OBJECTIVE To identify food sources of nutrients in adolescents' diets and to identify differences in food sources according to individual characteristics. DESIGN A cross-sectional evaluation was carried out in the 2003/2004 school year. Self-administered questionnaires were used and a physical examination was performed. Diet was evaluated using an FFQ. SETTING Public and private schools in ...

Epidemiological studies suggest that a diet high in processed meat, with a high glycemic index is associated with an increased risk of type 2 diabetes. It is not clear if this is due to altered insulin sensitivity or an enhanced postprandial glucose. We aimed to compare the acute metabolic response of two different types of meals after ingestion of the matching diet for four weeks. The study wa...

Conjugated linoleic acids (CLA) are natural constituents of meat and dairy products from ruminants, originating from bacterial biohydrogenation in the rumen. CLA supplementation increases the health benefits of animal-derived foods. There are inconsistent reports of the effects of dietary CLA on chicken’s performance; however, the majority of previous reports cite anti-lipogenic effects of CLA....

In pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. Basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...

Conjugated linoleic acid is a group of positional and geometrical isomers of linoleic acid (C18:2, cis-9, cis-12), an essential fatty acid for human and animals. It is produced in ruminants via biohydrogenation of poly-unsaturated fatty acids and during the mechanical processing of dairy products. Meat and dairy products from ruminant animals (such as milk, butter, yogurt and cheese) are the pr...

BACKGROUND Dietary fats could affect glucose metabolism and obesity development and, thereby, may have a crucial role in the cause of type 2 diabetes (T2D). Studies indicated that replacing saturated with unsaturated fats might be favorable, and plant foods might be a better choice than animal foods. Nevertheless, epidemiologic studies suggested that dairy foods are protective. OBJECTIVE We h...

In the hope of developing a vaccine against Clostridium difficile based on its toxin(s), we have developed a fermentation medium for the bacterium that results in the formation of Toxin A and contains no meat or dairy products, thus obviating the problem of possible prion diseases. Particular preparations of hydrolyzed soy proteins, especially Soy Peptone A3, have been found to replace both the...
