Adding avocado to a salsa meal helped healthy adults absorb about 4.4 times more lycopene, a relative increase, than salsa alone.
See the scientific wording
In healthy adults, adding 150 g of avocado to a 300 g salsa meal increases lycopene absorption by 4.4 times RELATIVE compared with eating the salsa alone, as measured by the area under the plasma triacylglycerol-rich lipoprotein concentration-time curve over 9.5 hours; this corresponds to an ABSOLUTE increase in median lycopene AUC from 18.97 to 68.97 nmol·h/L (absolute increase 50.00 nmol·h/L).

What the research says
1 study reviewedSupporting (1)
Cohort StudyHuman2005
In a small human study, eating salsa with avocado led people to absorb about 4.4 times more lycopene and 2.6 times more beta-carotene than eating salsa alone. The study's numbers match the claim exactly, so the claim is supported.

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.
When you eat salsa, the plant colors in it (like lycopene and beta-carotene) are hard for the body to take in on their own. Adding avocado brings fat. The fat helps break the plant colors into tiny droplets in the gut. These droplets let the plant colors pass into the cells lining the gut. Inside those cells, the fat also helps wrap the plant colors into little fat carriers. Those carriers are released into the blood, so more plant colors show up in the blood over the next several hours.

Adding avocado to a salsa meal helped healthy adults absorb about 4.4 times more lycopene, a relative increase, than salsa alone.
Mechanism
1 studyThe body absorbs the plant colors in salsa much better when fat is present. Avocado supplies that fat. The fat helps the gut turn the plant colors into tiny droplets and then pack them into little fat carriers that go into the blood. That is why adding avocado makes more lycopene and beta-carotene show up in the blood.

A carotenoid-rich meal consumed together with a lipid source delivers both lipophilic carotenoids and dietary triglycerides into the gastrointestinal lumen.
Dietary lipids undergo digestion by gastric and pancreatic lipases and are emulsified by bile salts, forming mixed micelles in the small intestine that solubilize lycopene and beta-carotene.
Solubilized carotenoids partition into mixed micelles and are absorbed by intestinal enterocytes.
Inside enterocytes, long-chain fatty acids, particularly monounsaturated oleic acid from avocado, enable the esterification and packaging of carotenoids into chylomicrons.
Carotenoid-laden chylomicrons are secreted into the lymphatic system and enter the systemic circulation as triacylglycerol-rich lipoproteins (TRL).
The increased appearance of carotenoids in the plasma TRL fraction over 9.5 hours, measured as baseline-corrected area under the curve, reflects enhanced intestinal absorption of lycopene and beta-carotene.
