Related Episodes for How Dr. Rhonda Patrick Reduces Everyday Microplastic Exposure

“Air pollution leaves a biological fingerprint on our lungs, our blood vessels, and even our brains, eroding the body's defenses, triggering inflammation, weakening the blood-brain barrier, and accelerating cognitive decline.”

“Exposure to environmental toxins – in the food we eat, the water we drink, and the air we breathe – is largely unavoidable. But monitoring our exposures and implementing diet and lifestyle strategies can help mitigate the risks associated with toxic exposures. In this Aliquot, Dr. Dale Bredesen, Dr. Michael Snyder, and I discuss ways to deal with our increasingly toxic environment.”

“As the blood-brain barrier breaks down, whether as a part of aging or neurodegenerative disease, immune cells, inflammatory cytokines, toxic proteins, and red blood cells gain access to the brain from the blood and contribute to cognitive dysfunction.”

“The aggregate of these exposures is referred to as the "exposome" – the totality of non-genetic exposures that a person experiences during a lifetime – and includes nutritional, environmental, microbial, financial, and emotional factors.”

“Dr. Patrick discusses paraquat and rotenone because both can damage mitochondria and are used experimentally to model Parkinson-like neurodegeneration, but that rationale does not prove that either chemical caused disease in this population.”

“In a secondary analysis of 72 men, the combined concentration of six PFAS declined by about 8 percent within the oat beta-glucan group over four weeks, while the study did not distinguish the magnitude of change from the control group.”

“A meta-analysis of 25 prospective studies associated each additional 10 grams of daily fiber with about a 10 percent lower risk of colorectal cancer, with especially consistent findings for cereal fiber and whole grains.”

“One laboratory study found that disposable paper cups exposed to 85 to 90°C water released about 25,000 micron-sized particles into 100 milliliters within 15 minutes, along with many smaller particles. Tea bags can provide another source of exposure.”

“Randomized trials and a meta-analysis show that at least three grams of oat beta-glucan per day can lower LDL by about five to seven percent, with high-molecular-weight products producing the most consistent effects.”

“A large meta-analysis found that organic crops tended to contain higher concentrations of several phenolic compounds, lower cadmium, and fewer detectable pesticide residues, but no single nutritional pattern applies to every fruit or vegetable.”
