Experts estimate that 1 in 10 Americans have diets that are overtly deficient in zinc, although many more are believed to struggle with insufficiencies. Zinc is actually present in a wide variety of protein containing foods from animal products- such as red meat, egg yolk, organ meats, and seafood- to certain nuts, seeds, beans and cereal grains. The recommended daily allowance for zinc is currently set at 8-11 mg, which is certainly achievable from food sources.
Under the Transportation Security Administration (TSA) Secure Flight program, Air New Zealand is required to collect Secure Flight Passenger Data which includes a passenger's full name (as it appears on government-issued identification), date of birth, gender, and TSA issued Redress Number (if available).
The TSA's ID requirement for entering the secure part of the airport terminal is the same for domestic or international passengers. Airlines require that you show a passport, visa, or some other kind of document to confirm that you are allowed to fly to your destination. Check with your airline to be sure.
