A Proinflammatory Diet May Increase Mortality Risk in Patients with Diabetes Mellitus

Area of Science:

• Nutrition Science
• Epidemiology
• Public Health

Background:

• The relationship between diet and chronic disease, particularly diabetes mellitus, is a significant public health concern.
• Understanding the impact of dietary patterns on disease progression and mortality is crucial for effective health interventions.

Purpose of the Study:

• To investigate the association between a proinflammatory diet, assessed by the dietary inflammatory index (DII), and the risk of developing diabetes mellitus.
• To determine if a proinflammatory diet increases all-cause mortality risk in patients already diagnosed with diabetes mellitus.

Main Methods:

• Observational study utilizing data from the National Health and Nutrition Examination Survey (NHANES) and National Death Index (NDI) (2009-2014).
• Dietary inflammatory potential was quantified using the dietary inflammatory index (DII) based on 24-hour dietary recalls.
• Mortality data was linked to NHANES participants following established NCHS protocols.

Main Results:

• In a general population sample (n=15,291), higher DII scores were positively associated with fasting glucose, glycohemoglobin, and the risk of diabetes.
• Among participants with diabetes (n=1904), adherence to a proinflammatory diet was associated with a significantly higher risk of all-cause mortality (HR=1.71).
• The study found a positive association between DII and diabetes prevalence.

Conclusions:

• A proinflammatory dietary pattern is associated with an increased prevalence of diabetes mellitus.
• Individuals with diabetes mellitus consuming a proinflammatory diet face a heightened risk of all-cause mortality.
• These findings underscore the importance of dietary modifications in managing diabetes and improving patient outcomes.
