Carrots may have a profound and positive effect in reduced oxidative stress in the induction of related chronic diseases, including atherosclerosis, cancers, diabetes, rheumatoid arthritis, post-ischemic perfusion injury, myocardial infarction, cardiovascular diseases,... and stroke, some scientists suggested.
Oxidative stress is the indication of overexpression free radicals in the body due to depletion of antioxidants produced by the host tissue.
According to the Department of Biotechnology, M. J. College, "Overproduction of free radicals can cause oxidative damage to biomolecules, (lipids, proteins, DNA), eventually leading to many chronic diseases".
The studies of carrots in reduced overproduction of reactive oxygen species in facilitated oxidative stress were carried out by several respectable institutes and the results were published online medical literature.
Carrot, a root vegetable with an orange color is a subspecies of Daucus carota, belongings to the family Apiaceae, native to Asian and Europe.
In the investigation of the relation of dietary supplementation with lycopene (LYC), a major active biochemical compound found in carrot, on age-induced cognitive impairment, and the potential underlying mechanisms, using the behavioral tests, researchers at Northwest A&F University, researchers found that chronic injection of LYC exerts a potential effect in alleviated age-associated memory loss and cognitive defects through several mechanisms
Application of lycopene improved antioxidant produced by the host body in countering to the overexpression of free radicals, including glutathione, catalase, and superoxide dismutase activities and the levels of antioxidant-enzyme.
Treatment of the phytochemical displayed a strong activity in reversed age-associated neuronal damage and synaptic dysfunctions in the brain, through inhibited the levels of malondialdehyde (MDA) levels in associated to oxidative stress.
Malondialdehyde (MDA) levels are considered as oxidative maker used in the treatment of cancers and other oxidative related diseases.
Interestingly, researchers also indicated that chronic injection of bioactive lycopene lowers the levels of the accumulation of Aβ1-42 in the brains in aged CD-1 mice model.
Evidence findings suggested that Aβ-induced oxidative stress may place the majority of the causative effect of increased cellular oxidative stress upon oligomeric Aβ(1–42).
Furthermore, LYC supplementation also significantly reduced age-associated neuroinflammation caused by overexpression of free radicals in the activation of proinflammatory cytokines by inhibiting microgliosis (Iba-1) in response to damage to the central nervous system (CNS) and related inflammatory chemicals mediators.
These results overwhelmingly suggested that lycopene injection processes a strong effect in reduced risk and treatment of diseases associated with overproduction of ROS, through re-balancing the ratio of antioxidant and free radicals in the host body.
Moreover, in d-galactose-induced CD-1 male mice cognitive impairments, chronic LYC supplementation (50 mg/kg body weight per day) demonstrated a significant activity in inhibition of oxidative stress-induced cognitive defects.
Injection of lycopene also ameliorated histopathological damage and restored brain-derived neurotrophic factor (BDNF) levels in the hippocampus of mice. These findings reaffirms the conclusion of the Northwest A&F University study.
LYC treatment in an animal model also increased antioxidant of the host by activating the mRNA expressions of antioxidant enzymes HO-1 and NQO-1, and inhibited the oxidative stress in the induction of inflammatory cytokines IL-1β and TNF-α in host hippocampus.
More precisely, LYC attenuated neuronal oxidative damage through activation of Nrf2 signaling in increased levels of anti-inflammatory cytokines and inactivation of NF-κB translocation in signaling pro-inflammatory expression.
Dr. Zhao B, the lead scientist, after taking into account of co and confounders said, " LYC could ameliorate oxidative stress-induced neuroinflammation and cognitive impairment possibly via mediating Nrf2/NF-κB transcriptional pathway".
The findings indicated that carrot with major active compound lycopene may be considered as functional foods in prevention and treatment of oxidative related diseases by restoring the ratio of reactive oxygen species and levels of antioxidant in the body.
