Mindsip insights from this episode:

Incorporate liver as a nutrient-dense brain superfood

When compared nutrient-for-nutrient, liver is one of the most powerful brain foods, appearing far more nutrient-dense than even the best vegetables.

Get a brain cognoscopy to assess cognitive decline risk

A 'cognoscopy' is a concept for a comprehensive evaluation of biomarkers, like a colonoscopy for your brain, to determine your risk and trajectory for cognitive decline early on.

Recognize Alzheimer's as type 3 diabetes to understand brain health

Alzheimer's is now being called 'Type 3 Diabetes' because it involves insulin resistance within the brain, which is a primary driver of the disease.

Recognize amyloid plaque as a protective defense mechanism in the brain

The brain produces amyloid plaque not just as a pathology, but as an antimicrobial defense mechanism when it's under attack by microbes like viruses or bacteria.

Recognize brain microbiome's role in Alzheimer's disease

Contrary to popular belief, the brain is not sterile and has its own microbiome, with researchers finding microbes like candida and bacteria from gum disease in the brains of Alzheimer's patients.

Prioritize fasting insulin test over blood sugar for metabolic health

A fasting insulin test is a much better early indicator of metabolic dysfunction and dementia risk than a standard blood sugar test, yet most doctors don't check it.

Reduce belly fat to protect brain health

There is a direct relationship between the size of your belly and the size of your brain, as the visceral fat that causes a bigger belly also drives inflammation that shrinks the brain.

Reverse biological age with a specific diet in eight weeks

A recent study showed it's possible to reverse biological age by over three years in just eight weeks using a prescribed diet of specific foods that regulate aging, without any supplements.
