Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Babies will be given a selection of 4 different vegetable baby foods over a 4-week trial starting from when baby is ready to start complementary feeding. Examples of vegetables include spinach and broccoli. Mothers provide food ad libitum but on the prescribed colour rotation for 4 weeks. This rotation is green vegetables, white vegetables, purple vegetables, orange vegetables (starting again from green vegetables); they change colour per meal. Adherence to this rotation will be monitored by a weekly survey and the weighed food diary. Mothers are asked to only provide the study's intervention baby foods only alongside breast or formula milk. At 9 months of age 3 test meals will be provided (green vegetable, familiar vegetable and novel vegetable). Liking and intake will be assessed using weighed food records, validated questionnaires and a video coding tool. Follow-ups at 12, 24 and 36 months of age will assess liking of vegetables using questionnaires.
