Tomato products like sauce and juice are good for heart health. While lycopene is a key compound, other natural substances in tomatoes also contribute to these benefits.
See the scientific wording
The cardiovascular benefits associated with consumption of tomato products are not exclusively attributable to lycopene but may also be contributed by other bioactive compounds present in tomatoes.

What the research says
3 studies reviewedSupporting (3)
Cohort StudyHuman2025
People who drank tomato juice had less inflammation in their blood, which is good for heart health. This suggests that tomato juice helps, and since it contains many natural substances besides lycopene, it supports the idea that other compounds also matter.
Tomato‐Soy Juice Reduces Inflammation and Modulates the Urinary Metabolome in Adults With Obesity
Randomized Controlled TrialHuman2026
The study gave people either a tomato drink with lots of lycopene or one with hardly any lycopene, and both helped reduce inflammation. This shows that tomatoes have other healthy substances besides lycopene.
Systematic Review With Meta-AnalysisMeta-analysis2017
The study found that eating whole tomatoes helps lower bad cholesterol and inflammation and improves blood vessel function, but taking just lycopene (the main compound) only lowered blood pressure—so other tomato stuff must be helping too.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Tomatoes contain different substances that get into your blood and tell your body to stop making too many inflammatory signals. When these signals are reduced, your blood vessels stay healthy and your heart is protected.

Tomato products like sauce and juice are good for heart health. While lycopene is a key compound, other natural substances in tomatoes also contribute to these benefits.
Mechanism
3 studiesTomatoes have many helpful substances, not just lycopene. These substances work together to turn down the body's inflammation alarm, which keeps blood vessels healthy and reduces heart disease risk.
Tomatoes contain different substances that get into your blood and tell your body to stop making too many inflammatory signals. When these signals are reduced, your blood vessels stay healthy and your heart is protected.
Lycopene and flavonoids (e.g., naringenin) from tomato products are absorbed from the gastrointestinal tract and enter the systemic circulation.
These compounds inhibit the phosphorylation of IκB and activation of ERK in adipose and vascular tissues, blocking NF-κB and ERK signaling pathways.
Inhibition of NF-κB and ERK reduces the transcription of pro-inflammatory cytokines, including IL-5, IL-12p70, GM-CSF, and TNF-α.
Lower levels of these cytokines decrease systemic inflammation, improve endothelial function, reduce oxidative stress, and lower cardiovascular risk factors such as cholesterol and blood pressure.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review of Randomized Controlled Trials on Tomato Product Consumption and Cardiovascular Outcomes
Systematic review of RCTs comparing whole tomato product intake (e.g., tomato sauce, juice) to lycopene supplements or placebo, measuring cardiovascular endpoints (e.g., blood pressure, LDL oxidation, endothelial function) over at least 4 weeks.
Randomized Controlled Trial Comparing Whole Tomato Product vs. Lycopene Supplement on Cardiovascular Risk Markers
Parallel-group RCT: participants randomly assigned to consume tomato products (e.g., 200g cooked tomatoes daily), lycopene supplement (matched to lycopene content), or placebo for 12 weeks. Outcomes: changes in blood pressure, lipid profile, inflammatory markers (CRP, IL-6), and oxidative stress markers.
Prospective Cohort Study Examining Association between Long-Term Tomato Intake and Cardiovascular Disease Incidence
Large prospective cohort (e.g., 50,000 adults) with validated food frequency questionnaires repeated every 4 years, tracking tomato product intake and lycopene intake. Follow-up for 10+ years for major adverse cardiovascular events (MI, stroke, CVD death). Statistical models adjust for known confounders and examine whether the association remains after controlling for lycopene intake.
Case-Control Study Comparing Tomato Consumption in Cardiovascular Patients vs. Healthy Controls
Cases: individuals with incident cardiovascular disease (e.g., first myocardial infarction) identified from hospital registries. Controls: age- and sex-matched healthy individuals. Dietary assessment via validated food frequency questionnaire focusing on tomato product intake and estimated lycopene intake. Conditional logistic regression to estimate odds ratios adjusted for confounders.
In Vitro Study of Tomato Extract Fractions on Endothelial Cell Function and Oxidative Stress
Human umbilical vein endothelial cells (HUVECs) treated with lycopene-only, whole tomato extract, tomato extract devoid of lycopene, and individual non-lycopene compounds (e.g., chlorogenic acid, quercetin). Measure nitric oxide production, endothelial nitric oxide synthase (eNOS) activation, and protection against oxidative stress (e.g., H2O2-induced cell damage). Outcome: comparison of efficacy across treatments.
