Do sugary drinks in childhood lead to high blood pressure in adulthood?
Yes. 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.
This is one of the longest looks at this question we have. Researchers used the Growing Up Today Study, which enrolled participants around age 12 and tracked them into their thirties and forties. Diet was not measured once and forgotten. Participants filled out food records 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 quietly 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 at age 45.
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 little or none. That is not a small bump. It is roughly a one-and-a-half-fold increase in the odds of a condition that drives heart attacks, strokes, and kidney disease.
Fruit juice was the surprise. At 1.5 or more servings a day, juice was also significantly linked to higher hypertension risk. Meanwhile, total fructose intake showed no association at all, 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. Swapping a single daily serving of sugary drinks or juice for whole fruit, milk, or water was linked to lower hypertension risk. For the fruit juice swap, risk dropped by up to 22%.
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 we do.
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 about age 12 into adulthood, 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 22% figure describes 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, and keep it under about one and a half servings a day if you drink it at all.
- Swap one daily glass of juice or soda for water, milk, or a piece of whole fruit, which is the exact trade this study connected to up to 22% lower hypertension 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 was significantly linked to higher hypertension risk, 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.
How much is one serving of a sugar-sweetened beverage?
In nutrition research a serving is usually a standard glass or can, roughly 8 to 12 ounces. That matters, because the bottles most people actually buy are far larger. A 20-ounce bottle of soda is closer to two servings than one, which means the two-serving threshold tied to 52% higher risk in this study is easier to cross than it sounds. Checking the label for servings per container is a fast reality check.
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 nearly 26,000 people from around age 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 carried risk as well. 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.
