There are very few foods that pregnant women need to avoid and many healthy foods that they should continue to eat throughout pregnancy. It is important to emphasise with pregnant women that eating fresh, healthy food and avoiding certain raw and undercooked food is what is important.
The Food Standards Agency’s Eatwell website contains detailed information on what women should avoid during pregnancy.
Although there is no conclusive evidence on the effect of low levels of alcohol on the foetus, current advice for women who are pregnant or trying to conceive is for them to avoid alcohol entirely, as this is the only level of consumption during pregnancy which ensures no damage to the foetus or mother.
If a woman chooses to drink, she should be informed that drinking no more than one or two units of alcohol once or twice per week, and avoiding episodes of intoxication, reduces the risk of harming a developing foetus. This website contains useful information.
