Summary
Dietary interventions effectively prevent type 2 diabetes mellitus (DM) progression from prediabetes states like impaired glucose tolerance (IGT) and impaired fasting glucose (IFG). Lifestyle changes are a cost-effective strategy to manage DM and reduce cardiovascular disease (CVD) risk.
Area of Science:
- Endocrinology
- Nutritional Science
- Preventive Medicine
Background:
- Impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) are recognized prediabetes states.
- Prediabetes is linked to an increased risk of cardiovascular disease (CVD).
- Type 2 diabetes mellitus (DM) poses a significant public health burden.
Purpose of the Study:
- To highlight the efficacy of diet intervention in preventing type 2 DM progression.
- To emphasize nutritional therapy as a primary strategy for prediabetes management.
- To underscore the role of lifestyle modifications in controlling diabetes.
Main Methods:
- Review of studies demonstrating diet intervention effectiveness (e.g., Da Quin IGT and DM study, Finnish Diabetes Prevention Study, Diabetes Prevention Program).
- Focus on weight reduction and increased physical activity.
- Emphasis on dietary composition: reduced fat intake, altered polyunsaturated fatty acid (PUFA) ratios (n-6 to n-3), increased fiber-rich carbohydrates, and antioxidant intake.
Main Results:
- Diet intervention is a superior method for controlling prediabetes progression to type 2 DM.
- Lifestyle changes, including diet and exercise, offer long-term health benefits.
- Nutritional strategies are cost-effective tools for managing the national burden of type 2 DM.
Conclusions:
- Preventing type 2 DM is achievable through dietary changes and lifestyle modifications.
- Faulty nutrition is a primary driver of the diabetes epidemic.
- Nutritional therapy is the most viable option for managing prediabetes.
