The last decade is characterized by an explosive growth of interest in the impact of red beet root on human health. In the review information on the chemical composition and nutritional value of red beet as well as pigments biological effects are presented. Analyzed reports abound on antioxidant, anti-inflammatory and chemo-preventive Beta vulgaris phytochemical activity, its impact on gastrointestinal and cardiovascular system as well as endurance exercise performance. In details the red beet nitrates bioconversion and its role in blood pressure regulation have been described. The first information on red beetroot juice impact on iron metabolism is summarized. Beet processing methods, which led to the appearance of a lot of conventional red beet products, functional food, and dietary supplements, are described. Fractionated red beetroot juice on the molecular mass basis is prospective for senile sarcopenia as well as senile cognitive decline and Alzheimer's disease prevention. The aim of this review is to discuss red beetroot biological effects and new trends in the studies, targeted on development of new functional food products as well as medicines.
Iron deficiency is one of the leading risk factors for disability and death worldwide. Targeted iron supplementation with pharmaceuticals is widely used, but oral iron salt ingestion often causes side effects-nausea, vomiting, abdominal pain. The present study demonstrated that red beetroot juice (RBRJ) contains a compound or compound complex with the ability to specifically stimulate duodenal iron absorption, shown in experiments in vitro, in situ and in vivo. The effect does not depend on juice sugar and ascorbic acid concentration. Fractionated RBRJ impact on iron absorption is dose dependent. This phenomenon is described for the first time.
The high toxicity, bioaccumulative and increased distribution of cadmium (Cd) in the environment, makes it the most dangerous to any biological system, including immune system in human and animals. The effect of dietary intake of Cd (8.25 mg per kg) on accumulation and distribution of this heavy metal in various tissues, and functional changes in organs of immunity (thymus, bursa of Fabricius, spleen) in 35-day-old broiler cockerels were investigated, using biochemical and immunological methods. Significant increases in the Cd concentration both in central immunocompetent organs (thymus, bursa of Fabricius) and peripheral (spleen) were established. Excessive tissue level of Cd induced the prooxidative effect of this heavy metal in the organs. It was manifested in an increase of cell membrane lipid peroxidation (the enhanced malondialdehyde (MDA) concentration) in immune system organs. The oxidative stress resulted in immunocompetent cell damage. The fall of vital dye absorptive ability of immunocyte indicated the increase in the injured cell number. This harmful effect is in accordance with T-and B (C3)-population prominent depletion, organ relative mass reduction, and growth retardation in chicks, and was established as a result of dietary Cd loading for 5 weeks of the experiment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
