see also Uribarri et al., 2007), including wound healing retardation (Peppa et al., 2003) in<br />
diabetics, and neurodegenerative diseases such as Alzheimer’s (Elliott, 2006). Lysinederived<br />
AGEs have been linked to cancer (Heijst et al., 2005). Higher levels of AGEs<br />
have also been detected in Creutzfeldt-Jakob Disease (CJD) patients, but the cause and<br />
consequences are unknown (Freixes et al., 2006). Glycation can increase the longevity of<br />
peptides in the intestine, possibly contributing to glycoxidation-implicated diabetes-related<br />
autoimmunity (Elliott, 2006).<br />
LY038 and its derivatives have the potential to boost AGE exposure from all foods<br />
that have a corn component, including many processed foods which are heated to high<br />
temperatures.<br />
Processing of some ready-to-eat cereals, which includes heating at temperatures over 230°C,<br />
may explain the high AGE content of these products. Also, many cereals and snack-type<br />
foods undergo an extrusion process under high pressure to produce pellets of various shapes<br />
and densities. This treatment causes major chemical changes, thermal degradation,<br />
dehydration, depolarization, and recombination of fragments all of which can promote<br />
glycoxidation (Goldberg et al., 2004, pp. 1288-1289).<br />
People in different countries are also exposed to different risks because of their<br />
culture or circumstances (also see Appendix Three for a related discussion). For example,<br />
Mexicans and Africans eat significantly more corn per capita than do New Zealanders<br />
(Table 4.5). The proportion of daily protein from corn for an African is 40 times that for<br />
New Zealanders (Table 4.5). A protein- or amino-based food hazard is therefore a<br />
quantitatively different risk for Mexicans and Africans than it is for Americans and New<br />
Zealanders. That is why international food safety guidelines (such as those developed<br />
under the Codex Alimentarius Commission) allow consumption patterns to be taken into<br />
account.<br />
Information about the known patterns of use and consumption of a food, and its derivatives<br />
should be used to estimate the likely intake of the food derived from the recombinant-DNA<br />
plant. The expected intake of the food should be used to assess the nutritional implications<br />
of the altered nutrient profile both at customary and maximal levels of consumption. Basing<br />
the estimate on the highest likely consumption provides assurance that the potential for any<br />
undesirable nutritional effects will be detected. Attention should be paid to the particular<br />
physiological characteristics and metabolic requirements of specific population groups such<br />
as infants, children, pregnant and lactating women, the elderly and those with chronic diseases<br />
or compromised immune systems (Codex, 2003, p. 19).<br />
Mexicans who live in New Zealand but retain their cultural consumption patterns<br />
may be overlooked if a regulator only bases food hazard on per capita (customary)<br />
consumption. For example, Food Standards Australia New Zealand (FSANZ) discounted<br />
food hazards from LY038 based in part on average consumption data:
