Effect of dietary patterns on serum C-reactive protein level

Area of Science:

• Nutrition Science
• Epidemiology
• Cardiovascular Health

Background:

• C-reactive protein (CRP) is a key inflammation marker.
• Elevated CRP predicts cardiovascular disease and metabolic syndrome risk.
• Dietary patterns may modulate inflammation and disease risk via CRP.

Purpose of the Study:

• To investigate the association between dietary patterns and blood CRP levels.
• To explore potential gender and blood pressure interactions in this relationship.

Main Methods:

• Cross-sectional analysis of 7574 middle-aged Korean adults.
• Factor analysis identified four dietary patterns: 'fruit', 'vegetable', 'meat', 'coffee'.
• Multiple linear regression adjusted for covariates to assess diet-CRP associations.

Main Results:

• A 'vegetable' dietary pattern showed a significant inverse association with CRP levels.
• Higher adherence to the 'vegetable' pattern correlated with lower CRP.
• This inverse association was more pronounced in men with hypertension.

Conclusions:

• The 'vegetable' dietary pattern is inversely associated with C-reactive protein.
• This association is particularly significant in hypertensive men, highlighting a potential dietary intervention target.
