Can agricultural cultivation methods influence the healthfulness of crops for foods Organic Eprints
Jensen, Maja M.; Jørgensen, Henry; Halekoh, Ulrich; Olesen, Jørgen E.; Lauridsen, Charlotte.
The aim of the current study was to investigate if there are any health effects of long-term consumption of organically grown crops using a rat model. Crops were retrieved over two years from along-term field trial at three different locations in Denmark, using three different cultivation systems(OA, organic based on livestock manure; OB, organic based on green manure; and C, conventional with mineral fertilizers and pesticides)with two field replicates. The cultivation system had an impact on the nutritional quality, affecting γ-tocopherol, some amino acids, and fatty acid composition. Additionally, the nutritional quality was affected by harvest year and location. However, harvest year and location rather than cultivation system affected the measured health...

Carbohydrate and lipid composition of vegetables, and bioavalability assessed in a rat model: Impact different cultivation systems Organic Eprints
Jørgensen, Henry; Bach Knudsen, Knud Erik; Lauridsen, Charlotte.
Environmental as well as cultivation factors may greatly influence the chemical composition of plants. The main factors affecting chemical composition of foodstuff is level and type of fertilizer (conventional and organic cultivation systems), location or soiltype and year of harvest. Organic foods are defined as products which are produced under controlled cultivation conditions characterized by the absence of synthetic fertilizers and very restricted use of pesticides. Dietary carbohydrates constitute a major fraction of most feedstuffs and can be divided according to glycosidic linkage into sugars (mono- and disaccharides), oligosaccharides, starch and non-starch polysaccharides (NSP). The bulk of disaccharides and starch will be broken down by the...

Comparison between conventional and organic agriculture in terms of nutritional quality of food - a critical review Organic Eprints
Jensen, Maja M.; Jørgensen, Henry; Lauridsen, Charlotte.
The consumption of organic foods has been increasing over the last decades and organic products are becoming more visible on the market. Consumers perceive that organic foods are of better quality, more nutritious and healthier, and these perceptions are some of the main drivers of the organic market. Scientific research on organic foodstuffs is contradictory, and knowledge regarding the effect of cultivation system on the nutritive value and the possible relationship with human health could be further explored. Although some systematic differences in the nutritional content, i.e. nitrogen, protein, vitamin C, phosphorous and phenolic compounds of plant products grown under different cultivation systems have been observed, it is a difficult task to prove...

Dependent on dietary treatments of mothers, rats showed individual preference of diets containing ingredients produced with different cultivation strategies Organic Eprints
Yong, C.; Halekoh, Ulrich; Jørgensen, Henry; Lauridsen, Charlotte.
Three diets were prepared with ingredients cultivated by each of three different farming systems, low input of fertilizer without pesticides (LIminusP), low input of fertilizer and high input of pesticides (LIplusP), and high input of fertilizer and high input of pesticides (HIplusP). A preference test was conducted to investigate whether rats could distinguish among the three iso-energetic and iso-nitrogeneous diets, and the influence of the mothers’ diet was accordingly studied with regard to the food choice of the progeny. The experimental diets contained potatoes, carrots, peas, green kales, apples, and rapeseed oil and were formulated to meet the NRC requirements for growing rats by mixing. Rats were weaned from dams, which had been fed one of the...

Effect of organic diet on biomarkers of health and well-being in rat models Organic Eprints
Lauridsen, Charlotte; Halekoh, Ulrich; Jacobsen, M.; Jørgensen, Henry.
Most studies reported in the literature on organic versus conventional production systems and health impact suffer from the fact that only one replication per food produce was used, whereby the variation due to other sources could not be estimated. The overall objective of the present studies was to study the effects of foods - based on well-defined and well-controlled food produce systems - on health and well-being after long-term consumption using the rat as a model.

Health biomarkers in a rat model after intake of organically grown carrots Organic Eprints
Jensen, Maja M.; Jørgensen, Henry; Halekoh, Ulrich; Watzl, Bernhard; Thorup-Kristensen, Kristian; Lauridsen, Charlotte.
BACKGROUND: Organic food is perceived as being of better quality and healthier than conventional foods although the scientific research on organic foodstuffs is highly contradictory. The aim of the present study was to investigate if an intake of carrots from four different cultivation systems grown in two consecutive years would influence various biomarkers of health in a rat model. All rats were fed a diet with 40% carrot content. The carrots were grown under conventional (C), “minimalistic” organic (O1), organic (O2), or “very” organic cultivation systems (O3). A control group (CO) being fed standard rat chow was included. RESULTS: The plasma α-tocopherol concentration was higher in the O2 carrot-based diet than in the C carrot based-diet in one year,...

