Common Food Additives Linked to Hypertension and Heart Disease
Key Questions
Which food additives were linked to higher cardiovascular risk?
Preservatives such as potassium sorbate, citric acid, and synthetic ascorbic acid showed associations with increased hypertension and CVD risk. The links were independent of sodium and sugar intake.
What does the study imply about processed foods?
Harms from processed foods extend beyond macronutrients, prompting calls for regulatory re-evaluation of these additives.
Was the study observational or interventional?
It was a large observational study that identified associations between common additives and hypertension or heart disease outcomes.
A large observational study found that preservatives like potassium sorbate, citric acid, and ascorbic acid (synthetic) are associated with higher hypertension and CVD risk, independent of sodium and sugar. The findings call for regulatory re-evaluation and highlight that processed food harms extend beyond macronutrients.
