| 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... |

| 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... |

| 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,... |

| Mange forbrugere anser økologiske fødevarer for at være af bedre kvalitet, sundere og mere næringsrige end fødevarer produceret ved konventionelle metoder. Men forskning på området, der kan fastslå en sådan sammenhæng, er enten ikke tilstede eller mangelfuld. Ingen forskningsresultater, der kan be- eller afkræfte forbrugernes opfattelse. |

| Four dietary factors (ad libitum versus feed restriction, control versus protein restriction at ad libitum feeding, control versus inclusion of lupine as a protein source at ad libitum feeding, and control versus extra vitamin E at ad libitum feeding) were tested in four separate experiments for the effect on diarrhoea. To introduce a diarrhoea-like condition, half of the piglets were challenged with an inoculation of an E. coli O 149 dose of 1 x 108 colony forming units on day two and three after weaning (day of weaning = day one). All piglets were susceptible since the dams were tested mono-zygotic susceptible to the attachment site of E. coli O 149 in the intestines. Each of the four experiments included 32 piglets from 4 sows. The design was 2 x 2... |

| The aim of the study was to measure protein utilization and energy value of dried apple, carrot, kale, pea, and potato prepared for human consumption and grown in 2 consecutive years with 3 different farming systems: (1) low input of fertilizer without pesticides (LIminusP), (2) low input of fertilizers and high input of pesticides (LIplusP), (3) and high input of fertilizers and high input of pesticides (HIplusP). In addition, the study goal was to verify the nutritional values, taking into consideration the physiologic state. In experiment 1, the nutritive values, including protein digestibility-corrected amino acid score, were determined in single ingredients in trials with young rats (3-4 weeks) as recommended by the Food and Agriculture Organization... |

| A preference test was conducted to investigate whether rats could distinguish among three iso-energetic and iso-nitrogeneous human diets prepared with ingredients 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 experimental diets were formulated to meet the NRC requirements for growing rats by mixing potatoes, carrots, peas, green kales, apples, and rapeseed oil. For five days, rats (N=27) had free access to each of the three diets, and consumption of each of the diets was recorded daily. Thereafter, rats were offered a standard laboratory chow until the test... |

| 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... |

| 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... |

| Food preference tests represent an approach in food quality research, taking advantage of the instinctive feeding behavior of animals by allowing them to choose between food samples. A great number of investigations using laboratory rats concerning essential and/or dangerous contents are based on this method and have shown its effectiveness. The selection of food is influenced to some degree by smell and taste, but mostly by wholesomeness and need. In the present study a preference test was used in order to test eventual selective differences among rats with regard to same composition, but cultivated in three different systems. The experimental diets were formulated to meet the NRC requirements for rats by mixing 40% of freeze dried carrots with an... |

| 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,... |

| 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... |

| 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... |
