“De reden die consumenten opgeven om van de koop van biologische producten af te zien is de prijs. Maar liefst 68% geeft aan biologische producten te duur te vinden en daarom niet vaker dergelijke producten aan te schaffen.”

Een andere reden om bio in de schappen te laten liggen is mogelijk het onbiologische gehalte van de waar.
Fraude met biologisch eten: overtreders komen er mee weg
“Bij 68 bedrijven bestaat het vermoeden dat ze de afgelopen jaren ten onrechte producten als biologisch hebben verkocht of aangeprezen. Met de handel zouden tonnen zijn verdiend. Het gaat om witlof, koffie, vlees, chocolade en nog veel meer. Er is kritiek op de aanpak: overtreders zouden er te gemakkelijk mee weg komen.”
Daarnaast is biologisch (‘organic’) niet automatisch gezonder of per definitie planeetvriendelijker.

Organic food and impact on human health: Assessing the status quo and prospects of research
Abstract
The paper gives an overview of recent studies investigating the health value of organic foods and presents a framework for estimating the scientific impact of these studies. Furthermore, the problems connected with the different research approaches are being discussed. A number of comparative studies showed lower nitrate contents and less pesticide residues, but usually higher levels of vitamin C and phenolic compounds in organic plant products, as well as higher levels of omega-3 fatty acids and conjugated linoleic acid in milk from organically raised animals. However, the variation in outcomes of comparative studies is very high, depending on plant fertilization, ripening stage and plant age at harvest, and weather conditions. Moreover, there appeared no simple relationship between nutritional value and health effects. It is difficult therefore to draw conclusions from analytical data about the health effects of organic foods. Some in vitro studies comparing health-related properties of organic vs conventional foods showed higher antioxidative and antimutagenic activity as well as better inhibition of cancer cell proliferation of organically produced food. If ‘health effects’ are defined as effects on defined diseases in humans, evidence for such effects is presently lacking. Animal studies carried out so far have demonstrated positive effects of an organic diet on weight, growth, fertility indices and immune system. Recent human epidemiological studies associated consumption of organic foods with lower risks of allergies, whereas findings of human intervention studies were still ambiguous. The hypothesis might be that organic food increases the capacity of living organisms towards resilience. To confirm this, effect studies on specific markers for health are necessary.

Organic food worse for the climate?
Organically farmed food has a bigger climate impact than conventionally farmed food, due to the greater areas of land required. This is the finding of a new international study involving Chalmers University of Technology, Sweden, published in the journal Nature.

All the reasons why organic food doesn’t deserve such bad press
Negative headlines about organic farming’s carbon footprint are missing the bigger picture about its environmental benefits, say Christel Cederberg and Hayo van der Werf
