Do sugary drinks in childhood lead to high blood pressure in adulthood?
In a study that followed 25,749 people for up to 25 years, those who drank two or more servings of sugar-sweetened beverages a day had a 52% higher risk of developing high blood pressure as adults. Fruit juice was linked to higher risk too, but whole fruit was not.
Researchers used the Growing Up Today Study, which enrolled participants at a mean age of 12 and followed them to a mean age of 36. Diet was not measured once and forgotten. Participants filled out validated food frequency questionnaires every one to four years, so the researchers could see what people actually drank across the years when eating habits are still forming.
That long window matters, because high blood pressure, or hypertension, rarely shows up overnight. It builds over decades. Catching the dietary pattern that feeds it while someone is still a teenager gives you a much better shot at preventing it than waiting for a high reading in middle age.
What the data show
The clearest signal came from sugar-sweetened beverages. People drinking two or more servings a day carried a 52% higher risk of hypertension compared with people who drank less than three servings a week. That is not a small bump.
Fruit juice landed in the same direction. At 1.5 or more servings a day, juice was linked to a 35% higher risk of hypertension compared with less than one serving a week. Meanwhile, total fructose intake showed no association, and neither did whole fruit. So the sugar molecule itself was not the villain. What mattered was the package it arrived in.
The most useful finding was what happened when people traded one drink for another. Replacing one daily serving of a sugary drink with whole fruit was linked to a 22% lower risk of hypertension, with milk a 13% lower risk, and with water a 9% lower risk. Replacing fruit juice with whole fruit was linked to a 19% lower risk.
Dr. Kumar’s Take
I find the fruit juice result the most important part of this paper, because juice still has a health halo it has not earned. Parents who would never hand a child a can of soda will pour a large glass of orange juice and feel good about it. This study suggests the body does not draw that distinction as sharply as the label does.
The reason, I suspect, comes down to what is missing. Whole fruit delivers the same sugars wrapped in fiber and inside intact plant cells, so it hits your bloodstream slowly and fills you up. Juice strips all of that away and leaves a fast dose of liquid sugar. That total fructose intake showed no link at all fits this reading. Fructose from an apple behaves differently than fructose from a bottle.
This is observational research, so it can show a pattern but cannot prove that sugary drinks caused the high blood pressure. People who drink a lot of soda tend to differ in other ways too. Still, the size of the group, the length of the follow-up, and the repeated diet measurements make this stronger than most nutrition studies.
How strong is the evidence?
Prospective cohort studies like this one sit near the top of what is realistic for diet research. You cannot randomize thousands of children to drink soda for 25 years, so this design is close to the best available. Following 25,749 people from a mean age of 12 into their thirties, with diet recorded repeatedly rather than recalled once, avoids a lot of the memory error that weakens weaker nutrition papers.
The limits are real, though. Diet was self-reported, and people underreport things they suspect are unhealthy. The substitution analysis is a statistical model, not an experiment, so the swap figures describe what the data predict rather than what a trial proved. And participants in this cohort are not a perfect mirror of the general population.
Practical Takeaways
- If your household drinks two or more sugary drinks a day, that is the single pattern this study links most strongly to future high blood pressure, so cutting back there gives you the biggest return.
- Treat fruit juice like a sugary drink rather than a serving of fruit. Intake of 1.5 or more servings a day was the level tied to higher risk here.
- Swap one daily soda for a piece of whole fruit, which was the trade tied to the largest drop in this analysis, a 22% lower hypertension risk. Milk and water were tied to 13% and 9% lower risk.
- Whole fruit came out clean in this analysis, so there is no reason to cut back on apples, berries, or oranges out of fear of fructose.

FAQs
Is 100% fruit juice really as bad as soda for blood pressure?
This study did not directly rank one against the other, so I would not say they are identical. What it did show is that juice at 1.5 or more servings a day carried a 35% higher risk of hypertension, which puts it in a different category than whole fruit. The likely reason is that juicing removes fiber and releases sugar that the fruit was holding inside its cells. If you want the nutrients in orange juice, eating the orange gives you the same vitamins with a slower sugar release and more fullness. Trading juice for whole fruit was linked to a 19% lower risk here.
If total fructose was not linked to hypertension, why do sugary drinks matter?
This is the most interesting tension in the paper. It suggests the problem is not the fructose molecule counted across your whole diet, but how quickly and in what form you take it in. Liquid sugar arrives fast, without fiber, and does not trigger the same fullness signals as food you chew. Drinking sugar also tends to add calories on top of what you already eat rather than replacing anything. So the delivery method, not the raw sugar total, appears to be what tracks with blood pressure.
Bottom Line
Following 25,749 people from a mean age of 12 into adulthood, researchers found that drinking two or more sugar-sweetened beverages a day was linked to a 52% higher risk of high blood pressure later in life, and fruit juice at 1.5 or more servings a day carried a 35% higher risk. Total fructose and whole fruit did not. The habits built in childhood appear to follow people for decades, and the fix in this data was refreshingly simple: trade one daily sugary drink for water, milk, or a piece of fruit.
