A prospective study of food variety seeking in childhood, adolescence and early adult life

2005

Publication Inra prise en compte dans l'analyse bibliométrique des publications scientifiques mondiales sur les Fruits, les Légumes et la Pomme de terre. Période 2000-2012. http://prodinra.inra.fr/record/256699; International audience; This prospective study of food variety seeking among children was conducted between 1982 and 1999, with a follow-up in 2001–2002. Two- to three-year-old children were given a free choice of lunch foods in a nursery canteen. Their food choices were recorded and used to calculate early variety seeking scores, globally and by food group (vegetables, animal products, dairy products, starchy foods and combined dishes). The same subjects (n=339) were contacted in 2…

Dairy Consumption and Incidence of Breast Cancer in the 'Seguimiento Universidad de Navarra' (SUN) Project.

2021

Dairy products might influence breast cancer (BC) risk. However, evidence is inconsistent. We sought to examine the association between dairy product consumption—and their subtypes—and incident BC in a Mediterranean cohort. The SUN (“Seguimiento Universidad de Navarra”) Project is a Spanish dynamic ongoing cohort of university graduates. Dairy product consumption was estimated through a previously validated 136-item food frequency questionnaire (FFQ). Incident BC was reported in biennial follow-up questionnaires and confirmed with revision of medical records and consultation of the National Death Index. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated with Cox regression …

Plant Sterols and Antioxidant Parameters in Enriched Beverages: Storage Stability

2012

Plant sterols (PS) stability, antioxidant parameters, and color were studied during 6 months of storage at 4, 24, and 37 °C in three PS-enriched functional beverages. Beverages were skimmed milk with fruit juice and PS (MFJPS), fruit juice and PS (FJPS), and skimmed milk with PS (MPS). No loss in total PS content occurred during storage observing the same values at any given storage time point. Total carotenoids decreased 36% with storage at two months and then remained stable. Total polyphenols showed fluctuations throughout the storage, remaining stable at 6 months and reaching initial values. The antioxidant capacity (TEAC method) increased 18% at 6 months, and there was an increase in c…

Biogenic amines in fermented foods

2010

Food-fermenting lactic acid bacteria (LAB) are generally considered to be non-toxic and non-pathogenic. Some species of LAB, however, can produce biogenic amines (BAs). BAs are organic, basic, nitrogenous compounds, mainly formed through decarboxylation of amino acids. BAs are present in a wide range of foods, including dairy products, and can occasionally accumulate in high concentrations. The consumption of food containing large amounts of these amines can have toxicological consequences. Although there is no specific legislation regarding BA content in many fermented products, it is generally assumed that they should not be allowed to accumulate. The ability of microorganisms to decarbox…

Determination of sialic acid and gangliosides in biological samples and dairy products: A review

2009

Gangliosides are sphingolipids containing one or more moieties of sialic acid in their structure. Both gangliosides and sialic acid are bioactive compounds related to animal physiology. Due to their biological relevance, analytical methods adapted to each type of matrix have been developed over time. The present study reviews the main methods applied to the analysis of sialic acid and gangliosides in biological samples and dairy products.

Congener profile, occurrence and estimated dietary intake of dioxins and dioxin-like PCBs in foods marketed in the Region of Valencia (Spain).

2011

During 2006-2008, a monitoring program was conducted on 29 target compounds, including PCDD/Fs and dl-PCBs, comprising 150 randomly collected individual food samples marketed in the Region of Valencia, Spain, grouped into 8 categories (vegetables, cereals, fats and oils, eggs, milk and dairy products, fish products, meat and meat products and fish oil). For PCDD/Fs, the highest frequency of detection corresponds to 1,2,3,4,6,7,8-HpCDD, OCDD, 2,3,4,7,8-PeCDF; and PCBs 118, 105 and 156 were the more frequent dl-PCBs. The food groups presenting higher contamination, expressed as toxic equivalents (WHO-TEQs), were fish oil (6.38 pg WHO-TEQ g(-1)fat), fish (1.21 pg WHO-TEQ g(-1)w.w.) and milk an…

New Trends in Molecular Techniques to Identify Microorganisms in Dairy Products

2018

International audience; Dairy products constitute one of the most important types of functional foods. Most of these functional properties have been attributed to their complex microbial ecosystem. Moreover, microorganisms are responsible for the broad diversity of tastes, aromas, and textures of dairy products. For instance, many bacteria make a positive contribution to the organoleptic quality of cheeses or fermented milk. However, some other bacteria may have adverse effects, or may even present a health risk from a safety point of view. Thus, it is of a paramount importance to control microbial ecosystem of dairy products. Traditionally culture-based methods have been used for the ident…

Staphylococcal food poisoning case and molecular analysis of toxin genes in Staphylococcus aureus strains isolated from food in Sicily, Italy.

2014

A case of staphylococcal food poisoning was observed in two individuals of the same family after consumption of primosale, a semiripened sheep cheese produced in Sicily. Staphylococcus aureus isolated from the cheese produced enterotoxin C (SEC) and carried both the enterotoxin C (sec) and the toxic shock syndrome toxin (tsst-1) gene. Following this case, an extensive survey was conducted on 971 food samples (raw milk, cheese, meat, and food preparations). S. aureus was detected in 102 of 971 food samples, from all types of food with the exception of ricotta cheese. The tsst-1 gene was present in 42% of the strains, either alone or in combination with other toxin genes. The enterotoxin C ge…

In vitro digestion of two age-tailored dairy products in the aging gastrointestinal tract

2023

For older adults (> 65 years old), undernutrition is a severe health problem that can impact the quality of life, induce or aggravate the development of diseases, and reduce life expectancy. Undernutrition can be defined as an inadequate intake of dietary energy and proteins combined with a low muscle mass. Diet-induced muscle mass and strength loss in older adults may be due to insufficient protein intake. Therefore, older adults need to increase the amount of high-quality ingested proteins, particularly foods rich in leucine, to promote muscle health. However, it is still unclear if changes in protein digestibility and absorption kinetics in old age may affect the anabolic effect of high-…
