On the weekend a story by lawyer David Gillespie was published in several newspapers promoting his new book titled ‘Toxic Oil’. I’ve also tracked down an extract from his book on the internet. Mr Gillespie’s theme is that the consumption of vegetable oils, especially oils rich in omega 6, is killing us.There are so many errors and misleading statements in these short extracts that I can’t say I am looking forward to reading the full book. Here is a taste.
Gillespie says: … the amount of omega 6 oil we consume has exploded … our average polyunsaturated fat intake is currently … 11 per cent of our total calorie intake – more than double what it was in 1996.
This is just plain wrong. Intake of polyunsaturated fat in Australia has never been anywhere near as high as 11 percent of daily calories and rather than ‘exploding’ it has been declining for three decades.
The evidence on this issue is available to all in the two National Nutrition Surveys in 1983 and 1995, two CSIRO surveys and the 2007 Children’s Nutrition and Physical Activity Survey. The overall picture is one of a steady decline in polyunsaturated fat intake from 1983 until the present. Page 17 of the latest survey report shows children’s intake of polyunsaturated fats to be just 4 percent of total calorie intake across both genders and all age groups, about a third of that claimed by Mr Gillespie. Children’s intake of polyunsaturated fat is little different from the mean intake of men and women of 4.5 percent of daily calories observed in the last survey of adults in 1995.
Where did Mr Gillespie get his figures from?
