For an older adult who is eating poorly but can safely drink ordinary fluids, a fortified milkshake can add to meals; Torbay and South Devon NHS Foundation Trust advises serving nourishing drinks between meals, not using them as meal replacements. A large ready-to-drink carton offers convenience, but its protein, energy, sugars, allergens and storage instructions need checking against the person’s needs. Ongoing weight loss, swallowing difficulties or a prescribed diet call for individual clinical advice rather than a choice based on milkshake packaging.
Who is this choice for?
Older adults eating less than usual
When someone can safely drink ordinary fluids but has a poor appetite, a nourishing drink may be considered alongside food. NHS Lanarkshire describes fortified milkshakes in smaller drinks between meals; continuing poor intake or unintended weight loss warrants assessment.
People planning several servings from one carton
A 1-litre carton can be divided into servings, provided its nutrition label suits the person and it can be stored as directed. The Tesco listings for the Pro Mlk, Arla Protein and Yazoo 1-litre drinks specify refrigeration after opening and use within three days.
People with dietary or swallowing restrictions
Milk allergy, diabetes, kidney disease, swallowing difficulties or a prescribed nutrition plan can change which drinks and textures are appropriate. Follow the individual care plan rather than choosing from protein or sugar claims on the front of a pack.
What matters when choosing?
Fortified homemade drink
Consider when: an older adult is eating poorly, can safely drink ordinary fluids and has help preparing a drink suited to their needs.
Keep in mind: preparation and individual portions matter; Torbay and South Devon NHS Foundation Trust says nourishing drinks belong between meals, not in place of them.
Ready-to-drink carton
Consider when: convenience matters and the labelled nutrition, allergens and serving size fit the person’s needs.
Keep in mind: a protein figure alone does not establish that a drink provides enough energy or complete nutrition; a large opened carton also needs suitable storage.
| Priority | What to check | Your needs |
| Role alongside meals |
Decide whether the drink is an addition to food. For a homemade fortified drink, check the ingredients, portion size and whether ordinary fluids are safe to swallow. |
With a small appetite, I may manage a drink between meals without letting it replace food. Torbay and South Devon NHS Foundation Trust advises against using nourishing drinks as meal replacements. |
| Protein |
Compare grams per 100 ml for the same type of drink, then consider the portion likely to be consumed. Tesco lists 7.8 g for Pro Mlk Chocolate 1L, 5.7 g for Arla Protein Chocolate 1L and 3.2 g for Yazoo Chocolate 1L. |
If protein contribution matters to me, I want to compare the labelled amount in a serving I would actually drink, not just a front-of-pack phrase. |
| Energy and sugars |
Read kcal and sugars per 100 ml as separate figures. Tesco lists 62 kcal for Pro Mlk, 51 kcal for Arla Protein and 62 kcal and 8.6 g sugars for Yazoo, each per 100 ml of the named chocolate drink. |
Where eating enough is the concern, protein alone does not answer my energy question. If blood glucose management is involved, I need advice suited to the individual rather than assuming a particular sugar claim settles the choice. |
| Allergens and texture |
Read the current ingredients list for allergens, and follow any prescribed swallowing plan. The named drinks contain milk; the Tesco-listed Mars 400 ml drink also contains barley. |
I cannot choose by flavour or nutrition figures alone if the person has a milk allergy or needs a specified fluid texture. |
| Serving and storage |
Compare individual portions with a shared carton and follow the pack’s storage instructions. The three Tesco-listed 1-litre cartons specify refrigeration after opening and use within three days. |
A large carton suits me only if its contents can be served and stored as directed after opening. |
What should you avoid overlooking?
-
Using a flavoured milkshake in place of meals
Torbay and South Devon NHS Foundation Trust says nourishing drinks do not meet complete nutritional needs on their own. This matters particularly when someone is already eating poorly or losing weight.
Offer a suitable drink between meals and seek assessment if poor intake or unintended weight loss continues.
-
Choosing by a protein or sugar claim alone
Protein, energy and sugars answer different questions. A no-added-sugar label also does not mean that a drink contains no sugars: Tesco lists 6.5 g sugars per 100 ml for its Mars no-added-sugar milk drink.
