The Drink Linked to Cancer Risk: One Glass a Day May Raise the Danger by 90%

In recent years, health experts have raised growing concerns about certain everyday beverages that may significantly increase the risk of cancer when consumed regularly. Alarmingly, research suggests that drinking just one glass per day of this type of beverage could raise the risk of cancer by up to 90%, according to observational studies.

While the drink is widely consumed and often perceived as harmless — or even enjoyable — scientists warn that its long-term effects on the body may be far more serious than previously thought.

What Is This High-Risk Beverage?

Medical researchers point primarily to sugar-sweetened beverages, including:

• Soft drinks

• Sweetened fruit juices

• Bubble tea and flavored milk teas

• Energy drinks

These beverages are high in refined sugars, especially fructose, which can disrupt normal cellular metabolism.

Why Can Sugary Drinks Promote Cancer Growth?

Cancer cells require large amounts of energy to grow and multiply. Excessive sugar intake may:

• Increase insulin and insulin-like growth factors

• Promote chronic inflammation

• Create an environment that favors abnormal cell growth

• Contribute to obesity, a well-known cancer risk factor

Several large population studies have found strong associations between high consumption of sugary beverages and increased risks of cancers such as breast, colorectal, liver, and pancreatic cancer.

What Does the Science Say?

A major epidemiological study published in international medical journals found that people who consumed one or more sugar-sweetened drinks daily had a significantly higher overall cancer risk compared to those who rarely consumed them. Some cancer types showed risk increases approaching 90%, particularly when combined with sedentary lifestyles and poor dietary habits.

Importantly, researchers emphasize that these studies show association, not direct causation, but the consistency of findings across populations is concerning.

Warning Signs and Who Should Be Most Careful

People at higher risk include:

• Those with obesity or metabolic syndrome

• Individuals with a family history of cancer

• People with fatty liver disease or insulin resistance

• Those who consume sugary drinks daily over many years

Doctors stress that cutting back early can substantially reduce long-term risk.

Healthier Alternatives Doctors Recommend

To protect long-term health, experts advise replacing sugary beverages with:

• Plain water

• Unsweetened tea

• Black coffee without sugar

• Infused water with natural fruit slices

Reducing sugar intake not only lowers cancer risk but also improves heart health, liver function, and metabolic balance.

A Final Warning

Cancer does not develop overnight. It is often the result of years of cumulative lifestyle choices. While enjoying an occasional sweet drink may not be dangerous, daily consumption could quietly push the body toward disease.

Doctors urge the public to rethink their drink choices — because what seems refreshing today may carry serious consequences tomorrow.
