If a pregnant woman has not had pre-conception counselling, it is important to ensure as soon as possible in early pregnancy that she understands her nutrient requirements, and what comprises a balanced diet and healthy body composition. The advice should include weight gain goals in pregnancy, a list of unsafe foods, healthy exercise behaviours, and the effects of alcohol and drugs. Energy intake needs in early pregnancy do not increase from pre-pregnancy levels; women should focus on eating well for pregnancy, and not eating more. Specific attention should be paid to intakes of folate, vitamin A, vitamin B12, vitamin D, iron, and iodine. Glucose status should be monitored in mid-pregnancy. Energy requirements increase in mid- to late pregnancy, but attention should also be paid to the macronutrient balance. If the diet is low in oily fish as a source of polyunsaturated fatty acids, supplementation should be considered.
