Recommended daily intake of nutrients/energy and food/drug interactions

    Can anyone point me to a public domain database giving
    information either on recomended daily intake of nutrients
    (of particular interest would be data on how such intake
    varies with age, gender and weight, if at all) or on food
    drug interactions?

    I ask becuse I have finished a consumer software product
    that allows the user to enter, and store in a database, any
    recipe, and, using data the user has entered regarding food
    allergies and limits on intake, prepare a meal plan (and
    asociated shopping list) that meets the nutritional
    requirements of each member of the family, both by managing
    recipe ingredients and by managing serving size.

    I would like to make it more useful still by supporting the
    entry of age, gender and weight of family members, and
    using that to compute both minimum and maximum intake of
    the different nutrients, as well as entry of medications
    taken by family members (both prescription and over the
    counter, and possibly herbal concoctions), so that the user
    can ensure that each member of the family is getting enough
    of each nutrient and not too much (possibly identify
    situations where supplements might be warranted), as well
    as receive warnings should they select a food item that
    contains an ingredient that will interact badly with the
    medication(s) in use.

    Of course, my program already supports manual entry of
    minimum and maximum nutrient intake limits (so anyone who
    does have this data can enter it), but I suspect that most
    people, and possibly even many primary health care
    providers, won't have enough information on hand to enter
    that data for all, or even most, nutrients. I think it is
    preferable to provide default values computed on the basis
    of age, gender (if there are significant differences
    correlated with gender - not being a specialist in
    nutrition, I don't know) and weight, which the user can
    subsequently change, than to not have any at all.

    However, data quality is critical to me, for obvious
    reasons, so I'd prefer data coming from appropriate,
    recognized health care organizations (such as the AMA or
    like public health authorities in the US, EU or Canada), or
    at least data that has been previously published and
    critiqued in the peer-reviewed scientific literature.
