Answers
Food biodiversity is defined as "the diversity of plants, animals and other organisms used for food, covering the genetic resources within species, between species and provided by ecosystems.
Food biodiversity can be considered from two main perspectives: production and consumption. From a consumption perspective, food biodiversity describes the diversity of foods in human diets and their contribution to dietary diversity, cultural identity and good nutrition. Production of food biodiversity looks at the thousands of food products, such as fruits, nuts, vegetables, meat and condiments sourced from agriculture and from the wild (e.g. forests, uncultivated fields, water bodies). Food biodiversity covers the diversity between species, for example different animal and crop species, including those considered neglected and underutilized species. Food biodiversity also comprises the diversity within species, for example different varieties of fruit and vegetables, or different breeds of animals.
Food diversity, diet diversity nutritional diversity, are also terms used in the new diet culture spawned by Brandon Eisler, in the study known as Nutritional Diversity.
