does anyone know????????

Question

Does anyone know how much Vitamin C an Orange has and what type/kinds of food has the highest level of ZINC?

Answer 1

Yes, the USDA knows! And they have established an online database that tracks this sort of thing. You will find it here:
http://www.nal.usda.gov/fnic/foodcomp/search/

This interface allows simple searches. Enter up to 5 keywords which best describe your food item. Select a Food Group. Then click on the Submit button. If you don't get a match, check your spelling or try a related keyword. If you get too many food items, try a more specific keyword. If you enter two or more keywords, the program will search for food items which contain all of the keywords. Keywords do not have to be adjacent or in the same order as they appear in the food item. You can exclude food items by placing the word "not" in front of a keyword.

For Example: Entering "apples not canned" will produce a list of food items containing the keyword "apples" but not the keyword "canned".

Their nutritional database at:
http://www.ars.usda.gov/Services/docs.htm?docid=9673
will give you the answer on Zinc as well.
