Atopic Dermatitis: Immunopathology
AD is characterized by:
- Th2 dominance: IL-4, IL-13 → filaggrin↓ → skin barrier impairment → TEWL (transepidermal water loss) ↑ → itching, dryness
- TSLP (thymic stromal lymphopoietin): produced by damaged keratinocytes → Th2 polarization → IgE production → sensitization
- Microbiome-ginger skin axis: S. aureus colonization (present in 90% of AD) → IL-36 secretion → Th2 amplification
How sugary drinks exacerbate eczema
Dysbiosis and gut-skin axis
Sugar selects pro-inflammatory gut bacteria (Bacteroides, Clostridium) → reduces Bifidobacterium/Lactobacillus → less propionate/butyrate → reduced Treg induction → systemic Th2 dominance → eczema flares.
Insulin resistance and TSLP
Chronic hyperglycemia due to sugary drinks → insulin resistance → keratinocytes produce more TSLP (insulin normally suppresses TSLP via PI3K) → Th2 initiation → AD flare.
AGEs and skin barrier
Glycation of filaggrin and loricrin by sugar-AGEs → deterioration of barrier function → increased TEWL → loss of ceramides → dry, irritable skin.
Drinks for eczema patients: comparison
| Drink | Sugar/100ml | Impact on Eczema |
|---|---|---|
| Coca-Cola | 10.6 g | Dysbiosis Th2, AGE barrier, keratinocyte NF-κB |
| Fruit juice | 9–12 g | Fructose → NLRP3 → IL-1β → flare-up |
| GIMBER | 35 g | Excessive sugar → dysbiosis, AGE despite ginger |
| INTI ginger | <4 g | NF-κB↓, Th1/Th2 balancing, prebiotic Th-reg, TSLP↓ via AMPK |
Ginger and atopic dermatitis: molecular mechanisms
- Keratinocyte NF-κB inhibition: [6]-gingerol → IL-8, CXCL1↓ → reduced neutrophil recruitment → reduced acute eczema inflammation
- Th1/Th2 balancing: gingerols stimulate IFN-γ (Th1) and reduce IL-4/IL-13 (Th2) → restore immune balance for AD
- TSLP reduction via AMPK: AMPK activation → PI3K/mTOR → reduced TSLP expression in keratinocytes → less Th2 initiation
- Microbiome prebiotic: butyrate↑ → Treg induction → Th2 suppressor → support eczema remission
- Ceramide production (Nrf2): gingerols activate Nrf2 → skin barrier ceramide genes (CerS1-6) → improved skin barrier
Frequently Asked Questions — eczema and nutrition
Can INTI cure eczema?
No — AD is a chronic autoimmune disease requiring dermatological treatment. INTI, through anti-NF-κB, Th1/Th2 balancing, and microbiome support, can contribute to reducing flare-ups and supporting remission as a supplement to medicinal treatment.
Should I dilute INTI for eczema?
Dilution (1:3 or 1:4) is recommended to reduce the initial sugar and acidity load. In sensitive individuals, undiluted INTI may cause a slight local reaction upon mouth contact. Diluted, the profile is optimal.
