Choosing snack bars without buyer’s remorse: how to find the right bar for every occasion

Snack bars may look alike, but they can differ considerably in ingredients, protein, sugar, allergens and portion size. A bar for eating on the go does not need to have the same qualities as a sports nutrition product. Terms such as “no added sugar”, “organic” or “high in protein” do not tell the whole story either.

With this practical guide, you can focus on the information that really matters. That makes it easier to choose between healthy snack bars, protein bars, muesli bars, nut bars and other snacks.

Three common pitfalls when choosing snack bars

1. A claim means little without the nutrition table

“High protein” or “low sugar” sounds clear, but always check how many grams per bar you are actually getting. A percentage per 100 grams may look favourable, while the individual portion is small. Also check the calories, carbohydrates, fats and fibre.

For example, a low-sugar bar may contain polyols or other sweeteners. Some products therefore carry a warning that excessive consumption may have a laxative effect. This is relevant information if you eat several bars every day.

2. “Natural” or “organic” does not automatically mean low in sugar

Organic snack bars can still contain a lot of energy or natural sugars from ingredients such as agave syrup, dates or raisins. For example, Zonnatura states that its nut bar with apple and cinnamon is sweetened exclusively with agave syrup. According to the product information, this bar contains 24 grams of sugar per 100 grams.

That does not make the product unsuitable, but it does make it different from a sugar-free bar. First decide what you need the snack for: a sweet treat, a filling snack or extra protein after exercise.

3. Dietary labels do not replace checking allergens

A product may appear vegan, gluten-free or vegetarian, but always check the full ingredients list and allergen information. Look out for milk, soya, peanuts, nuts, gluten-containing cereals and gelatine. “May contain traces of” is also important if you have an allergy.

Protein bars may contain milk protein, whey, casein and sometimes collagen. These ingredients are not suitable for a vegan diet. An oat bar may be described as gluten-free, but check that the packaging and current product information confirm this too.

Which specifications should you compare?

1. Nutritional value per serving

Do not compare products only per 100 grams. Also note the weight of each bar:

  • Small bars weighing 23 to 30 grams: convenient as a light snack or with your coffee.
  • Bars weighing 50 to 60 grams: often more suitable when you are looking for extra protein or energy.
  • Multipacks: practical for work, your gym bag or snacks on the go, but check the overall shelf life and portion size.

In practice, a 60-gram bar containing 20 grams of protein provides more protein per bar than a smaller muesli bar, even if the percentage per 100 grams appears similar.

2. Protein source and quantity

With protein bars, the number alone is not the only thing that matters. Look at the source too. Milk protein, casein and whey are animal-derived ingredients. Collagen is also unsuitable for vegans and vegetarians. Plant-based bars may use soya, peas, seeds or nuts, for example.

The 50-gram Xxl Nutrition High Protein Bar Chocolate lists 25 grams of protein per bar, 179 kcal and 0.7 grams of sugar per bar. According to the product information, the product contains milk protein and collagen hydrolysate, among other ingredients. This makes the bar relevant for athletes looking for a compact source of protein, but not for vegans.

3. Ingredients, sweeteners and allergens

The order of the ingredients shows which components are present in relatively large amounts. Also check:

  • whether sugar, syrup, dates or agave appear high on the list;
  • whether sweeteners such as maltitol or sucralose have been used;
  • how much fibre the product contains;
  • whether gluten, milk, soya, peanuts or nuts are present;
  • whether the packaging is individually sealed.

A low sugar value therefore does not automatically mean that a product is low in calories. Nut bars, for example, can provide relatively high amounts of fat and energy, while still being convenient as a compact snack.

Storing and taking snack bars with you

Store bars according to the instructions on the packaging: usually in a cool, dry place away from direct sunlight. A hot car or damp gym bag can affect the texture and flavour. Reseal opened packaging properly and do not use the product if the packaging is damaged.

Individually wrapped bars are convenient for snacks on the go. At home, you may want to consider larger packs, as long as you decide on the portions in advance. This helps prevent a multipack from automatically leading to several bars being eaten one after another.

Frequently asked questions about snack bars

What is a suitable snack bar after exercise?

Look at the protein content per bar, the size and the ingredients. Protein bars containing around 18 to 25 grams of protein per bar may suit someone who wants extra protein after a workout. According to the brands’ own product information, some bars are intended for use around training sessions; they are not a substitute for a varied diet.

Are sugar-free snack bars always a healthy choice?

No. “No added sugar” does not mean that a bar contains no carbohydrates, calories or sweeteners. Check the full nutrition table and ingredients list. With bars containing polyols, also pay attention to the warning about excessive consumption.

Which bars are suitable for a vegan or gluten-free diet?

Only choose a bar whose current packaging and product information clearly state this. For vegan products, check for milk, whey, casein, collagen and gelatine. With gluten-free bars, you should also look out for oats, wheat, barley and possible traces information. Labels are a starting point; the allergen list determines whether the product is suitable for your situation.
