Understanding the Mediterranean Diet's Impact on Lowering Mortality Risk Among American Women
- Researchers at Brigham and Women’s Hospital have investigated the core reasons behind the Mediterranean diet's association with a 23 percent reduction in overall mortality risk among American women.- While numerous studies have highlighted the health benefits of the Mediterranean diet, there has been limited long-term data on its effects specifically on U.S. women. Additionally, the exact mechanisms behind the diet's potential to lower mortality risk have remained unclear.
- A new study, tracking over 25,000 initially healthy American women for up to 25 years, was conducted by researchers from Brigham and Women’s Hospital, part of the Mass General Brigham healthcare system. They discovered that women who adhered more closely to the Mediterranean diet had up to a 23% lower risk of all-cause mortality, including significant benefits for both cancer-related and cardiovascular-related deaths.
- The researchers found biological changes that might explain these benefits, such as alterations in biomarkers related to metabolism, inflammation, and insulin resistance. These findings are published in JAMA.
- “For women seeking to live longer, our study emphasizes the importance of diet. Following a Mediterranean dietary pattern could reduce the risk of death by about a quarter over more than 25 years, benefiting both cancer and cardiovascular mortality, the leading causes of death for women (and men) in the US and globally,” said senior author Samia Mora, MD, a cardiologist and director of the Center for Lipid Metabolomics at Brigham.
Diet Details and Research Insights
- The Mediterranean diet emphasizes a diverse intake of plant-based foods, such as nuts, seeds, fruits, vegetables, whole grains, and legumes. Olive oil, particularly extra virgin, is the primary source of fat. The diet also includes moderate consumption of fish, poultry, dairy, eggs, and alcohol, with meats, sweets, and processed foods being eaten rarely.- The study examined the long-term benefits of adhering to the Mediterranean diet among participants in the Women’s Health Study. It focused on the biological mechanisms that might explain its health benefits, evaluating approximately 40 biomarkers representing various biological pathways and clinical risk factors.
- The most significant contributors to the benefits were biomarkers of metabolism and inflammation, followed by triglyceride-rich lipoproteins, adiposity, and insulin resistance. Other contributing factors included branched-chain amino acids, high-density and low-density lipoproteins, glycemic measures, and hypertension.
- “Our research offers significant public health insights: even modest improvements in established risk factors for metabolic diseases—particularly those linked to small molecule metabolites, inflammation, triglyceride-rich lipoproteins, obesity, and insulin resistance—can provide substantial long-term benefits from adhering to a Mediterranean diet,” said lead author Shafqat Ahmad, PhD, an associate professor of Epidemiology at Uppsala University, Sweden, and a researcher at Brigham’s Center for Lipid Metabolomics and Division of Preventive Medicine.
Study Limitations and Cultural Adaptations
- The study identified crucial biological pathways that might explain the reduced mortality risk. However, the authors noted several limitations. The study population was primarily middle-aged and older, well-educated, non-Hispanic white female health professionals. Additionally, it relied on self-reported measures, such as food-frequency questionnaires, height, weight, and blood pressure. Despite these limitations, the study's strengths include its large scale and extensive follow-up period.- The researchers also noted that as the Mediterranean diet has gained popularity, it has been adapted to different countries and cultures.
- “The Mediterranean diet’s health benefits are well-recognized by medical professionals, and our study provides insights into why it may be so beneficial. Public health policies should promote the healthy attributes of the Mediterranean diet and discourage unhealthy adaptations,” Mora concluded.
Conclusion
- The comprehensive study conducted by researchers at Brigham and Women’s Hospital offers compelling evidence that adherence to the Mediterranean diet is associated with a significant reduction in mortality risk among American women. By tracking over 25,000 initially healthy women for up to 25 years, the researchers found that those who followed the Mediterranean dietary pattern had a 23% lower risk of all-cause mortality, with notable benefits for both cancer and cardiovascular mortality. The study's findings highlight the diet's potential to promote longevity through beneficial biological changes in metabolism, inflammation, and insulin resistance.
- Despite some limitations, such as the homogeneity of the study population and reliance on self-reported data, the study's large scale and long follow-up period provide robust support for the Mediterranean diet's health benefits. The research underscores the importance of dietary habits in reducing mortality risk and encourages public health policies to promote the Mediterranean diet's healthful attributes.
- The Mediterranean diet stands out as a powerful tool for enhancing health and longevity, offering a practical dietary approach to significantly reduce the risk of major causes of death. This study not only reinforces the diet's benefits but also provides valuable insights into the biological mechanisms at play, advocating for a broader adoption of this dietary pattern to improve public health outcomes.
