Lycopene is more bioavailable from tomato paste than from fresh tomatoes.
Lycopene bioavailability from a single dose of fresh tomatoes or tomato paste (23 mg lycopene) ingested together with 15 g corn oil was compared by analyzing carotenoid concentrations in the chylomicron fraction. The lycopene isomer pattern was the same in both fresh tomatoes and tomato paste. The triacylglycerol response in chylomicrons was not significantly different after both treatments. In...
متن کاملLycopene from heat-induced cis-isomer-rich tomato sauce is more bioavailable than from all-trans-rich tomato sauce in human subjects.
Lycopene is present mainly as cis-isomers in human serum and tissues whereas all-trans-lycopene predominates in tomato products, suggesting that all-trans-lycopene is isomerised in the body or is less bioavailable. The objectives of the present study were to develop processing conditions for tomatoes to obtain products with different cis-trans-lycopene isomer distribution and to assess their bi...
متن کاملCarotenoids are more bioavailable from papaya than from tomato and carrot in humans: a randomised cross-over study.
Carrot, tomato and papaya represent important dietary sources of β-carotene and lycopene. The main objective of the present study was to compare the bioavailability of carotenoids from these food sources in healthy human subjects. A total of sixteen participants were recruited for a randomised cross-over study. Test meals containing raw carrots, tomatoes and papayas were adjusted to deliver an ...
متن کاملp63 is more sensitive and specific than 34βE12 to differentiate adenocarcinoma of prostate from cancer mimickers
Objective(s): Prostate cancer is the world’s leading cause of cancer and the second cause of cancer-related death in men after lung cancer. Differentiation of prostate adenocarcinoma from benign prostate lesions and hyperplasia sometimes cannot be done on the basis of morphologic findings. Considering the fact that in the prostate adenocarcinoma there is no basal cell layer, basal cell markers ...
متن کاملLycopene Monograph
T o m a t o products, including ketchup, tomato juice, and pizza sauce, are the richest sources of lycopene in the U.S. diet, accounting for greater than 80 percent of the total lycopene intake of Americans. In addition to tomatoes (Lycopersicon esculentum) and tomato-based products, lycopene is also found in watermelon, papaya, pink grapefruit, and pink guava. Lycopene from both processed and ...
