Daily sugary drinks linked to higher stomach-cancer risk
Researchers studied more than 112,000 people to see whether sugary drinks were linked to stomach cancer.
They found that people who drank at least one sugary drink each day had a higher risk.
The risk was about 2.45 times higher than for people who did not drink these beverages.
Women in the study had an even higher reported risk, while men had about twice the risk.
Sugary drinks include regular soda, cola and some sports drinks with added sugar.
Too much sugar may contribute to weight gain, insulin resistance and inflammation.
These changes might be connected to cancer risk.
However, the study only found an association, not proof that sugary drinks cause cancer.
More research is needed to understand whether sugar itself is responsible.
A study of more than 112,000 people linked daily sugary-drink consumption to stomach cancer.
People drinking at least one sugary soft drink daily had 2.45 times the risk of stomach cancer.
The reported risk was about three times higher among women and about twice as high among men.
Sugary drinks include regular soft drinks, colas and sports drinks with added sugars.
Researchers stressed that the observational study does not prove sugary drinks cause cancer.
- Who

- When
- The article does not specify when the study was conducted.
- Why
- Researchers examined whether sugary-drink consumption was associated with stomach-cancer risk, but said the cause of the association remains uncertain.
Evidence of a possible link
Caution about causation
Meaning of the findings
Evidence of a possible link
Researchers reported that daily sugary-drink consumption was associated with a substantially higher risk of stomach cancer, potentially involving weight gain, insulin resistance, inflammation and other metabolic processes.
Caution about causation
The researchers said the findings do not prove that sugary drinks cause cancer because the study was observational, relied partly on self-reported information and had incomplete data in some areas.
Role of sugar
Evidence of a possible link
Frequent high sugar intake may contribute to biological changes that could be connected to stomach-cancer risk.
Caution about causation
Further studies are needed to determine whether sugar itself is driving the increased risk or whether other factors explain the association.
