Food allergy arises from a specific immune response induced by food exposure. It is the first cause of anaphylaxis in childhood. Its prevalence increased exponentially in western countries. The proteins most frequently involved in infants are cow's milk and hen's egg; and in adults, seafood. Peanuts have the same frequency in both groups. The clinical manifestations and methodology of study are directly related to the pathophysiology of the disease. Clinical history, skin prick test, patch test, and food oral challenge are essential to arrive at a correct diagnosis, that will avoid unnecessary exclusions or exposures that carry life risk...

Discrimination of biodiesel feedstock present in diesel-biodiesel blend is challenging due to the great similarity in the spectral profile as well as digital image profile of each type of feedstock employed in biodiesel production. Once the marketed diesel-biodiesel blend is subsidized, in which motivates adulteration in biofuel blend by cheaper supplies with high solubility to obtain profits associated with the subsidies involved in biodiesel production. Non-destructive analytical methods based on qualitative and quantitative analysis for detecting marketed diesel-biodiesel blend adulteration are reviewed...

BACKGROUND: We evaluated the safety and efficacy of low-egg-allergen cookies (LAC) as low-dose oral immunotherapy (OIT) in children with severe egg allergy. We also examined the relationship between mild desensitization by low-dose OIT and serum biomarkers of allergy. METHODS: We enrolled 13 children with egg allergy who could not receive OIT with hard-boiled egg white (EW). For 11 participants, OIT was carried out using LAC for 3-4 months. Open food challenges with hard-boiled EW and blood samplings were performed before and after OIT...

While agriculture places the greatest demand on water resources, increasing agricultural production is worsening a global water shortage. Reducing the cultivation of water-consuming crops may be the most effective way to reduce agricultural water use. However, when also taking food demand into consideration, sustaining the balance between regional water and food securities is a growing challenge. This paper addresses this task for regions where water is unsustainable for food production (Beijing-Tianjin-Hebei Region for example) by: (i) assessing the different effects of wheat and maize on water use; (ii) analyzing virtual water and virtual land flows associated with food imports and exports between Beijing-Tianjin-Hebei and elsewhere in China; (iii) identifying sub-regions where grain is produced using scarce water resources but exported to other regions; and (iv) analyzing the potentiality for mitigating water shortage via Land-Water-Food Nexus...

Quantitative risk assessment for food allergens has made considerable progress in recent years, yet acceptability of its outcomes remains stymied because of the limited extent to which it has been possible to incorporate severity as a variable. Reaction severity, particularly following accidental exposure, depends on multiple factors, related to the allergen, the host and any treatments which might be administered. Some of these factors are plausibly still unknown. Quantitative risk assessment shows that limiting exposure through control of dose reduces the rates of reactions in allergic populations, but its impact on the relative frequency of severe reactions at different doses is unclear...

Despite continuous advances in analytical and physiological knowledge, the comprehension of an aroma is still a challenge. Gas chromatography coupled to olfactometry (GC-O) is an efficient method to identify and estimate individual potential of odorants, but there is a gap between this individual characterization and the effective contribution of compounds in the mixture, which is due to complex chemical and perceptual interactions. Therefore, recombination and omission experiments are often performed to achieve an understanding of food aromas...

INTRODUCTION: Food allergy is an increasing health problem in the developed world. Cow's milk protein is the main cause of food allergy in infants. Without an appropriate diagnostic workup, there is a high risk of both over- and underdiagnosis and therefore, over and undertreatment. The objective of our study was to analyze the variability in cow's milk protein allergy (CMPA) management by pediatric gastroenterologists in Spain. METHODS: A fifty item questionnaire, including open and closed items in a Likert's scale from 0 to 5, was drafted and distributed through the Spanish Society for Pediatric Gastroenterology, Hepatology and Nutrition (SEGHNP) e-mail list...

Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), both abundant in fish oil, are known to have significant biochemical and physiological effects primarily linked to the improvement of human health, especially cardiovascular and brain health. However, the incorporation of fish oil into foods and beverages is often challenging, as fish oil is very easily oxidized and can cause undesirable flavors. This review discusses this rapid formation of the fishy and metallic off-flavors, focusing especially on an early stage of fish oil oxidation...

The design of new food products and increased agricultural activities have produced a diversity of waste streams or by-products that contain a high load of organic matter. The underutilization of these streams presents a serious threat to the environment and to the financial viability of the agricultural sector and the food industry. Oleaginous microorganisms, such as yeast and microalgae, have been used to convert the organic matter present in many agricultural waste streams into an oil-rich biomass. Filamentous fungi are promising oleaginous microorganisms because of their high lipid accumulation potential and simple biomass recovery, the latter being related to their pellet-like growth morphology in submerged cultivation...

