For many Filipinos, opening a cold can of Coca-Cola is almost second nature — a quick boost during lunch, a reward after a long day, or a staple at family gatherings.
But behind the familiar fizz, health experts are raising renewed concerns about what regular soda drinking does to the body.
A sugar hit — fast and intense
The high sugar content of soda is hardly news. What’s drawing attention now is how quickly it affects the body.
Studies show that within the first hour of drinking a can of regular Coke, blood sugar levels spike sharply, triggering what many experience as a sudden burst of energy.
Because Coca-Cola also contains caffeine, frequent consumption can create a mild form of dependence. According to The Telegraph, some habitual soda drinkers even need to cut back gradually to avoid headaches, fatigue, or irritability linked to caffeine and sugar withdrawal.
What recent studies are finding
New research is strengthening the link between sugar-sweetened beverages and chronic disease.
A major study published in Nature Medicine connected millions of global cases of Type 2 diabetes and cardiovascular disease to sugary drinks. Another study by Swedish researchers went further, directly criticizing the sugar-drink industry for its role in rising heart disease cases.
Taken together, the findings point to increased risks of fatty liver disease, diabetes, and heart problems among regular soda drinkers — conditions that often develop silently over years.
Misleading labels, experts say
In the United Kingdom, nutrition experts are also questioning how sugary drinks are labeled. Coca-Cola reportedly received three green “traffic light” labels — a system meant to guide consumers toward healthier choices.
“Coke is just through the roof [for sugar],” specialist registered dietitian Nichola Ludlam-Raine told The Telegraph. “In my opinion, it shouldn’t be allowed to be sold.”
The environmental cost of a can
Health isn’t the only issue. Coca-Cola remains the world’s biggest producer of branded plastic waste. While the company has announced initiatives to reduce plastic use and improve recycling, environmental groups say these efforts still fall short of what’s needed.
What you can do
Researchers continue to examine the long-term effects of soda consumption, but health experts agree on one thing: cutting back helps. Reducing sugary drinks — even gradually — can lower health risks over time.
Simple swaps, such as sparkling water or lightly flavored fizzy drinks with no added sugar, offer a way to keep the bubbles without the health baggage.
That familiar can of Coke may feel harmless in the moment. But as the evidence grows, experts say it’s worth rethinking how often it finds its way into your daily routine.
