DIAMOND contains dietary survey data for both Australia and New Zealand; the 1995 NNS from Australia that surveyed 13,858 people aged 2 years and above, and the 1997 New Zealand NNS that surveyed 4,636 people aged 15 years and above. Both of these surveys used a 24-hour food recall methodology. A second 24-hour recall was conducted on a subset of respondents in both surveys for a non-consecutive day. It is recognised that these survey data have several limitations (see Section 6). 1.3.1
Additional dietary survey data or other relevant data
The 1995 and 1997 NNSs reported very low consumer numbers of chewing gum (<1% of the population). Information provided by the Applicant in their application indicated that approximately 55% of the population are now chewing gum consumers, with an even split between males and females. Due to the differences between the NNS data and that provided by the Applicant, FSANZ requested the Applicant to provide current consumption data for chewing gum (containing no more than 0.2% residual sugars) for various population subgroups both in Australia and New Zealand. Data sought included: (1) the prevalence of consumption (e.g. the proportion of males aged 14-18 years consuming chewing gum (0.2% residual sugars)); (2) the frequency of consumption (e.g. three times per week); and (3) the number of pieces of chewing gum (0.2% residual sugars) consumed per eating occasion. From this research, it was possible to predict the additional calcium intakes from calciumfortified chewing gum (0.2% residual sugars) for each population sub-group, were the Application to be approved. FSANZ also requested data on the proportion of the population who would be interested in purchasing chewing gum (0.2% residual sugars) that was fortified with calcium, to determine the likely uptake of the product in the market.
