Who is this for?

Students taking a drink to lunch

A bottle is easy to carry between lectures, but check its size against the NHS guidance of a combined maximum of 150ml of juice and smoothies a day for 5 A Day. Follow the pack’s storage instructions while you are out.

Students comparing sugar labels

If “no added sugar” catches your eye, read the sugars declaration too. Fruit smoothies can still contain naturally occurring sugars.

Students considering added ingredients

If you are looking for protein, fibre or vegetables in a lunch drink, compare the declared amount and serving size rather than choosing on the front-of-pack wording alone.

What should you check?

Start with when you will drink the smoothie and how much is in the bottle, then compare the blend and its nutrition declaration.

PriorityWhat to checkYour needs
Portion and timing Check the bottle volume and serving size. The NHS advises a combined maximum of 150ml of juice and smoothies a day for 5 A Day and recommends drinking them with meals. I want a drink with lunch, without counting a larger bottle as extra 5 A Day portions.
Sugar wording Compare sugars on the same stated basis, such as per 100ml, and check the ingredients. “No added sugar” does not mean the drink contains no naturally occurring sugars. A no-added-sugar label would not answer my question about how much sugar is in the drink.
Type of blend Read the ingredients if vegetable content matters. Waitrose & Partners lists 25% vegetables for the examined Innocent Fruit + Veg 250ml smoothie; that does not change the NHS portion guidance for smoothies. I may prefer a fruit-and-veg blend, but I still want to know what is in this particular bottle.
Added protein or fibre Check the amount per stated serving, the serving volume and the sugars declaration. Tesco Groceries lists 10g protein per serving for Naked Protein Machine and 4.2g fibre per serving for Naked Fibre Machine. Added protein or fibre matters to me only if the declared serving fits what I am choosing for lunch.
Storage and labels Follow the bottle’s storage and use-by instructions. Check the physical pack for current ingredients, allergens and nutrition information. I need to know whether I can carry the drink through lectures before lunch.

Common buying mistakes

  • Treating “no added sugar” as “zero sugar”

    The wording concerns added sugar, not all sugar in the drink. Tesco Groceries lists 10g sugars per 100ml for the examined Innocent Strawberries & Bananas smoothie.

    Read the ingredients and compare the sugars declaration on the same measurement basis.

  • Counting the whole bottle as several 5 A Day portions

    A 250ml bottle exceeds the NHS’s combined 150ml daily amount for juice and smoothies that counts towards 5 A Day; drinking more does not add another portion.

    Have the smoothie with lunch if you choose one, and consider other fruit and vegetables separately.

  • Comparing functional claims without their serving sizes

    Tesco Groceries lists Naked Protein Machine’s 10g protein claim per serving, with nutrition given for 300ml, while the bottle contains 750ml. A per-serving claim is not a description of the whole bottle or lunch.

    Compare the declared serving volumes and nutrition values before deciding whether an added ingredient is relevant.

  • Overlooking storage and the current label

    A smoothie that requires refrigeration needs appropriate storage until lunch. Ingredients and allergen information can also change between product listings and the pack you buy.

    Follow the pack’s storage instructions and check its current ingredients, allergens and use-by date.

Questions about lecture-day smoothies

Does a 250ml smoothie count as more than one of my 5 A Day?

No. The NHS says a combined maximum of 150ml of juice and smoothies a day counts as one 5 A Day portion, even if the bottle contains more.

Should I have a smoothie during a lecture break or with lunch?

Have it with lunch where possible. The NHS recommends drinking juices and smoothies at mealtimes because crushing fruit releases sugars that can damage teeth.

Is a “no added sugar” smoothie sugar-free?

No. Fruit sugars can still be present. Tesco Groceries lists 10g sugars per 100ml for the examined Innocent Strawberries & Bananas smoothie, despite its no-added-sugar wording.

Should I choose an added-protein smoothie for lunch?

Choose it if the declared protein amount is relevant to what you want from your lunch, not simply because the claim appears on the bottle. Tesco Groceries lists 10g protein per serving for Naked Protein Machine; check its 300ml nutrition basis against its 750ml bottle size and the rest of your meal.

What should I check before carrying a smoothie to lectures?

Read the physical pack’s storage instructions, use-by date, ingredients, allergens and nutrition declaration. If it requires refrigeration, plan how you will keep it chilled until lunch.
