Food Therapy: Coffee and Coffee Caffeine in Inhibition of Genotoxicity

By Kyle J. Norton


Coffee and coffee caffeine may have a profound and positive effect in reduced risk of genotoxicity, caused by environment toxins, a coffee production company opinionated.

Coffee, a popular and social beverage all over the world, particular in the West, is a drink made from roasted bean from the Coffea plant, native to tropical Africa and Madagascar.

In rat liver and primary hepatocytes, regular intake of coffee daily illustrated a enormous effect in cellular antioxidant defenses through regulating exhibited enzymes involved mRNA and protein expression.

The study also suggested that coffee and coffee caffeine through expression of detoxifying enzymes GSTs and AKR(in cellular detoxification) also demonstrated a significant activity in reduced risk of genotoxicity and cytotoxicity caused by injection of aflatoxin B1 (AFB1).

Dr. Cavin C, ther lead author said, " the coffee-mediated stimulation of the Nrf2-ARE pathway resulting in increased endogenous defense mechanisms against electrophilic but also oxidative insults further support that coffee may be associated with a protection against various types of chemical stresses".
(Please note that Nrf2-ARE pathway is an indicator and modulator of oxidative stress)

Other, in the evaluated L5178Y mouse lymphoma cell line to assess modulatory effects of coffee against genotoxicity induced by N-methyl-N-nitro-N-nitrosoguanidine (MNNG), researchers found that
1. 3 doses of instant coffee caffeine injection displayed a decrease in genotoxicity following co-treatment of mouse lymphoma cells.
2. Coffee caffeine pre-treatment or co-treatment exhibited significant antigenotoxic effects against MNNG(an environmental carcinogen that causes DNA mutation) expression.
3. Both caffeinated and decaffeinated instant coffee demonstrated a similar effect against genotoxicity in the experiment samples.

Dr. Abraham SK, the lead authors said, " Results from three or five independent experiments demonstrated significant protective effects of caffeinated instant coffee against MNNG-induced DNA damage in the comet assay, mutation at the Tk locus and chromosomal damage in the cytokinesis-block micronucleus test".

In support of the above analysis, the Swiss Federal Institute of Technology (ETH), in the study of  protective effects of coffee against somatic mutation and mitotic recombination induced by chemo drugs, cyclophosphamide (CPH)(, mitomycin C (MMC) and urethane (URE), using standard (ST) and high bioactivation (HB) crosses of the wing spot test in Drosophila melanogaster assays, suggested that in dose depending, coffee injection showed a strong effect in the genotoxicity of URE in the ST and the genetically susceptible HB cross as well as the genotoxicity caused by MMC application.

Dr. Abraham SK, the lead researcher said, "The magnitude of the protective effects of coffee against these three genotoxins was independent of the genotype of the larvae used for treatment, that is it was independent of the bioactivation capacity of these larvae".

The collective information showed a definitive support in used of coffee and coffee caffeine as functional food in reduced risk against genotoxic expression, including side effects of chemo medicine used in treatment of multi types of cancers.