Compare the per-100-ml panel and ingredients with the person’s intended serving and dietary advice.
-
Overlooking allergens or swallowing instructions
The Tesco-listed drinks discussed here contain milk, while its Mars drink also lists barley. A drink’s ordinary consistency may not match an individual swallowing plan.
Check the current pack and follow the person’s allergy and swallowing guidance before serving it.
-
Opening more than can be used as directed
The Tesco listings for Pro Mlk, Arla Protein and Yazoo 1-litre drinks specify refrigeration after opening and use within three days.
Choose a pack size that fits likely intake, refrigerate an opened carton as directed and follow its on-pack date and storage instructions.
Relevant drink brands
These brand examples illustrate different pack sizes and label questions; brand inclusion does not establish that a drink is suitable for an individual nutrition plan.
Pro Mlk
The Tesco-listed Chocolate 1L is a chilled protein shake to compare when protein per 100 ml is a priority.
- Tesco lists 7.8 g protein and 62 kcal per 100 ml.
- It needs chilled storage; the listing says to use it within three days after opening. Its protein figure does not make it a meal replacement.
Arla Protein
The Tesco-listed Chocolate Milk Shake 1L offers another labelled protein figure for a large carton.
- Tesco lists 5.7 g protein and 51 kcal per 100 ml.
- The listing explicitly says it is unsuitable for people with a milk allergy. Refrigerate after opening and follow the three-day consumption instruction.
Yazoo
The Tesco-listed Chocolate Milkshake 1L is a standard flavoured milk drink in a large carton.
- Tesco lists 3.2 g protein and 62 kcal per 100 ml.
- Its label lists 8.6 g sugars per 100 ml and instructs refrigeration after opening and use within three days.
Mars
The Tesco-listed no-added-sugar chocolate milk drink comes in a 400 ml pack rather than a 1-litre carton.
- Tesco lists 3.5 g protein and 63 kcal per 100 ml for this drink.
- The listing records 6.5 g sugars per 100 ml, sweeteners, milk and barley; the smaller pack serves a different portion-planning need.
FRijj
Tesco lists a 471 ml Chocolate Milkshake, a smaller single pack than the 1-litre cartons above.
- The 471 ml size may be relevant when planning portions without opening a larger shared carton.
- Check the current pack’s ingredients and nutrition panel before deciding whether it fits the person’s needs.

Common questions
Can a supermarket milkshake replace meals if an older adult is eating poorly?
No. Torbay and South Devon NHS Foundation Trust advises giving nourishing drinks between meals because they do not meet complete nutritional needs on their own. Persistent poor intake or unintended weight loss calls for assessment rather than reliance on a retail drink.
How do the named 1-litre drinks compare for protein?
Tesco lists 7.8 g protein per 100 ml for Pro Mlk Chocolate 1L, 5.7 g for Arla Protein Chocolate 1L and 3.2 g for Yazoo Chocolate 1L. This compares their labelled protein content, not their overall suitability for an individual older adult.
Does a high-protein carton answer a need for more energy?
Not by itself: check the energy figure separately. Tesco lists 51 kcal per 100 ml for Arla Protein Chocolate 1L and 62 kcal per 100 ml for Pro Mlk Chocolate 1L. Someone losing weight or eating poorly needs their overall intake and nutrition plan assessed.
What if the person has diabetes or advanced kidney disease?
Seek advice for the person’s condition rather than assuming a retail shake or no-added-sugar claim is appropriate. The Buckinghamshire, Oxfordshire and Berkshire West Integrated Care System formulary advises avoiding milkshake-style powdered oral nutritional supplements in uncontrolled diabetes because of sugar content and notes a separate restriction on powdered supplements in chronic kidney disease stages 4 or 5; those cautions should not be applied indiscriminately to every retail drink.
What if the person needs thickened fluids?
Follow their individual swallowing plan before serving or altering a milkshake. Norfolk and Waveney Integrated Care System’s care-home guidance treats swallowing difficulties and IDDSI fluid levels as specific nutrition and hydration considerations; an ordinary drink’s texture should not be assumed suitable.
