For a program I'm writing (which is supposed to create a balanced meal), I'm using two pieces of information: USDA's dietary reference intakes and a database (also from them) of nutrients each food product contains. There is a problem, though: the nutrients listed by the DRIs don't have a 1 to 1 correspondence with the nutrients in the database. The biggest problem is fatty acids. While the DRI says you need some omega-3 and some omega-6, no saturated or trans, the DB has no entries for Omega 3 or 6, or linoleic acid, or alpha-linoleic acid. It just lists each chemical in each group separately, leaving it to me to figure out what is what. And the way the constituent chemicals are named does not make it easy for someone who doesn't know biochemistry.
I am confused regarding whether the two linoleic acids can be replaced by the other fats in their groups.
Below, I list the chemicals available in the database, ordered by the column named "SR_Order" (sort order). You may note the annoying absence of iodine and vitamin B-7 (biotin).
