Mediterranean Diet May Significantly Lower Diabetes Risk
A recent study suggests that adopting a Mediterranean diet, rich in fruits, vegetables, and healthy fats, along with certain lifestyle changes, could reduce the risk of developing type 2 diabetes by nearly a third. This research was published in the Annals of Internal Medicine on August 25.
The study followed nearly 4,800 older adults in Spain who were overweight or obese and at risk of diabetes for six years. Participants who adhered to the Mediterranean diet while also managing their calorie intake and engaging in regular exercise saw their diabetes risk drop by 31%.
Miguel Martínez-González, a co-author and professor at the University of Navarra in Spain, highlighted the practical benefits of the study. He mentioned that incorporating calorie control and physical activity into this diet prevented about three out of every 100 people from developing diabetes. This finding represents a significant public health advantage.
Type 2 diabetes is rapidly increasing worldwide, now affecting nearly 16% of adults in the U.S., according to the Centers for Disease Control and Prevention (CDC). Experts agree that small lifestyle changes can prevent millions of new cases.
Key Features of the Mediterranean Diet
The Mediterranean diet emphasizes:
- A lot of fruits and vegetables.
- Whole grains.
- Healthy fats, especially from olive oil and nuts.
- Moderate amounts of fish and lean proteins.
- Minimal red meat.
This eating pattern has been linked to better heart health, improved insulin sensitivity, and lower levels of inflammation. Lauren Harris-Pincus, a registered dietitian, notes that high-fiber foods like fruits, veggies, beans, nuts, and whole grains are essential for maintaining gut health and preventing diseases.
Study Overview
In the study, participants were divided into two groups. One group followed the Mediterranean diet while also cutting around 600 calories per day, exercising moderately, and receiving professional weight-loss support. The other group followed the Mediterranean diet without additional restrictions or support.
After six years, those in the first group had a 31% lower risk of developing diabetes and lost an average of about 7 pounds, along with a reduction in waist size. The second group experienced little change, losing only about 1.3 pounds.
Co-author Jordi Salas-Salvadó emphasized that effective diabetes prevention combines a healthy diet with weight loss and increased physical activity. While the Mediterranean diet is not the only option, it is a sustainable long-term choice for those looking to manage their weight.
Considerations
The study’s design makes it tough to pinpoint which lifestyle change had the biggest effect, and the findings are based on older adults in Spain. More research is needed to see if these results apply to younger people or those from different cultures.
Dr. Marc Siegel, a medical analyst at NYU Langone, pointed out that diets high in saturated fats and sugars increase the risk of several chronic diseases, underscoring the importance of healthy eating.
In summary, adopting a Mediterranean diet along with healthy lifestyle practices could play a crucial role in reducing diabetes risk.
