Ultra-processed foods and increased high sensitivity C-reactive protein

Area of Science:

• Nutrition Science
• Cardiovascular Health
• Inflammation Biomarkers

Background:

• Ultra-processed foods (UPFs) are prevalent in Western diets.
• High sensitivity C-reactive protein (hs-CRP) is a key inflammatory marker and predictor of cardiovascular disease (CVD).
• The association between UPF consumption and hs-CRP requires further investigation in representative populations.

Purpose of the Study:

• To determine if increased consumption of ultra-processed foods is associated with significantly elevated hs-CRP levels.
• To analyze the relationship between varying percentages of energy intake from UPFs and hs-CRP.
• To assess the clinical and public health implications of UPF consumption on inflammation.

Main Methods:

• Utilized data from 9,254 participants in the US National Health and Nutrition Examination Survey.
• Quantified ultra-processed food intake as a percentage of total energy using the NOVA classification system.
• Employed logistic regression analyses, adjusting for confounders like age, sex, smoking, and physical activity.

Main Results:

• Individuals consuming the highest amounts of UPFs (60-79% of energy intake) showed significantly increased hs-CRP levels (RR=1.11).
• A significant increase in hs-CRP was also observed in those consuming 40-59% of energy from UPFs (RR=1.14).
• A non-significant increase was noted for 20-39% UPF intake, while the lowest quartile (0-19%) served as the reference.

Conclusions:

• This study demonstrates a significant association between high ultra-processed food consumption and elevated hs-CRP levels in a large, representative US sample.
• The findings underscore the potential role of UPFs in promoting inflammation and increasing cardiovascular disease risk.
• Results have significant implications for public health policy, clinical practice, and future research on dietary patterns and chronic disease.
