to get closer to their daily values of certain nutrients.
Although Rice Krispies are higher in vitamin D, iron, and vitamin B6, Fruity Pebbles are higher in vitamins and minerals in more categories.
