Association Between Dietary Tomato Intake and Blood Eosinophil Count in Middle-Aged and Older Japanese Individuals: A Population-Based Cross-Sectional Study.

ABSTRACT: Background/Objectives: Although tomato consumption has been associated with positive health outcomes, it remains unclear whether it can prevent or exacerbate allergic diseases by regulating eosinophils. We explored the association between dietary tomato intake and blood eosinophil counts in Japanese individuals. Methods: This population-based, cross-sectional study included 1013 participants aged ≥ 40 years. The dietary intake of tomatoes was assessed using a validated, self-administered diet history questionnaire. The peripheral blood eosinophil count was measured, and an elevated blood eosinophil count was defined as a value that exceeded the ≥75th percentile. Results: The mean age of the participants was 62.5 ± 11.2 years, with 474 (46.8%) being male. Overall, 252 p
