The primary aim of this study was to examine the effects of 48-h food deprivation on rat skeletal muscle fiber type, according to myosin heavy-chain (MyHC) isoform composition and some metabolism-related factors in both slow-type dominant and fast-type dominant muscle tissues. Male Wistar rats (7 wk old) were treated with 48-h food deprivation or ad libitum feeding as control. After the treatme...

Fast-Food Restaurant Advertising on Television and Its Influence on Youth Body Composition We examine the effects of fast-food restaurant advertising on television on the body composition of adolescents as measured by percentage body fat (PBF) and to assess the sensitivity of these effects to using conventional measures of youth obesity based on bodymass index (BMI). We merge measures of body c...

The variation in nutrient content is important because of the effects it can have in meeting nutritional requirements. It is therefore important to analyse the composition of the genetically modified food and to establish the extent to which the product is equivalent to its non-genetically modified counterpart. Statistically significant differences in composition may warrant closer examination ...

objective: in this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) chironomid larvae were examined. methods: for this purpose, 2.5 grams of food per coconut considered in the period, with three replicates and chironomid larvae during the period of 15 days in plastic pans were kept in nut...

To protect consumers’ interests, it was necessary to develop effective methods to authenticate the species composition of various food products, including meat. The prices for high quality meat are higher, so fraud does occur. Species identification requirements are also connected with the prohibition of sale of meat from certain protected animal species. Furthermore, certain cultures have reli...

Dietary fibre is a heterogeneous group of components for which several definitions and analytical methods were developed over the past decades, causing confusion among users and producers of dietary fibre data in food composition databases. An overview is given of current definitions and analytical methods. Some of the issues related to maintaining dietary fibre values in food composition datab...

Excess energy, saturated fat, sugar and salt from processed and fast foods are a major cause of chronic disease worldwide. In 2010 The Food Monitoring Group established a global branded food composition database to track the nutritional content of foods and make comparisons between countries, food companies and over time. A protocol for the project was agreed and published in 2011 with 24 colla...

BACKGROUND AND OBJECTIVE Nutrient values are influenced by the analytical method used. Food folate measured by high performance liquid chromatography (HPLC) or by microbiological assay (MA) yield different results, with in general higher results from MA than from HPLC. This leads to the question of how to deal with different analytical methods in compiling standardised and internationally compa...
