The advice to expectant mums used to be that they should avoid eating peanuts or other allergenic foods before or during pregnancy. However a new study published by Boston Children’s Hospital finds that the opposite may be true.

They studied over 10,000 women and their children and discovered that among mothers without peanut allergy, higher consumption of peanut was associated with lower risk of allergy in their offspring.

They conclude that early allergen exposure increases tolerance and lowers risk of childhood food allergy.

Peanuts are not technically a nut – they are a legume and rich in heart-friendly mono-unsaturated fats. They are also a good source of the mineral manganese, the vitamin B3 and protein.  Peanut butter on wholemeal or rye toast makes a healthy low-GL breakfast, and adding a scoop of peanut butter to smoothies adds nutritional value and extra protein.

Peanuts can be susceptible to moulds and fungus, so make sure yours are fresh.
