Are Microplastics Hormone Disruptors? The Two Different Questions Hiding Inside That One

The particle and the chemicals it carries aren't the same threat. Here's how scientists actually tell them apart.

IBS, insulin resistance, and the microbial molecule they have in common

A 2026 Cell Host & Microbe paper found that people with IBS-D and people with insulin resistance are missing the same gut-derived molecule. The mechanism runs through peripheral serotonin.

Immune system effects

What microplastics are doing to inflammation, cytokines, and the immune balance

Constipation and the gut: what the research actually says

A closer look at the biology of gut motility, the interventions with the strongest evidence, and where the "just eat more fiber" advice both helps and misleads.

The gut, creatine, and brain energy: what a 2026 depression trial actually showed

From microbe to capsule

A plain-language walkthrough of how a probiotic actually gets made, from strain library to the bottle on your counter.

Microplastics and inflammation: what you can actually do this week

A short, calm read on which everyday choices the science genuinely supports — and which ones are not worth the anxiety.

Microplastics and cognitive health

What the science suggests about tiny plastic particles, brain fog, memory, and cognitive decline

The gut, the vagus, and age-associated memory: what a 2026 Nature paper actually shows

Fertility and plastic additives

The chemicals that ride along with plastic — and why fertility clinics keep coming back to them

Sugar, the microbiome, and the liver: what the newest research actually shows

A 2026 Cell Metabolism paper found that dietary fructose is converted by gut bacteria into an alcohol-like toxin that damages the liver — and that a specific fiber strategy shuts the pathway down.

Resistant starch, the microbiome, and visceral fat: what the current RCT literature actually shows

A closer look at Type 2 resistant starch — a fiber your gut microbes ferment differently from any other — and why some people respond dramatically while others barely respond at all.
