Dr. Joseph Mercola - Take Control of Your Health Microplastics Could Be Weakening Your Bones, New Study Finds
Dec 24, 2025
A recent study reveals microplastics are infiltrating human bones, disrupting bone health and increasing fragility. These pollutants not only affect bone structure but have also been found in vital organs like the brain and heart. With ultrafine combustion particles posing an even greater risk, experts suggest practical tips to reduce exposure. Recommendations include switching to natural materials, filtering air and water, and ditching plastic kitchen items for safer alternatives.

Butyrate Drives Broad Metabolic Benefits
- Butyrate links to improved weight, lipids, insulin sensitivity, and steadier blood sugar.
- It acts via gene pathways and receptors across intestine, fat, muscle, liver, pancreas, and vessels.
Colon Cells Prefer Butyrate Over Glucose
- Colonocytes prefer butyrate and use it for roughly 70–80% of their energy via beta-oxidation to acetyl-CoA.
- Efficient butyrate oxidation lowers colonic oxygen, favoring beneficial anaerobes and microbiome balance.
Butyrate Strengthens The Gut Barrier
- Butyrate strengthens gut barrier by upregulating tight-junction proteins and activating AMPK.
- It reduces permeability and gut-driven inflammation tied to metabolic disease.
