Huberman: How Microplastics Impact Health & Solutions
The Hidden Danger in Your Water
Recent studies have revealed a shocking truth about bottled water: it contains far more microplastics than previously thought. While earlier estimates suggested around 30,000 particles per liter, new research shows levels reaching 400,000 particles per liter, with an average of 240,000 particles.
The solution? Avoid plastic water bottles, especially those that may have been exposed to heat during transportation. Instead, opt for stainless steel or glass containers. For home filtration, consider investing in a reverse osmosis system. While the initial cost might seem high ($300-600), it often proves more economical than continually purchasing bottled water.
Unexpected Sources
Sea salt, a seemingly natural product, is surprisingly contaminated with microplastics due to ocean pollution. The simple solution? Switch to pink Himalayan salt or other non-marine sources.
Even more alarming is the case of canned soup. Studies show that consuming just one serving of canned soup daily for five days led to a staggering 1000% increase in urinary BPA levels. While some companies now offer "BPA-free" options, these may contain other concerning compounds like BPS.
Daily Habits to Change
Paper cups, despite their innocent appearance, can be significant sources of microplastics and endocrine disruptors. When hot liquids reach 100 degrees Fahrenheit, they begin leaching these compounds from the cup's lining. Microplastics have been found throughout our bodies, making it crucial to use ceramic or stainless steel mugs whenever possible.
Carbonated water enthusiasts should take note: some brands contain significantly higher levels of forever chemicals than others. A 2020 Consumer Reports analysis found Topo Chico contained 9.76 particles per trillion of PFAS, compared to Perrier's 1.1 and San Pellegrino's 0.31.
Taking Action
While it's impossible to completely avoid microplastics in today's world, we can take steps to reduce our exposure:
Use glass or stainless steel containers
Install a reverse osmosis water filter
Choose Himalayan salt over sea salt
Avoid microwaving plastic containers
Opt for cast iron or ceramic cookware
Keep clothing longer to reduce microfiber shedding
