A new study published in the European Heart Journal is adding more nuance to the conversation about ultraprocessed foods and blood pressure. Instead of treating all ultraprocessed foods as a single category, researchers looked more closely at the specific ingredients commonly used in these products—and found that some markers of ultraprocessing appear to be more strongly linked to increased hypertension risk than others.
That distinction matters. Ultraprocessed foods have long been associated with poorer health outcomes, but “ultraprocessed” is a broad label. It includes everything from packaged snacks and sweetened drinks to flavored yogurt, protein bars, and reformulated breads. This study suggests the health story may be even more complicated: not all ingredients used in these foods appear to carry the same risk signal.
The Main Takeaway: Some Ingredients Stood Out
Researchers used data from the UK Biobank to conduct a large prospective cohort study focused on incident arterial hypertension—in other words, new cases of high blood pressure that developed over time. The study included 101,560 adults, with a median age of 56, all of whom were free of hypertension at the start.
Participants completed between one and five web-based 24-hour dietary assessments between April 2009 and June 2012. Researchers then linked those self-reported dietary records to a database of 2,459 supermarket products in the UK to estimate exposure to ingredients commonly found in ultraprocessed foods.
The participants were followed for a median of 10.5 years. During that time, 7,633 people developed hypertension.
The headline finding is straightforward: higher consumption of foods containing certain ultraprocessing ingredients was associated with a greater risk of incident hypertension. Specifically, the study found stronger associations for foods containing:
- Coloring agents
- Sweeteners
- Flavorings
- Varieties of sugar
These ingredient groups were linked to higher hazard ratios for hypertension, suggesting that they were associated with greater risk over the follow-up period. When researchers looked at individual ingredients, several stood out as being associated with a higher risk, including:
- Aspartame
- Acesulfame
- Sucralose
- Xylitol
- Erythritol
- Saccharin
- Bulking agents
- Dextrose
- Fructose
- Hydrolysed protein
- Whey protein
In contrast, some other ingredient categories—such as flavor enhancers, processing aids, modified oil, added fiber, and protein source ingredients overall—were not significantly associated with incident hypertension in this analysis.
Why This Matters
For years, public health advice has warned against diets high in ultraprocessed foods. That message remains important. But this study suggests that the risk may not come simply from how “processed” a food is overall. Instead, it may be certain combinations of additives and reformulation ingredients that deserve more attention.
That’s useful for several reasons. First, it gives researchers a more precise way to study why ultraprocessed foods may be harmful. If sweeteners, colorings, and some sugar-related ingredients are more strongly associated with hypertension, that may point toward mechanisms involving appetite regulation, metabolic effects, sodium and water balance, or other physiological pathways that still need more investigation.
Second, it may help clinicians and nutrition professionals give more targeted advice. Rather than focusing only on a generic “avoid ultraprocessed foods” message, future counseling could emphasize limiting products heavy in added sweeteners, certain sugars, and flavoring systems.
Third, it may help consumers make better decisions at the grocery store. Many people assume that a product labeled “high protein,” “sugar-free,” or “diet” is automatically a healthier choice. This study suggests that ingredient lists still matter—and that some reformulated products may still carry a blood pressure downside.

What the Results Do Not Mean
It is important not to overstate the findings. This was an observational study, which means it can show associations, but it cannot prove cause and effect. People who eat more of these ingredients may differ in other ways that influence blood pressure, such as overall diet quality, physical activity, stress, income, sleep, or access to healthcare.
The study also relied on self-reported dietary data, which can be imperfect. And because the analysis did not account for changes in diet over time, it may not fully reflect participants’ long-term eating patterns.
Hypertension was identified using diagnostic codes, which may have underestimated the true number of cases. That means the study is informative, but not definitive.
A Shift from “Ultraprocessed” to “What’s Inside”
One of the most interesting implications of this research is that the nutrition conversation may be shifting from broad food categories to the specific ingredients that define them.
For example, two foods can both be ultraprocessed, but they may not be equally relevant to blood pressure risk. A protein-fortified snack with added sweeteners and flavorings may not have the same health impact as a product containing fiber and fewer additives. This study suggests that ingredient profiling could eventually become an important tool for identifying which ultraprocessed foods matter most from a cardiovascular standpoint.
That doesn’t mean consumers need to become food chemists. But it does mean that reading labels more carefully may be worthwhile, especially for people trying to manage blood pressure or reduce cardiovascular risk.
In the end, the message is not just “eat fewer ultraprocessed foods.” It may increasingly be “pay attention to what those foods are made of.”
