how pregnancy advice
differs around the world.

By Elara Editorial · Last reviewed: 5 July 2026 · Reviewed against WHO, NHS and ACOG guidance

A pregnant woman in London is told a soft-boiled egg is fine. Her sister in Boston is told the opposite. Neither health system is being careless — official pregnancy advice genuinely differs between countries, usually because the underlying risks do. Here is where the guidance diverges, where it agrees, and why.

runny eggs: a tale of two food supplies

This is the cleanest example of advice tracking local reality rather than universal biology. In the UK, the NHS says eggs stamped with the British Lion mark are safe to eat runny — or even raw, in mousses and mayonnaise — during pregnancy. The Lion scheme vaccinates laying hens against salmonella, and the Food Standards Agency concluded in 2017 that the risk from those eggs was low enough to lift the old restriction.

In the United States there is no equivalent national vaccination programme, so the FDA still advises pregnant women to eat eggs only when both yolk and white are cooked firm. Same egg, different food chain, different rule. If you move between the two countries mid-pregnancy, the sensible thing is to follow the rule of the country whose eggs you are eating.

alcohol: the one true universal

If food advice is a patchwork, alcohol is the exception. The WHO, the NHS, ACOG and essentially every national body now agree: there is no known safe amount of alcohol in pregnancy, and the safest approach is none at all. It was not always so uniform — UK guidance permitted “one to two units, once or twice a week” as recently as 2016, and French wine culture long treated an occasional glass as unremarkable — but the guidance has converged completely. Where countries still differ is tone, not substance: some lead with warning labels, others with quiet counselling.

caffeine: quietly aligned at 200 mg

Caffeine looks like it ought to vary, and mostly does not. The NHS and the European Food Safety Authority set the ceiling at 200 mg a day; ACOG in the US lands on “less than 200 mg” too. That is roughly two mugs of instant coffee or one strong flat white. The differences are in the footnotes — how each body counts tea, cola and chocolate — but the headline number is one of the rare places the world agrees.

raw fish: Japan and the sushi question

Western guidance treats raw fish warily: the NHS allows sushi only if the fish has been frozen first (which kills parasites), and the FDA advises avoiding raw fish in pregnancy altogether. In Japan, raw fish is a routine part of the pregnancy diet. Japanese maternal guidance focuses instead on mercury — limiting large predatory fish like tuna and swordfish — while trusting a supply chain built around very fresh, carefully handled fish, where much of the market-bound catch is frozen in transit anyway. The lesson is not that one country is reckless; it is that “raw fish” means a different product, handled a different way, in each place.

soft cheese: France’s complicated romance

The NHS avoid-list is blunt: no mould-ripened soft cheeses like brie or camembert, and no soft blue cheeses, unless cooked until steaming — the concern is listeria, which is rare but serious in pregnancy. France, home of raw-milk cheese, gives substantively the same advice — Santé publique France tells pregnant women to avoid raw-milk cheeses and to cut the rind off hard ones — but the cultural negotiation is harder, and adherence famously imperfect, in a country where an unpasteurised camembert is a birthright. Hard cheeses, and soft ones made from pasteurised milk like mozzarella and halloumi, stay on the menu everywhere.

scans and check-ups: two, three, or nearly weekly

Here the differences are structural rather than dietary. The UK’s NICE pathway offers two routine ultrasounds — a dating scan around 12 weeks and an anomaly scan around 20 — with more only if clinically indicated. Germany’s Mutterschafts-Richtlinien schedule three as standard, one per trimester. Japan sits at the far end: around fourteen antenatal visits are typical, and because most clinics have ultrasound machines in the consulting room, many women are scanned at almost every visit. Outcomes across these systems are all excellent, which is its own quiet finding: above a solid baseline, more scanning is reassurance and record-keeping more than it is added safety.

weight gain: counted in America, watched elsewhere

US antenatal care leans on the Institute of Medicine ranges — for example, 11.5–16 kg (25–35 lb) of total gain for a woman starting at a normal BMI — and weight is tracked against them at visits. The UK takes a pointedly different line: NICE recommends against routine repeated weighing in pregnancy at all, beyond the booking appointment, on the grounds that it causes anxiety without improving outcomes. Japan historically issued stricter (lower) gain targets, which were relaxed in 2021 after concern about low birth weights. Same biology, three philosophies of measurement.

supplements: the same molecule, different defaults

Folic acid is universal in principle — 400 micrograms daily before conception and through the first twelve weeks, per the NHS, ACOG and WHO alike — but delivery differs. The US, Canada and some eighty other countries fortify flour with folic acid by law, so American diets carry a baseline dose; the UK only confirmed mandatory fortification of non-wholemeal wheat flour in 2021, with rollout still working through the supply chain. Vitamin D shows the opposite pattern: the NHS specifically advises a daily 10-microgram supplement, a recommendation shaped by British latitude and British weather, while sunnier countries barely mention it. And iron is routinely supplemented in many lower-income settings under WHO guidance, but prescribed only on blood-test evidence in the UK. What is in the bottle is universal chemistry; what goes on the prescription pad is local epidemiology.

the world after the birth

Briefly, because it frames everything above: maternity leave ranges from no federal paid entitlement in the US, to 52 weeks of leave (39 paid at least partially) in the UK, to more than a year of well-paid, shareable leave in Sweden and Estonia. The country you are pregnant in shapes not just what you eat, but how long you will hold the baby before returning to work — and that context quietly colours every piece of advice a system gives.

why elara adapts to where you live

All of this is why we built Elara to localize rather than translate. The app is available in 16 languages, and its content is framed to the guidance and norms of your region — units in the measurements you actually use, food advice that matches your food supply, and appointment expectations that match your health system rather than someone else’s. A week-by-week guide written only for one country’s rules is subtly wrong for everyone else; we would rather be quietly right where you are.

If you are early in that journey, our week-by-week guide and food-safety library are a good place to start.
