Generality
On the basis of the first law in force (n ° 327 of 29 March 1951), they could be defined diet foods:
"products to which, either by manufacturing process or by addition of particular substances, particular and / or definitive dietary properties have been conferred".
Subsequently, the Legislative Decree (DL) n ° 111 of 27 January 1992, in compliance with the EEC directive 89/398, modified the wording defining more precisely that:
"dietetic foods mean all those products to which dietary properties are conferred and intended for a" specific diet for people who are in particular physiological or pathological conditions ".
Ultimately, the ULTIMA legislation specifies that the product must be SPECIFIC for the PARTICULAR nutritional needs:
- of people with DIFFICULTY "in" absorption or with PERTURBATED METABOLISM
- of people in SPECIAL PHYSIOLOGICAL CONDITIONS
- of INFANTS or CHILDREN in EARLY infancy.
Synonyms for diet foods
Diet foods are also referred to as:
- Foods for a particular nutrition - DL 111/92

NB. The 1992 legislation EXCLUDES from dietetic products ALL those foods ONLY ADDED or REINTEGRATED in vitamins, minerals, fibers ... except for those that SHOW to be useful for achieving a specific DIETARY goal.
