Adolescence: macronutrient needs [PDF]

European Journal of Clinical Nutrition, 2000
Dietary needs during adolescence lack specific definitions, and most evidence is derived from indirect indications. The data on dietary needs for energy and proteins are mainly extrapolated from subjects in other age-classes. Lipids and carbohydrates are being progressively considered for preventive purposes since the qualitative distribution of ...

Macronutrient composition of sea otter diet with respect to recolonization, life history, and season in southern Southeast Alaska

Ecology and Evolution, 2023
The sea otter (Enhydra lutris) population of Southeast Alaska has been growing at a higher rate than other regions along the Pacific coast. While good for the recovery of this endangered species, rapid population growth of this apex predator can create a

Balancing macronutrient intake in a mammalian carnivore: disentangling the influences of flavour and nutrition [PDF]

Royal Society Open Science, 2016
There is a large body of research demonstrating that macronutrient balancing is a primary driver of foraging in herbivores and omnivores, and more recently, it has been shown to occur in carnivores. However, the extent to which macronutrient selection in
