Researchers in Nanjing Institute of Environmental Science (China) A study that highlighted the complex effect of alcohol consumption on the bioavailability of arsenic and how it accumulates in tissues, indicating that Alcohol alters the gut microbiome and intestinal barrierswhich affects the distribution of arsenic throughout the body, reducing toxicity in vital organs.
Arsenic is ubiquitous in the environment and is a carcinogen Level 1 to humans, posing serious health risks through exposure to food, water and soil. Understanding the factors that affect how it is absorbed and stored in the body is key to assessing health risks.
“Although alcohol consumption is common across the world and known for its various health effects,… Its interaction with how arsenic is absorbed and its resulting toxicity had been largely overlooked until this recent studyResearchers say.
In this pioneering study published in Environmental environment and healthResearchers looked at how alcohol affects the body's processing of arsenic, a widespread environmental toxin. The mice were fed an arsenate-rich diet and daily amounts of Chinese liquor, to mimic human alcohol intake. Curiously, Although alcohol increases the absorption of arsenic in the intestine, it surprisingly reduces its accumulation in vital organs.
This unexpected effect is due to the damage alcohol causes to the intestinal barriers and changes in intestinal bacteria, which increases the entry of arsenic into the bloodstream. Importantly, alcohol also increases kidney filtration and reduces antidiuretic hormone levels, resulting in more arsenic being eliminated through the urine. Essentially, alcohol accelerates the release of arsenic from the body, reducing its harmful potential.
They added: “This study reveals the complex interplay between common substances and their unexpected health effects, providing a new angle on arsenic toxicity and the impact of alcohol.”
Alcohol intake damaged the intestinal tight junction and caused increased absorption of arsenic through cellular intestinal pathways. Alcohol intake reduces glomerular tight junctions and increases glomerular filtration of arsenic; The diuretic function of alcohol consumption also contributed to reducing arsenic accumulation in tissues.
“Due to widespread exposure to both substances, It is essential to understand how they interact within the body to better predict and mitigate health risksDr. Hongbo Li, corresponding author, stresses the importance of understanding the role of alcohol in arsenic bioavailability.
The results suggest that although alcohol consumption can increase the amount of arsenic absorbed, It also improves its elimination from the body, which may reduce its accumulation in tissues and reduce some of the risks of poisoning. This information is especially important for groups exposed to both arsenic and alcohol.Because it provides a detailed presentation of risk factors and their interactions.
