According to ANSES, 80% Have Undefined Brains
- Undernutrition often conjures images of a gaunt frame or an empty stomach.
- The answer, for many, appears to be no, and our brains are suffering the consequences.
- modern diets are frequently characterized by ultra-processed foods, high in calories but lacking essential nutrients.
Brain Drain: Are You Among the 80% Suffering From Nutritional Deficiency?

Undernutrition often conjures images of a gaunt frame or an empty stomach. However, a more insidious form of deficiency exists, one that directly impacts the brain. Shockingly, estimates, including those relayed by the National Agency for Food Safety (ANSES), suggest that this affects eight out of ten people.
We may be eating, but are we eating well? The answer, for many, appears to be no, and our brains are suffering the consequences.
The Paradox: A Full Plate, An Empty Brain
modern diets are frequently characterized by ultra-processed foods, high in calories but lacking essential nutrients. This creates a situation where the stomach may be full, but the brain remains undernourished.
Dr. Guillaume Fonde, a psychiatrist and psycho-nutrition researcher, has raised concerns about this issue. He states that “The majority of people with depressive disorders have an essential micronutrient deficiency, including vitamin D.”
Numerous studies, both in France and internationally, support this assertion. An imbalanced diet can disrupt the production of neurotransmitters, the chemical messengers responsible for regulating emotions, attention, and memory.
Decoding the signals: Symptoms of Brain Undernutrition
Unlike conventional undernutrition, brain undernutrition is often invisible to the naked eye. However, its effects are palpable.
These symptoms can be indicative of a deficiency in omega-3 fatty acids, iron, B vitamins, vitamin D, vitamin C, or magnesium – all crucial for optimal brain function.
The Prevalence of ‘Horny Brain’: Why 80% Are Affected
Modern Lifestyle: A Contributing Factor
The statistic is alarming: approximately 80% of individuals may have brains lacking essential nutrients. This figure is based on compiled data from ANSES, INSERM (French National Institute of Health and Medical Research), and various studies examining nutrition and mental health in France.
How has this situation arisen?
Key Nutrients for Brain Health
Brain undernutrition is not an unavoidable fate. Incorporating specific nutritional elements into your diet can make a significant difference:
- omega-3 DHA: Enhances memory, attention span, and mood. Found in fatty fish (salmon, sardines, mackerel) and certain oils (flaxseed, rapeseed, walnut).
- Vitamin D: Vital for the nervous system and linked to depression prevention. Synthesized through sun exposure; supplementation may be necessary during winter or in cases of deficiency.
- B Vitamins (B6, B9, B12): Involved in the production of dopamine and serotonin, the “happiness hormones.” Present in eggs, legumes, dairy products, and green vegetables.
- Magnesium: A natural anti-stress agent that promotes brain relaxation. Found in oilseeds (almonds, walnuts), dark chocolate, seafood, and whole grains.
- Antioxidants: Protect neurons from oxidative stress.Abundant in red fruits, green tea, turmeric, and colorful vegetables.
the Plate as a Starting Point
recent research in neuro-nutrition confirms the direct influence of diet on mental well-being. A 2015 study published in The Lancet Psychiatry suggests that improved nutrition could potentially prevent certain psychiatric disorders. While healthy eating is not a panacea for all mental health issues, it provides a crucial foundation.
The assertion that 80% of people suffer from brain undernutrition is not an exaggeration.It is a documented reality, and, importantly, a reversible one.
NOTE:
An ANSES study indicates that nearly 80% of weight-loss diets observed in adult women lead to iron deficiency. This mineral is essential for optimal brain function,facilitating oxygen transport and neurotransmitter production. Iron deficiency can result in fatigue,memory lapses,and low morale.
