Choosing High-Protein Food: A Practical Guide to Snacks and Meals

Increasing your protein intake does not have to be complicated. However, the range of high-protein food is vast, from protein bars and high-protein granola to ready meals and tuna. Packaging often displays large numbers, but these do not always tell you what you need to know as a consumer.

So do not just look for the words “high protein”. Check the nutritional values, serving size, ingredients, allergens and how you plan to use the product. This helps you avoid paying for a snack that contains hardly any protein, or for a meal that does not fit your schedule.

Three common pitfalls when choosing high-protein food

1. A large protein figure that is not per serving

Some products state their protein content per 100 grams, even though the packaging contains several servings. For a protein bar, it is more useful to check how many grams of protein one bar contains. With granola, you also need to consider your actual serving size: 100 grams is often more than the amount you have for breakfast.

2. Less sugar does not automatically mean fewer calories

Protein bars often contain sweeteners, polyols, fats or a chocolate coating. A low sugar content can go hand in hand with a relatively high energy value. Some products also carry a warning that excessive consumption may have a laxative effect. Always check the full table showing energy, fat, carbohydrates, fibre, protein and salt.

3. A quick meal that does not feel complete

A meal that is high in protein is not automatically a complete meal. Also consider vegetables, fibre, carbohydrates and serving size. For example, a chicken dish with rice and vegetables may be more practical for lunch, while a protein bar is mainly intended as a snack between meals.

Which specifications should you check?

Protein per serving and per 100 grams

Use both values in the right context:

  • Per serving helps you plan your daily intake.
  • Per 100 grams makes it easier to compare products.
  • With drinks, pay attention to the volume, such as 350 ml.
  • With frozen meals, check whether the nutritional values are given per 100 grams or for the entire meal.

A product containing 20 grams of protein per bar is not directly comparable with granola containing 22 grams per 100 grams. The occasions when you use them are different too: you often eat granola with yoghurt or milk, while a bar is ready to eat straight away.

Ingredients and allergens

Check the allergens highlighted in bold on the label. Many protein bars contain milk, soya, peanuts or collagen. Granola may contain ingredients including oats, wheat, barley, spelt, almonds and hazelnuts. With fish products, fish is of course an important allergen.

Also pay attention to the type of protein source. This might include whey, milk protein, soya, wheat protein, fish, beef or chicken. If you follow a vegetarian diet, avoid lactose or do not want to use collagen, you need to look beyond the protein percentage alone.

Storage, preparation and shelf life

Individually wrapped bars and ambient tuna are practical for taking with you. A frozen meal, on the other hand, requires enough freezer space and an unbroken cold chain. Follow the instructions on the packaging:

  • Store frozen products generally at -18 °C or below.
  • Do not refreeze products once thawed.
  • Store opened drinks according to the stated instructions.
  • Check the use-by or best-before date on the individual packaging.
  • Cook meat thoroughly and follow the stated core temperature or cooking time.

These details determine whether a product genuinely fits into your work, exercise or travel routine.

High-protein snacks, granola or a complete meal?

The right category depends on when you plan to use it:

  • Protein bars: convenient on the go or straight after a workout, but check the polyols, calories and allergens.
  • High-protein granola: suitable for breakfast with yoghurt, quark or milk. Compare the protein and fibre per 100 grams, and look out for nuts and gluten.
  • High-protein tuna: easy to combine with bread, rice, salad or wraps. Check the salt content and storage instructions after opening.
  • High-protein meat products: useful as the basis for a hot meal. Check the quantity of meat, preparation method and freezing instructions.
  • Ready-made high-protein meals: save time, but compare the complete serving with your own meal requirements.

A product that requires little preparation may therefore offer more value than one with a higher protein figure that you rarely use. The same applies to sports nutrition: choose according to the occasion, serving size and your overall diet. High-protein products are an addition, not a replacement for a varied diet.

Frequently asked questions about high-protein food

What is a convenient high-protein meal after exercising?

Choose a meal with a clear protein source, such as tuna, chicken, beef, salmon or pulses. Combine it with vegetables and a source of carbohydrates such as rice, potatoes or pasta. A ready meal can be convenient when you are short on time; just check the nutritional values for the entire serving.

Are protein bars suitable for every day?

That depends on your overall diet and the composition of the bar. Check the amounts of protein, calories, fat, fibre, sweeteners and salt. Some bars state that excessive consumption may have a laxative effect. Use them as a practical snack rather than automatically treating them as a replacement for ordinary meals.

How long does high-protein food stay fresh?

This varies from product to product. Ambient bars and tuna generally have different storage requirements from frozen meals or fresh meat. Always check the date and instructions on the packaging. Additional rules may apply after opening, such as keeping the product refrigerated and consuming it within a specified period.
