1. Biogenic amines in Portuguese traditional foods and wines.
Match Strength: 6.358
The presence of biogenic amines in foodstuffs is an important food safety problem because of the implication of these compounds in food intolerance and intoxication. The separation and quantification of biogenic amines in foods is normally performed by chromatographic techniques. This review contains descriptions of the quantification of biogenic amines in Portuguese traditional fermented and/or ripened foods and wines, including Protected Denomination of Origin cheeses, dry-cured sausages, and Portuguese wines (including Port wines), using different analytical methods based on high-pressure ...

2. A new statistical method for estimating the usual intake of episodically consumed foods with application to their distribution.
Match Strength: 5.619
OBJECTIVE: We propose a new statistical method that uses information from two 24-hour recalls to estimate usual intake of episodically consumed foods. STATISTICAL ANALYSES PERFORMED: The method developed at the National Cancer Institute (NCI) accommodates the large number of nonconsumption days that occur with foods by separating the probability of consumption from the consumption-day amount, using a two-part model. Covariates, such as sex, age, race, or information from a food frequency questionnaire, may supplement the information from two or more 24-hour recalls using correlated mixed model ... Read More »

3. Physician and patient barriers to adherence with cholesterol guidelines.
Match Strength: 5.395
Several national studies have shown poor compliance with National Cholesterol Education Program II (NCEP) goals. A study we conducted of patients in the General Internal Medicine Clinic at the Marshall University Joan C. Edwards School of Medicine in Huntington showed that 46% of them were not at NCEP goals. We hypothesized that both patient and physician barriers were responsible for these findings so we administered two surveys about barriers to cholesterol management to 261 random patients identified with hypercholesterolemia and to all 50 residents and faculty at the clinic. We identified ... Read More »

4. The food propensity questionnaire: concept, development, and validation for use as a covariate in a model to estimate usual food intake.
Match Strength: 5.190
OBJECTIVE: Twenty-four-hour recalls capture rich information on food consumption, but suffer from inadequately measuring usual intakes of episodically consumed foods. We explore using food frequency questionnaire (FFQ) data as covariates in a statistical model to estimate individual usual intakes of episodically consumed foods and their distributions and describe the development of the Food Propensity Questionnaire, an FFQ introduced in the 2003-2004 National Health and Nutrition Examination Survey. DESIGN: We analyzed data from 965 adult participants in the Eating at America's Table Study who ... Read More »

5. Vitamin D, aging, and the 2005 Dietary Guidelines for Americans.
Match Strength: 5.004
The 2005 Dietary Guidelines for Americans recommend that older adults, people with dark skin, and those exposed to insufficient ultraviolet radiation (i.e., sunlight) consume extra vitamin D from vitamin D-fortified foods and/or supplements. Individuals in these high-risk groups should consume 25 microg (1000 IU) of vitamin D daily to maintain adequate blood concentrations of 25-hydroxyvitamin D, the biomarker for vitamin D status. This review considers recommendations for vitamin D-rich foods and dietary supplements, as well as specific problems with self-prescribing sun exposure or ... Read More »

6. Dietary exposure of children and teenagers to benzoates, sulphites, butylhydroxyanisol (BHA) and butylhydroxytoluen (BHT) in Beirut (Lebanon).
Match Strength: 4.913
The acceptable daily intake (ADI) for a considered chemical is by definition the amount of that substance which can be ingested every day during the life time without appreciable health risk. The theoretical risk of exceeding the ADI for benzoates, sulphites, butylhydroxyanisol (BHA) and butylhydroxytoluen (BHT) has often been examined on the basis of worst case scenario. The aim of this paper is to assess the actual intake of the food additives listed above for a group of the Lebanese population (students aged between 9 and 18 years old) likely to be highly exposed to food additives through ...

