A large-scale observational study of over 112,000 adults has identified links between eight common food preservatives and increased high blood pressure risk. The findings, published in the European Heart Journal, highlight the potential health impacts of additives frequently used in processed products.
Why it matters
With nearly 120 million U.S. adults already managing high blood pressure, identifying dietary contributors like industrial additives is essential for cardiovascular health. This research underscores the need for greater transparency and scrutiny regarding ingredients in modern processed diets.
In a study published in the European Heart Journal, researchers followed 112,395 adults for a median of nearly eight years. The study found heavy consumption of three non-antioxidant preservatives correlated with a 29% higher blood pressure risk, while five antioxidant preservatives showed a 22% increase.
The players
European Heart Journal
A leading peer-reviewed medical publication that covers cardiovascular research and global heart health developments.
The details
The study analyzed a broad cohort of adults to track how specific industrial additives affect cardiovascular health over time. Researchers specifically adjusted their models to isolate the effects of added preservatives like vitamin C from the intake of natural vitamin C found in whole foods. Among the eight preservatives studied, researchers also identified ascorbic acid as the sole additive linked to an increased risk of heart disease.

Health Landscape
This study extends the current research into the health consequences of ultra-processed food consumption by identifying specific, commonly used preservatives as potential cardiovascular risk factors. It marks a shift from looking at general processed food labels to evaluating the individual physiological impact of specific additive ingredients.
If you are managing high blood pressure, it is worth discussing your intake of processed foods with your physician to identify if specific preservatives like those in cured meats or sodas are present in your diet. Tracking your blood pressure regularly is a key step in understanding how dietary changes may impact your overall cardiovascular health.
The takeaway
This study suggests that common additives, including preservatives found in wine, cheese, and soda, may contribute to elevated blood pressure. Consider prioritizing whole foods over processed alternatives and discuss any concerns about additive intake with your healthcare provider at your next checkup.
