Common Preservatives May Harm Your Heart

Common food preservatives are now linked to a notable increase in cardiovascular risks, according to a recent study from France. Researchers found that preservatives commonly used to prevent bacterial and mold growth were associated with a 29% greater risk of elevated blood pressure and a 16% higher risk of heart attacks and strokes.

Even widely used antioxidant preservatives like citric acid and ascorbic acid (vitamin C) were linked to a 22% increased risk of high blood pressure. The study emphasizes that while these antioxidants occur naturally in fruits, their chemical additive forms may have different health impacts. This research highlights individual preservatives' roles in cardiovascular risk, moving beyond the broader category of ultra-processed foods.

The study, published in the European Heart Journal, analyzed data from over 112,000 participants in France. It identified eight specific preservatives associated with higher blood pressure over a decade, including non-antioxidants like potassium sorbate, potassium metabisulphite, and sodium nitrite, as well as antioxidants like citric acid and ascorbic acid.

These findings echo previous research by the same team linking similar preservatives to increased risks of cancer and type 2 diabetes. While the study is observational, its robust methodology in assessing diet and health outcomes provides strong signals warranting further investigation into the impact of food additives on public health.
