Tomatoes are an important part of the diet. Lycopene, the predominant carotenoid in tomatoes, is hypothesised to mainly mediate the health benefits of tomato products. Anticancer activity of tomato products and lycopene has been suggested by numerous studies. The aim of the present study was to investigate the effect of ingestion of three different tomato-based foodstuffs on plasma contents of lycopene, tocopherols and ascorbic acid. Because isomers of lycopene may have different biological…

Influence of olive oil on carotenoid absorption from tomato juice and effects on postprandial lipemia.
Tangerine tomatoes increase total and tetra-cis-lycopene isomer concentrations more than red tomatoes in healthy adult humans
TLDR
The results suggest that total lycopene concentrations can be increased by substituting tetra-cis-lycopene-rich tangerine tomatoes for common red tomatoes in the diet.
Tomato and Tomato Byproducts. Human Health Benefits of Lycopene and Its Application to Meat Products: A Review
TLDR
The aim of this review is to present an overview of the functional and physiological properties of the principal bioactive compound present in tomato and tomato byproducts, lycopene, its addition to meat, and meat products.
Consumption of canned citrus fruit meals increases human plasma β-cryptoxanthin concentration, whereas lycopene and β-carotene concentrations did not change in healthy adults.
The proportion of lycopene isomers in human plasma is modulated by lycopene isomer profile in the meal but not by lycopene preparation
TLDR
Results show that the tomato preparation has no impact on the lycopene isomerisation occurring during absorption in human, indicating that the 9-Z and 13-Z isomers were less absorbed or were converted into 5-E and (all-E) isomers.
In vitro antioxidant capacity of tomato products: Relationships with their lycopene, phytoene, phytofluene and alpha-tocopherol contents, evaluation of interactions and correlation with reflectance measurements
Bioavailability of Phytochemical Constituents From a Novel Soy Fortified Lycopene Rich Tomato Juice Developed for Targeted Cancer Prevention Trials
TLDR
A well-characterized soy-fortified tomato juice can be produced in large scale for multiinstitutional long-term cancer prevention trials and showed excellent compliance with no toxicity, while demonstrating absorption of biologically active phytochemicals.
Lycopene from heat-induced cis-isomer-rich tomato sauce is more bioavailable than from all-trans-rich tomato sauce in human subjects
TLDR
Significant lycopene bioavailability from cis-lycopene-rich tomato sauce is demonstrated and highlights the importance of considering isomer-distribution for lycopenes bioavailability.
Processing tangerine tomatoes: effects on lycopene-isomer concentrations and profile.
TLDR
Processing of tangerine tomatoes resulted in a large decrease in tetra-cis lycopene concentration accompanied by increases in trans- and other cis-lycopene isomers, which are more bioavailable than the all-trans isomers and thus more efficiently absorbed.
Influence of lycopene and vitamin C from tomato juice on biomarkers of oxidative stress and inflammation
TLDR
Any beneficial effects of tomato consumption for human health cannot be attributed only to lycopene and, as the additional supplementation with ascorbic acid indicates, a variety of antioxidants might be needed to optimize protection against chronic diseases.

Chronic ingestion of lycopene-rich tomato juice or lycopene supplements significantly increases plasma concentrations of lycopene and related tomato carotenoids in humans.
TLDR
Lycopene appears to be equally bioavailable from tomato juice and the supplements used in this study, and concentrations of plasma lycopene and other carotenoids with potential for enhancing human health can be increased by ingestion of realistic amounts of tomato juice.
Carotenoid bioavailability in humans from tomatoes processed in different ways determined from the carotenoid response in the triglyceride-rich lipoprotein fraction of plasma after a single consumption and in plasma after four days of consumption.
TLDR
It is concluded that the intactness of the cellular matrix of tomatoes determines theBioavailability of carotenoids and that matrix disruption by mechanical homogenization and/or heat treatment enhances the bioavailability.
Changes in contents of carotenoids and vitamin E during tomato processing.
The aim of this study was to investigate the effect of different types of tomato processing on contents of lycopene, beta-carotene, and alpha-tocopherol. Samples of tomato sauce, tomato soup, baked…
Changes in Plasma and Oral Mucosal Lycopene Isomer Concentrations in Healthy Adults Consuming Standard Servings of Processed Tomato Products
TLDR
It is demonstrated that plasma lycopene decreases by 50% after approximately 2 wk on a Lycopene-free diet with a decrease in the ratio of all-trans compared with cis isomers with greater insight into the potential health benefits suggested by epidemiological studies and laboratory investigations.
Intestinal absorption of lycopene from different matrices and interactions to other carotenoids, the lipid status, and the antioxidant capacity of human plasma
TLDR
The plasma lycopene increased significantly, while it remained unchanged during intake of tomatoes, while other plasma carotenoids such as β-carotene and β-cryptoxanthin decreased significantly, whereas lutein and zeaxanthin remained unchanged.
The consumption of processed tomato products enhances plasma lycopene concentrations in association with a reduced lipoprotein sensitivity to oxidative damage.
TLDR
It is shown that lycopene concentrations and isomer patterns change rapidly with variation in dietary intake, and 15 d of tomato product consumption significantly enhanced the protection of lipoproteins to ex vivo oxidative stress.
A food-based formulation provides lycopene with the same bioavailability to humans as that from tomato paste.
TLDR
The lactolycopene formulation and tomato paste exhibited similar lycopene bioavailability in plasma and buccal mucosa cells in humans and the precursor of Lycopene, phytofluene, was better absorbed than lycopenes itself.
Isomerization of dietary lycopene during assimilation and transport in plasma
TLDR
Following a diet containing cooked tomatoes over three consecutive 7-day periods, little change in the carotenoid levels in plasma lipoproteins occurred, but a diet supplemented with concentrated tomato purée over a 2 week period caused a significant increase in lycopene levels in Plasma, showing that the lycopenes within intact cells is less bioavailable than that from processed tissue.
Lycopene is more bioavailable from tomato paste than from fresh tomatoes.
TLDR
In humans, the bioavailability of lycopene is greater from tomato paste than from fresh tomatoes, and only the AUC response for the cis-isomers was significantly higher after ingestion of tomato paste.

TLDR
Determination of the degree of lycopene isomerization during processing would provide a measure of the potential health benefits of tomato-based foods, and further research on the bioavalability, pharmacology, biochemistry, and physiology must be done to reveal the mechanism of lyCopene in human diet.
