"Cattle are pumped full of growth hormones!" Sounds unnatural. Except here's what they don't tell you: UK/EU: Growth hormones in cattle completely banned since 1988. US (where used): Hormone-treated beef: 3.8 ng Untreated beef: 1.9 ng For perspective: Eggs: 11 ng Birth control pill: 35,000,000 ng The difference between treated and untreated is smaller than natural variation between cuts. What actually disrupts hormones: Soy (massive phytoestrogens) Plastics (BPA, phthalates) Seed oils Sugar Birth control pills
