Protein-Rich Foods: Top Sources for Fitness & Health

TL;DR:

Many people in Switzerland do not know their exact protein requirements and are unsure which foods provide them with optimal nutrition. The most important sources include animal products such as cottage cheese, eggs, and fish, as well as plant-based alternatives such as seitan, lentils, and tofu, which can be combined effectively. Evenly distributing protein intake throughout the day, tailored to individual needs, supports muscle growth, recovery, and long-term health.

Protein is the building material your body needs every day—for muscles, hormones, a strong immune system, and rapid recovery after training. Yet many people in Switzerland face the same problem. They know they need more protein, but not which foods truly provide it, how much per serving is realistic, and whether plant-based sources work just as well as meat or fish. This article clears up the uncertainties, shows you the ten best protein-rich foods in a clear table, compares animal-based and plant-based sources based on current studies, and gives you practical tips you can implement in your everyday life.

Important Criteria for Protein-Rich Foods

Before you fill your shopping list with chicken breast and lentils, it is worth clarifying a few basic questions. How much protein do you actually need? And which foods really provide what your body can use?

How Much Protein Per Day Is Realistic?

According to the DGE & EFSA, protein requirements vary significantly depending on life stage and activity level: The DGE generally recommends 0.8 g per kilogram of body weight per day, while the EFSA recommends 0.83 g/kg for Switzerland. For athletes and physically active people, requirements increase to 1.2 to 2.2 g/kg of body weight per day. People aged 65 and over also benefit from an increased intake of 1.0 to 1.2 g/kg, as muscle loss increases with age.

This may sound abstract, but it becomes concrete: A person weighing 70 kg who trains three times a week needs between 84 and 140 grams of protein daily. That is roughly four servings of cottage cheese or three large chicken breasts. Knowing the optimal protein requirement is the first step before comparing foods.

Calculate protein per serving, not just per 100 g
Consider biological value (egg = reference value 100)
Check the amino acid profile: Are all 9 essential amino acids included?
Plan distribution throughout the day: 20 to 40 g per meal every 3 to 4 hours
Consider individual factors: age, training goal, dietary pattern

Statistics: According to the EFSA recommendation for Switzerland, an 80 kg athlete needs between 96 and 176 grams of protein daily for optimal performance and recovery.

Biological value (BV) refers to how well your body can convert the protein in a food into the body's own protein. The hen's egg has a BV of 100 and is considered the reference value. Animal sources often range between 70 and 100, while plant sources are somewhat lower. However, clever combinations can offset this.

Pro tip: Use the Swiss Nutrient Database of the Federal Food Safety and Veterinary Office (FSVO) to look up the exact protein content per serving for every Swiss food. There, you can sort foods directly by protein and plan your shopping precisely.

The distribution of protein intake throughout the day is just as important as the total amount. The body can only use a limited amount of protein efficiently for muscle building per meal. That is why it makes more sense to eat five meals with 25 to 35 g of protein each than to consume 100 g all at once once a day. Anyone interested in protein in sports nutrition will find further information there on timing and quantity.

Now that it is clear why protein and its quantity are important, let’s take a look at the best natural protein sources.

The Top 10 Protein-Rich Foods by Serving

Many people compare foods based on 100 g. This sounds logical, but is not very helpful in everyday life. Nobody eats 100 g of Parmesan in one sitting. What matters more is: How much protein is in a realistic serving?

The following table is based on Swissmilk protein sources, a nationally recognized Swiss nutrition resource, and shows the top 10 by actual protein content per serving.

Food	Serving	Protein (g)	Special feature
Seitan	120 g	33,6 g	Highest value among vegan sources
Lean beef	110 g	23,5 g	Rich in zinc and B12
Fish (e.g., salmon)	110 g	23,0 g	Includes omega-3 fatty acids
Cottage cheese	175 g	21,7 g	Affordable, low-fat, Swiss favorite
Tempeh	120 g	21,1 g	Fermented, easy to digest
Lentils (cooked)	200 g	18,0 g	High fiber content
Plain yogurt (Greek)	200 g	17,4 g	Probiotic, for gut health
Chickpeas (cooked)	200 g	15,6 g	Versatile to combine
Egg	2 pieces	12,6 g	Reference protein source (BW 100)
Low-fat quark	150 g	16,5 g	Casein source for the night

Cottage cheese and quark are particularly popular in Switzerland because they are affordable, versatile, and available in every supermarket. Cottage cheese provides 21.7 g of protein per serving with a low fat content. Quark is rich in casein, a slowly digested protein that works particularly well as an evening snack.

