Acute immunosuppression by sugar: the fundamental research
In 1973, Sanchez et al. (American Journal of Clinical Nutrition) showed that consuming 100g of sugar (equivalent to a large sugary soft drink) reduced the phagocytic capacity of neutrophils by 40% for 1-5 hours after consumption. This fundamental research has since been confirmed and expanded.
Biochemical mechanisms: sugar → immunosuppression
1. Glucose/vitamin C competition for GLUT1
Glucose and vitamin C (oxidized ascorbic acid → dehydroascorbate) share the same cellular transporter GLUT1. In post-soda hyperglycemia, glucose massively enters neutrophils, displacing vitamin C. Neutrophils require high intracellular vitamin C levels for phagocytic activity (production of bactericidal peroxides). Less vitamin C in the neutrophil = reduced phagocytosis.
2. Hyperinsulinemia → cortisol-stress-surrenales-burnout">ginger cortisol → immunosuppression
The post-soda insulin peak triggers a cortisol counter-regulation. Cortisol is a powerful immunosuppressant: it reduces the production of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6), inhibits lymphocyte proliferation, and lowers NK cell activity. A daily soda-insulin-cortisol cycle maintains relative chronic immunosuppression.
3. Zinc depletion via hyperinsulinemia
Insulin facilitates intracellular zinc transport. Chronic hyperinsulinemia increases cellular zinc uptake, reducing the circulating zinc available for immunity. Zinc is indispensable for T-lymphocyte maturation, antibody production, and NK cell activity.

FAQ — INTI and immunity Belgium
Does one soda per day really weaken the immune system?
Yes, temporarily (5h after consumption) according to neutrophil studies. Chronically, the cortisol/zinc effect accumulates. Occasional soda is rarely problematic; daily has a real impact.
Is INTI more effective than vitamin C for immunity?
Different, not necessarily more effective. INTI offers anti-NF-κB mechanisms, direct antimicrobial and antiviral properties that vitamin C does not have. Both are complementary.
Does INTI help people on immunosuppressants?
ginger shot without sugar can interact with certain immunosuppressants (cyclosporine). Consult your doctor if you are transplanted or on immunosuppressive treatment.
