Mindsip insights from this episode:
Address iron overload as a potential symptom of C15 deficiency
Dysmetabolic iron overload syndrome in humans may be a symptom of C15 deficiency, as the lack of C15 makes red blood cells fragile and leads to iron accumulation in the liver.
Address C15 deficiency to slow aging process
A deficiency in the essential fatty acid C15 can lead to a form of cell death called ferroptosis, which accelerates the aging process.
Choose grass-fed dairy for higher C15 content
Dairy from grass-fed cows contains twice as much of the beneficial fat C15 as dairy from corn-fed cows.
Choose fermented butter for enhanced nutrient absorption
The fermentation process in cultured butter cleaves fatty acids into their free, more bioavailable form, increasing their absorption.
C15 surpasses leading longevity drugs in cellular studies
In head-to-head studies on cellular models, C15 has been shown to outperform leading longevity drugs like rapamycin, metformin, and acarbose.
Differentiate between beneficial odd-chain and harmful even-chain saturated fats
Odd-chain saturated fats like C15 are beneficial, while common even-chain saturated fats like C16 and C18 can be pro-inflammatory.
Ensure adequate C15 for newborn health and allergy prevention
A mother's C15 deficiency is passed to her baby through breast milk and is linked to a higher risk of allergies and type 1 diabetes in the child.
Leverage C15 to enhance sleep, mood, and pain relief
Your body converts C15 into a molecule called PDC, which is a full-acting endocannabinoid that may improve sleep, mood, and pain.
