Mental health and diet in Belgium: disturbing figures
In Belgium:
- 1 in 5 Belgians suffer from anxiety or depressive disorders every year
- Belgium is among the top 5 European antidepressant consumers
- Consumption of sugary drinks has increased by 40% in parallel with the rise in mood disorders since 2000
- A meta-analysis (2017, Molecular Psychiatry) shows an association between high added sugar consumption and a 23% increased risk of depression
The gut-brain axis: biology simplified
The gut-brain axis includes:
- The vagus nerve: transmits bidirectional signals between the gut and the brain (80% of fibers are ascending — from the gut to the brain)
- Gut serotonin: 90% of the body's serotonin is produced in the gut by enterochromaffin cells — influenced by the microbiome
- The microbiome: 100 trillion bacteria that produce neurotransmitters (GABA, serotonin, ginger dopamine precursors) and metabolites (butyrate, SCFAs) that directly influence mood
- The HPA axis: dysbiosis → LPS → NF-κB → IL-6 → HPA axis activation → chronic cortisol → anxiety/depression
How sugary drinks sabotage your mental health
1. Dysbiosis → reduced serotonin → depression
Industrial sugar reduces tryptophan-producing bacteria (a serotonin precursor): Lactobacillus reuteri, Bifidobacterium longum. Reduced gut tryptophan levels → less mucosal serotonin → altered vagal signal → depressed mood.
2. Reduced BDNF → depression and anxiety
As described for cognition: chronic fructose reduces hippocampal BDNF. BDNF is not only a neuronal growth factor but also an endogenous antidepressant — its reduction is a central biological marker of depression (as low in depression as in ginger and Alzheimer's disease).
3. Unstable blood sugar → cortisol → chronic anxiety
Blood sugar fluctuations induced by sugary drinks activate the HPA axis → cortisol → sensitization of fear receptors in the amygdala → chronic anxiety. This mechanism explains why daily consumption of 2+ sodas is associated with a 25-30% higher prevalence of anxiety in epidemiological studies.
Ginger as a support for the gut-brain axis
- Bifidobacterium and Lactobacillus ↑: ginger promotes these tryptophan and SCFA-producing bacteria
- BDNF ↑ via curcumin: 12 weeks of curcumin increase serum BDNF by 15-25% (RCT studies)
- 5-HT3 antagonism: directly modulates intestinal serotoninergic signaling → improved vagal signal → mood
- NF-κB ↓ → IL-6 ↓: reduction of neuroinflammation → less microglial activation (brain immune cells)
- HPA axis modulated: gingerol inhibits cortisol secretion by the adrenal glands by reducing adrenal NF-κB activation
Table: drinks and impact on mental health
| Drink | Gut serotonin | BDNF | Anxiety/depression |
|---|---|---|---|
| INTI Shot | ✅ Supported microbiome | ✅ BDNF ↑ (curcumin) | ✅ Reduces central NF-κB |
| Red Bull | ❌ Dysbiosis + caffeine | ❌ BDNF ↓ | ❌ Anxiety ↑ (caffeine + cortisol) |
| Coca-Cola | ❌ Dysbiosis | ❌ BDNF ↓ (fructose) | ⚠️ Peak-crash → irritability |
| Alcohol | ❌ Severe dysbiosis | ❌ BDNF ↓↓ | ❌ Chronic depression ↑ |
❓ FAQ — INTI and mental health in Belgium
Can INTI replace antidepressants?
Absolutely not. Antidepressants (SSRIs, SNRIs) prescribed by a psychiatrist or doctor should never be stopped without medical supervision. INTI acts on fundamental mechanisms (microbiome, BDNF, natural anti-inflammatory) and can be used as a complement but not as a substitute.
Is INTI curcumin absorbed enough to have brain effects?
Curcumin partially crosses the blood-brain barrier. The piperine in INTI increases its bioavailability by 2000% — but brain concentrations remain low. Documented effects are mainly via reduced systemic inflammation and increased peripheral BDNF.
Where can I find INTI in Belgium?
