When we want to get rid of excess weight or improve our fitness, we often choose diets high in protein and low in carbohydrates. While high-protein diets are often categorized as a "trend," understanding these macronutrients is actually the key to long-term health. Reducing carbohydrates in favor of protein not only helps burn fat but also makes the diet more efficient and satiating.
In this comprehensive guide, we will explore which foods are carbohydrates and which are proteins, and what the optimal sources of these key macronutrients are. They not only provide basic energy but are vital for maintaining vitality and overall health. Join us in discovering the nutritional options that make our diet balanced and satisfying.
What are proteins?
Proteins are the most important of all macronutrients for humans. They are complex macromolecules present in all living organisms, composed of different amino acids. They have great nutritional value and are directly involved in chemical processes necessary for survival, immune system preservation, and digestion.
Amino acids are the basic building blocks of proteins. They are essential for the growth and maintenance of cells and tissues. They are classified as essential and non-essential. The body can produce non-essential amino acids on its own, while essential ones must come from our diet.
Proteins are found in muscles, bones, skin, hair, and practically every part of the body. They trigger many chemical reactions, including hemoglobin which carries oxygen in our blood. At least 10,000 different proteins make us who we are. During our life, proteins are constantly being repaired and replaced through protein synthesis. To keep up with this process, we need a continuous supply of amino acids from high-quality sources.
Protein recommendation for active individuals:
When diet alone isn't enough, high-quality whey protein is the most efficient way to fulfill your daily needs.

What are carbohydrates?
Carbohydrates have had a bad reputation for decades, often linked to obesity and Type 2 diabetes. However, they are your body's main source of energy. They consist of sugars, starches, and fibers. The key is distinguishing between simple carbs (fast sugars that spike insulin) and complex carbs (which provide steady energy).
When you eat "naked" carbohydrates like white bread or sweets, glucose molecules hit your bloodstream rapidly, causing spikes and then crashes. This can be fixed by adding proteins, fats, or fibers to slow down absorption. For example, instead of plain pasta, add spinach, chicken, and olive oil.
Complex Carbohydrates - Best Sources
Complex carbs are composed of long chains of sugar molecules. They break down slowly, providing a long-lasting source of energy. Preferred sources include:
- Whole Grains: Brown rice, oats, barley, buckwheat, and quinoa.
- Legumes: Beans, lentils, and peas (rich in fiber).
- Vegetables: Broccoli, carrots, kale, and sweet potatoes.
- Fruits: Apples, berries, and pears (contain fiber to slow sugar absorption).
Pharmacist's advice: How to avoid the "Sugar Crash"?
To maintain stable energy, never consume simple carbohydrates alone. Always pair them with fiber or protein. If you struggle with insulin sensitivity, glucose regulators can be a helpful addition to your routine to keep your metabolism in balance.
Frequently Asked Questions (FAQ)
1. Do bananas contain protein?
Yes, for a fruit, bananas are quite unique. They contain about 4g of protein per 100g, along with being a great source of potassium.
2. Can I eat too much protein?
If you exceed 2–3g of protein per kilogram of body weight daily, your body may convert the excess into fat, which could disrupt your metabolic balance.
