Growing a baby takes a lot of nutrition, and a balanced diet at the time of conceiving gives your little one the best chance of growing well.

Nutrition
Recommendations are for a balanced diet, including fruit and vegetables, wholegrain carbohydrates, adequate calcium intake, balanced protein sources every day, and iron rich foods. If you use added salt, please choose an iodised version.
There is a small amount of evidence which shows an association between high caffeine intake and miscarriage or difficulty conceiving, but it is not very strong. You could consider limiting your caffeine intake to less than 200mcg (1-2 cups of coffee) daily when you are trying to conceive.
