A recent French study found that common food preservatives, including those labeled as 'natural' like citric and ascorbic acid, are associated with a 29% higher risk of elevated blood pressure and a 16% increased risk of heart attacks and strokes. The findings highlight the health risks of ultraprocessed foods and suggest consumers opt for minimally processed options.
- 01The study analyzed the diets of over 112,000 participants and identified 58 preservatives linked to cardiovascular health.
- 02Eight preservatives were found to be associated with higher blood pressure, including potassium sorbate and sodium nitrite.
- 03The research indicates that 'natural' preservatives can still pose health risks when used in processed foods.
- 04Prior studies by the same team linked preservatives to increased risks of cancer and type 2 diabetes.
- 05The findings advocate for a diet rich in fresh, unprocessed foods to mitigate health risks.

A study published in the European Heart Journal reveals that common food preservatives, even those labeled as 'natural,' are linked to significant health risks. Researchers from France's NutriNet-Santé study examined the diets of over 112,000 participants and found that preservatives like citric and ascorbic acid are associated with a 29% increased risk of elevated blood pressure and a 16% greater risk of heart attacks and strokes. The study highlights that while these preservatives occur naturally in fruits, their processed forms can have detrimental effects on health. The research also identified eight preservatives linked to higher blood pressure, including potassium sorbate and sodium nitrite, commonly used in various processed foods. Previous studies have similarly connected these preservatives to increased risks of cancer and type 2 diabetes. Given the prevalence of preservatives in the food supply, researchers recommend consumers prioritize fresh and minimally processed foods to improve cardiovascular health.
