The absorption of soluble inorganic iron added to a meal increases in parallel with the absorption of nonheme iron, but ascorbic acid has a much smaller effect on insoluble iron compounds, such as ferric oxide or ferric hydroxide, which are common food contaminants.
Best Answer: The information that Carnival gave you IS CORRECT. All cruise lines have a minimum age limit and on all others there is a requirement that at least one (1) person in each cabin be age 21 or older (for Carnival its age 25). So no you cannot try a different cruise line and book a cruise, unless you have someone age 21 or older to accompany you.
Additional Rules for Adults Over 21. Adults found to be aiding a minor in acquiring alcohol are also in violation of the terms of the Carnival ticket contract. This includes serving or providing alcohol to minors anywhere aboard the cruise ship, in addition to furnishing a minor with an ID to buy alcohol.
