For a night-shift snack, choose by the protein stated per individual bar, then check the pack size, ingredients and allergens against what you can eat. Tesco lists 10g protein in a 40g Nature Valley Protein Peanut & Chocolate bar; vegan alternatives include the TREK Original Oat flapjack and nākd. Cocoa Hazelnut, although the TREK retailer page gives conflicting protein figures that need checking on the pack.
If you have little time to prepare food or limited choices during a night shift, a bar you can pack beforehand gives you a planned snack for your break. A Greater London Authority study describes food-preparation and access difficulties among hospital night workers in London.
If protein quantity matters to your choice, compare the amount for one bar as well as its weight. Product names alone do not tell you how the portions compare.
If you need a vegan, gluten-free or dairy-free bar, check the claim on the exact product. Read its ingredient and allergen information separately: the examples here include bars with peanuts, other nuts, soya or milk.
Start with a bar you can pack for your break, then compare its labelled portion and protein amount. Dietary claims and allergens need their own check; neither follows from the word “protein” in a product name.
| Priority | What to check | Your needs |
|---|---|---|
| Food during the shift | Check the pack format and whether you can carry and store a bar as its label directs. Plan when you would eat it during a break. | I want a snack ready to put in my bag when preparing food before work is difficult. The Greater London Authority’s study of London hospital night workers describes how missed preparation can leave workers relying on food available during a shift. |
| Protein quantity | Compare protein per bar alongside bar weight; use per 100g figures if you want a same-weight comparison. Tesco lists 10g per 40g Nature Valley Peanut & Chocolate bar, while Costco UK lists 10g per 45g Eat Natural Peanut & Chocolate bar. Myprotein UK gives conflicting figures for its 50g TREK Original Oat flapjack, so check that pack. | For my break snack, I want to know how much protein is in the bar I would actually eat, rather than judge it by the product name. |
| Dietary fit and allergens | Check vegan, vegetarian, gluten-free or dairy-free wording on the exact variant, then read its ingredients and allergen statement. The Food Standards Agency says allergens present in prepacked food must be emphasised in the ingredients list. | A dietary claim may matter to me, but I also need to check peanuts, other nuts, soya or milk where relevant. A vegan or gluten-free label does not answer every allergen question. |
| Role in your break | Decide whether the bar is a planned snack or a spare for a difficult shift. Consider what other food and drink you can bring. | I want something portable without relying on a single bar as my whole plan for food during a long shift. |
Two bars labelled “protein” can have different serving weights and stated protein amounts, so the names alone are not a like-for-like comparison.
Read the current nutrition panel for protein per bar and the bar’s weight. Use per 100g information when comparing equal quantities.
The Nature Valley Peanut & Chocolate listing identifies peanuts, soya and milk as allergens and says it may contain nuts. Other bars in this category also have ingredient or allergen declarations that matter to individual shoppers.
For an allergy, check the exact physical pack’s ingredients and allergen statement before eating it; do not assume a vegan or gluten-free claim covers a different allergen.
A portable bar can cover a break snack, but it does not tell you what food will be available for the rest of a long shift.
Pack it as one part of your food plan and consider what else you can bring or access during your breaks.
Myprotein UK’s page for the TREK Original Oat flapjack says 9g protein in its descriptive copy but 10.2g per 50g in its nutrition table. Either figure would change a precise comparison with another bar.
Check the current pack’s serving size, protein value, ingredients and allergens before choosing it on that basis.
These examples show why the exact bar and pack matter more than a brand name when comparing protein amounts or dietary claims.

Tesco lists 10g per 40g Nature Valley Protein Peanut & Chocolate bar, and Costco UK lists 10g per 45g Eat Natural Protein Peanut & Chocolate bar. They state the same amount per bar but have different bar weights; check the exact pack before applying either figure to another size or variant.
Myprotein UK lists TREK Original Oat Protein Flapjack as vegan, dairy-free and gluten-free; Tesco lists nākd. Cocoa Hazelnut as vegan and gluten-free, with 7.2g protein per 45g bar. Check allergens on either pack, and confirm TREK’s protein figure on the current pack because its retailer page gives conflicting amounts.
Read the ingredients and emphasised allergens on the exact physical pack, including any “may contain” statement. The Food Standards Agency explains that allergens present in prepacked food must be emphasised in its ingredients list; a dietary claim such as vegan or gluten-free does not replace that check.
Plan a bar as a portable snack rather than your entire shift-food plan. Think about your breaks, what other food you can bring and what will be available while you work.
Follow the instructions on the exact pack. For example, the Joybuy information for Nature Valley Protein Peanut & Chocolate says to store it in a cool, dry place away from direct sunlight and to keep bars in their wrappers after opening the multipack.
