A trade association representing manufacturers of specialist dietetic foods, particularly those formulated for infants and young children. Abbreviated IDFA, it speaks for producers of infant formula, follow-on formula, weaning foods, and foods for special medical purposes. The association engages with regulators on compositional standards, labelling rules, and advertising restrictions in this tightly controlled sector, and it provides members with technical guidance on safety and compliance. Its codes of practice reflect the vulnerability of the consumers involved. Through collective representation, the association helps ensure that early-life nutrition products meet rigorous quality and safety expectations.
