Greater food variety is related to increased energy intake, and one approach to reduce food intake is to reduce food variety. The effects of varying the variety of foods at the dinner meal to reduce energy intake was assessed in laboratory and field experiments. Experiment 1 randomly assigned 31 overweight children to one of three conditions that provided one laboratory meal per day over a week...

background and objectives evaluation of protein quality in food is of great importance due to the biological and economical impacts of food proteins. this study has been conducted with the aim of comparing the protein quality of homemade food (mixture of macaroni and soy bean) with commercial baby food (cerelac wheat) using casein as the refference point.   methods this study was conducted on 6...

On Bird Island, South Georgia, albatrosses (n = 140), penguins (n = 100), and fur seals (n = 206) were sampled for Campylobacter jejuni. C. jejuni subsp. jejuni was recovered from three macaroni penguins (Eudyptes chrysolophus). These isolates, the first reported for the subantarctic region, showed low genetic diversity and high similarity to Northern Hemisphere C. jejuni isolates, possibly sug...

Although penguins are key marine predators from the Southern Ocean, their migratory behaviour during the inter-nesting period remains widely unknown. Here, we report for the first time, to our knowledge, the winter foraging movements and feeding habits of a penguin species by using geolocation sensors fitted on penguins with a new attachment method. We focused on the macaroni penguin Eudyptes c...

macaroni is one of the favorite dishes in iranian,s family food program. in this study, effects of using different level of curcumin as a natural and functional component extracted from curcuma longa plant, against total count , total coliforms, psychrotrophic bacteria, yeasts and moulds and colorimetric properties of macaroni in comparison with beta carotene and turmeric as commercial color ad...

Heart rate (fH), abdominal temperature (T(ab)) and diving depth were measured in thirteen free-ranging breeding female macaroni penguins. Measurement of these variables allowed estimation of the mass-specific rate of oxygen consumption (V(O(2))) while diving and investigation of the physiological adjustments that might facilitate the diving behaviour observed in this species. In common with oth...