7. Surface binding of aflatoxin B1 by Saccharomyces cerevisiae strains with potential decontaminating abilities in indigenous fermented foods.
Match Strength: 4.717
Saccharomyces cerevisiae constitutes one of the most important microorganisms involved in food fermentations throughout the world. Aflatoxin B(1) binding abilities of S. cerevisiae strains isolated from indigenous fermented foods from Ghana, West Africa were tested in vitro. Results show that aflatoxin binding was strain specific with 7 strains binding 10-20%, 8 strains binding 20-40% and 3 strains binding more than 40% of the added aflatoxin B(1) when grown and incubated under standard conditions. Binding by two of the strains was further characterized. Highest binding capacity was seen with ... Read More »

13. Prevalence, consequences and prevention of childhood nutritional iron deficiency: a child public health perspective.
Match Strength: 3.609
The true extent of nutritional iron deficiency (ID) in childhood is unclear because of uncertainty over its definition and the insensitivity of markers of ID. The major cause is likely to be the excessive and early use of cow's milk. Recent neurophysiological observations support the many field studies correlating ID with cognitive developmental delays. Prevention is best sought through supplementation of essential foods. Publication Types: ... Read More »

15. Ecological half-lives of 90Sr and 137Cs in terrestrial and aquatic ecosystems.
Match Strength: 2.777
This paper describes the long-term behaviour of (90)Sr and (137)Cs in foods, feeds and a variety of environmental media. The long-term behaviour is quantified by means of the ecological half-life which integrates all processes that cause a decrease of activity in a given medium such as leaching, fixation and erosion. A large number of long-term time series of concentrations of radiocaesium and radiostrontium in these media have been identified and re-evaluated using a standardised statistical procedure to establish reference data sets of ecological half-lives. By example of undisturbed soils ... Read More »

16. DNA-DNA cross-links contribute to the mutagenic potential of the mycotoxin patulin.
Match Strength: 2.720
The mycotoxin patulin (PAT), which occurs in various foods, induces mutations in cultured mammalian cells. However, the mechanism underlying the mutagenic potential of PAT is far from clear. In order to further clarify the mutagenic mode of action of PAT, we investigated the potential of PAT to induce DNA strand breaks, oxidative DNA modifications, and DNA-DNA cross-links using an alkaline filter elution technique and a fluorescence-based assay. In concentrations known to induce mutations in V79 cells (0.5-2.5 microM), PAT also induced DNA-DNA cross-links. In contrast, no effect on the number ... Read More »

17. Computational detection of allergenic proteins attains a new level of accuracy with in silico variable-length peptide extraction and machine learning.
Match Strength: 2.429
The placing of novel or new-in-the-context proteins on the market, appearing in genetically modified foods, certain bio-pharmaceuticals and some household products leads to human exposure to proteins that may elicit allergic responses. Accurate methods to detect allergens are therefore necessary to ensure consumer/patient safety. We demonstrate that it is possible to reach a new level of accuracy in computational detection of allergenic proteins by presenting a novel detector, Detection based on Filtered Length-adjusted Allergen Peptides (DFLAP). The DFLAP algorithm extracts variable length ... Read More »

18. Genetics of obesity and the prediction of risk for health.
Match Strength: 2.425
Obesity has always existed in human populations, but until very recently was comparatively rare. The availability of abundant, energy-rich processed foods in the last few decades has, however, resulted in a sharp rise in the prevalence of obesity in westernized countries. Although it is the obesogenic environment that has resulted in this major healthcare problem, it is acting by revealing a sub-population with a pre-existing genetic predisposition to excess adiposity. There is substantial evidence for the heritability of obesity, and research in both rare and common forms of obesity has ... Read More »

20. Iron dissociates from the NaFeEDTA complex prior to or during intestinal absorption in rats.
Match Strength: 2.368
Sodium iron ethylenediaminetetraacetate (NaFeEDTA) has superior iron bioavailability especially in foods containing iron absorption inhibitors. However, mechanisms involved in the absorption and subsequent partitioning of iron complexed with EDTA are poorly understood. Our objectives were to compare retention and tissue distribution of iron administered to rats either as FeSO4 or NaFeEDTA, either orally (OR) or subcutaneously (SC). Weanling rats were fed semipurified diets supplemented with either FeSO4 or NaFeEDTA for 7 days. They were then given a meal containing 59Fe-labeled FeSO4 or ... Read More »
