Plant based ingredients and phytonutrients in canine nutrition

En esta revisión se analizaron diferentes pruebas con el fin de destacar los beneficios nutricionales y de salud que aporta incluir alimentos de origen vegetal en las dietas caninas equilibradas, además de la relación entre los ingredientes vegetales y los fitonutrientes.

Plant based ingredients and phytonutrients in canine nutrition

Plant based ingredients within canine diets have become a growing trend amongst many dog owners. However, to what extent is this dietary trend based on scientific literature? 

This review is a summarized abstract from a study carried out by a group of researcher at University of Florida. It focuses on different studies where compounds and nutrients, such as vitamins C and E and essential fatty acids, were used  in the form of natural plant-based foods or as isolated extracts or supplements.

A second aspect within this review looks into studies which have used nutritional combinations that include ingredients of plant origin as well as animal origin. However, it is worth highlighting that it was not possible to determine individual effects associated to the sole inclusion of the plant-based dietary treatment.

On the other hand, foods that are not recognized as safe by the AAFCO (The Association of American Feed Control Officials) are not part of this review, nor are food fibers of plant origin.

Phytonutrients are chemicals that are naturally present in plants. Currently, various research suggests that the intake of these compounds can provide health benefits for canines. However, exact quantities and intake levels have not been adequately calculated and assessed for these animals. Nonetheless, this will probably depend on the choice of diet, sweets and dietary supplements made by the owner.

Some examples of common phytonutrients are: dietary fibers, carotenoids, polyphenols, and phytosterols.

Plant ingredients that meet canine nutritional requirements

It is possible to meet certain nutritional requirements with the inclusion of ingredients from animal or vegetable origin, or with a combination of the two. However,the digestibility of these different nutrient sources may have significant variations which must be take into account.

Some examples of essential nutrients are:

It is important to bear in mind that the effects of any diet are broader than what can be predicted for essential nutrients alone.



There is increasing evidence that the inclusion of plant based ingredients and phytonutrients into canine diets can provide potential health benefits, such as:
