| In addition to improved yields, the use of organic methods can benefit the nutritional value of foods in several ways, compared with subsistence agriculture, and in some respects also when compared with the use of high-input conventional farming methods. The recycling of organic matter retards depletion of the soil and ensures that increases in yield are not offset by mineral deficiencies caused by unbalanced plant nutrition. City populations can use organic products to minimize their intake of pesticide residues and nitrate. Improved nutritional status of crops under low-input conditions can increase the contents of protein and vitamin A, but can also increase the contents of some anti-nutrients. Improved availability of firewood through agroforestry... |

| In 2000-2001 a review was produced on the topic "Organic food and human health", (http://www.agrsci.dk/foejo/DK/sider/pub/fojorap.html ). The review evaluated a large number of studies comparing the constituents of organic and conventional foods, as well as feeding studies comparing reproduction and health of animals fed with organic or conventional feed. Additionally studies on the connection between consumer values and food production systems were reviewed. The results showed that organic plant foods consistently contain more vitamin C, natural pesticides and higher dry weight percentage, less b-carotene, pesticide residues and protein, but the protein has a higher percentage of essential amino acids than in conventional plants. Organic animal... |

| The possible differences between organic and conventional plant products are examined from the view of possible effects on human health. It is concluded that nutritionally important differences relating to contents of minerals, vitamins, protein and carbohydrates are not likely, primarily since neither of these are deficient in typical first world diets, nor are present levels of pesticide residues in conventional products cause for concern. However, there is reason to believe that contents of many defence related secondary metabolites in the diet are lower than optimal for human health, even for those where too high levels are known to be harmful. High biological activity resulting in adverse effects on growth of animals and children may be directly... |

| The overall objective is to determine, if conventional and organic food products show differences in effects on animal physiology, of a type and magnitude, that indicates that such products will affect humans differently. The agricultural treatments used are: 1: An organic cultivation treatment, with low input of nutrients through animal manure and use of catch crops, and no pesticides. 2: A conventional cultivation system, with high input of nutrients through mineral fertiliser and intensive use of pesticides. 3: A combination of 1 and 2, with low input of nutrients, primarily animal manure, and intensive use of pesticides. The treatments will be established on two sites. Wheat, potatoes and oilseed rape will be produced in Foulum, and carrots,... |

| Many consumers believe that food from plants grown under certain conditions, such as organic agriculture, will benefit health more than conventional food. This cannot be determined simply by analysing the material, since our understanding of the connections between food components and health is still to imprecise for such a purpose. Rather than waiting until basic research provides the knowledge needed for this approach, in the spring of 2001 we have initiated a project to study physiological effects of plant quality directly, in an animal experiment. The following cultivation treatments are used to grow plants that are typical ingredients for a human diet (potato, mature peas, kale, spring wheat, oilseed rape, carrots and apples): 1. A model of a... |

| The field resistance and the concentration of phenolic compounds of five black currant varieties grown under organic conditions were compared Significant differences between varieties were seen for all of seven quantified hydroxycinnamic acid derivatives The variety 'Intercontinental' clearly contained the highest level of hydroxycinnamlc acid esters and at the same time was the most resistant variety There seems to be a connection between the content of a caffeoyl-di-quinic acid ester and coumaryl-quinic acid ester and disease resistance under field conditions The effect of four different growing conditions was much less evident Analysis of the content of these phenolic acids might be a tool to help choosing the disease resistant varieties that are... |

| In the recent years there has been an increasing focus on the quality and health value of organic plant products compared with conventional products. The use of pesticides and concentrated fertilisers in conventional agriculture implies a risk of effects on plant composition, which may affect health of the consumer (Brandt & Mølgaard, 2001). To determine if organically grown plant food could provide more or less benefits to health than conventional food, a first step is to investigate the differences in the composition and relative concentration of natural compounds in the plant products. In this project apples were grown with two levels of nitrogen availability and with or without the use of pesticides. The apples were screened for changes in the... |
