Egg replacements for a balanced diet

1 egg equates to about 15% of the daily requirement for protein and so eggs are important, particularly for those following a vegetarian diet.

  • Milk, meat and fish-based proteins
  • Beans and legumes
  • Nuts and seeds

When looking to directly replace egg in cooking or baking, there are alternatives which mimic the binding or thickening properties of egg such as:

  • ‘Ogran No Egg’
  • Mashed fruits (binding)
  • Cornstarch (thickening)
  • Avocado
