Nutrients to watch

  • Quality protein: meat, eggs, milk, soybeans and soy products (choose according to individual tolerance)
  • Iodine: seafood is a common source; after avoidance, it can be supplemented through iodised salt, eggs and milk
  • Essential fatty acids: deep-sea fish is a common source; other oils and foods can be used as suitable alternatives
  • Calcium and vitamin D: milk, soy products and sensible sun exposure

How to put this into practice

First work out exactly what really needs to be avoided, to prevent over-restriction; plan the structure of three meals according to the child's age stage, making sure staples, protein and fruit and vegetables are all included; regularly monitor height, weight and the growth curve, and when necessary ask a doctor or nutrition professional to assess whether supplements are needed.

Eating also needs care

Eating out and eating in groups can easily make a child feel singled out. Parents can prepare alternative dishes of a similar shape, and help the child prepare a sentence to explain their situation, to reduce psychological pressure.
