Shoppers wanting a portioned sweet treat
A 28 g marshmallow-flavoured cereal bar or a 20 g plain marshmallow confection gives you a defined portion to consider. Check whether you are buying one item or a multipack.
Who is this for?
Shoppers comparing protein content
If protein is the reason for your post-gym snack, compare the amount per bar. Kellogg's lists 0.8 g protein in a 28 g Rice Krispies Squares Marshmallow bar; a product labelled as a protein bar is a different type of choice, whose own serving information still needs checking.
Shoppers checking ingredients
The Rice Krispies Squares Marshmallow bar contains barley, wheat, milk and beef gelatine, and may contain soya, according to Kellogg's. Check the current pack if any of these ingredients affect your choice.
What should you check?
Start with why you want the snack, then compare the portion, nutrition and ingredients of the exact product you plan to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Snack purpose | Compare carbohydrate and protein per serving, not just the product name. Kellogg's lists 21 g carbohydrate and 0.8 g protein per 28 g Rice Krispies Squares Marshmallow bar. | I want a sweet snack after training, or I want a snack with a stated amount of protein. Those are different reasons to choose a bar. |
| Portion and pack | Check the weight of each item and how many are in the pack. Sainsbury's lists the Kellogg's marshmallow bar as four 28 g bars per pack; Tesco lists Barratt Flumps as a 20 g item. | For my gym bag, I want to know the size of one portion and whether I am buying a single confection or several bars. |
| Sugars and ingredients | Read sugars on the same per-bar or per-100 g basis when comparing labels. Kellogg's lists 9 g sugars per 28 g bar; also check its barley, wheat, milk, possible soya and beef gelatine declarations. | I may be choosing by ingredients as well as flavour, so the current label matters more than a general assumption about marshmallows. |
Common buying mistakes
-
Assuming every snack bar has substantial protein
Kellogg's Rice Krispies Squares Marshmallow has 0.8 g protein per 28 g bar, according to Kellogg's. Its bar shape does not make it equivalent to a protein-focused snack.
If protein content is important to your choice, compare the declared amount per serving on the alternatives you are considering.
-
Assuming marshmallows have the same ingredients
Kellogg's lists beef gelatine in its marshmallow bar, alongside barley, wheat and milk; the bar may contain soya. M&S also lists beef gelatine in its Soft Marshmallows.
Read the ingredient and allergen information on the exact current pack, particularly if you avoid animal gelatine or any listed allergens.
-
Confusing one bar with a single-bar purchase
Sainsbury's lists four 28 g Kellogg's marshmallow bars in one pack, while Tesco lists Barratt Flumps as a 20 g individual confection.
Check both the number of items and their individual weight if you only want one portion to take with you.

Questions about choosing a snack
Does a marshmallow cereal bar provide much protein?
Kellogg's lists 0.8 g protein per 28 g Rice Krispies Squares Marshmallow bar, alongside 21 g carbohydrate. If protein content is your reason for choosing a post-gym snack, compare that per-bar figure with the declared serving information on other products or on food you plan to eat with it.
What should I check on a marshmallow bar label?
Check the portion size, sugars, protein, ingredients and allergen declaration on the exact pack. Kellogg's lists barley, wheat, milk and beef gelatine for Rice Krispies Squares Marshmallow and says it may contain soya; do not assume a different marshmallow product has the same ingredients.
