Three French studies reveal statistical connections between daily consumption of certain food additives and increased risks of cancer, diabetes, and cardiovascular diseases.
Three recent scientific studies conducted by French researchers have identified statistical associations between the intake of specific food additives—particularly colorants and preservatives—and a heightened risk of serious illnesses such as cancer and type 2 diabetes.
The findings also demonstrated links between these additives and increased probabilities of cardiovascular diseases and hypertension, underscoring the public health significance of the research.
These investigations were carried out by scientific teams affiliated with the French National Institute of Health and Medical Research (INSERM), INRAE, Sorbonne Paris North University, Paris City University, and the National Institute of Arts and Trades, as part of the NutriNet-Santé study, which has been monitoring over 100,000 participants since 2009.
The studies analyzed detailed dietary data collected over several years, focusing on processed food consumption. This information was cross-referenced with European and global databases to quantify individuals' intake of food additives, according to the official website of the French National Health Agency.
Initial results revealed a correlation between consumption of food colorants and an up to 38% increased risk of developing type 2 diabetes among the highest consumers compared to the lowest.
Furthermore, the research recorded a 14% overall increased risk of cancer linked to these additives, with breast cancer risk rising by 21%, particularly showing a greater increase in postmenopausal breast cancer cases.
The researchers noted that certain colorants, including caramel, beta-carotene, and curcumin, were significantly associated with higher risk levels.
The third study concentrated on preservatives, indicating a 24% higher risk of hypertension among the highest-consuming groups, alongside a 16% increased risk of cardiovascular diseases linked to some preservatives.
Results also showed that substances such as potassium sorbate and citric acid were clearly connected to elevated hypertension rates.
The investigators emphasized that these findings represent the first large-scale analysis linking a broad range of food additives to chronic diseases, aligning with previous laboratory studies that demonstrated adverse health effects from some of these substances.
They urged health authorities to reassess the safety of these food additives and to adopt stricter regulatory approaches regarding their use, especially given their widespread presence in processed foods.
In light of these outcomes, the researchers stressed the importance of reducing consumption of ultra-processed foods and favoring fresh or minimally processed foods, in accordance with France's national healthy nutrition program recommendations, to minimize unnecessary exposure to food additives.
A novel and innovative program for early lung cancer detection has recently been introduced, aiming to reduce the high mortality rates associated with the disease.
This initiative utilizes advanced imaging techniques combined with artificial intelligence analysis, prompting questions about its objectives and participation procedures.
Following early detection programs for breast, colon, and cervical cancers, lung cancer is now the focus of a new automated screening program.
The pilot phase of the "IMPULSION" program—short for "Implementation of Lung Cancer Screening in Populations"—began on May 11, targeting training and employment needs, particularly for radiologists and addiction treatment specialists, along with technical requirements.
According to the French network CNews, lung cancer is among the most prevalent and deadly cancers, with incidence rates increasing by 5% annually over the past decade. It is often diagnosed at advanced stages in three-quarters of cases.
The IMPULSION program aims to facilitate early detection of lung cancer and promote smoking cessation.
Preliminary studies published by the National Cancer Institute suggest that mortality from lung cancer could be reduced by 20% to 25%, potentially reaching 38% if screening is combined with quitting smoking.
Volunteers initially undergo a low-dose chest CT scan, a painless procedure lasting less than ten minutes. Results are first reviewed by a radiologist and then analyzed by artificial intelligence.
If abnormalities are detected, patients are referred for specialized consultation. If results are normal, screening is repeated after one year and then every two years thereafter.
The program currently targets French citizens aged 50 to 74 who are smokers or former smokers with a history of smoking at least two packs per day for ten years or one pack per day for twenty years, having quit less than 15 years ago. Participants must reside in one of five regions: Île-de-France, Rhône-Alpes, Hauts-de-France, Pays de la Loire, or Provence-Alpes-Côte d'Azur.
This initial phase uses these five regions as a pilot model, with plans to expand the program nationwide by 2027.
The National Cancer Institute indicates that if expected outcomes are achieved, this project could serve as a model for large-scale lung cancer screening implementation by 2030.
