A major study involving more than 112,000 people revealed a potential link between the consumption of common food preservatives and an increased risk of high blood pressure and heart diseases. Researchers tracked participants for up to eight years. They found that individuals with the highest intake of certain preservatives had a significantly higher risk of hypertension. An increased risk of heart attack was also observed in these individuals. The study also suggests a higher risk of stroke and other cardiovascular problems. These findings highlight the importance of further research into the impact of food additives on human health.
