What the research says
2 studies reviewedSupporting (1)
Systematic Review With Meta-AnalysisMeta-analysis2019
This study looked at many other studies and found that people who eat a lot of tomatoes or have high levels of lycopene in their blood are less likely to have heart attacks, strokes, or die from heart disease, which supports the idea that eating tomato products a few times a week is good for your heart.

Systematic Review With Meta-AnalysisMeta-analysis2023
While eating tomatoes might lower one sign of cell damage, a large analysis showed that it did not improve important heart health measures like cholesterol, blood pressure, or blood sugar, so it does not prove that tomatoes support heart health.
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 lycopene, a powerful antioxidant. Antioxidants protect your cells from damage caused by unstable molecules called free radicals. By neutralizing free radicals, lycopene reduces damage to blood vessels, keeping them healthy and flexible. This helps your heart and blood vessels work better, lowering the risk of heart disease.

Eating tomato-based products a few times per week improves heart and blood vessel health.
Mechanism
2 studiesTomatoes have a substance called lycopene that acts like a shield for your cells. It stops harmful molecules from hurting your blood vessels. By protecting your blood vessels, lycopene helps keep your heart healthy, though it may not directly lower cholesterol or blood pressure.
Tomatoes contain lycopene, a powerful antioxidant. Antioxidants protect your cells from damage caused by unstable molecules called free radicals. By neutralizing free radicals, lycopene reduces damage to blood vessels, keeping them healthy and flexible. This helps your heart and blood vessels work better, lowering the risk of heart disease.
Lycopene from tomatoes is absorbed and accumulates in tissues.
Lycopene scavenges reactive oxygen species, reducing oxidative stress in the bloodstream and vessel walls.
Reduced oxidative stress decreases oxidation of low-density lipoprotein (LDL) cholesterol and prevents damage to endothelial cells lining blood vessels.
Preserved endothelial function and reduced inflammation lower the development of atherosclerotic plaques and thrombotic events.

Lycopene and tomato and risk of cardiovascular diseases: A systematic review and meta-analysis of epidemiological evidence
This study looked at many other studies and found that people who eat a lot of tomatoes or have high levels of lycopene in their blood are less likely to have heart attacks, strokes, or die from heart disease, which supports the idea that eating tomato products a few times a week is good for your heart.

The effects of lycopene and tomato consumption on cardiovascular risk factors in adults: a Grade assessment systematic review and meta-analysis.
While eating tomatoes might lower one sign of cell damage, a large analysis showed that it did not improve important heart health measures like cholesterol, blood pressure, or blood sugar, so it does not prove that tomatoes support heart health.

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 and Meta-Analysis of Randomized Controlled Trials on Tomato Product Consumption and Cardiovascular Health
A systematic review of RCTs comparing dietary patterns with or without tomato-based products (e.g., tomato sauce, juice, whole tomatoes) for at least 12 weeks, measuring cardiovascular outcomes such as blood pressure, lipid profiles, and inflammatory markers.
Randomized Controlled Trial of Daily Tomato Product Consumption on Blood Pressure and Lipid Profiles in Adults
A parallel-group, double-blind, placebo-controlled trial randomizing 200 adults (ages 40-70) to consume either 200g of tomato-based products (e.g., tomato juice) or a placebo drink daily for 12 weeks. Primary outcomes: systolic/diastolic blood pressure, LDL cholesterol, hs-CRP. Secondary outcomes: endothelial function via flow-mediated dilation.
Prospective Cohort Study on Long-Term Tomato Consumption and Cardiovascular Disease Incidence
A prospective cohort of 50,000 adults free of CVD at baseline, followed for 10 years with dietary assessments (FFQ) every 2-4 years, comparing those who consume tomato products >=3 times/week vs <1 time/week, with outcome of incident myocardial infarction, stroke, or cardiovascular death, adjusting for known confounders (age, smoking, physical activity, other diet).
Cross-Sectional Analysis of Tomato Consumption and Cardiovascular Risk Markers in a Population-Based Sample
A population-based survey of 5,000 adults, assessing tomato product consumption via validated food frequency questionnaire and measuring blood pressure, fasting lipids, and inflammatory markers in a single visit. Statistical analysis adjusting for age, sex, BMI, and other dietary factors.
