About & sources

PregFacts started with liquorice. Learning — almost by accident — that eating a lot of it in pregnancy has been linked to effects on a child’s development raised an uncomfortable question: what else don’t we know?

It turns out there’s a lot. Much of it is in official guidance, but spread across dozens of pages that few people have time to read. PregFacts collects the surprising, useful parts in one calm place — 42 tips so far — and explains each one in about two minutes.

How we write every tip

• The answer comes first. Each page opens with a short, direct answer, then explains why it matters and what to do.
• Official sources only. We base tips on guidance from national health bodies and professional organisations — such as the NHS, CDC, FDA, ACOG, RCOG and UKHSA — and on peer-reviewed research. Every tip links to its sources.
• Country differences are flagged. Advice sometimes differs between the UK, US and other countries. Where it does, we say so.
• No fear-mongering. Where the risk is small, we say that too. The aim is to inform, not to frighten.
• Medically reviewed. Every tip is checked for medical accuracy by Dr. Christopher Sterling, an obstetrician with 24 years of experience — see below.
• Regularly reviewed. Guidance changes — for example, the NHS recently updated its advice on sushi and pâté, and we updated our tips. All content was last reviewed on 29 September 2026.
