Proteins
A hen's egg lists about 1 g of carbohydrate per 100 g in this library, so eggs barely register for blood sugar. The question in pregnancy is salmonella, and how well the egg is cooked. 9 of the 10 foods here carry that caution; only the egg-white wraps, which are already cooked, don't. The answer depends on where your eggs come from more than for almost any other food. The NHS's advice, which this library's badges follow, rests on two British schemes, British Lion and Laid in Britain, and doesn't carry over to eggs from elsewhere. US, Spanish and French advice is stricter; Danish advice is milder. This guide says which rule applies where. The Proteins guide has the short version.

Here for the stamp rule: runny only if British Lion or Laid in Britain; otherwise cooked firm.
The same stamp rule as any hen egg; the enrichment changes the fat, not the cooking rule.
Here for the carton rule: cook them firm, or use a carton labelled pasteurised.
Already cooked: about 18 g of protein and no carbohydrate per 100 g.
Here for the other-birds rule: cooked until the white and the yolk are solid.
Here for the same rule: cooked until solid, never soft-boiled, by the NHS's advice.
Every food here but one carries the egg rule, so the six featured are chosen to show how it applies: hen eggs with and without enrichment, whites, a cooked egg-white product, and two eggs from other birds.
The NHS says hen eggs with the red British Lion stamp, or produced under the Laid in Britain scheme, can be eaten raw, partially cooked with a runny yolk, or well cooked, because they are less likely to contain salmonella. Hen eggs from neither scheme should only be eaten well cooked. It adds that salmonella is unlikely to harm the baby, but food poisoning can make you seriously unwell.[1]
The British schemes don't apply to eggs from elsewhere. The US FDA, which lists pregnant women among the people at greater risk of severe salmonella illness, advises cooking eggs until both the yolk and the white are firm, and scrambled eggs until they are no longer runny. Where there's no British Lion or Laid in Britain mark, that is the rule to use.[1] [2]
The NHS says duck, goose and quail eggs can be eaten in pregnancy if they are well cooked, and lists raw or undercooked ones among the foods to avoid. The British schemes cover hen eggs only. This library marks duck, goose, quail, turkey and ostrich eggs the same way: cooked until both the white and the yolk are solid, so no soft-boiled quail eggs as a garnish.[1]
The NHS says mayonnaise and mousse made with raw eggs are fine if the eggs are British Lion or Laid in Britain. For dishes served with raw or undercooked egg, the FDA advises pasteurised shell eggs or pasteurised egg products, and cooking egg dishes such as casseroles to 160°F (71°C). Cartons of pasteurised egg white are the simple route for shakes and icing. The NHS also lists pre-packaged sandwiches and salads containing egg among the foods to be careful with.[1] [2]

Made with British Lion or Laid in Britain eggs, yes, according to the NHS. Made with other raw eggs, no; the FDA advises pasteurised eggs for anything served with raw egg.[1] [2]
Yes, well cooked. The NHS says duck, goose and quail eggs are fine in pregnancy if they're well cooked, and lists raw or undercooked ones among the foods to avoid.[1]
Every pregnancy is different, and gestational diabetes is managed differently depending on your readings, your medication and how far along you are. The ratings and portions on this page are general information — not a diagnosis, a treatment plan or a medical device — and they cannot see your results.
Contact your care team the same day if: your readings stay above target for several days; you have a reading below 54 mg/dL (3.0 mmol/L) or needed someone else's help to treat a low; you test positive for ketones; or your baby is moving less than usual. Seek emergency care for confusion, fainting, repeated vomiting, or a low you cannot bring back up.
