People comparing protein contributions
If you want cheese to add protein to a post-exercise meal, compare the amount in the portion you will eat, not just the figure per 100g. Check saturated fat and salt alongside it.
Who is choosing cheese after exercise?
People avoiding lactose
A lactose-free Cheddar may meet a lactose-avoidance requirement if you can consume milk protein. It is not a substitute for milk-free food when you have a milk allergy.
People planning portions and storage
If you are taking cheese to eat after exercise, consider how you will portion it and follow that pack’s storage instructions. Compare saturated fat per serving as well as per 100g.
What should you check on the pack?
Start with the nutrition values for your intended portion, then check milk tolerance, pack format and storage instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Compare protein per 100g and per serving. Sainsbury's lists 30.7g per 100g and 9.2g per 30g serving for Cathedral City High Protein Half Fat Mature Cheddar. | I want to know how much protein my actual portion contributes to a post-exercise snack or meal. |
| Saturated fat | Compare saturates per 100g and in your portion, even when a cheese is labelled reduced-fat. The NHS describes more than 5g saturates per 100g as high. | The saturated fat in my usual portion matters alongside its protein content. |
| Milk tolerance | Check for an explicit lactose-free claim and read the allergen declaration. Sainsbury's lists Arla Lactofree Mature Cheddar as containing less than 0.03% lactose, but its label declares milk. | I need to avoid lactose without confusing that requirement with a milk allergy. |
| Portions and storage | Check the serving format, refrigeration instructions and guidance for an opened pack. The Food Standards Agency distinguishes use-by dates, which concern safety, from best-before dates, which concern quality. | For a snack after exercise, I want a portion I can store and use as the particular pack directs. |
| Milk wording | Read the finished cheese’s nutrition, allergen and storage labels rather than treating ‘filtered’ or ‘longer-life’ milk wording as a nutrition value. | I want to choose for what the cheese contains and how I will use it. |
What can make the choice misleading?
-
Assuming protein-rich Cheddar is low in saturated fat
Marks & Spencer lists 25.4g protein and 21.7g saturates per 100g for its British Mature Cheddar. The NHS describes more than 5g saturates per 100g as high.
Compare protein, saturates and salt per 100g, then check how those values relate to the portion you intend to eat.
-
Treating lactose-free as milk-free
The Arla Lactofree Mature Cheddar label published by Sainsbury's declares milk and says the product is not suitable for people with a milk allergy.
If you need to avoid lactose, check the exact product’s claim. If you have a milk allergy, do not use lactose-free dairy cheese as a milk-free substitute.
-
Relying on cheese alone for a post-exercise meal
Cheese can contribute protein, but choosing it does not settle what else to include in a meal or snack after exercise.
Consider a measured portion with a carbohydrate-containing food, such as bread or potatoes, according to your wider eating and exercise needs.
-
Choosing by ‘filtered’ or ‘longer-life’ milk wording
Those words alone do not state the protein, saturated fat, allergens or storage requirements of the finished cheese.
Use the exact cheese pack’s nutrition panel and instructions to make those checks.
Which brands offer relevant examples?
Tesco
Tesco’s Cheddar range provides named reduced-fat formats to compare.
- Tesco Groceries lists 30% reduced-fat mature and extra-mature cheese, plus 50% reduced-fat grated mature cheese.
- A reduced-fat description does not tell you the saturated fat in your portion; check the chosen pack’s nutrition panel.
Sainsbury's
Sainsbury’s lists own-label mature and lighter cheese alongside a lactose-free Cheddar option.
- Its Cheddar category includes British Mature Cheddar, Lighter Mature Cheese and Arla Lactofree Mature Cheddar.
- Check the exact product label for the nutrition or allergen detail that matters to you.
M&S
M&S British Mature Cheddar offers a standard Cheddar label for portion comparisons.
- Marks & Spencer lists 25.4g protein per 100g.
- The same label lists 21.7g saturates and 1.80g salt per 100g; account for the portion you plan to use.
Waitrose
Waitrose lists reduced-fat and lactose-free Cheddar options as well as sliced mature Cheddar.
- Waitrose & Partners lists an Essential 30% Reduced Fat Extra Mature Cheddar and an Arla Lactofree Mature Cheddar.
- Its Essential Mature Sliced Cheddar has its own nutrition and opened-pack instructions; do not apply those details to other cheeses in the range.
Cathedral City
Cathedral City High Protein Half Fat Mature Cheddar is a labelled option for comparing protein per serving.
- Sainsbury's lists 30.7g protein per 100g and 9.2g per stated 30g serving for this product.
- The same listing gives 11.2g saturates per 100g, so the protein figure should not be considered on its own.
Joybuy cheese-based snack option
The Joybuy option here is a 60g cheese-based snack rather than a block of hard cheese. Check whether that format suits the snack or meal you have in mind.

Lava Cheese Plain Cheddar, 60g
This crunchy cheese-based snack may suit someone wanting a different format from a block of Cheddar after exercise. Check the pack’s protein and saturated fat values for the amount you will eat, and confirm its lactose status if you need to avoid lactose.
Questions about cheese after exercise
Is hard cheese enough on its own after exercise?
Cheese can contribute protein, but consider it as part of a snack or meal that also contains a carbohydrate food, such as bread or potatoes. The amount and combination you choose depend on your wider eating and exercise needs.
How can I compare saturated fat across hard cheeses?
Compare the saturates figures per 100g, then work out what they mean for the portion you intend to eat. The NHS describes more than 5g saturates per 100g as high; a reduced-fat description does not replace checking the nutrition panel.
Is lactose-free Cheddar suitable for a milk allergy?
No: the Arla Lactofree Mature Cheddar label published by Sainsbury's declares milk and says it is not suitable for people with a milk allergy. Avoiding lactose and avoiding milk are different requirements.
How should I store hard cheese after opening?
Follow the instructions on the specific pack, including its refrigeration and opened-pack guidance. For example, Waitrose & Partners says to keep its Essential Mature Sliced Cheddar below 5°C and consume it within 3 days of opening; other products may have different instructions.
What do best-before and use-by dates mean on cheese packs?
The Food Standards Agency says a use-by date relates to food safety, while a best-before date relates to food quality. Check which date appears on your particular pack and follow its storage instructions.
