  • *Indicates data estimated from graphical representation. Note that the categories 'raw' and 'homemade' can overlap, as in the case of a homemade diet containing raw animal products. In previous studies, this distinction is not made, so homemade raw food could be represented both under 'raw' and under 'homemade' categories, for the data from the present study, raw homemade food is categorised simply as 'raw'. Particular foods were considered to be exclusively fed if the study reported that food as the only food fed or that the diet comprised solely that food. Alternatively, foods were considered to be inclusive in the diet if the study reported that other foods were also fed or that the diet comprised more than one food.
