A review of vitamin A equivalency of β-carotene in various food matrices for human consumption.
Vitamin A equivalency of β-carotene (VEB) is defined as the amount of ingested β-carotene in μg that is absorbed and converted into 1 μg retinol (vitamin A) in the human body. The objective of the present review was to discuss the different estimates for VEB in various types of dietary food matrices. Different methods are discussed such as mass balance, dose-response and isotopic labelling. The...
متن کاملRetinol and ?-Carotene inhibit PTZ-induced kindling in mice
Vitamin A and its derivatives have recently reported to be implicated in synaptic plasticity. The possible effect of vitamin A and its precursor, ?-carotene, on seizure acquisition was tested in PTZ kindling model of epilepsy. Vitamin A and ?-carotene were tested for their ability to 1) suppress seizures (clonic and tonic) and lethality induced by PTZ in PTZ-kindled mice (anticonvulsant effect)...

متن کاملDietary Carotenoids, Serum β-Carotene, and Retinol and Risk of Lung Cancer in the Alpha-Tocopherol, Beta-Carotene Cohort Study
Findings from several β-carotene supplementation trials were unexpected and conflicted with most observational studies. Carotenoids other than β-carotene are found in a variety of fruits and vegetables and may play a role in this important malignancy, but previous findings regarding the five major carotenoids are inconsistent. The authors analyzed the associations between dietary β-carotene, β-...
متن کاملRetinol, β-carotene and oxidative stress in systemic inflammatory response syndrome.
OBJECTIVE patients suffering systemic inflammatory response syndrome (SIRS) constitute a group susceptible to elevated levels of oxidative stress. This study's aim is to evaluate the state of oxidative stress and levels of serum retinol and β-carotene in these patients. METHODS forty-six patients were divided into 2 groups: those those without diet (G1; n=18) and those with enteral nutritiona...
