A study published in the European Heart Journal has found that eight commonly used food preservatives may be linked to a higher risk of high blood pressure and cardiovascular disease. The research, led by Dr. Mathilde Touvier and Anaïs Hasenböhler from the Nutritional Epidemiology Research Team at two French universities, analyzed data from over 112,000 volunteers in France. Over a period of seven to eight years, the study tracked whether participants developed high blood pressure or cardiovascular conditions like heart attacks, strokes, or angina. To gather detailed dietary habits, participants recorded what they ate and drank over three-day periods every six months. Nearly all participants—99.5%—had consumed at least one food preservative within the first two years of the study. The strongest links to health risks were found among those who consumed the highest amounts of certain preservatives. For example, individuals with the highest intake of non-antioxidant preservatives had a 29% greater risk of developing high blood pressure and a 16% higher risk of cardiovascular disease compared to those with the lowest intake. Those consuming the most antioxidant preservatives had a 22% higher risk of hypertension. The eight preservatives specifically linked to high blood pressure were potassium sorbate (E202), potassium metabisulphite (E224), sodium nitrite (E250), ascorbic acid (E300), sodium ascorbate (E301), sodium erythorbate (E316), citric acid (E330), and rosemary extracts (E392). Ascorbic acid (E300), also known as vitamin C, was also linked to a higher risk of cardiovascular disease. It is important to note that this study is observational, meaning it identifies statistical patterns rather than proving direct cause and effect. Researchers suggest that preservatives may contribute to health risks by causing oxidative stress or affecting how the pancreas functions. The findings have prompted calls for regulatory bodies like the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA) to reassess the safety of these additives. In the meantime, the study supports current dietary guidelines that encourage people to choose whole, unprocessed foods and limit the intake of unnecessary food additives.
