Skip The Juice Box: Study Links Childhood Sugary Drinks To Hypertension In Adulthood

Drinking 2+ Sugary Beverages Daily as a Child Linked to 52% Higher High Blood Pressure Risk Decades Later

Parents have long been told that fruit juice is a wholesome alternative to soda, a natural, vitamin-packed drink that belongs in a child’s lunchbox. A new study that followed more than 25,000 young people for up to 25 years tells a far more complicated story: both sugary drinks and 100% fruit juice were linked to a higher risk of developing high blood pressure by adulthood. Swapping either for whole fruit was associated with a lower risk.

High blood pressure, a condition in which the force of blood against artery walls stays consistently too high, affects more than 1 billion people worldwide and contributes to an estimated 9.4 million deaths each year, according to the study, published in the journal Circulation. Most prior studies on diet and blood pressure focused on adults. This one began tracking kids from an average starting age of 12 and followed their health for decades, giving researchers an unusually long window into how early eating habits shape long-term disease risk.

Recruited From Nurses’ Health Study Families, Participants Reported Diets Every Few Years

Researchers drew from a project called the Growing Up Today Study, which recruited children of nurses across the United States in two waves, one starting in 1996 and another in 2004. In total, 25,749 participants were tracked from an average starting age of 12 through to an average age of 36, with 55% female and 96% non-Hispanic White.

Every one to four years, participants filled out detailed questionnaires about diet, exercise, sleep, and health. By the end of follow-up in 2021, 1,625 participants, about 6.3% of the group, had reported a diagnosis of high blood pressure. The median age at diagnosis was 36.

Even after adjusting for physical activity, screen time, sleep, smoking, body weight, and overall diet quality, the links between sugary drinks, fruit juice, and high blood pressure held up.

Soda, Sports Drinks, and Juice All Raise High Blood Pressure Risk

When researchers looked at sugar-sweetened beverages, including sodas, fruit-flavored drinks like lemonade and fruit punch, and sports drinks, the association was stark. People who consumed two or more servings per day, compared to those drinking fewer than three per week, had a 52% higher risk of developing high blood pressure. Each additional daily serving was associated with a 14% higher risk.

Soda was linked to a 23% higher risk per daily serving, while sports drinks were tied to a 36% higher risk. That sports drink finding deserves attention because these beverages are often marketed as health-promoting, even though researchers grouped them with other sugary drinks and noted they contain added sugars and sodium that may raise blood pressure through excess energy intake and sodium retention.

Fruit juice told a similar story at high intake levels. People drinking one and a half or more servings per day had a 35% higher risk compared to those drinking less than one serving per week. Orange juice specifically was associated with a 20% higher risk per daily serving, while apple and other juice types did not show a statistically meaningful link. Researchers noted that the orange juice finding may partly reflect misclassification, since orange-flavored sugary drinks are commonly consumed by children and may sometimes have been reported as orange juice.

Whole Fruit Carries None of the Same Blood Pressure Risk as Juice

Perhaps the most practical takeaway involves what families can reach for instead. Whole fruit, including apples, oranges, bananas, grapes, and strawberries, showed no meaningful link to high blood pressure even at high intake levels. Replacing one daily serving of a sugary drink with whole fruit was associated with a 22% lower risk. Swapping for milk was linked to a 13% lower risk, and switching to water was tied to a 9% lower risk. Replacing a daily serving of 100% fruit juice with whole fruit was associated with a 19% lower risk.

Why does whole fruit behave so differently from juice when both contain natural sugars? Fruit juice contains free sugars and lacks the fiber and plant compounds found in whole fruit. Processing strips away those nutrients, which are thought to slow sugar absorption and support heart health.

Study Caveats Don’t Erase 25 Years of Data

Because this was an observational study, the results cannot definitively prove that juice or soda caused high blood pressure. Diet was self-reported through questionnaires, introducing some imprecision. And because the group was made up almost entirely of non-Hispanic White participants, the results may not apply equally across racial or ethnic backgrounds.

Still, tracking more than 25,000 people for up to 25 years beginning in childhood gives these findings unusual weight. High blood pressure used to be thought of as an adult problem. This research makes clear that the dietary habits shaping that risk begin far earlier than most people assume, and that a glass of juice at breakfast may not be the health win it has long been marketed as.
