A recent extensive long-term study from France reveals a concerning link between certain food preservatives and the risk of hypertension and cardiovascular diseases. Researchers from Sorbonne Paris Nord and Université Paris Cité analyzed data from 112,395 participants and tracked how the consumption of preservatives affected heart health over nearly eight years. Their findings were published in the European Heart Journal.
Up to 29% Increased Risk
The numbers are striking: individuals who consume a significant amount of non-antioxidative preservatives face a 29% higher risk of developing hypertension. Additionally, the overall cardiovascular risk increases by 16%. Even antioxidative preservatives aren’t without consequences, elevating the risk of hypertension by 22%.
The researchers documented a total of 5,544 cases of hypertension and 2,450 cardiovascular events. Interestingly, about 16% of the association between non-antioxidative substances and heart disease is directly linked to the development of hypertension.
The Eight Preservatives of Concern
Among the 17 preservatives studied, eight substances were particularly associated with an increased risk of hypertension:
- Potassium sorbate (E202)
- Potassium metabisulfite (E224)
- Sodium nitrite (E250)
- Ascorbic acid (E300) and sodium ascorbate (E301)
- Sodium erythorbate (E316)
- Citric acid (E330)
- Rosemary extract (E392)
In addition, ascorbic acid was found to be linked with cardiovascular diseases. Mathilde Touvier from the French health research institute INSERM has called for a reevaluation of these additives by the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA).
Staying Calm Amidst Alarming Findings
While the results may sound alarming, experts urge caution. Monica Dinu from the University of Florence notes, “This is an observational study that shows associations but does not establish direct causality.” She recommends looking at the entire dietary profile rather than demonizing individual ingredients.
However, the study authors argue that the effects were noticeable even at typical consumption levels, emphasizing the need for a discussion on the safety of food additives.
Exploring Natural Ways to Lower Blood Pressure
For those looking to protect their cardiovascular system without resorting to medications that may have strong side effects, natural remedies may offer viable solutions. A free guide is available, detailing eight specific actions that can improve blood values within just two weeks.
Other Dietary Factors to Consider
This research adds to the growing body of evidence concerning dietary risks. Researchers at Uppsala University have found that coffee brewed from machines often contains high levels of the diterpenes cafestol and kahweol, which can increase LDL cholesterol levels. In contrast, filter coffee contains significantly lower levels of these compounds.
Furthermore, calorie-free sweeteners like aspartame or sucralose are under scrutiny. An analysis by Tufts University involving 21 clinical studies found higher fasting insulin levels and altered HbA1c levels, potentially due to changes in gut flora.
Another surprising factor is the connection between financial barriers to dental care and the risk of heart attacks and strokes. A National Institutes of Health (NIH) study involving 90,000 participants over the age of 55 indicated that improving access to dental treatment could prevent up to 4% of these diseases.
