In a leading peer-reviewed nutritional journal published this week, Dr Adam Drewnowski's report concludes that 53% of the variance in a food or drink product was determined by the number of calories (or energy density) alone and that the contribution of other components to the score was relatively minor.
“The NPM pretty much tells you nothing more than you can learn from the assessment of the amount of calories per 100g,” said Drewnowski, who is director of the nutritional sciences program at the School of Public Health and Community Medicine at the University of Washington in Seattle.
The report comes just hours before the FSA is set to begin its review of the controversial model, which The Grocer has been campaigning to overturn. It will be an embarrassing reminder to the FSA that despite its insistence that the methodology had been scrupulously and independently tested, a number of scientists and nutritionists around the globe are strongly opposed to the system.
