Taking B Vitamins Helps Reverse DNA Damage From Air Pollution – Including The Most Dangerous Kinds!
A new study by researchers at Columbia University’s Mailman School of Public Health showed that B vitamins may play a critical role in reducing the impact of the most adverse type of air pollution.
In the first study of its kind, a team of international researchers looked at the damage caused by one of the pollutants that has the most severe impact on health: PM2.5.
The team found that something as simple as a daily vitamin B supplement could potentially reduce the impact of the tiny particles on the human body, although they stressed that research was in its early stages and the sample size was small.
Particulate matter, or PM, is a type of air pollutant consisting of small particles of different sizes — from tiny molecular clusters to dust or pollen that we can see. PM2.5 has a diameter of fewer than 2.5 micrometers, about 30 times smaller than a human hair.
“These particles are so small they can go into our respiratory system,” Chak K. Chan, professor of Atmospheric Environment at the School of Energy and Environment, at Hong Kong’s City University told CNN. “They can go deep into our lungs.”
Once the particles are inhaled they can result in lung and systemic inflammation and stress, experts say. And scientists suspect exposure to PM2.5 can cause “epigenetic” changes to our cells — disturbances or mutations that can damage our health.
According to the WHO, 92% of the world’s population lives in places where the PM2.5 level exceeds the recommended threshold.
Last December, air quality in China hit its worst with airborne pollutants exceeding 100 times the safe limit in many regions!
However, how exactly these particles make people unwell is currently not fully understood, Andrea Baccarelli, chair of Environmental Health Sciences at Columbia University’s Mailman School of Public Health, and one of the authors of the study, said in a statement.
“The lack of preventative options at the individual level adds complexity to tackling this major public health challenge,” she said.
The study also involved researchers at Harvard’s T. H. Chan School of Public Health.
How the study was conducted
To take part in the intervention, volunteers were required to be healthy non-smokers, 18 to 60 years old, who were not taking any medicines or other vitamin supplements.
10 volunteers were initially exposed to clean air and given a placebo to check their baseline responses.
The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Toronto, where an estimated 1,000 cars pass every hour.
The bad air was delivered to the volunteers through an “oxygen type” face mask.
The experiment was then repeated, with each volunteer taking a B vitamin supplement daily — made up of 2.5 mg of folic acid, 50 mg of vitamin B6, and 1 mg of vitamin B12.
Vitamin B12 is for healthy nerve function and a healthy metabolism.
Vitamin B1 (thiamin), Vitamin B2 (riboflavin), Vitamin B3 (niacin), Vitamin B5 (pantothenic Acid), Vitamin B6 (pyridoxine), Vitamin B7 (biotin), Vitamin B9 (folate), and Vitamin B12 (cobalamin) are all critical for a healthy body, including everything from metabolism and energy, to nerve function, mental focus, and for healthy digestion.
Here’s where to get them if you’re eating a plant-based diet.
The results are promising
The researchers found that four weeks of B vitamin supplements reduced the damage of PM2.5 exposure by 28-76%.
The results highlight how prevention at an individual level could be used to fight the adverse effects of PM2.5, the researchers said.
“Future studies, especially in heavily polluted areas, are urgently needed to validate our findings and ultimately develop preventive interventions using B vitamins to contain the health effects of air pollution,” said Baccarelli.
“While emission control and regulation is the backbone of prevention, high exposures are, unfortunately, the rule still in many megacities throughout the world,” she said.
Experts agree that while we must do whatever we can to protect ourselves against pollution, central regulation is critical to ensure long term health.
“Regulation goes together with implementation,” said Chan, adding that while people should use masks, air purifiers or any other emerging methods to protect themselves, ultimately, in his view, it’s the responsibility of governments to protect people’s health through maintaining air quality.
“A lot of us don’t really have a choice to pick what type of air we breathe in. Air is the basic resource to support human life — this is something that we not have any option about.”
