Few epidemiologic studies have examined the potential cardiovascular mechanisms 
of tomato-based food products, the primary dietary source of lycopene. We 
examined the cross-sectional association between tomato-based food product 
intake and coronary biomarkers in the Women's Health Study. Tomato-based food 
products (tomatoes, tomato juice, tomato sauce, pizza) were summed from a 
semiquantitative FFQ and multiple risk factors ascertained. Plasma from baseline 
blood samples were assayed for lipids, lipoproteins, hemoglobin A1c, C-reactive 
protein, fibrinogen, soluble intracellular adhesion molecule-1, and creatinine. 
A total of 27,261 women aged ≥45 y who were free of cardiovascular disease and 
cancer provided relevant data for this study. Tomato-based food product intake 
was modest, with 84% of women consuming <1 serving/d, but those with greater 
intake had healthier lifestyle and dietary habits. Women consuming ≥10 compared 
with <1.5 servings/wk of tomato-based food products had significant but 
clinically modest improvements in total cholesterol (TC) (5.38 vs. 5.51 mmol/L; 
P = 0.029), the TC:HDL cholesterol ratio (4.08 vs. 4.22; P = 0.046), and 
hemoglobin A1c (5.02 vs. 5.13%; P < 0.001) in multivariable models. Considering 
clinical cutpoints, women consuming ≥10 compared with <1.5 servings/wk were 31% 
(95% CI = 6%, 50%), 40% (95% CI = 13%, 59%), and 66% (95% CI = 20%, 86%) less 
likely to have elevated TC (≥6.21 mmol/L), LDL cholesterol (≥4.14 mmol/L), and 
hemoglobin A1c (≥6%), respectively. Other coronary biomarkers were unassociated 
with tomato-based food products. In conclusion, women consuming ≥10 compared 
with <1.5 servings/wk of tomato-based food products had clinically modest but 
significant improvements in TC, the TC:HDL cholesterol ratio, and hemoglobin A1c 
but not other coronary biomarkers.
