Effect of organic food on children's health
Within the Koala research project (2008-2012), the Louis Bolk Institute investigated whether organic food has a positive effect on health. The study focused on children aged 7-8 and the development of obesity and allergies in this age group. Results were compared to data collected during an earlier phase of the project (2000-2007). We conducted this study in collaboration with Maastricht University. The project was funded by the Ministry of Economic Affairs within the framework of the Organic Agriculture policy programme.
Why would organic food be more healthy?
In the first Koala study, comprehensive data were collected on the life style and diet of more than 2800 pregnant women. The children born from these mothers have participated in annual health screenings from their birth. This is the only study in the world that investigates the effect of organic diet and other specific life styles on the health of growing children. Two-year old children consuming chiefly organic -rather than conventional- dairy products were shown to have a 30% lower chance of eczema. In this second study, these effects were not signicant anymore. However, children consuming organic dairy products had a lower incidence of astma. Furthermore, the content of the rumenic acid and Trans-vaccenic acid (which are positive fatty acids) in breast milk was higher in women consuming biodynamic products than in the women with a conventional diet. This and various other conclusions have been published in scientific journals such as the British Journal of Nutrition, Organic Agriculture and Allergy.
