Coca-Cola 350ml
350ml was consumed from a 500ml bottle.
After consuming regular Coca-Cola, blood sugar levels rose sharply, reaching a peak (approximately 200mg/dL) after 30-40 minutes. Then, from around 60 minutes, it gradually decreased, returning to nearly baseline levels after 120 minutes.
- Characteristics:
- Rapid blood sugar increase
- High peak value (approximately 200mg/dL)
- Relatively rapid decline

Coca-Cola Zero 350ml
350ml was consumed from a 500ml bottle.
Since Coca-Cola Zero uses artificial sweeteners, blood sugar levels remained almost stable after consumption. While there were slight fluctuations, no significant impact was observed.
Characteristics:
- Almost no effect on blood sugar levels

Blood Sugar Comparison_1
The graph below compares the blood sugar changes between Coca-Cola and Coca-Cola Zero.
From this graph, we can see that while Coca-Cola causes a sharp rise in blood sugar levels, Coca-Cola Zero has no impact on blood sugar levels.

Summary
- Coca-Cola Zero is suitable for those who want to avoid rapid blood sugar spikes
- Regular Coca-Cola appears to be effective when quick energy replenishment is needed, such as during exercise