Saliva is a complex multifunctional fluid that bathes the oral cavity to assist in soft and hard tissue maintenance, lubrication, buffering, defence against microbes and initiating digestion of foods. It has been extensively characterised in humans but its protein composition in dogs remains poorly characterised, yet could explain (patho) physiological differences between individuals, breeds and with humans. This pilot discovery study aimed to characterise canine saliva from two breeds, Labrador retrievers and Beagles, and to compare this with human saliva using quantitative mass spectrometry...

Relating biodiversity to ecosystem functioning in natural communities has become a paramount challenge as links between trophic complexity and multiple ecosystem functions become increasingly apparent. Yet, there is still no generalised approach to address such complexity in biodiversity-ecosystem functioning (BEF) studies. Energy flux dynamics in ecological networks provide the theoretical underpinning of multitrophic BEF relationships. Accordingly, we propose the quantification of energy fluxes in food webs as a powerful, universal tool for understanding ecosystem functioning in multitrophic systems spanning different ecological scales...

Intake, absorption and synthesis of fatty acids, including those produced by the intestinal microbiota are tightly monitored via specific receptors and, indirectly through their conversion into a variety of signalling molecules. The resulting information is integrated and translated to different physiological processes, including the regulation of appetite and satiation. Direct chemosensing of fatty acids takes place via interaction with free fatty acid (FFA) and other receptors. These are present in the oronasal cavity and along the entire gastrointestinal tract, in various other tissues, and, for some receptors also in brain...

In Switzerland, the federal authorities, the cantons, and the communes share the responsibility of healthcare, disease prevention and health promotion policies. Yet, the cantons are in most health matters independent in their decisions, thus defining as a matter of fact their own health priorities. We examined and analysed the content of the disease prevention and health promotion plans elaborated during the last decade in six French-speaking cantons with different political contexts and resources, but quite similar population health data, in order to identify the set health priorities...

Cervical total disc replacement (cTDR) is still considered a developing technology, with widespread clinical use beginning in the early 2000s. Despite being relatively new to the marketplace, the literature surrounding cTDR is abundant. We conducted a thorough review of literature published in the United States (US) and outside the US to report the current global state of cTDR research and clinical use. Search criteria were restricted to publications with a clinical patient population, excluding finite element analyses, biomechanical studies, cadaver studies, surgical technique-specific papers, and case studies...

Regulatory agencies and government authorities have established maximum residue limits (MRL) in various food matrices of animal origin for supporting governments and food operators in the monitoring of veterinary drug residues in the food chain, and ultimately in the consumer's plate. Today, about 200 veterinary drug residues from several families, mainly with antibiotic, antiparasitic or anti-inflammatory activities, are regulated in a variety of food matrices such as milk, meat or egg. The current article provides a review of the regulatory framework in milk and muscle including data from Codex Alimentarius, Europe, USA, Canada and China for about 220 veterinary drugs...

Toronto has the largest absolute number of food insecure households for any metropolitan census area in Canada: of its 2.1 million households, roughly 252 000 households (or 12%) experience some level of food insecurity. Community organizations (including social agencies, school programs, and child care centres) serve millions of meals per year to the city's most vulnerable citizens, but often face challenges accessing fresh produce at affordable prices. Therefore in 2015, Toronto Public Health, in collaboration with public- and private-sector partners, launched the FoodReach program to improve the efficiency of food procurement among community organizations by consolidating their purchasing power...

Recreation and sport settings (RSS) typically promote health in the form of physical activity, but the healthfulness of their food environment is often neglected. We explored stakeholder perspectives on barriers to healthy food provision in RSS through telephone interviews with ten representatives from RSS across Nova Scotia. Three key barriers were identified: 1) cultural norms associated with food in RSS and the broader environment, 2) the persisting notion of personal choice and responsibility, and 3) financial implications of healthy food provision...

Rapid progress in genome sequencing technology has put us firmly into a postgenomic era. A key challenge in biomedical research is harnessing genome sequence to fulfill the promise of personalized medicine. This Review describes how genome sequencing has enabled the identification of disease-causing biomolecules and how these data have been converted into chemical probes of function, preclinical lead modalities, and ultimately U.S. Food and Drug Administration (FDA)-approved drugs. In particular, we focus on the use of oligonucleotide-based modalities to target disease-causing RNAs; small molecules that target DNA, RNA, or protein; the rational repurposing of known therapeutic modalities; and the advantages of pharmacogenetics...

During evolution, individuals whose brains and bodies functioned well in a fasted state were successful in acquiring food, enabling their survival and reproduction. With fasting and extended exercise, liver glycogen stores are depleted and ketones are produced from adipose-cell-derived fatty acids. This metabolic switch in cellular fuel source is accompanied by cellular and molecular adaptations of neural networks in the brain that enhance their functionality and bolster their resistance to stress, injury and disease...
