Whether you’re choosing a snack before a busy afternoon, packing something for a walk or looking for a bar to enjoy between meals, you may have wondered how much protein a snack should contain.
How much you need depends on your overall diet, individual needs and lifestyle. The bigger picture is a balanced and varied diet that provides enough protein alongside other key nutrients (NHS).
Here’s what to know about protein and how it can fit into your everyday snack choices.
How much protein do adults need each day?
In the UK, adults are generally recommended to consume around 0.75g of protein per kilogram of body weight per day. Based on historic average body weights, this is approximately 45g per day for the average woman and 55g per day for the average man (UK Government dietary recommendations).
These figures are broad reference values rather than personal targets. Your own protein needs may be different, so it is more useful to consider your overall eating pattern than to judge a single snack in isolation (BHF).
Do protein needs vary from person to person?
Yes. Protein requirements can change over time and may be influenced by:
- Body weight
- Age and life stage
- Activity levels and sporting goals
- Pregnancy and breastfeeding
- Recovery from illness or surgery
- Overall health status
Some groups may need more protein or may benefit from paying closer attention to protein quality and distribution. This includes some older adults, athletes and people with particular health needs. During pregnancy and lactation, recognised recommendations also include additional protein, with the amount varying by trimester and stage of breastfeeding (EFSA).
If you have a health condition, are recovering from illness or surgery, or are unsure about your individual needs, a qualified healthcare professional can provide personalised advice.
Is more protein always better?
Protein is an important nutrient, but eating more is not automatically better.
There is no official maximum protein limit for everyone. Some research has examined intakes of up to around 2.2g per kilogram of body weight per day, but this should not be treated as a target for the general population. Regularly consuming very high amounts may be unsuitable for some people as it could put a strain on the kidneys, particularly those with existing kidney problems (BHF) (protein distribution research).
The aim should be to consume an amount that suits your lifestyle and health profile, while also making room for other important nutrients.
Four quick tips for thinking about protein in snacks
- Look at your whole diet: Protein needs are about your overall intake, not one snack in isolation.
- Consider your individual needs: Age, body weight, activity levels, life stage and health can all make a difference.
- Read the label: Compare the protein per bar and per 100g if you’re comparing products.
- Keep variety in mind: Protein is one part of a balanced diet alongside fibre, whole grains, fruit, vegetables, nuts and other key nutrients.
Should you spread protein throughout the day?
Research suggests that spreading protein intake throughout the day may help your body use it effectively. However, there is no single amount that everyone needs at breakfast, lunch, dinner or snack time (ISSN position stand).
For most healthy adults, protein intake does not need to be rigid. Eating a variety of foods across the day and aiming to meet your overall needs is usually more useful than trying to reach a precise amount in every eating occasion. (ISSN position stand)
