Chapter II
Proteins
— the brick of life — and its hidden origin —
« Meat does not contain proteins — it only carries them. The source is the plant. »
No brick, no repair, no defense without them: proteins carry the solidity of life. This chapter begins by understanding them — what they are, why they are vital — then traces back to their origin, more surprising than we think. Finally, we see where the plant world offers them in abundance, and the quiet genius of seeds, pulses and hemp.
What is a protein?
The flame of the previous chapter burns a fuel — but what is the boiler itself made of? Before the amino acids, let us ask the real question: where does a body's strength come from, its capacity to repair, to grow, to defend itself? The answer overturns a stubborn belief. Strength is not born in meat: it is born in the plant, which the animal merely copied. This chapter goes back to the source — and everything, from muscle to immunity, is lit by it.
A chain of amino acids — twenty letters that make up every functional molecule in the body. An enzyme, a hormone, a muscle fiber, an antibody, the hemoglobin that carries oxygen: it is all protein.
Our body assembles and recycles them constantly — they carry all of our repair, all of our growth, all of our immune defense.
Why it matters
Of the twenty amino acids, nine are called essential: our body cannot make them. It must receive them through food, every day.
A body is built with its food.
Vibrant — it becomes high-performing.
Poor — it becomes a permanent construction site.
When the body receives its nine essential amino acids every day: supported muscles, active immunity, luminous skin, stable energy, strong hair. The body repairs, builds, defends — it knows exactly what to do as soon as we offer it the matter.
The hidden origin of proteins
What I wish I had learned at school: all proteins are born in the plant kingdom — plants, algae and certain microbes such as spirulina. They alone know how to build an amino acid from the light of the sun, the carbon of the air and the nitrogen of the earth. The rest of the living world — we, the animals — recover the amino acids from which we build our own proteins.
The real secret: unlocking nitrogen
Photosynthesis captures light and carbon. But nitrogen, the heart of every amino acid, demands another key — and it belongs to the invisible.
A treasure sealed in the air Nearly eight tenths of the air we breathe is nitrogen. Yet it stays locked there, so stable that almost no living being can break it — and without it, not a single amino acid could exist.
The key belongs to bacteria Only certain bacteria hold the tool that opens this door. The legumes understood it: they welcome them into fine lodges on their roots — the rhizobium —, feed them sugars, and receive the freed nitrogen in exchange. Other plants draw on what these same microbes have already left in the soil.
An alliance, at the root of life So the protein is born not of a single kingdom, but of a pact: the light captured by the plant, the nitrogen opened by the microbe. To trace proteins back to their source is to trace them to this silent understanding, beneath our feet.
At each step of the food chain, about 90% of the energy is lost — to heat, motion, cellular respiration, inedible parts. Only 10% passes on to the next level.
To produce 1 kg of beef protein, the equivalent of 7 to 16 kg of plant protein must pass through a cow. Meat does not contain proteins: it merely carries them, at the cost of a long energy detour.
The most powerful animals — gorilla, elephant, bull, horse — build their muscle mass from plants. Not an exception: the rule.
Where to find plant proteins
| Family | Examples | Density |
|---|---|---|
| Microalgae | Spirulina, chlorella | 50 – 65% |
| Seeds | Hemp, pumpkin, chia, flax | 25 – 35% |
| Legumes | Lentils, chickpeas, azuki | 20 – 25% |
| Nuts | Almonds, walnuts, cashews, pistachios | 15 – 25% |
| Whole grains | Quinoa, buckwheat, oats | 12 – 18% |
| Ferments & yeasts | Nutritional yeast, miso, tempeh | 20 – 50% |
The genius of seeds
Before being what we eat, a seed is a promise — a living being held in waiting, ready to become an entire plant. A handful of well-chosen grains carries every flavor and structure our body needs.
| Grain | Character | Use |
|---|---|---|
| Amaranth | Complete protein, gluten-free, precious micro-seeds | Porridge, popped, biscuits |
| Quinoa | Andean pseudo-grain, 14 % complete protein | Salads, bowls, sides |
| Buckwheat | Gluten-free, rich in magnesium, vascular rutin | Pancakes, kasha, granolas |
| Barley | Beta-glucan fiber (glycemic regulation) | Soups, barley risottos |
| Rice | Choose whole, semi-whole, basmati, black, red | Daily meals, plant rice puddings |
The genius of pulses
Pulses are the plant kingdom's protein reserve. Small, dry, long-keeping — yet carrying remarkable nutritional density. Paired with a grain, they form a complete essential amino acid profile.
