The London study included nearly 2,700 middle-aged people in the U.S. and United Kingdom. The participants reported what they ate and drank for four days and completed detailed questionnaires.
Researchers found that the more sugary sodas and other sugar-sweetened beverages people drank, the higher their blood pressures tended to be.
People who reported drinking the most sugar-sweetened drinks also had the highest overall intake of calories and salt and were most likely to be obese.
The findings are reported in the journal Hypertension
Although the study appears to indicate a link between sugar and blood pressure, researchers say the findings do not prove a cause and effect.
