How will Conversion to Organic Cereal Production Affect Carbon Stocks in Swedish Agricultural Soils?
Soil carbon changes were modelled over 30 years with the focus on cereal crops, since leys are often managed similarly in organic and conventional agriculture. Other crops were not considered due to difficulties in large-scale cropping of oilseed rape and potatoes organically because of pest problems. Four scenarios were used: 0%, 8% (current), 20% and 100% organic cereal production. Conversion...
BACKGROUND Results of 6-wk studies suggest that high-carbohydrate diets are deleterious for people with type 2 diabetes. OBJECTIVE Our objective was to see whether long-term replacement of dietary monounsaturated fatty acids (MUFAs) with carbohydrate from breakfast cereals with either a high or a low glycemic index (GI) affected blood glucose and lipids in subjects with type 2 diabetes. DES...
It is clear from this work that thorough controlled and supervised washing by the wet method will not remove more than 50% of the original contaminants in soiled engineers' overalls. Indeed these figures may be on the liberal side as these experiments concerned contamination by clean solid-free oils. In ordinary practice the contaminants will be more tenacious due to the presence of finely divi...
BACKGROUND Intakes of whole grains and cereal fiber have been inversely associated with the risk of chronic diseases; however, their relation with total and disease-specific mortality remain unclear. We aimed to prospectively assess the association of whole grains and cereal fiber intake with all causes and cause-specific mortality. METHODS The study included 367,442 participants from the pro...
Cereal Chern. 76(2):299-302 Reversed-phase (RP-) and size-exclusion (SE-) high-performance liquid chromatography have become important methods for rapid identification of wheat and other cereal cultivars and for revealing quality differences. Accuracy and reproducibility are essential for good results. Due to recent changes in these methods, however, such as using smaller columns, lower flow ra...
In 1996, U.S. Food and Drug Administration regulations mandated the fortification of enriched cereal-grain products with folic acid, thereby emphasizing the need for validated methods for total folates in foods, particularly cereal products. The AOAC Official Methods (944.12, 960.46) currently used for the analysis of folate in foods for compliance purposes are microbiological methods. When the...
Various cereal brans (wheat, rice, barley and oat) were investigated for proximate composition, functional characteristics and certain anti-nutritional factors to assess their potentiality as protein and fibre sources. The major findings of this study are as follows: crude protein ranged from 9.615.03%, fat 4.07-19.31%, dietary fibre 14.0-38.95%, bulk density 0.39-0.59 g/ml, water absorption 11...
BACKGROUND Deoxynivalenol (DON) is a toxic fungal metabolite that frequently contaminates cereal crops. DON is toxic to animals, but the effects on humans are poorly understood, in part because exposure estimates are of limited precision. OBJECTIVES In this study we used the U.K. adult National Diet and Nutrition Survey to compare 24-hr urinary DON excretion with cereal intake. METHODS One ...
Contaminants in organically and conventionally produced winter wheat (Triticum aestivum) in Belgium.
A database has been compiled with the levels of important contaminants (mycotoxins, heavy metals and pesticides) measured from 2002 to 2005 in winter wheat (Triticum aestivum) grown in Belgium according to the organic and conventional farming systems. Assuming no further change in contaminant levels during cereal processing and during the preparation of foodstuffs, conservative intakes are esti...
