Choosing healthy snack bars: how to compare protein, sugar and ingredients

Healthy snack bars often look similar, but their nutritional value can vary considerably. A bar containing little sugar does not automatically provide much protein. A muesli bar made with wholegrains may contain more carbohydrates than you expect. And a nut bar made with natural ingredients is often nutritious, but also relatively high in calories.

For athletes, fitness enthusiasts and active adults, the right choice therefore depends on when you plan to eat it. Are you looking for protein bars for after exercise, a small snack for when you’re out and about, or a high-fibre bar between meals? Check the label first and look beyond the front of the packaging.

Three pitfalls when choosing healthy snack bars

1. Confusing ‘no added sugars’ with sugar-free

A product with no added sugars may still contain naturally occurring sugars, for example from dried fruit, milk ingredients or grains. The Hero B'Tween Muesli Bar Zero White Chocolate, for instance, lists 1.7 grams of sugar per 100 grams, alongside 42 grams of polyols. The claim ‘no added sugars’ therefore does not mean that the bar has no sweet taste or carbohydrates.

Also look out for polyols such as maltitol, glycerol and sorbitol. According to the product information, excessive consumption may have a laxative effect. If you are sensitive to these ingredients, it is best to start with one bar.

2. Looking only at the protein figure

A protein bar containing 20 or 25 grams of protein may suit an active lifestyle, but it can also contain plenty of fat, carbohydrates or calories. According to the product information, the Nutramino XL Protein Bar in the multipack contains 25 grams of protein and around 19 grams of sugar per bar. This may be a deliberate choice after intense exercise, but it is not the same as a low-carbohydrate bar.

Always compare the values per serving. The table per 100 grams is useful for comparing products fairly, but snack bars vary considerably in size.

3. Overlooking ingredients and allergens

A short marketing description does not always tell you what is really in a bar. Check the ingredients list for, among other things:

  • Milk, soya, peanuts and nuts;
  • cereals containing gluten, such as wheat, barley, oats or spelt;
  • sweeteners and polyols;
  • collagen hydrolysate, if you want to avoid animal-derived ingredients;
  • possible traces of other allergens.

Recipes and allergen information may change. Always check the packaging when buying, especially if you have a known allergy or intolerance.

Which nutritional values matter?

Protein: for sport and satiety

Protein bars and high-protein bars often contain between 15 and 25 grams of protein per bar. According to the product information, the XXL Nutrition High Protein Bar Chocolate provides 25 grams of protein per 50-gram bar. Barebells Protein Bars Caramel & Cashew list 20 grams of protein per 55-gram bar.

This makes these bars practical after exercise or between meals. They are not a substitute for a varied diet. Also consider the source of the protein: milk protein, whey, soya, peanuts and collagen have different properties and are not suitable for everyone.

Sugar and polyols

If you want to eat less sugar, look at the ‘of which sugars’ line as well as the ingredients. Products containing maltitol, sorbitol or erythritol may be low in sugar while still tasting sweet. Also check the warning about a possible laxative effect in cases of excessive consumption.

‘Sugar-free bars’ and bars described as ‘low sugar’ are therefore terms you should consider alongside the complete nutrition table. A low sugar value alone says nothing about calories, fat or fibre.

Fibre, calories and serving size

For healthy snacks when you’re out and about, a clearly defined serving is useful. According to the product information, Bites We Love Chewy Oat Bars Chocolate contains 8.6 grams of fibre, 115 kcal and 2.7 grams of protein per 30-gram serving. Bolletje Cereal Bars with Sweetened Dried Cranberries list 14 grams of fibre per 100 grams, but also 17 grams of sugars per 100 grams.

A high-fibre bar can be a convenient choice between meals, but make sure you drink enough and increase your fibre intake gradually if you are not used to it. Nut bars often contain unsaturated fats, but nuts, syrup or dried fruit can also make them high in energy.

How to choose the right bar for your needs

  • For when you’re out and about: choose individually wrapped bars with a clearly stated serving size and a shelf-stable composition.
  • After exercise: look at the protein per bar first. Bars containing 20 to 25 grams of protein are practical, but also compare calories and sugar.
  • For less sugar: check sugars, polyols and carbohydrates together. ‘No added sugars’ is no guarantee of low carbohydrate content.
  • For more fibre: compare the fibre value per serving. Bites We Love and Holie list relatively high fibre values in their product information.
  • For allergies: read the allergens highlighted in bold on the packaging and also check the ‘may contain’ warning.

Frequently asked questions about healthy snack bars

Are healthy snack bars suitable for everyday use?

That depends on their composition and your overall diet. A bar can be a practical addition between meals, but vary your choices with ordinary foods such as fruit, yoghurt, wholemeal bread or unsalted nuts.

Which bar is suitable after exercise?

Look at protein per serving, calories and the amount of sugar. A high-protein bar containing 20 to 25 grams of protein can be practical after a workout. Carbohydrates may also be relevant after prolonged or intensive exercise. The right choice depends on the length of your workout and your usual meal planning.

How long do snack bars keep?

The best-before date is shown on the packaging. Store bars according to the manufacturer’s advice, usually in a cool, dry place away from direct sunlight. Do not leave an opened pack exposed unnecessarily, and do not use a product if the packaging is damaged.
