The Morning Takeoff

Every morning for seven years, I’ve started my day with a glass of lukewarm water with the juice of half a lemon. Not because it’s fashionable, not because an influencer recommended it, but because Marchesseau himself considered the lemon to be the king of alkalizing foods. When I mention this in consultations, nine patients out of ten look at me in disbelief: how can a fruit so acidic be alkalizing? Yet this is one of the best-documented paradoxes in nutritional biochemistry.

Bioactive molecules

The citric acid in lemon is a natural antiseptic that inhibits the development of many bacteria and yeasts in the digestive tract¹. Marchesseau considered the lemon to be the king of alkalizing foods, and biochemistry proves him right: once metabolized, the mineral residues alkalinize the internal environment². Ascorbic acid (53 mg/100 g) regenerates hepatic glutathione and supports immunity³. The limonene in the zest activates phase I detoxification at the level of cytochrome P450⁴.

Citric acid is the central compound in this juice. A natural antiseptic, it inhibits the development of many bacteria and yeasts in the digestive tract. This juice is recommended for intestinal fermentation, bloating, mild food poisoning, and as general digestive support. Before the invention of antibiotics, diluted lemon juice was used as a makeshift surgical antiseptic, and British sailors (the “limeys”) carried lemons to prevent scurvy during sea voyages. That speaks to the power of this modest fruit.

Lemon is the most concentrated source of citric acid (5-8% by weight), a natural mineral chelator that increases non-heme iron absorption by 200%²: 103-108). Vitamin C (53 mg/100g) is a water-soluble antioxidant essential for collagen synthesis. Limonene, the dominant monoterpene in the zest’s essential oil, activates phase I and II hepatic detoxification enzymes.

The lemon is an antiseptic, a powerful alkalinizer in vital individuals, and a major source of vitamin C and bioflavonoids. Apparent paradox: despite its acidic taste, lemon is an alkaline food. The natural citric acid it contains transforms into carbon dioxide (exhaled) and releases its minerals which alkalinize the blood. One liter of lemon juice provides approximately 1 gram of calcium and 0.30 g of phosphorus. The manganese in lemon oversees proper gonad function. Caution: this alkalinization only works in people with sufficient digestive power. Thin, cold-sensitive people who experience tooth sensitivity and chills when consuming lemon are those whose metabolism doesn’t transform it correctly; they should avoid it. A few drops are enough to slow the oxidation of your juices and enhance the absorption of plant iron. Indications: wounds, gum bleeding, gastro-duodenal ulcers, dyspepsia, hyperchlorhydria (paradoxically), remineralization cure. Always start gently: one quarter lemon, then increase gradually.

The lemon is antiseptic, alkalizing in vital individuals, rich in vitamin C and bioflavonoids. A few drops are enough to slow the oxidation of your juices and enhance plant iron absorption. It is considered a universal medicine.

Preparation with a juice extractor

Ingredients:

• 3 organic carrots
• 2 peeled oranges
• 1 piece of ginger (3 cm)
• 1 piece of fresh turmeric (2 cm)
• 1 peeled lemon

Horseradish is probably the most powerful vegetable in the entire juice pharmacopeia. Half a teaspoon of grated horseradish is enough to clear the most stubborn sinuses. This juice is recommended specifically for sinusitis, bronchitis, and chronic nasal congestion. The principle: horseradish isothiocyanates (the same molecules in mustard) violently stimulate respiratory mucous membranes, causing abundant secretion that evacuates stagnant mucus. Combined with lemon (vitamin C + bioflavonoids), it’s the most effective anti-congestion duo in European herbalism. Caution: pure horseradish juice is VERY powerful. Always dilute it in carrot or apple juice, and never exceed 30 ml per dose.

What I personally think

In Martinique, the old-timers have their ‘take-off’ each morning: a ti-punch at dawn before heading to the fields. Agricultural rum, freshly pressed lime, cane sugar. My take-off is pure lemon from the extractor, without the rum. The other story I owe to lemon is from Indonesia. When you wipe out surfing and coral shreds your skin, locals immediately squeeze lime juice on the wound. It’s not sadism: the acidity of lime (pH 2-3) kills the live coral cells embedded in your flesh. If you don’t do it, the coral continues to grow under your skin and the wound becomes infected for weeks. Citric acid disinfects and vitamin C accelerates healing. Indonesian fishermen and surfers have known this for generations.

My recommended juice extractor

For this recipe, I use the Hurom H310A. Cold pressing preserves all the enzymes, vitamins, and phytonutrients that the heat of a centrifuge would destroy.
