Why After 40, Our Brain Needs Special Nutrition
Turning 40 isn’t just about a number. It’s a biological milestone where several factors converge, making our mental balance more vulnerable and our diet more crucial than ever.
The Hormonal Revolution: Estrogen and Serotonin
Estrogen plays a key role in regulating serotonin, often called the « happiness hormone. » Perimenopause and menopause, by causing estrogen levels to drop, can directly impact our mood. “According to Dr. Sarah Gottfried, a specialist in hormonal health, ‘What you eat becomes the raw material for your hormones. Without the right nutrients, the production of neurotransmitters like serotonin is compromised.’” A diet rich in serotonin precursors therefore becomes an essential pillar.
Silent Inflammation: The Fire Ravaging Your Mood
Chronic low-grade inflammation is an invisible enemy of mental health. It can damage nerve cells and disrupt brain communication. After 40, metabolism slows down and oxidative stress accumulates, promoting this inflammation.
Testimonial: “I constantly felt foggy and irritable. I didn’t understand why,’ recalls Sophie, 52. ‘My naturopath talked about inflammation. Changing my diet was a return to light.”

The Second Brain: The Gut-Brain Axis
Your gut houses millions of neurons and produces nearly 90% of your body’s serotonin. This ecosystem, the microbiome, communicates directly with the brain via the vagus nerve. An imbalanced gut flora (dysbiosis) can therefore generate anxiety, mental fatigue, or low mood. Nourishing your microbiome is nourishing your brain.
The 7 Star Food Families for Your Mental Balance
Our team of experts has identified these non-negotiable food groups for a winning food and mood strategy.
Omega-3s (EPA and DHA): The Brain’s Builders
Omega-3 fatty acids, particularly EPA and DHA, are the main structural components of our brain. They have powerful anti-inflammatory properties and are crucial for the fluidity of neuronal membranes.
-
Where to find them?: Fatty fish (wild salmon, mackerel, sardines, herring), ground flax seeds, chia seeds, walnuts.
-
Scientific Evidence: A study published in the Journal of Epidemiology & Community Health showed that high consumption of fatty fish was associated with a lower risk of depression.
Testimonial: “Adding sardines to my lunch twice a week was a game-changer. My ability to concentrate improved greatly. “

Probiotics and Prebiotics: Feed Your Inner Army
Probiotics (good bacteria) and prebiotics (fibers that feed them) are essential for maintaining a healthy and diverse microbiome, ensuring optimal production of neurotransmitters.
-
Where to find them?: Probiotics: plain yogurt with live cultures, kefir, raw sauerkraut, kimchi, kombucha. Prebiotics: garlic, onion, leek, asparagus, bananas (preferably green), oats.
-
Scientific Evidence: *“A 2020 meta-analysis concluded that probiotic supplementation could significantly reduce symptoms of depression and anxiety.”*
Testimonial: “My digestion was slow and my mood was low. Starting my day with a kefir and banana smoothie regulated everything, in my body and in my mind.”

Antioxidants: Shields Against Oxidative Stress
Antioxidants fight free radicals that damage brain cells and accelerate cognitive aging. Berries, in particular, are concentrated antioxidant powerhouses.
-
Where to find them?: Berries (blueberries, raspberries, blackberries), matcha green tea, dark chocolate (>70% cocoa), artichoke, turmeric.
-
Scientific Evidence: “Dr. Uma Naidoo, a nutritional psychiatrist, states that ‘the polyphenols in berries cross the blood-brain barrier and protect the brain from degeneration.’”
B Vitamins: The Sparks of Nervous Energy
B vitamins (B6, B9 folate, B12) are essential cofactors for the production of all neurotransmitters, including serotonin, dopamine, and GABA. The need for B12, in particular, can increase with age.
-
Where to find them?: Leafy green vegetables (spinach, kale), legumes (lentils), avocado, eggs, nutritional yeast, meat and fish (B12).
-
Scientific Evidence: “A deficiency in vitamin B12 is strongly correlated with fatigue, brain fog, and mood disorders, especially in mature women.”
Magnesium: The Premier Anti-Stress Mineral
Magnesium is involved in over 300 biochemical reactions, including the regulation of the stress response and muscle and nerve relaxation. Chronic stress depletes our magnesium stores, creating a vicious cycle.
-
Where to find them?: Dark chocolate, almonds, cashews, pumpkin seeds, spinach, bananas.
Testimonial: “I was snacking on chocolate without realizing my body was craving magnesium! Now, I consciously have a few squares of dark chocolate and my evening anxiety has disappeared.’ – Marianne, 51”

FAQ ( Frequently Asked Questions)
Q1: How long does it take to see the effects of a « food and mood » diet on my mood?
A: Some effects, like more stable blood sugar, can be felt within a few days. For deeper changes at the microbiome and inflammation level, allow several weeks, even 2 to 3 months of consistency.
Q2: Should I take supplements for my mental health after 40?
A: Diet should always come first. However, certain supplements like Vitamin D, Omega-3s (if you don’t eat fish), or Magnesium can be beneficial. It is crucial to consult a healthcare professional (doctor, nutritionist) to get an assessment and tailor supplementation to your specific needs.
Q3: What are the signs that I should see a doctor rather than just changing my diet?
A: If you experience profound and persistent sadness, loss of interest in activities you once enjoyed, significant sleep or appetite disturbances, or dark thoughts, it is imperative to consult a doctor or psychologist. Diet is tremendous support, but it does not replace a medical diagnosis and accompaniment when necessary.
Q4: I’m very busy. How can I adopt this diet without spending hours on it?
A: Prioritize simplicity: one-pan meals, batch-cooking vegetables and quinoa for the week, canned sardines and legumes (without additives) for quick fixes. A quick green smoothie can be an excellent way to load up on nutrients.
