Buying snacks online: how to choose between bars, sweets and high-protein snacks

Buying snacks online seems straightforward, but product packaging often highlights one standout feature. A bar might say “no added sugar”, for example, while still containing sweeteners and polyols. And “high-protein” doesn’t automatically tell you how many calories it contains, what ingredients it uses or whether it’s right for the occasion.

Use these practical checks to compare sweet snacks, low-calorie snacks, protein bars and snacks for on the go, using information you can verify.

Common pitfalls when buying snacks online

1. Assuming “sugar-free” means low in calories

A product with 0 grams of sugar may still contain carbohydrates, sweeteners or a relatively high number of calories. Klene Sweet Suns, for example, lists 0 grams of sugar per 100 grams, but contains 53 grams of polyols. Consuming too many polyols can have a laxative effect. So check more than just the “of which sugars” line: look at total carbohydrates and the sweeteners used too.

The claim “no added sugar” on muesli bars also has its limits. It doesn’t mean the product contains no naturally occurring sugars. Always check the full nutrition table.

2. Mixing up nutrition information per 100 grams and per serving

A pack may show a low figure per serving, while the nutrition table is based on 100 grams. That makes comparisons tricky. For each snack, note:

  • the amount per serving;
  • the energy in kcal;
  • the protein content;
  • the amount of sugar and polyols;
  • the total carbohydrates;
  • the fibre and salt content.

A small 125-gram jelly snack, for example, may contain 35 kcal, while a large 50 to 74-gram protein bar provides considerably more energy. Each could suit a different occasion.

3. Treating a protein claim as a guarantee of a light snack

High-protein snacks aren’t necessarily low in calories. According to the product information, the Nutramino XL Protein Bars in the variety bundle contain 25 grams of protein and around 284 kcal per 74-gram bar. That could work as a substantial snack, but may not be the best choice if you’re looking for a light sweet treat.

Also check for allergens. Milk, soya, gluten, peanuts and nuts are common in protein bars, biscuit bars and nut snacks.

Three important checks

1. Look at the nutritional values in context

First compare products per item or pack to see what you’ll actually eat. Then use the values per 100 grams to compare different sizes fairly.

Examples:

  • Low-calorie snacks: check the kcal per serving and the actual serving size.
  • Protein bars: check the protein as well as kcal, fat and sugar.
  • Sugar-free sweets: look out for polyols, sweeteners and warnings about excessive consumption.
  • Jelly snacks: check whether the product contains sugar, fructose or sweeteners.

2. Check the ingredients and allergens

Ingredients are listed in descending order by weight. If glucose-fructose syrup, maltitol or sugar appears near the top of the list, that’s worth taking into account. If you’re choosing a nut snack, check which nuts it actually contains and whether the label says “may contain”.

EU rules require the 14 main allergens to be clearly listed. Still, check the label every time you buy, as recipes can change.

3. Match the format and shelf life to how you’ll use it

Individually wrapped bars are handy for work, school, travel or a gym bag. A resealable bag is more convenient at home, but makes it easier to eat several servings without realising. Also check the storage instructions, whether the packaging is damaged and the date on the pack.

A product high in polyols may not be the best choice just before a long drive or a meeting. Read the warning on the packaging and follow the recommended usage instructions.

Looking for more options?

We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and current European safety requirements.

Which snack is right for each occasion?

  • For on the go: choose individually wrapped protein bars, muesli bars or biscuit bars, and check that the packaging stays securely closed.
  • After exercise: compare protein per serving with calories and sugar. A high protein content alone doesn’t determine whether a product fits your diet.
  • For a light sweet treat: jelly snacks can make a small portion. Check the sugar, sweeteners and storage instructions.
  • For sweet lovers: sugar-free sweets such as Klene may contain less sugar, but often still provide polyols. Enjoy them in line with the instructions on the pack.
  • For a crunchy snack: nut snacks and brittle-style products can have a distinctive flavour and texture, but check the serving size and fat content.

Frequently asked questions about buying snacks online

What are some suitable low-calorie snacks?

Check the kcal per actual serving, not just terms such as “light” or “zero”. A jelly cup with 35 kcal could be a different choice from a protein bar with 179 kcal. Also check the sugar, sweeteners and saturated fat.

Are sugar-free snacks automatically healthier?

No. Sugar-free usually means sugar has been replaced with sweeteners or polyols. Check the full nutrition table and read any warnings about excessive consumption. If you’re choosing liquorice sweets, also check the advice for people who are sensitive to a high intake.

Which snacks are handy for work or when you’re on the go?

Individually wrapped bars and cups are practical and easy to portion. For a longer day, you could combine a few options, such as a muesli bar, a high-protein snack and a small jelly snack. Check allergens, shelf life and storage conditions beforehand.
