"Zero" or "Light" Sodas: The Hidden Problem
In Belgium, consumption of "light" or "zero" drinks has increased by 40% since 2010, driven by the belief that they are healthy. But recent scientific data challenge this conviction:
- Aspartame (Coca-Cola Zero): classified as "possibly carcinogenic" (Group 2B, IARC 2023) — a disputed but concerning evaluation. Documented microbiome disruption.
- Acesulfame K (Coca-Cola Zero, Sprite Zero): alters the composition of the gut microbiome, reduces bacterial diversity.
- Sucralose (Pepsi Max): formation of chloropropanols during heating; microbiome disruption at high doses.
- Stevioside (7Up Free): the best tolerated of all, but effects on the microbiome are still being studied.
Mechanisms of Microbiome Disruption by Sweeteners
Suez et al. (Cell 2022, n=120) showed that artificial sweeteners alter post-meal glycemic response in a personalized way via the microbiome:
- Aspartame and sucralose alter the composition of Bacteroides and Clostridiales.
- These changes alter the production of microbial metabolites (short-chain fatty acids).
- Result: increased post-meal glycemic response in some subjects → paradoxically, light sodas can increase post-meal blood sugar.
- The brain "sees" sweetness but doesn't get the expected calories → maintains addiction to sweet taste.

| Drink | Sugar | Sweeteners | Microbiome | Health Benefits |
|---|---|---|---|---|
| Coca-Cola Classic | 10.6g/100ml | No | Negative (sugar) | None |
| Coca-Cola Zero | 0g | Aspartame + Ace-K | Negative (sweeteners) | None |
| Pepsi Max | 0g | Sucralose + Ace-K | Negative (sweeteners) | None |
| INTI Ginger Elixir | <4g natural | None | Positive (Akkermansia ↑) | NF-κB ↓, AMPK ↑ |
INTI and the Microbiome: The Evidence
Unlike sweeteners that disrupt the microbiome, ginger has shown positive effects:
- Increase in Akkermansia muciniphila (gut barrier protective bacteria) — rodent study, Li et al., 2018
- Reduction of pro-inflammatory Clostridiales.
- Inhibition of NLRP3 inflammasome → reduces gut permeability.
- Increase in short-chain fatty acids (SCFAs) via fermentation of fresh ginger polysaccharides.
FAQ — Light Sodas vs. INTI
Is Coca-Cola Zero frankly dangerous? Studies indicate microbiome disruptions and an IARC Group 2B classification (aspartame). For occasional consumption, the risk is low. For daily consumption, the cumulative effects on the microbiome are concerning.
Is stevia better than aspartame? Yes — stevioside seems to have a more favorable profile than aspartame. INTI uses no sweeteners: neither stevia, nor aspartame, nor any other. The residual sugar (<4g) is naturally present in fresh ginger.
Can INTI give you the "soda" taste? INTI + sparkling water = a "sparkling ginger drink" that satisfies the craving for a sparkling beverage without sugar or sweeteners. It's the closest alternative to soda for palates that are looking for one.
