A new study has raised concerns about the health effects of common food preservatives linking them to an increased risk of high blood pressure, heart attacks and stroke.
Researchers found that people who consumed higher amounts of preservatives had a 29% greater risk of elevated blood pressure and a 16% higher risk of cardiovascular events.
Even preservatives often considered “natural,” such as citric acid and ascorbic acid (vitamin C) were associated with a 22% higher risk of high blood pressure when consumed in larger amounts through processed foods.
The study analyzed data from more than 112,000 participants over several years making it one of the largest investigations into individual food additives and their health effects.
Experts explain that while these substances occur naturally in fruits and vegetables, their added and processed forms may behave differently in the body.
Common sources of these preservatives include processed meats, packaged snacks, sauces and beverages such as soft drinks and juices.
While preservatives play an important role in preventing food spoilage and reducing foodborne illness, frequent consumption of preservative-rich foods may carry long-term health risks.
The findings also highlight concerns around ultra-processed foods, which have already been linked to obesity, diabetes and cardiovascular disease.
However, researchers emphasize that the study is observational and does not prove direct cause and effect, though it provides strong evidence for further investigation.
Health experts recommend choosing fresh or minimally processed foods, reading ingredient labels carefully and limiting intake of highly processed products to reduce potential risks.