How to understand the complexity of product quality and the challenges in differentiating between organically and conventionally grown products – exemplified by fresh and heat-processed carrots (Daucus carota L.) Organic Eprints
Seljåsen, Randi; Kristensen, Hanne Lakkenborg; Kretzschmar, Ursula; Birlouez, I; Paoletti, F; Lauridsen, Charlotte; Wyss, Gabriela S.; Busscher, Nicolaas; Mengheri, Elena; Sinesio, F.; Zanoli, Raffaele; Vairo, Daniela; Beck, Alexander; Kahl, J..
Quality traits are highly focused upon in the marketing of organic food products. There is a need to define and measure quality as consumers seem to have preconceived notions about the superior health value and taste of organic compared to non-organic products. A commonly held opinion among many consumer groups is that organic farming guarantees optimum quality, despite the fact that this remains unproven. The aim of this paper is to contribute to a better understanding of the complexity of quality traits in a plant-based food product, using carrots as an example. Selected designated quality aspects are presented to describe the complexity of quality and discuss the challenges of using these aspects in differentiating between organic and conventional...

Inoculation of weaned pigs with E. coli reduces depots of vitamin E Organic Eprints
Lauridsen, Charlotte; Vestergaard, Ellen-Margrethe; Højsgaard, Søren; Jensen, Søren K..
This study was designed to investigate the effect of vitamin E supplementation on vitamin E depots and immune responses in weaned pigs after an E. coli inoculation. The design was a 2×2 factorial with vitamin E supplementation (150 mg/kg RRR-α-tocopheryl acetate versus a control diet containing 60 mg all-rac-α-tocopheryl acetate) and E. coli 0 149 inoculation (inoculation of 1×108 CFU on day 2 and 3 after weaning versus inoculation of vehicle). The pigs were housed individually during the experiment which lasted for 10 days from weaning at 7 weeks of age. Blood was sampled on day 1 (day of weaning) and 9 of the experiment, and serum was analyzed for α-tocopherol concentration. On day 10 of the experiment, pigs were killed and samples of liver, heart,...

Nutrient composition and bioavailability of protein and energy in common fruits and vegetables prepared for human consumption Organic Eprints
Jørgensen, Henry; Lauridsen, Charlotte.
Growing rats were used as animal model to evaluate the digestibility of energy and protein digestible corrected amino acid score (PDCAAS) in some common fruits and vegetable grown during two subsequent growth seasons in different cultivation systems. The ingredients were cultivated by each of three different farming strategies: LIminusP: low input of feritlizer without pesticides, LIplusP: lowinput of fertilicer and high input of pesticides and LHplusP: high input of fertilizer and high input of pesticides. The protein quality of the dietary ingredients gave rise to the following ranking: apples, carrots, potatoes, kale and peas. The amino acid pattern in peas and potatoes complemented each other fairly well as dietary sources, while lysine turned out to...

Optimering af økologiske produkters kvalitet (Qaccp) Organic Eprints
Lauridsen, Charlotte; Kristensen, Hanne L.; Jørgensen, Henry.
Forbrugerne efterspørger i stigende grad sundere og mere sikre fødevarer af høj kvalitet, og mange forbrugere har en forventning om, at økologiske fødevarer har højere kvalitet end ikke-økologiske. Det har man hidtil ikke kunnet bevise, bl.a. pga. manglen på videnskabelige undersøgelser af økologiske produktionsmetoders indflydelse på kvalitet og sundhedseffekt. Formålet med projektet var at optimere den økologiske produktion og forarbejdning med henblik på at forbedre fødevarekvalitet og at øge sundhedsfremmende aspekter for økologiske produkter.

Organic diets and physical activity: Research experience using a rat model Organic Eprints
Jørgensen, Henry; Halekoh, Ulrich; Lauridsen, Charlotte.
Total energy expenditure or heat production is comprised of basal metabolic rate, thermic effect of food, and physical activity. Physical activity is the most variable and easily altered component of total heat production. Physical activity is influenced by a number of biological parameters i.e. diet, genetics, age, and gender. The diet components of the macro as well as micronutrients and other components (secondary metabolites) associated with a diet could contribute to the well being of the animal and cause variation in physical activity. In order to investigate physical activity as a parameter to differentiate diets based on conventional or organic grown carrots the total heat production and physical activity was measured in a rat model. The...

Organic Food and Health: A new project to study the effects of plant cultivation methods (organic and conventional) on nutritional value, health and reproduction in an animal experiment Organic Eprints
Brandt, Kirsten; Nygaard Larsen, Hanne; Andersen, Jens-Otto; Mølgaard, Jens-Peter; Lauridsen, Charlotte; Jørgensen, Henry; Gundersen, Vagn; Larsen, Erik; Badsberg, Jens Henrik; Thorup-Kristensen, Kristian.
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...

Organic food and health – status and future perspectives Organic Eprints
Lauridsen, Charlotte; Jørgensen, Henry; Halekoh, Ulrich; Christensen, Lars Porskjær.
The effect of three iso-energetic and iso-nitrogeneous diets composed of ingredients originating from three different cultivation systems (“Organic”, low input of fertilizer without pesticides; “Minimally fertilised”, low input of fertilizer and high input of pesticides, “Conventional”, high input of fertilizer and high input of pesticides) was investigated with respect to several physiological responses and biomarkers of health using a rat model. The diets were optimized according to the nutritional requirements of rats, except for a high content of fat. The diets consisted of equal proportions of potatoes, carrots, peas, green kale, apples, and rapeseed oil, which were grown according to three different cultivation systems. Even though most of the...
