Benefits and Dangers with Additives
FDA - list of food additives (over 3,000), petition process
extensive approval process
Some available in US that aren't in other countries
Many additives harmful still - e.g. sodium nitrate, olestra
Trend towards more natural ingredients is strong in U.S.
This is more expensive in a staggering economy (shorter shelf life)
Lack of standardization (mixture of active ingredients often poorly characterized, FDA budget already too low to also certify quality of organic materials)
Environmental concerns growing (additives act as contaminants not only to the human body)
Issues with testing
Additives tested in isolation--effects in combination unknown
Ethics (testing on animals)
-Availability & Urbanization
-Nutrition (Maintain and Improve)
