  • Written informed consent has been obtained

    • The principal investigator, who is blinded to study treatment, will perform a case-by-case medical evaluation of children with any signs of being unhealthy or having any illness or taking medication at the time of admission. If the conditions are considered to potentially affect protein metabolism or growth, the children will not be included.

  • Concomitant participation in other studies involving dietary supplements or blood sampling
  • Living in a household with another participating child

    • The principal investigator, who is blinded to study treatment, will perform a case-by-case medical evaluation of children with any signs of being unhealthy or having any illness or taking medication at the time of admission.

5. Study Description

Brief Summary
The purpose of PROGRO is to determine which combinations of milk and plant proteins are optimal to promote growth factors in children
Detailed Description
The main objective is to assess how different protein blends affect growth factors in children. There is evidence to support that milk protein increases growth in children in both high and low-income countries. Therefore milk protein is often used in food aid for undernourished children in low-income countries. The study investigates if plant protein can partially replace milk protein without affecting growth promotion negatively. Plant protein could potentially reduce food aid costs and at the same time be a more sustainable protein source. The PROGRO study is a 3-arm randomized, controlled trial. The effect of consuming 35 g pure milk protein/day is compared to intake of 35 g milk and rapeseed protein/day (ratio 30:70 and 54:46, respectively) in 7-8 year old healthy Danish children. The intervention period is 4 weeks and measurements and blood sampling are performed at baseline, week 1 and week 4. A 3-day weighed dietary intake is recorded before each visit. The primary outcome is Insulin-like growth factor-1 (IGF-1).
