I underwent The Royal Prince Alfred Hospital (RPAH) exclusion diet protocol in 1985 (1) which involved a few-foods diet until symptoms settled, followed by food challenges, then a modified diet excluding only problem foods. Lastly, there was moderation of the diet up to my level of food tolerance.
Some of the food challenges raised my blood pressure.
High blood pressure (hypertension) is a medical condition in which blood pressure pumping through the arteries is elevated compared to what is considered normal. It is a major risk for coronary heart disease and can lead to long-term complications such as vision problems, or kidney disease. My own father had uncontrollable high blood pressure and died of stroke in 1974 age 49 years. His mother and aunt also had strokes.
After my father had a heart attack, our family diet changed to avoidance of fatty red meat, full-fat milk and butter to one including more fish, chicken and vegetable oils. Those messages and promotion of fibre and fruit, and less refined cereals and sugar stuck with me. Thus, when I started out on motherhood I had high ideals of a healthy diet being wholegrain cereals, vegetables, fruit; and avoidance of excess fat, salt, sugar and refined cereals.
My ideals came crashing down when my second son was a failure to thrive, suffering chronic ill-health from the introduction of solid food. After a three year battle, I sought advice from a specialist at the Royal Prince Alfred Hospital (RPAH) in Sydney. An exclusion diet and series of food challenges (1), proved he was sensitive to salicylates, amines and some food additives (colours, preservatives and MSG). Salicylates are flavour components of many fruits, juices and vegetables. Amines occur in cheese, chocolate, bananas and yeast extracts. On a diet removing those foods he became well and gained weight.
