Effect of phenylpropanolamine on diet selection in rats
Pharmacology Biochemistry and Behavior, 1988Four doses of phenylpropanolamine (PPA; i.e., dl-norephedrine: 2.5, 5, 10, and 20 mg/kg) and saline were injected intraperitoneally in female rats maintained on a dietary self-selection paradigm. Intake of all three macronutrients (carbohydrate, fat, and protein) was equally affected by high doses of PPA. Lower doses decreased fat and protein more than

Zinc and copper in self-selected diets
Journal of the American Dietetic Association, 1979Levels of zinc and copper in the self-selected diets of twenty-two men and women were determined by atomic absorption spectrophotometry. Sixty-eight per cent of the subjects consumed less than two-thirds of the recommended allowance for zinc (15 mg). Eighty-one per cent consumed less than two-thirds of the suggested level of copper (2.0 mg).

Selected Aspects of Mediterranean Diet and Cancer Risk
Nutrition and Cancer, 2009European Mediterranean populations have a high life expectancy. Several aspects of their diet are considered favorable on health. We considered the role of various aspects of the Mediterranean diet on cancer risk in a series of Italian case-control studies including about 10,000 cases of cancer at 13 different sites and over 17,000 controls.

Neuroecology and diet selection in phyllostomid bats
Behavioural Processes, 2009(Uploaded by Plazi for the Bat Literature Project) For many birds and mammals relative brain and hippocampus volume are positively related to enhanced behavioral flexibility and spatial memory. I tested for correlations between species-specific diet selection and relative brain and hippocampus volumes in the New World leaf-nosed bats (Phyllostomidae ...

Diet Selection on Depletable Resources
Oikos, 1989We tested a number of patch use and diet choice strategies using natural populations of kangaroo rats, Dipodomys merriami. Patch use strategies included leaving patches: 1) at a fixed quitting harvest rate, 2) after a fixed search time, and 3) after a fixed amount of harvest.

Man, being a social animal living in a wide range of habitats and consuming a highly varied diet, challenges any simple definition of his food requirements. For example a traditional daily Kikuyu diet contains approximately 22 g of fat and 390 g of carbohydrate.

Vigilance and diet selection: The classical diet model reconsidered
Journal of Theoretical Biology, 1988A simple diet model is developed that explicitly considers an animal's need to be vigilant for predators while foraging. The currency of fitness is survival over some time period rather than energy intake rate per se. The model considers vigilance both while searching for and consuming prey items.
