Who is this choice for?

People choosing a lower-fat late-night drink

If you drink milk or add it to cereal at night, compare semi-skimmed with 1% and skimmed milk according to how much you want to reduce fat.

Occasional milk users

If a carton may sit unused between snacks, its size, date mark and instructions for storage after opening matter alongside the type of milk.

People choosing lactose-free dairy milk

If you are avoiding lactose, check the lactose statement on the particular product. Lactose-free cow's milk still contains milk and is not an alternative for a milk allergy.

What should you check before buying?

Choose the fat level first, then check whether the pack size and storage instructions suit how often you will use the milk.

Priority What to check Your needs
Fat level Compare fat and saturates on the same per-100ml or per-100g basis. For older children and adults cutting down on fat, the NHS points to 1% or skimmed milk; semi-skimmed is another lower-fat choice than whole milk. I want milk with less fat than whole milk, but I can choose between semi-skimmed and a further reduction with 1% or skimmed.
Storage and pack size Check the date mark, unopened storage conditions and time allowed after opening. Arla states up to three weeks unopened and seven days opened at 0°C to 5°C for its Cravendale filtered semi-skimmed 2L milk; follow the instructions on the pack you buy. Milk is an occasional late-night snack for me, so I need a size and opened-life I can use within the stated time.
Lactose and allergens Check the exact product's lactose and allergen statements. Arla Lactofree semi-skimmed milk drink is labelled less than 0.03% lactose, but its product information says it is unsuitable for people with a milk allergy. If I need to avoid lactose, I want to distinguish that from a milk allergy before choosing a dairy product.

What is easy to overlook?

  • Assuming whole milk is a lower-fat option

    Whole milk does not fit a purchase aimed at reducing milk fat. The NHS points older children and adults who want to cut down on fat towards lower-fat milk, including 1% or skimmed.

    Choose the milk type before comparing the fat and saturates values on the packs under consideration.

  • Overlooking how soon an opened carton must be used

    Storage instructions differ by product. Arla Cravendale and Sainsbury's filtered semi-skimmed 2L products each state seven days after opening; a Joybuy Morrisons long-life semi-skimmed listing states three days after opening.

    Choose a carton size you expect to use within its own stated opened-life, and follow its refrigeration instructions.

  • Confusing lactose-free with milk-free

    Removing most lactose does not remove the milk allergen. The Arla Lactofree semi-skimmed product explicitly says it is unsuitable for people with a milk allergy.

    If you have a milk allergy, do not substitute lactose-free cow's milk for a milk-free product; check the pack's allergen information.

Milk for a midnight snack: questions answered

Is whole milk a lower-fat choice?

No. If reducing milk fat is the aim, compare semi-skimmed, 1% and skimmed options instead. The NHS specifically points older children and adults wanting to cut down on fat towards 1% or skimmed milk.

When might I choose semi-skimmed rather than skimmed?

Semi-skimmed is a middle option when you want less fat than whole milk without choosing skimmed. Check the exact pack: Sainsbury's filtered semi-skimmed milk lists 1.8g fat and 1.1g saturates per 100ml, but those values should not be assumed for every product.

Does filtered milk last longer after opening?

Check the particular bottle rather than relying on the word 'filtered'. Arla Cravendale and Sainsbury's filtered semi-skimmed 2L products each state seven days after opening, subject to their refrigeration instructions.

Is lactose-free semi-skimmed milk suitable for a milk allergy?

No. The Arla Lactofree semi-skimmed product states that it is not suitable for people with a milk allergy, despite its less than 0.03% lactose claim. Check the allergen statement on the pack.

How should I store milk kept for occasional late-night use?

Follow the date mark and storage instructions on the carton you buy. Arla specifies 0°C to 5°C for its Cravendale filtered semi-skimmed milk; a Joybuy Morrisons long-life semi-skimmed listing says to refrigerate after opening and use within three days.
