9 ways to save your brain from disease-causing particles

We know that exposure to small particulate matter from air pollution, especially from vehicle exhaust, changes the brain.

Small particulate matter, those tiny particles of metal and other contaminants that live unseen in heavily polluted air, enters your brain through your nose and triggers an inflammatory response.

Brain inflammation plays a big role in Alzheimer’s, so one more inflammation-causing agent could be the tipping point that sends your cognitive health into a downward spiral.

A study from researchers at the University of Southern California found that older women who live in areas where particulate matter air pollution is higher than the U.S. Environmental Protection Agency’s standard are 92 percent more likely to develop Alzheimer’s or dementia.

Now, we also know that pollution is linked to Parkinson’s and motor neuron disease and that the damage begins a lot earlier in life than we’d thought…    

Air pollution lodges in the brain at an early age

Mexico City, a city of over 20 million people, has been plagued by dangerous levels of air pollution for decades. I remember a trip there some 40 years ago, and even then, people were wearing masks on high-pollution days.

Researchers from Lancaster University in England examined the brainstems of 186 young Mexico City residents between the ages of 11 months and 27 years. They found markers (predictors) not only of Alzheimer’s disease but also of Parkinson’s and motor neuron disease (MND).

“Not only did the brainstems of the young people in the study show the ‘neuropathological hallmarks’ of Alzheimer’s, Parkinson’s and MND,” says Professor Barbara Maher of Lancaster University, “they also had high concentrations of iron-, aluminum-, and titanium-rich nanoparticles in the brainstem — specifically in the substantia nigra and the cerebellum.”

Brain changes caused by nanoparticles

The ‘“neuropathological hallmarks” that Professor Maher mentions include nerve cell growths, as well as plaques and tangles caused by misfolded proteins in the brain, a hallmark of Alzheimer’s disease. These were found even in infants as young as 11 months old.

And it appears that these tiny metallic particles can reach the brain stem either through inhalation or by swallowing. They are associated in particular with damage to the substantia nigra, an area of the brainstem in charge of initiating and inhibiting our motor neurons, thus controlling our ability to execute movements smoothly.

Not surprisingly, damage to the substantia nigra is directly linked with the development of Parkinson’s disease later in life.

How to protect your brain from pollution

Professor Maher says, “Different people will have different levels of vulnerability to such particulate exposure, but our new findings indicate that what air pollutants you are exposed to, what you are inhaling and swallowing, are really significant in development of neurological damage.”

So, how do you become one of the less vulnerable people? How do you protect your children and grandchildren from developing these debilitating conditions when they grow up?

Here are 9 good first steps:

  1. Eat broccoli sprouts and other foods that help your liver do the work of detoxifying your body.
  2. Eat fish, particularly those with high omega-3 content, like rainbow trout, wild Alaskan salmon, sardines and albacore tuna. Omega-3 fatty acids have been shown to fight brain inflammation and prevent some of the brain damage caused by neurotoxins like lead and mercury.
  3. Take B vitamins. A Columbia University study showed that supplementing with Vitamins B6, B12 and folic acid dramatically reduced the negative impact of air pollution on DNA.
  4. Supplement alpha-lipoic acid. A powerful antioxidant, this naturally occurring compound possesses metal-chelating activity. Both fat- and water-soluble, it is readily absorbed from the gut and crosses cellular and blood-brain membrane barriers.
  5. Consider phosphatidylserine — one of the most tested nutrients for brain health and memory. This nutrient is a key building block for brain cells.
  6. Eat plenty of antioxidant-rich foods like blueberries, dark chocolate, kidney beans and cherries to combat the oxidative stress behind cognitive decline.
  7. Boost your master antioxidant. As you age, your body produces less glutathione, which you need to protect you from the oxidative stress brought on by air pollution. Cruciferous vegetables and other foods can boost your glutathione levels.
  8. Supplement with CoQ10 and PQQ. Together, these two enzymes help protect the brain’s neuron cells (the cells that pollution particles hitch a ride on to get directly to your cerebellum) by boosting mitochondria and reducing oxidative stress.
  9. Consider EDTA chelation. Chelation uses a binding agent to “grab on” to harmful contaminants and eliminate them.
