Lycopene (a nutrient found in tomatoes) can help reduce the fatty buildup in your arteries, and eating lycopene-rich foods is better for your heart than taking lycopene pills.
See the scientific wording
Lycopene supplementation is capable of reversing arterial plaque; however, dietary intake of lycopene-containing foods provides stronger cardiovascular benefits than supplementation.

Cohort StudyAnimal2021
Lycopene pills helped mice have less fat buildup in their arteries, but the study didn't check if it can remove already-existing plaque or if tomato foods work better than pills.
Contradicting (1)
Randomized Controlled TrialHuman2012
The study found that eating lots of tomatoes or taking lycopene pills didn't improve heart health markers, so it doesn't support the idea that lycopene can reduce plaque in arteries.
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.
Lycopene is a nutrient in foods like tomatoes. It works as an antioxidant, meaning it helps stop free radicals from damaging blood vessels. This damage causes swelling and stiffness in the arteries. By reducing free radicals, lycopene lowers swelling and helps arteries stay flexible. It also lowers bad cholesterol. Together, these effects help clear out plaque that builds up on artery walls. Eating lycopene in whole foods gives the body a better supply than taking pills, so the benefits are stronger.

Mechanism
2 studiesLycopene helps the body by cleaning up harmful particles in the blood, which reduces swelling and keeps blood vessels flexible. It also helps lower bad cholesterol. These effects work together to shrink fatty deposits in the arteries. Eating lycopene in whole foods gives the body a better supply than taking pills, so the benefits are stronger. The effects have not been observed in humans yet, but the body's natural processes suggest this is how it works.

Lycopene from whole foods is absorbed more efficiently in the gut than from supplements, leading to higher concentrations in the bloodstream and tissues.
In the bloodstream, lycopene neutralizes reactive oxygen species, reducing oxidative stress.
Lower oxidative stress suppresses pro-inflammatory signaling, reducing the levels of inflammatory cytokines.
Reduced inflammation improves endothelial function, increasing nitric oxide production and decreasing arterial stiffness.
Lycopene modulates hepatic lipid metabolism, lowering LDL cholesterol and triglycerides.
These combined effects stabilize and regress atherosclerotic plaque.

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 & Meta-Analysis of RCTs on Lycopene Supplementation and Arterial Plaque Reversal and Comparison of Dietary vs Supplement Sources
A systematic review and meta-analysis that includes RCTs and controlled trials comparing lycopene supplementation against placebo for plaque regression (measured by imaging such as carotid intima-media thickness or coronary calcium score) and trials comparing lycopene-rich diets against supplements for cardiovascular outcomes. It should pool data on plaque reversal and cardiovascular events.
Double-Blind Randomized Controlled Trial of Lycopene Supplementation (vs Placebo) on Carotid Artery Plaque Regression in Adults
A double-blind, placebo-controlled RCT with adults (e.g., aged 45-75) at high cardiovascular risk, randomized to receive a standardized lycopene supplement or placebo daily for 12-24 months. The primary outcome is change in carotid intima-media thickness (CIMT) or plaque volume measured by MRI or ultrasound. Secondary outcomes include blood pressure, lipid profile, and inflammatory markers.
Prospective Cohort Study of Dietary Lycopene Intake and Cardiovascular Events and Plaque Progression in Middle-Aged Adults
A prospective cohort study enrolling a large population of healthy middle-aged adults (e.g., 40-70 years) with no baseline cardiovascular disease. Dietary lycopene intake is assessed via food frequency questionnaires and serum lycopene levels at baseline. Participants are followed for 5-10 years, with periodic imaging (e.g., coronary artery calcium score or carotid ultrasound) to track plaque changes and recording of cardiovascular events such as heart attack or stroke.
Cross-Sectional Study of Serum Lycopene Levels and Arterial Plaque Burden in Adults
A cross-sectional study in a diverse adult population (e.g., aged 40-80) undergoing cardiovascular screening. Serum lycopene levels are measured, and arterial plaque burden is assessed using imaging (e.g., coronary CT angiography or carotid ultrasound). Multivariable regression is used to adjust for confounders such as age, sex, BMI, smoking, and dietary patterns.
In Vitro Study of Lycopene's Effect on Foam Cell Formation and Plaque Regression in Human Aortic Cells
In vitro experiments using human aortic smooth muscle cells or macrophages cultured in atherosclerotic-like conditions. Cells are treated with lycopene at physiologically relevant concentrations, and outcomes include lipid uptake, foam cell formation, cholesterol efflux, and expression of inflammatory markers. The study could also use tissue-engineered arterial models to test plaque regression.
