Microplastics and your health: what the evidence shows, graded
Plastic is in us. Whether it's hurting us is a separate question. We grade every major claim, from blood to brains to heart attacks, by how good the evidence actually is.

Thousands of fluorinated chemicals, some of them plastics, most barely breaking down. What the evidence says about harm, where the rules stand in late 2026, and what lowers your exposure.
Phthalates explained: what they are, what the evidence says and how to eat fewer of them
The softeners in vinyl and the fixatives in fragrance end up in almost everyone. What the science shows about harm, how the US and EU regulate them, and which fixes actually work.
Plastic types #1 to #7: what each resin code means for your health and the bin
PET, HDPE, PVC, LDPE, PP, PS and the #7 grab bag: where each turns up, what leaches or sheds from it, how much actually gets recycled, and which to avoid.
