Who is this for?

Students comparing flavoured milk drinks

If a drink is part of a revision break, compare fat, saturates and sugars per 100ml, then consider how much of the bottle you will drink.

Parents buying revision snacks

A milkshake can be considered as a drink or snack, not a replacement for regular meals. Norfolk and Norwich University Hospitals NHS Foundation Trust advises that teenagers need regular meals and snacks and that grazing instead of meals can lead to an unbalanced diet.

Shoppers checking added sugar

If you are considering a no-added-sugar formulation, check total sugars and the ingredients list too. The Frijj Reduced Sugar and Mars No Added Sugar drinks listed by Tesco contain naturally occurring sugars and sweeteners.

What should you compare?

Start with the per-100ml figures to compare drinks, then use the bottle size and serving information to judge the amount you might actually consume.

Priority What to check Your needs
Fat and saturates Compare both figures per 100ml on like-for-like drinks. Tesco Groceries lists 1.4g fat and 0.9g saturates for Yazoo Chocolate, 1.9g and 1.2g for Frijj Reduced Sugar, and 2.2g and 1.4g for Mars No Added Sugar. I want to compare fat without treating the lowest figure as a judgement about the whole drink.
Sugars and sweeteners Check total sugars per 100ml separately from any no-added-sugar claim, then read the ingredients. Tesco Groceries lists 8.6g sugars for Yazoo, 4.7g for Frijj and 6.5g for Mars per 100ml; the Frijj and Mars products contain sweeteners. If I choose a no-added-sugar drink, I still want to know its total sugars and whether it contains sweeteners.
Bottle size Check the pack volume and stated serving size. Tesco Groceries lists all three named-brand drinks in 400ml bottles; the Yazoo and Mars labels describe two 200ml portions per bottle. A serving figure matters less to my choice if I expect to drink the entire bottle during one break.
Ingredients and routine Check the current bottle for allergens and storage directions. The Tesco listings declare milk in all three drinks and barley in Mars. Keep drinks and snacks alongside regular meals rather than using them to replace meals, in line with Norfolk and Norwich University Hospitals NHS Foundation Trust’s teenage-eating guidance. I need a drink whose ingredients suit me and a way to store any portion I leave for later.

Common buying mistakes

  • Checking fat but not the rest of the label

    A lower fat figure does not tell you the drink’s sugars, saturates or the amount you will consume from a full bottle.

    Compare drinks per 100ml, then check those other figures against the portion you plan to drink.

  • Reading “no added sugar” as “sugar-free”

    The Frijj Reduced Sugar and Mars No Added Sugar products listed by Tesco Groceries contain naturally occurring sugars and sweeteners.

    Read the total-sugars figure and ingredients list before deciding whether either formulation suits you.

  • Using a milkshake instead of a meal

    Norfolk and Norwich University Hospitals NHS Foundation Trust advises that snacking throughout the day in place of meals can result in an unbalanced diet.

    Treat a revision drink as a drink or snack alongside regular meals, not as a complete meal replacement.

  • Skipping the current label

    Ingredients and storage instructions matter when you need to avoid an allergen or plan to keep an opened bottle. The named-brand drinks contain milk, and the Mars drink also lists barley.

    Check the exact bottle’s allergen statement and directions before buying or saving some for later.

Questions about revision snacks

Does the lowest-fat milkshake automatically make the right revision snack?

No. Compare fat and saturates per 100ml, then check sugars, ingredients and how much you will drink. Norfolk and Norwich University Hospitals NHS Foundation Trust advises regular meals and snacks for teenagers rather than snacking in place of meals.

Should I compare figures per 100ml or per serving?

Use per 100ml for a like-for-like comparison, then check the serving and bottle size for the amount you plan to drink. Tesco Groceries lists two 200ml servings on the 400ml Yazoo Chocolate and Mars No Added Sugar bottles.

Does “no added sugar” mean these drinks contain no sugar?

No. The Frijj Reduced Sugar and Mars No Added Sugar drinks listed by Tesco Groceries contain naturally occurring sugars and sweeteners. Their total-sugars figures and ingredients lists provide the information needed to compare them.

What if I need to avoid milk or barley?

The specified Yazoo, Frijj and Mars drinks all declare milk, and the Mars drink also declares barley, according to their Tesco Groceries listings. Check the current label of the exact product before buying if either ingredient must be avoided.

Can I keep half a bottle for another revision break?

Follow the storage directions on the exact bottle and refrigerate it if those directions require it. The Tesco listings say to refrigerate Yazoo and Mars after opening and consume them within three days; Frijj’s listing says to keep it refrigerated and use it within three days of opening and by its use-by date.
