Peanuts and Allergy
The British Dietetic Association (June 1997) says there is no need to specifically delay the introduction of peanuts in families where there is no known allergy. Obviously the peanuts have to be of a suitable texture, for example smooth peanut butter.
Peanuts are a good source of calcium and protein. However, pregnant or lactating mothers from allergic families should be advised to avoid peanuts in their own diets and the introduction of peanuts and nuts to the diet of their infants should be delayed until about the age of 3 years or at an age advised by their medical practitioner.
Whole nuts are not recommended for the under the under fives due to the risk of choking.
