In 1995 I gradually developed CFS and was invalided out of work a year later. In late 1999 I began the RPAH elimination diet. Ten days later my brain fog and fatigue were greatly diminished. Challenges confirmed intolerance to dairy and gluten – which I had eliminated years previously – and indicated intolerances to salicylates, amines and glutamates.

In the following years I had a few relapses, usually lasting for no longer than a couple of weeks. The exception was a six months relapse, which ceased five days after I decreased my intake of vegetable oil and changed from canola to sunflower. (Both oils had no additives listed on the label)

In January 2007 I was feeling quite well and had no significant CFS relapse for a couple of years. At the beginning of February my energy plummeted. I needed to spend at least twelve hours a day lying down, instead of eight hours. Physical fatigue and brain fog returned in force. Six weeks later I bounced back, and was quite well for a few weeks, then I plummeted again. These irregular fluctuations continued throughout the year, but the highs got lower and the lows got lower. I became much more sensitive to amines.

In early February 2008 I went to Woolworths for grocery shopping. I picked up a bottle of sunflower oil and glanced automatically at the contents. In a way, I was not really looking because I ‘knew’ that nobody put additives into sunflower oil in Australia. But there it was: ‘Sunflower Oil, Antioxidants E319, E320’. I squeezed my eyes tight, reopened them, and read the same thing. Then I grinned and imagined myself leaping into the air and clicking my heels. Yes!

I phoned Woolworths and was told that their sunflower oil had E319 and E320 since the beginning of 2007. But sometimes my wife bought sunflower oil from Coles. No, Coles had never put antioxidants into their sunflower oil. We take about six weeks to consume a one litre bottle of sunflower oil. I looked back in my diary and found that the length of my ups and downs were in multiples of six weeks. We swapped to Coles sunflower oil. Eighteen days later I was fully well again. – Ian, by email