Seitan surprises many people: This vegan wheat-protein alternative provides more protein per serving than meat or fish. The catch: Seitan does not contain a complete amino acid profile. It is low in lysine, which is why combining it with legumes is advisable. Anyone who wants to learn more about protein sources at a glance will find a useful overview there.

Prefer whole-grain options for grain products; they also provide fiber
Fresh fish from Swiss aquaculture is locally and freshly available
Greek yogurt contains twice as much protein as regular yogurt
Lentils and chickpeas are ideal for cooking and portioning in advance
The protein information for Swiss foods can be accessed directly online

Pro tip: Buy cottage cheese, quark, and Greek yogurt in large containers. This saves money and makes portioning easier. A 500 g container is enough for two to three protein-rich snacks or meals.

After this specific overview, it is worth looking at the comparison: What really distinguishes animal and plant sources?

Someone is preparing meals for the week, paying particular attention to protein-rich foods.

Animal Vs. Plant Protein Sources: Myths and Facts

Few topics divide the nutrition world more: Do you need meat and dairy products for genuine muscle growth, or is a plant-based diet enough? The answer is more nuanced than many people think.

What the Science Really Says

A widely cited analysis shows: There is no significant difference between animal and plant protein sources for muscle growth when the amount and distribution are right. This is an important finding. It is not the protein’s origin that matters, but the completeness of its amino acid profile and the total amount.

Criterion	Animal protein	Plant-based protein
Biological value	High (70 to 100)	Medium (50 to 80)
Complete amino acid profile	Yes (usually)	Often only through combination
Digestibility	High	Varies (legumes are somewhat lower)
Health risks	Red meat: cardiovascular risk when consumed in excess	Minimal
Nutritional cofactors	B12, zinc, iron	Fiber, antioxidants
Environmental impact	Higher	Significantly lower
Cost-effectiveness	Medium to high	Often more affordable

“Those who cleverly combine plant-based protein sources benefit not only from equivalent muscle growth, but also from better gut health and a reduced risk of inflammation."

Myth 1: Plant-based protein does not build muscle. False. Studies clearly disprove this. What matters is that all nine essential amino acids are present in sufficient quantities. This can be achieved through targeted combinations. Tofu with brown rice, lentils with quinoa, or combinations of seitan and tempeh can provide the full spectrum.

Myth 2: Animal protein is always healthier. This is not universally true. Too much red and processed meat increases the risk of cardiovascular disease and certain types of cancer. Swiss dietary recommendations advise limiting red meat to a maximum of two to three portions per week.

Vegans should definitely supplement vitamin B12 and vitamin D
Iron from plant-based sources is absorbed better when vitamin C is consumed at the same time
Lysine is the most critical amino acid in seitan. Supplement it with edamame or peas
Quinoa is one of the few plant-based sources with a complete amino acid profile
Those who prefer plant-based protein sources should know the principles of combining them

The good news for everyone who eats a mixed diet: In Switzerland, the selection of high-quality animal and plant sources is excellent. Quark, cottage cheese, eggs, salmon, lentils, tofu, and tempeh are available in every large supermarket. This makes it easy to combine them flexibly while meeting all individual protein needs.

To make the information even more tangible, here is how you can deliberately integrate suitable foods into your everyday life.

Practical Tips for Everyday Life

Knowing about protein is one thing. Putting it into practice every day is another. Many people do not fail because they lack information, but because they lack a routine. Here are concrete strategies that work.

