Your brain's immune cells are called microglia.
Their job is to protect neurons, clear toxins, and respond to threats. When they activate, do their job, and stand down — that's the system working correctly.
But chronic exposure to inflammatory food, air pollution, and environmental stressors can keep them in a constant state of activation. Not enough to send you to the ER. Enough to slowly wear down healthy brain tissue over years.
This is one of the most consistent patterns in early Alzheimer's pathology — and one of the most overlooked in conventional medicine.
Dr. Austin Perlmutter is joining me on Thursday for Episode 61 to talk about how everyday choices shape this inflammatory environment, and what the research actually supports for long-term brain protection.
Worth a listen if brain health is on your radar.
