Choosing high-protein foods: a practical guide to snacks and easy meals

If you’re looking for high-protein foods, you’ll usually want to make a quick choice: a protein bar for when you’re out and about, a filling lunch after exercise or a ready-made high-protein meal for a busy working day. But a big word like “protein” on the packaging doesn’t tell you everything. Protein content, portion size, allergens and preparation method all determine whether a product really fits your routine.

As a Joybuy Product Recommendation Officer, I check product information against verifiable features. That way, you can avoid paying for marketing terms alone.

Common pitfalls with high-protein products

1. Don’t look only at the protein percentage

A product may be called “high-protein” even though a full portion contains relatively little protein. So check:

  • the grams of protein per portion;
  • the grams of protein per 100g;
  • the actual portion size;
  • calories, fat, carbohydrates and salt.

For example, a meal with 5.6 grams of protein per 100g may still be a handy quick meal, but it isn’t comparable to a protein bar containing around 20 grams of protein per bar.

2. “Sugar-free” or “low sugar” doesn’t automatically mean low in calories

Protein bars often contain sweeteners such as maltitol, sorbitol, erythritol or sucralose. According to product information from various brands, excessive consumption of polyols may have a laxative effect. So check the ingredients list and nutrition table, not just the front of the packaging.

Protein bars can also be relatively high in fat and calories. They’re most useful as a snack, rather than as an automatic replacement for a varied meal.

3. Poor storage can take away the convenience

Frozen products need to be stored in a freezer at a suitable temperature. Products such as meat, chicken meals and fish dishes must remain frozen until you’re ready to prepare them. According to the product instructions, they usually shouldn’t be refrozen once thawed.

For high-protein products with a long shelf life, also check the packaging for damage and always follow the information on the actual label. The packaging may contain more up-to-date or more detailed information than an online product page.

Important specifications for high-protein foods

Protein per portion and per 100g

For snacks, protein per bar is often the most useful measure. For example, a 55g bar containing 20.4 grams of protein will fit in a bag or gym locker. For granola, meat and tuna, protein per 100g is a better way to compare products fairly.

Also consider the source:

  • milk, whey and casein protein in protein bars;
  • tuna or other fish in high-protein fish products;
  • beef or chicken in high-protein meals;
  • soya, grains, seeds and nuts in protein granola;
  • lentils and other pulses in vegetarian meals.

Allergens and dietary preferences

Check which allergens are highlighted in bold on the label. Many protein bars contain milk and soya; some also contain peanuts, nuts, gluten or collagen. For example, a bar containing milk protein and bovine collagen isn’t suitable for a vegan diet.

Ready-made meals may also contain fish, celery, sulphites, peanuts or egg. So always read the product information before buying and eating a product.

Preparation, storage time and when to eat it

Choose a product that suits when you’ll need it:

  • When you’re out and about: individually wrapped protein bars or tuna that doesn’t need draining.
  • Breakfast: protein granola with yoghurt, quark or a plant-based alternative.
  • Quick lunch: tuna, a high-protein bowl or a microwave meal.
  • Dinner: frozen meals, meatballs, chicken or beef.
  • After exercise: a snack with a known portion size and clear nutritional information.

A convenient meal is less useful in practice if you can’t store or prepare it in time.

Including high-protein foods in your day

A practical daily plan could look like this:

  • Breakfast: protein granola with yoghurt, quark or an alternative that suits your diet.
  • Lunch: high-protein tuna in a salad, wrap or sandwich, or a ready-made tuna bowl.
  • Snack: a protein bar with a clearly stated portion size.
  • Dinner: high-protein meat, fish or a vegetarian meal with lentils and vegetables.
  • Busy days: a frozen meal that’s easy to prepare in a pan or microwave.

A product shouldn’t be judged on its protein content alone. Also consider fibre, salt, fat, carbohydrates, ingredients and how much veg or pulses it contains. That way, healthy protein snacks and high-protein meals can fit more easily into your overall diet.

Frequently asked questions about high-protein foods

What counts as a high-protein food?

Options range from fish, meat, eggs, dairy and pulses to protein bars, granola and ready-made meals. Always compare the protein content per 100g or per portion. Without a nutrition table, the term “high-protein” doesn’t tell you how much protein you’ll actually get.

Are protein bars suitable for everyday use?

That depends on your overall diet, the ingredients and the portion size. Check the sweeteners, allergens, calories and fat content. According to the packaging, products containing polyols may have a laxative effect if consumed in excess.

How should I store ready-made high-protein meals?

Follow the storage and preparation instructions on the label. Frozen meals must stay frozen until you’re ready to use them and generally shouldn’t be refrozen once thawed. Once opened or thawed, they often have a limited storage time in the fridge.