Spread Protein Intake Throughout the Day

The most important principle: Plan every meal around a protein source. This is easier than it sounds. According to Swissmilk, a protein intake of 20 to 40 g per serving every 3 to 4 hours is recommended for fitness goals. Consistently following this approach will help you reach your daily requirement almost automatically.

Breakfast: Greek yogurt with nuts and berries (approx. 20 g protein) or two eggs with whole-grain bread
Morning snack: Cottage cheese with vegetable sticks or a handful of edamame
Lunch: Lentil and quinoa bowl with vegetables or chicken breast with brown rice
Afternoon snack: Quark with fruit or a hard-boiled egg
Dinner: Salmon with broccoli and sweet potato or tempeh and vegetable stir-fry

This pattern provides a steady supply of amino acids throughout the day and keeps blood sugar stable. This supports not only muscles but also concentration and mood. Anyone who wants to optimize their macronutrients should always view protein as the foundation of every meal.

Portion Management Without an App or Scale

You don't need a kitchen scale to estimate portions. Your hand is your best measuring tool:

Palm = approx. 80 to 120 g meat or fish (20 to 25 g protein)
Clenched fist = approx. 150 to 175 g cottage cheese or yogurt
Thumb = approx. 15 g nuts or cheese
Cupped hand = approx. 40 g legumes (dried)

Pro tip: Anyone who wants to calculate their daily protein intake will find a practical guide there, including specific examples for different body weights and training goals.

Special situations and target groups

For workout days, the rule is: Consuming protein around your workout maximizes the muscle-building effect. Ideally, eat a small protein-rich meal (15 to 20 g) 30 to 60 minutes before training and a larger portion (25 to 40 g) immediately afterward. This could be quark with berries before training and cottage cheese with rice cakes afterward. Simple, affordable, effective.

Older people need more attention when planning their protein intake. From the age of 50, muscle protein synthesis declines, which means that the body uses protein less efficiently. Anyone who wants to learn more about protein in later life should read the recommendations there. Small, protein-dense meals are particularly useful in this case.

For plant-based diets, the complementary protein principle applies: Legumes plus grains provide a complete amino acid profile. Specific combinations with benefits:

Lentils and quinoa in a bowl
Chickpeas and whole-grain bread as a hummus sandwich
Black beans and corn in a burrito
Red lentils and rice in dhal
Tofu and sesame in an Asian wok dish

In conclusion, we would like to offer our own perspective: Why everyday implementation and individualization are crucial.

Our Perspective: What Really Matters in a High-Protein Diet

The world of nutrition is constantly introducing new superfoods, hypes, and promises. Hemp protein, insect flour, pea protein isolate. Attention is often focused on what is new and unusual. But in practice, the most exotic food does not determine success or failure. Routine does.

We observe the same pattern among thousands of users: People who succeed in the long term do not eat perfectly. They eat consistently. Someone who incorporates cottage cheese, eggs, lentils, and chicken every day reaches their protein targets more reliably than someone who spends weeks searching for the perfect protein stack while neglecting the basics.

A second point that is often overlooked: Switzerland’s diverse food offerings are a real advantage. From high-quality Swiss cheese and seasonal fish to organically certified legumes, there is an excellent foundation available here. Use it. You do not need imported products or expensive supplements if you combine local sources cleverly.

A common mistake is perfectionism. Many people start well, then have a more difficult week and give up completely because they failed to reach their protein target on one day. This is counterproductive. It is better to be consistent 80% of the time and remain flexible during the other 20%. Protein is not a medication dose that has to be exact to the minute.

At mybody®, we firmly believe that individual data make the difference. Knowing your exact metabolic type, genetic predispositions, and nutrient status allows you to apply protein recommendations much more precisely. A general recommendation such as “1.5 g/kg” is a good starting point. But if you know that you are genetically predisposed to breaking down muscle more quickly or have an increased need for certain amino acids, you can take more targeted action. A sports-appropriate diet is recommended as a foundation.

Our conclusion: Rely on proven foods, use Swiss nutritional sources as a guide, distribute protein throughout the day, and stick with it over the long term. That delivers more than any short-lived trend.
