enriched foods and fortified foods - ANS-foods that have had nutrients added to them
(ex. White bread)
functional foods - ANS-appear similar to conventional foods, consumes as part of the
usual diet, with demonstrated physiological benefits or with the ability to reduce chronic
disease risks beyond basic nutrient functions (ex. Oatmeal)

maintain health
, balance - ANS-providing foods of a number of different types in proportion to each other
(ex. Milks and alternatives)
calorie control - ANS-energy with food coming in should balance with the body's energy
requirements
moderation - ANS-nothing in excess, providing dietary restrictions while enjoying some
