When I grew up and started my own family, I worked hard to cook healthy, delicious meals – although I didn't quite understand at first that healthy eating is more than just 'homemade'. I ground my own grains, baked my own breads, cakes and biscuits, cooked with fresh veggies, and tried to avoid junk food – but my cooking still included plenty of sugar and refined oils and flours, and I didn't realise this was damaging our health.

Despite my best efforts at healthy eating, I always seemed to be fighting exhaustion, headaches, food reactions, recurring colds, tummy upsets, skin issues and low weight problems. My kids had similar health issues, and my last two babies struggled with breastfeeding and cried constantly. I eventually decided it was food intolerances that were the problem.
