Introduction — Why Parkinson’s may start in your gut, not your brain Parkinson’s disease is traditionally described as a brain disorder driven by the progressive loss of dopamine-producing neurons. This is what leads to the hallmark symptoms people recognize—tremors, stiffness, slowed movement. But this definition is now outdated. A growing body of research suggests that […]

Introduction — A simple food, but biologically exceptional Eggs occupy a unique place in the human diet: universal, accessible, nutrient-dense — and yet repeatedly challenged over the decades. They have been celebrated as a “superfood”, then questioned because of their cholesterol content, before being progressively reappraised as research learned to distinguish dietary cholesterol from blood […]

Introduction — Inflammation isn’t the problem. Chronicity is. Inflammation is an essential biological response for survival. It enables the body to react to an insult, repair tissues, contain infection, or heal a lesion. In its acute form, it is rapid, targeted, and then switches off once the threat has been controlled. So the issue is […]

Introduction For centuries, food processing had a straightforward purpose: to make foods safer, easier to digest and more stable (through cooking, fermentation, drying and preservation). This kind of processing alters food, but generally preserves an identifiable food matrix — fibres, structure, texture, and digestion kinetics. Modern industrial eating introduced a clear break: ultra-processed foods (UPFs) […]

Introduction — Inflammation isn’t a disease: it’s a biological language Inflammation is one of life’s most fundamental biological mechanisms. It is an essential adaptive response to injury, infection and tissue repair. Without acute inflammation, there is no wound healing, no effective immune defence, and ultimately no survival [1]. Over the past few decades, ageing biology […]

Introduction — Ageing isn’t an age; it’s a biological trajectory For decades, ageing was approached as a mechanical consequence of time: the mere accumulation of years leading to a progressive, inevitable decline in biological function. This chronological reading, inherited from descriptive twentieth-century medicine, profoundly shaped medical, nutritional and preventive frameworks. Contemporary advances in cellular biology, […]

Introduction — From corrective nutrition to the biology of information For much of the twentieth century, nutrition was approached through an essentially corrective lens. The goal was to prevent deficiencies, provide sufficient calories, and secure the vitamin and mineral intakes required for survival and the body’s minimal functioning. Historically, this approach was indispensable. It helped […]

Introduction — Cellular Nutrition: the true level at which life is regulated Cellular Nutrition is sometimes presented as a forward-looking or avant-garde approach. This perception is misleading. It suggests that Cellular Nutrition is a recent conceptual construct, whereas it is in fact the nutritional translation of a scientific shift that has already been firmly established […]

Why you’re gaining weight despite eating healthy? When the issue is no longer diet, but the cellular response. Introduction — “I eat well, yet I’m gaining weight” This is one of the most common complaints in clinical practice: “I eat healthily, I avoid excesses, I pay attention to food quality… and yet I’m gaining weight.” […]

Introduction — A necessary scientific clarification The word “detox” has become mainstream, almost unquestioned. It is generally used to suggest that the body becomes “loaded” with toxins and that we should periodically intervene to remove them through juice cleanses, restrictive programmes, or so-called “draining” supplements. The idea is appealing because it is simple. It is […]

Abstract Oxidative stress is often portrayed as a purely chemical aggression against the cell, to be neutralised by exogenous antioxidants. This simplified view, widely disseminated in nutritional and marketing narratives, does not withstand scrutiny in contemporary cell biology. This article examines the physiological role of reactive oxygen species (ROS), the regulatory nature of redox signalling, […]

By Dr. Espinasse Abstract Despite the widespread dissemination of nutritional guidelines, the prevalence of chronic fatigue, metabolic imbalance, low-grade inflammation and accelerated functional ageing continues to rise. This paradox highlights a structural limitation of intake-based nutritional models: nutrient availability does not guarantee bioavailability, nor effective cellular utilisation. This article reviews recent evidence from cell biology, […]

By Dr. Espinasse Introduction — Why ageing must be reconsidered at the cellular level When I read Lifespan: Why We Age – and Why We Don’t Have To by David A. Sinclair, I saw far more than a book about longevity. I recognised an ambitious and structured attempt to biologically redefine ageing, moving it away […]

Introduction — Longevity is not an age; it is biology Modern longevity is no longer simply about living longer. The scientific goal is now clear: preserving, for as long as possible, energy, mental clarity, muscle mass, immune resilience, and independence — in other words, optimising functional longevity. This perspective is now shared by leading academic […]

Introduction — Micronutrition: Between Simplistic Promises and Biological Complexity Micronutrition has established itself as a modern response to very concrete health concerns: persistent fatigue, stress, digestive disorders, weakened immunity, glycaemic imbalances, weight management difficulties, or hormonal discomfort. Its success is built on an intuitive and scientifically sound idea: micronutrients are essential to the functioning of […]

Introduction — Detox: modern myths, widespread misconceptions, and biological reality Detox is everywhere. Juice cleanses, detox programmes, short-term fasts, “miracle” supplements, promises of rapid purification. In the collective imagination, detoxification is presented as a necessary reset — a temporary intervention designed to “cleanse” a body assumed to be overloaded with toxins. This narrative is appealing […]

Introduction — The brain, long seen as an organ “apart” The brain consumes close to 20% of the body’s total energy, even though it represents only around 2% of body weight. This intense metabolic activity continuously generates cellular waste, metabolites, oxidised proteins, and inflammatory by-products that must be cleared with precision in order to preserve […]

Food supplements now play a central role in health, prevention, and wellness strategies. Fatigue, stress, immunity, digestion, sleep, skin, metabolism — for every concern, there is a wide range of solutions on the market, often presented as simple, natural, and effective. Yet both clinical practice and user experience point to a consistent reality: food supplements […]

Introduction — From corrective (micro)nutrition to informational nutrition For a long time, (micro)nutrition was approached essentially from a corrective perspective: addressing deficiencies, providing vitamins, supplementing identified shortfalls. This approach, historically necessary, made it possible to prevent major deficiency-related diseases. However, it now shows its limitations when faced with modern challenges: chronic fatigue, low-grade inflammation, metabolic […]