The principle of complementarity
Two families of foods that answer each other like a key in its lock.
Key and lock To build a protein, the body needs all nine essential amino acids together. Pulses are generous in lysine and gentler in methionine; seeds and grains do the exact opposite — rich in methionine, discreet in lysine. United, they offer the full palette. This is the wisdom the world's kitchens have celebrated for millennia: dal and rice in India, chickpeas and semolina in the Maghreb, beans and corn in Mexico.
Across the day, not the minute Everything need not meet in the same meal: the body keeps a reserve pool of amino acids and composes at its own pace. A simple variety across the day — a pulse here, a seed there — already gives it the full palette.
| Pulse | Character | Use |
|---|---|---|
| Lentils (green, red, beluga) | 25 % protein, iron-rich, quick-cooking, no soaking needed | Dahls, salads, soups |
| Split peas | Naturally creamy, sweet, perfect for children | Soups, purées, dips |
| Azuki | Red Japanese pulse, sweet and remineralizing | Soups, sweet desserts, fillings |
| Beans (red, white, black) | Nourishing texture, long satiety | Chilis, stews, composed salads |
| Chickpeas | Versatile, rich in folate and fiber | Hummus, falafels, salads |
Hemp — the seed that gives itself freely
Hemp is the exception that proves the rule. Where almost every seed demands preparation — soaking, sprouting, cooking — to disarm its defenses, hemp gives itself with practically no conditions. No , no flatulent : a “clean” protein, directly assimilable. It is the plug-and-play of plant nutrition.
The active formula of hemp
Three forces gathered in one small seed.
More protein than an egg A 30 g portion delivers nearly 10 g of protein — more than an egg — and a complete protein: the nine essential amino acids, dominated by edestin and albumin, two high-quality, especially digestible proteins.
The right essential fats A rare fatty-acid profile: omega-6 (linoleic) and omega-3 (alpha-linolenic) in a balanced ratio, plus the precious GLA (gamma-linolenic) and SDA (stearidonic) that few foods provide.
A mineral density Magnesium, phosphorus, potassium, zinc and copper in remarkable amounts — the body's mineral weave, in a seed that asks only to be eaten.

Frequently asked questions
Where do proteins truly come from?
All proteins are born in the plant kingdom — plants, algae and certain microbes: they alone know how to build an amino acid from the light of the sun, the carbon of the air and the nitrogen of the earth. And nitrogen itself is unlocked by bacteria, which legumes host on their roots (the rhizobium). We, the animals, only recover these amino acids: meat does not contain proteins, it merely carries them, at the cost of a long energy detour (trophic cascade 90/10).
Which plants contain the most protein?
Microalgae like spirulina and chlorella (50 to 65 % protein), hemp, pumpkin, chia and flax seeds (25 to 35 %), ferments like miso, tempeh, nutritional yeast (20 to 50 %), legumes (lentils, chickpeas, azuki, 20 to 25 %), nuts (almonds, walnuts, cashews, 15 to 25 %), and whole grains (quinoa, buckwheat, oats, 12 to 18 %).
What is the 90/10 trophic cascade?
At each step of the food chain, about 90 % of the energy is lost — to heat, motion, cellular respiration, inedible parts. Only 10 % passes on to the next level. To produce 1 kg of beef protein, the equivalent of 7 to 16 kg of plant protein must pass through a cow. Eating plants is returning to the source.
How to compose a day with a complete protein profile?
A spoon of spirulina, a handful of hemp seeds, a portion of lentils across the day are enough for the complete profile of nine essential amino acids. No intermediary, no transformation, no loss — the body receives the bricks exactly as the plant assembled them.
