Choosing muesli bars without falling into marketing traps: how to find the right snack bar

A bar for on the go, at work or after exercise seems like a simple purchase. Yet muesli bars, cereal bars and protein bars can vary considerably in ingredients, portion size and allergens. The eye-catching front of the packaging does not always tell the whole story.

Pay particular attention to three common pitfalls:

• “No added sugar” does not mean sugar-free. A bar may still contain naturally occurring sugars. Sweeteners and polyols, such as maltitol, can also affect its nutritional value and digestion.
• A high protein or fibre percentage does not tell you everything. Check whether the value is given per 100 grams or per bar. A small bar may provide considerably less protein or fibre per portion than the front of the pack suggests.
• “Organic” or “gluten-free” claims should be checked on the label. Look at the ingredients list and allergen information, particularly with nut bars, chocolate bars and products intended for a family with food allergies.

Which details should you check before buying?

1. Nutritional value per portion

The table per 100 grams is useful for comparing products. For everyday use, however, the portion size is also important. A bar weighing 25, 30, 50 or 60 grams gives you a different picture of its calories, carbohydrates, fats and protein.

Look out for:

• energy per bar;
• protein content in protein bars;
• fibre content in high-fibre bars;
• sugar, polyols and other sweeteners;
• saturated fat and salt.

For example, a product with little sugar may contain relatively high levels of polyols. According to the product information, Hero B’tween Zero carries a warning that excessive consumption may have a laxative effect. That does not automatically make these bars unsuitable, but it is worth bearing in mind if you plan to eat several bars in one day.

2. Ingredients in the correct order

Ingredients are generally listed on the label in descending order by quantity. If oats, wholemeal flour, nuts or high-fibre ingredients appear near the top, they make up an important part of the recipe. Also look out for:

• syrups and sugar used as binding agents;
• chocolate or coating;
• chicory root fibre, inulin or tapioca fibre;
• palm or coconut oil;
• sweeteners and humectants.

A bar containing nuts and seeds may have more fat than a classic cereal bar. That is not necessarily a disadvantage, but it does affect the energy value. For example, Zonnatura Organic Nut Bar contains peanuts, almonds and agave syrup, and lists 34 grams of fat and 24 grams of sugars per 100 grams.

3. Allergens and dietary requirements

Always check the allergens highlighted in bold on the packaging. Many muesli bars contain oats, wheat, barley, milk, soya, peanuts or other nuts. “Gluten-free bars” require extra attention: check that the product and its packaging actually carry this claim. The product information supplied for some bars contains contradictory allergen information. If in doubt, use the current label as your guide.

For children at school or in the office, a nut-free option may be important. For sportspeople, protein content and portion size may matter more than organic certification. There is therefore no one-size-fits-all choice; the occasion determines which specifications are most important.

Muesli bars for on the go: practical buying tips

Choose individually wrapped bars if you keep them in a work bag, gym bag or school bag. Check the best-before date and store the packaging according to the label, usually in a cool, dry place away from direct sunlight.

For a snack during exercise, portion size, carbohydrates and protein are often more important than a claim on the front of the pack. At home, a multipack with different flavours may offer better value. If you are looking for organic bars, nut bars or bars with no added sugar, it is worth comparing the certification, ingredients and nutritional value side by side.
