Preservatives in everyday foods linked to higher blood pressure and heart risks, French study finds
A large French NutriNet-Santé study of over 112,000 participants finds that certain widely used preservatives, including antioxidant additives like ascorbic acid, are associated with higher blood pressure and an increased risk of heart attack and stroke; eight preservatives were linked to hypertension and some (including non-antioxidants like potassium sorbate and sodium nitrite) to cancer risk, with findings observational in nature and not proving causation, but reinforcing concerns about ultraprocessed foods and recommending fresher or properly frozen options when possible.
